1. Casks authorized by thiis certificate are hereby approved for use by holders of 10 CFR Part 50 licenses for nuclear power reactors at reactor sites under the general license issued pursuant to 10 CFR 72.210 subject to the conditions specified byA10CFR 72'.212 and the attached Technical Specifications.

2. The holder of this certificate who desires to change the certificate or Technical Specifications shall submit an application for amendment of the certificate or Technical Specifications.

3. CASK:

a. Model Nos. Standardized NUHOMS-24P, -52B, -61BT,-32PT, -24PHB,-24PTH,-32PTH1 and

-61 BTH The two digits refer to the number of fuel assemblies stored in the dry shielded canister (DSC), the character P for pressurized water reactor (PWR) or B for boiling water reactor (BWR) is to designate the type of fuel stored, and T is to designate that the DSC is intended for transportation in a 10 CFR Part 71 approved package. The characters H or HB refer to designs qualified for fuel with burnup greater than 45 GWd/Mtu.

b. Description The Standardized NUHOMS System is certified as described in the final safety analysis report (FSAR) and in the NRC's Safety Evaluation Report (SER). The Standardized NUHOMS System is a horizontal canister system composed of a steel dry shielded canister (DSC), a reinforced concrete horizontal storage module (HSM), and a transfer cask (TC). The welded DSC provides confinement and criticality control for the storage and transfer of irradiated fuel. The concrete module provides radiation shielding while allowing cooling of the DSC and fuel by natural convection during storage.

The TC is used for transferring the DSC from/to the Spent Fuel Pool Building to/from the HSM.

NRC FORM 651 U.S. NUCLEAR REGULATORY COMMISSION (10-2004) 10 CFR 72 CERTIFICATE OF COMPLIANCE Certificate No. 1004 FOR SPENT FUEL STORAGE CASKS Amendment No. 10 Supplemental Sheet Page 2 of 3 The principal component subassemblies of the DSC are the shell with integral bottom cover plate, bottom shield plug or shield plug assemblies, ram/grapple ring, top shield plug or shield plug assemblies, top cover plate, and basket assembly. The shell length is fuel-specific. The internal basket assembly for the 24P, 24PHB, and 52B DSCs is composed of guide sleeves, support rods, and spacer disks. This assembly is designed to hold 24 PWR fuel assemblies or 52 BWR assemblies.

An alternate basket assembly configuration, consisting of assemblies of stainless steel fuel compartments held in place by basket rails and a holdown ring, is designed to hold 61 BWR assemblies. The 32PT, and 32PTH1 DSC basket assembly configurations are similar, consisting of welded stainless steel plates or tubes that make up a grid of fuel compartments supported by aluminum basket rails, and are designed to accommodate 32 PWR assemblies. The 24 PTH DSC basket assembly configuration consists of stainless steel tubes supported by basket rails and is designed to accommodate 24 PWR assemblies.

The basket assembly aids in the insertion of the fuel asse"mblies, enhances subcriticality during loading operations, and provides structural supjport during a hy'pothetical drop accident. The DSC is designed to slide from the transfer cask into the HHSM and back without und"ue galling, scratching, gouging, or other damage to the sliding surfaces.,, ...

The HSM is a reinforced concrete unit with penetrations located at thetop' and bottom of the walls for air flow, and is designed to store DStswith up to 24.0 kW decay heat.: The penetrations are protected from debris intrusions by wire rmesh scfrbns"during storage operation..The DSC Support Structure, a structural steel frame with rails;i .is installed within the HSM.V- *An alternate version of the'HSM-H design has been provided to allow the use of the NUHOMS'system in locations where higher seismic levels exist.

The TC is designed and fabricated as a lifting device to meet NUREG-0612 and ANSI N14.6 requirements. It is Used for frantsrfer operations within-th6 Spent Fudel Pool Building and for transfer operations to/from the HSM. T-e TC is*ai cylindica I vessel.with a b6ttom end closure assembly and a bolted top cover plate.,; Two upper lifting trunnions:aree located near tle top of the cask for downending/uprighting and liftingof the cask in the Spent Fuel Pool Building: The lower trunnions, located near the base of tlhe cask,ý serve as the,'axisof..rotatifn dnduring downending/uprighting operations and as supports during tr'ansport to/from thel" depehdent Spent Fuel Storage Installation (ISFSI). The 32PT DSC is transferred in aTOC with a radial liquid neutron shield.,:_,,

With the exception of the TC, fuel transfer and auxiliary equipment'necessary for ISFSI operations are not included as part of the Standardized NUHOMS System referenced in this Certificate of Compliance (CoC). Such site-specific equipment may ihclude-,but!is: not limited to, special lifting devices, the transfer trailer, and the skid positioning system

c. Drawings The drawings for the Standardized NUHOMS System are contained in Appendices E, K, M, N, P, T and U of the FSAR.

d. Basic Components The basic components of the Standardized NUHOMS System that are important to safety are the DSC, HSM, and TC. These components are described in Section 4.2, Table K.2-8 (Appendix K), Table M.2-18 (Appendix M), Table P.2-17 (Appendix P), Section T.2.3 (Appendix T) and Section U.2.3 (Appendix U) of the FSAR.

4. Fabrication activities shall be conducted in accordance with a Commission approved quality assurance program which satisfies the applicable requirements of 10 CFR Part 72, Subpart G, and which is established, maintained, and executed with regard to the cask system.

5. Notification of fabrication schedules shall be made in accordance with the requirements of 10 CFR 72.232(d).

6. HSM-H concrete shall be tested for elevated temperatures to verify that there are no significant signs of spalling or cracking and that the concrete compressive strength is greater than that assumed in the structural analysis. Tests shall be performed at or above the calculated peak temperature and for a period no less than the 40 hour4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> duration of HSM-H blocked vent transient for components exceeding 350 degrees F.

7. The use of HSM-H thermal performance meihodoiogy' isallowed for evaluating HSM-H configuration changes except for changes to the HSM-H c'vity heig*ht" cavity width, elevation and cross-sectional areas of the HSM-H air inlet/outlet Vents, total outside height, length and width of HSM-H if these changes exceed 8% of their nominal design values shown on the approved CoC Amendment No. 8 drawings.

8. If it is necessary to engage aEt~Vecooling for the OS197FC-B or th6`OS200FC Transfer Casks during transfer of a loaded DSC, the approp'riate NRC Division of Splent Fuel Storage and Transportation Project Manager shall'be notified within 30 dayss,,via electronic-, correspondence, of the occurrence.

1.0 INTRODUCTION

This section presents the conditions which a potential user (general licensee) of the standardized NUHOMS system must comply with, in order to use the system under the general license in accordance with the provisions of 10 CFR 72.210 and 10 CFR 72.212. These conditions have either been proposed by the system vendor, imposed by the NRC staff as a result of the review of the FSAR, or are part of the regulatory requirements expressed in 10 CFR 72.212.

As referenced in this document, the term "HSM" is applicable to both the StandardizedHSM and the HSM-H modules unless the applicabilityof one of the Technical Specifications contained in this document is limited to a specific HSM model. Similarly, the term HSM-H is applicable to both the HSM-H and the "high seismic" option of the HSM-H unless the applicabilityof one of the Technical Specifications containedin this document is limited to a specific HSM-H model.

As referenced in this document, the term "Transfer Cask" or "TC" is applicableto the standardizedtransfer cask, the 0S197 type transfer cask, and the 0S200 type transfer cask unless the applicabilityof one of the Technical Specifications containedin this document is limited to a specific transfer cask model.

1.1 General Requirements and Conditions 1.1.1 Regulatory Requirements for a General License Subpart K of 10 CFR Part 72 contains conditions for using the general license to store spent fuel at an independent spent fuel storage installation at power reactor sites authorized to possess and operate nuclear power reactors under 10 CFR Part 50. Technical regulatory requirements for the licensee (user of the standardized NUHOMS system) are contained in 10 CFR 72.212(b).

Under 10 CFR 72.212(b)(2) requirements, the licensee must perform written evaluations, before use, that establish that: (1) conditions set forth in the Certificate of Compliance have been met; (2) cask storage pads and areas have been designed to adequately support the static load of the stored casks; and (3) the requirements of 10 CFR 72.104 "Criteria for radioactive materials in effluent and direct radiation from an ISFSI or MRS," have been met. In addition, 10 CFR 72.212(b)(3) requires that the licensee review the FSAR and the associated SER, before use of the general license, to determine whether or not the reactor site parameters (including earthquake intensity and tornado missiles), are encompassed by the cask design bases considered in these reports.

The requirements of 10 CFR 72.212(b)(4) provide that, as a holder of a Part 50 license, the user, before use of the general license under Part 72, must determine whether activities related to storage of spent fuel involve any unreviewed safety issues, or changes in technical specifications as provided under 10 CFR 50.59. Under 10 CFR 72.212(b)(5), the general license holder shall also protect the spent fuel against design basis threats and radiological sabotage pursuant to 10 CFR 73.55. Other general license requirements dealing with review of reactor emergency plans, quality assurance program, training, and radiation protection program must also be satisfied pursuant to 10 CFR 72.212(b)(6). Records and procedural requirements for the general license holder are described in 10 CFR 72.212(b)(7), (8), (9) and (10).

A-1

Without limiting the requirements identified above, site-specific parameters and analyses, identified in the SER, that will need verification by the system user, are as a minimum, as follows:

1. The temperature of 70'F as the maximum average yearly temperature with solar incidence for the 24P, 52B and 61BTDSCs. The average daily ambient temperature shall be 100°F or less for the 24P, 52B, 61BT, 32PT, 24PHB, 61BTH, and 24PTH DSCs. For the 32PTH1 DSC, the average daily ambient temperature shall be 106YF or less.

2. The temperature extremes either of 125°F with incident solar radiation (for the 24P, 52B, and 61BT DSCs) or 117°F with solar incidence (for the 32PT, 24PHB, 24PTH, 61BTH and 32PTH1 DSCs) and -407F with no solar incidence for storage of the DSC inside the HSM.

The 11 7°F extreme ambient temperature corresponds to a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> calculated average temperature of 102°Ffor the 32PTDSC only.

3. The horizontal and vertical seismic acceleration levels of 0.25g and 0.17g, respectivelyfor the systems using the StandardizedHSMs.

The horizontal and vertical seismic accelerationlevels for the HSM-H arepayload specific as describedbelow:

00.3g horizontal and 0. 2g verticalfor the 24PTHand 61BTH DSCs,

• 0.3g horizontal and 0.25g verticalfor the 32PTHJ DSC, and

• 1.Og horizontal and 1.Og verticalfor the "high-seismic" HSM-H option with 32PTHI DSC.

4. The analyzed flood condition of 15 fps water velocity and a height of 50 feet of water (full submergence of the loaded HSM DSC).

5. The potential for fire and explosion should be addressed, based on site-specific considerations.

6. The HSM foundation design criteria are not included in the FSAR. Therefore, the nominal FSAR design or an alternative should be verified for individual sites in accordance with 10 CFR 72.212(b)(2)(ii). Also, in accordance with 10 CFR 72.212(b)(3), the foundation design should be evaluated against actual site parameters to determine whether its failure would cause the standardized NUHOMS system to exceed the design basis accident conditions.

7. The potential for lightning damage to any electrical system associated with the standardized NUHOMS system (e.g., thermal performance monitoring) should be addressed, based on site-specific considerations.

8. If an independentspentfuel storage installationsite is located in a coastalsalt water marine atmosphere, then any load-bearingcarbon steel DSC support structure railcomponents of any associatedHSM-H shall be procuredwith a minimum 0. 20 percent copper contentfor corrosionresistance.

A-2

9. Any other site parameters or consideration that could decrease the effectiveness of cask systems important to safety.

In accordance with 10 CFR 72.212(b)(2), a record of the written evaluations must be retained by the licensee until spent fuel is no longer stored under the general license issued under 10 CFR 72.210.

1.1.2 Operating Procedures Written operating procedures shall be prepared for cask handling, loading, movement, surveillance, and maintenance. The operating procedures suggested generically in the FSAR should provide the basis for the user's written operating procedure. The following additional procedure requested by NRC staff should be part of the user operating procedures:

If fuel needs to be removed from the DSC, either at the end of service life or for inspection after an accident, precautions must be taken against the potential for the presence of damaged or oxidized fuel and to prevent radiological exposure to personnel during this operation. This can be achieved with this design by the use of the purge and fill valves which permit a determination of the atmosphere within the DSC before the removal of the inner top cover and shield plugs, prior to filling the DSC cavity with water (borated water for the 24P or 32PT or 24PHB or 24PTH or 32PTH1). If the atmosphere within the DSC is helium, then operations should proceed normally with fuel removal either via the transfer cask or in the pool. However, if air is present within the DSC, then appropriate filters should be in place to preclude the uncontrolled release of any potential airborne radioactive particulate from the DSC via the purge-fill valves. This will protect both personnel and the operations area from potential contamination. For the accident case, personnel protection in the form of respirators or supplied air should be considered in accordance with the licensee's Radiation Protection Program.

1.1.3 Quality Assurance Activities at the ISFSI shall be conducted in accordance with a Commission-approved quality assurance program which satisfies the applicable requirements of 10 CFR Part 50, Appendix B, and which is established, maintained, and executed with regard to the ISFSI.

1.1.4 Heavy Loads Requirements Lifts of the DSC in the TC must be made within the existing heavy loads requirements and procedures of the licensed nuclear power plant. The TC design has been reviewed under 10 CFR Part 72 and found to meet NUREG-0612 and ANSI N14.6. However, an additional safety review (under 10 CFR 50.59) is required to show operational compliance with NUREG-0612 and/or existing plant-specific heavy loads requirements.

1.1.5 Training Module A training module shall be developed for the existing licensee's training program establishing an ISFSI training and certification program. This module shall include the following:

1. Standardized NUHOMS Design (overview);

A-3

2. ISFSI Facility Design (overview);

3. Certificate of Compliance conditions (overview);

4. Fuel Loading, Transfer Cask Handling, DSC Transfer Procedures; and

5. Off-Normal Event Procedures.

1.1.6 Pre-Operational Testing and Training Exercise A dry run of the DSC loading, TC handling and DSC insertion into the HSM shall be held. This dry run shall include, but not be limited to, the following:

1. Functional testing of the TC with lifting yokes to ensure that the TC can be safely transported over the entire route required for fuel loading, washdown pit (decontamination area) and trailer loading.

2. DSC loading into the TC to verify fit and TC/DSC annulus seal.

3. Testing of TC on transport trailer and transported to ISFSI along a predetermined route and aligned with an HSM.

4. Testing of transfer trailer alignment and docking equipment. Testing of hydraulic ram to insert a DSC loaded with test weights into an HSM and then retrieve it.

5. Loading a mock-up fuel assembly into the DSC.

6. DSC sealing, vacuum drying, and cover gas backfilling operations (using a mock-up DSC).

7. Opening a DSC (using a mock-up DSC).

8. Returning the DSC and TC to the spent fuel pool.

1.1.7 Special Requirements for First System in Place The heat transfer characteristics of the cask system will be recorded by temperature measurements of the first DSC placed in service. The first DSC shall be loaded with assemblies, constituting a source of approximately 24 kW in HSM (approximately 40.8 kW in HSM-H). The DSC shall be loaded into the HSM, and the thermal performance will be assessed by measuring the air inlet and outlet temperatures for normal airflow. Details for obtaining the measurements are provided in Section 1.2.8, under "Surveillance."

A letter report summarizing the results of the measurements shall be submitted to the NRC for evaluation and assessment of the heat removal characteristics of the cask in place within 30 days of placing the DSC in service, in accordance with 10 CFR 72.4.

Should the first user of the system not have fuel capable of producing a 24 kW heat load (40.8 kW heat load for 24PTH or 32PTHJ DSC), or be limited to a lesser heat load, as in the case of BWR fuel, the user may use a lesser load for the process, provided that a calculation of the temperature difference between the inlet and outlet temperatures is performed, using the same methodology and inputs documented in the FSAR, with lesser load as the only exception. The calculation and the measured temperature data shall be reported to the NRC in accordance with 10 CFR 72.4. The calculation and comparison need not be reported to the NRC for DSCs that are subsequently loaded with lesser loads than the initial case. However, for the first or any other user, the process needs to be performed and reported for any higher heat sources, up to 24 kW for PWR fuel stored in the 24P or 32PT or 24PHB or 24PTH-S-LC; up to 40.8 kW for PWR fuel stored in the 24PTH-S or 24PTH-L or 32PTHJ, 19 kW for BWR fuel stored in the 52B, A-4

18.3 kW for BWR fuel stored in the 61BT, 22. 0 kWfor a Type 1 61BTH, and 31.2 kWfor a Type 2 61BTHDSC, which are the maximum allowed under the Certificate of Compliance for these specific DSCs. The NRC will also accept the use of artificial thermal loads other than spent fuel, to satisfy the above requirement.

1.1.8 Surveillance Requirements Applicability The specified frequency for each Surveillance Requirement is met if the surveillance is performed within 1.25 times the interval specified in the frequency, as measured from the previous performance.

For frequencies specified as "once," the above interval extension does not apply.

If a required action requires performance of a surveillance or its completion time requires period performance of "once per...," the above frequency extension applies to the repetitive portion, but not to the initial portion of the completion time.

Exceptions to these requirements are stated in the individual specifications.

1.1.9 Supplemental Shielding Supplemental shielding and engineered features (e.g., earthen berms, shield walls) that are used to ensure compliance with 10 CFR 72.104(a) by each general licensee are to be considered important to safety and must be appropriately evaluated under 10 CFR 72.212(b).

1.1.10 HSM-H Storage Configuration A minimum of two (2) HSM-Hs are required to be placed adjacent to each other for stability during design basis flood loads.

For the high seismic HSM-H option, a minimum of three (3) HSM-Hs must be connected with each other.

1.1.11 Hydrogen Gas Monitoringfor 61BTHand32PTH1DSCs For the 6IBTH and 32PTH1 DSCs, while welding the innertop cover plate duringloadingoperations, andwhile cuttingthe outer or inner top cover plates duringunloadingoperations,hydrogen monitoring ofthe space under the shieldplug in the DSC cavity is required,to ensure that the combustible mixture concentrationremains below theflammability limit.

1.1.12 Codes and Standards 1.1.12.1 HorizontalStorage Module (HSM-HIHSM-HS)

The StandardizedHSM-H and HSM-HS reinforcedconcrete are designedto meet the requirementsofAC1349-97.

ASME Code Alternativesfor the NUHOMSe-61BTHDSC Confinement Boundary (Concluded)

Reference ASME Code Code Requirement Exception, Justification & Compensatory Measures Section/Article The 61BTH is not a complete or "installed" pressure vessel until the top closure is weldedfollowing placement of Fuel Assemblies with the DSC. Due to the inaccessibilityof the shell and lower end closure welds following fuel loading and top closure welding, as an alternative, the pressure testing of the DSC is performed in two parts. The DSC shell (includingall longitudinal and circumferentialwelds) is pressure testedand examined at thefabricationfacility.

The shell to the inner top cover closure weld are All completedpressure pressure tested and examinedfor leakage in accordance NB-6100 and al i systems shall be with NB-6300 in the field.

6200 pressur sted The siphon/vent cover welds are not pressure tested; 0pressure tested these welds and the shell to the inner top cover closure weld are helium leak tested after the pressuretest.

Per NB-6324 the examinationfor leakage shall be done at a pressure equal to the greater of the designpressure or three-fourths of the test pressure. As an alternative, if the examinationfor leakage of thesefield welds, following the pressure test, is performed using helium leak detection techniques, the examinationpressuremay be reduced to . 1.5 psig. This is acceptable given the significantlygreatersensitivity of the helium leak detection method.

Applicability: The specification is applicable to all fuel to be stored in the standardized NUHOMS system.

Objective: The specification is prepared to ensure that the peak fuel rod cladding temperatures, maximum surface doses, and nuclear criticality effective neutron multiplication factor are below the design limits. Furthermore, the fuel weight and type ensures that structural conditions in the FSAR bound those of the actual fuel being stored.

Action: Each spent fuel assembly to be loaded into a DSC shall have the parameters listed in Tables 1-ia, 1-lb, 1-1c, 1-1d, i-1e, 1-1f, 1-1g, 1-1i, 1-ij, 1-11, 1-Im, 1-It, 1-1u, 1-1aa, and 1-1bb verified and documented.

Fuel not meeting this specification shall not be stored in the standardized NUHOMS system.

Surveillance: Prior to loading of a spent fuel assembly into a DSC, the identity of each fuel assembly shall be independently verified and documented.

Bases: The specification is based on consideration of the design basis parameters included in the FSAR and limitations imposed as a result of the staff review. Such parameters stem from the type of fuel analyzed, structural limitations, criteria for criticality safety, criteria for heat removal, and criteria for radiological protection. The standardized NUHOMS system is designed for dry, horizontal storage of irradiated light water reactor (LWR) fuel. The principal design parameters of the fuel to be stored can accommodate standard PWR fuel designs manufactured by Babcock and Wilcox (B&W), Combustion Engineering (CE), and Westinghouse (WE),

and standard BWR fuel manufactured by General Electric (GE),

Exxon/ANF, and FramatomeANP. The NUHOMS-24P and 52B systems are limited for use to these standard designs and to reload designs by other manufacturers as listed in Chapter 3 of the FSAR. The analyses presented in the FSAR are based on non-consolidated, zircaloy-clad fuel with no known or suspected gross breaches.

The thermal design criterion of the fuel to be stored is that the total maximum heat generation rate per assembly and BPRA or Control Components be such that the fuel cladding temperature is maintained within established limits during normal and off-normal conditions. For the NUHOMS-24P, 52B and 61 BT systems, fuel cladding temperature limits were established based on methodology in PNL-6189 and PNL-4835. For the NUHOMS-32PT, 24PHB and 24PTH systems, fuel cladding limits are based on ISG-1 1, Rev. 2 (Reference 3). For the NUHOMSe-61BTH system, NUHOMS-61BT system with Framatome-ANP 9x9 Version 9x9-2 (FANP9 9x9-2) fuel assemblies, and the NUHOMS-32PTH1 system, fuel cladding limits are based on ISG-1 1, Rev. 3 (Reference 4).

The radiological design criterion is that fuel stored in the NUHOMS system must not increase the average calculated HSM or transfer cask surface dose rates beyond those calculated for the 24P, 24PHB, 52B, 61BT, or 32PT canister full of design basis fuel assemblies with or without BPRAs. The design value average HSM and cask surface dose rates for the 24P and 52B canisters were calculated to be 48.6 mrem/hr and 591.8 mrem/hr respectively based on storing twenty four (24)

Babcock and Wilcox 15xl5 PWR assemblies (without BPRAs) with 4.0 wt. % U-235 initial enrichment, irradiated to 40,000 MWd/MTU, and having a post irradiation time of five years. To account for BPRAs, the fuel assembly cooling required times are increased to maintain the above dose rate limits.

Notes:

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsible for ensuring that uncertainties in fuel enrichment and burnup are correctly accounted for during fuel qualification.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an initial enrichment less than 2.0 wt. % U-235 must be qualified for storage using the alternate nuclear parameters specified in Table 1-la. Fuel with an initial enrichment greater than 4.0 wt. % U-235 is unacceptable for storage.

• Fuel with a burnup greater than 45 GWd/MTU is unacceptable for storage.

• Example: An assembly with an initial enrichment of 3.65 wt. % U-235 and a burnup of 42.5 GWd/MTU is acceptable for storage after a ten-year cooling time as defined at the intersection of 3.6 wt. % U-235 (rounding down) and 43 GWd/MTU (rounding up) on the qualification table.

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsible for ensuring that uncertainties in fuel enrichment and bumup are correctly accounted for during fuel qualification.

• For fuel assemblies reconstituted with up to 10 stainless steel rods, increase the indicated cooling time by 1.5 years. If more than 10 stainless steel rods are present, increase the indicated cooling time by 6 years.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an initial enrichment less than 1.1 and greater than 5.0 wt.% U-235 is unacceptable for storage.

" Fuel with a burnup greater than 45 GWd/MTU is unacceptable for storage

• Fuel with a burnup less than 10 GWd/MTU is acceptable for storage after 5-years cooling.

" Example: An assembly with an initial enrichment of 3.75 wt. % U-235 and a burnup of 41.5 GWd/MTU is acceptable for storage after a eight-year cooling time as defined by 3.7 wt. % U-235 (rounding down) and 42 GWd/MTU (rounding up) on the qualification table.

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsible for ensuring that uncertainties in fuel enrichment and burnup are correctly accounted for during fuel qualification.

• For fuel assemblies reconstituted with up to 10 stainless steel rods, increase the indicated cooling time by 1.5 years. If more than 10 stainless steel rods are present, increase the indicated cooling time by 6 years.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an initial enrichment less than 1.1 and greater than 5.0 wt.% U-235 is unacceptable for storage.

• Fuel with a bumup greater than 45 GWd/MTU is unacceptable for storage

• Fuel with a burnup less than 10 GWd/MTU is acceptable for storage after 5-years cooling.

• Example: An assembly with an initial enrichment of 3.75 wt. % U-235 and a burnup of 41.5 GWd/MTU is acceptable for storage after a sixteen-year cooling time as defined by 3.7 wt. % U-235 (rounding down) and 42 GWd/MTU (rounding up) on the qualification table.

• Use burnup and enrichment to lookup minimum cooling time in years. For fuel assemblies reconstituted with up to 10 stainless steel rods only, if the lookup cooling time is less than 9.0 years then a minimum cooling time of 9.0 years shall be used. Licensee is responsible for ensuring that uncertainties in fuel enrichment and burnup are correctly accounted for during fuel qualification.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an initial enrichment greater than 4.5 wt.% U-235 is unacceptable for storage.

• Fuel with a burnup less than 10 GWd/MTU is acceptable for storage after 5-years cooling.

• Example: An assembly with an initial enrichment of 3.75 wt. % U-235 and a burnup of 46.5 GWd/MTU is acceptable for storage after a 19.5 years cooling time as defined by 3.7 wt. % U-235 (rounding down) and 47 GWd/MTU (rounding up) on the qualification table.

• See Figure 1-8 for a description of zones.

• For assemblies fuel reconstituted with Zircaloy clad uranium-oxide rods use the assembly average enrichment to determine the minimum cooling time.

Licensee is responsible for ensuring that uncertainties in fuel enrichment and burnup are correctly accounted for during fuel qualification.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an initial enrichment greater than 4.5 wt.% U-235 is unacceptable for storage.

• Fuel with a burnup less than 10 GWd/MTU is acceptable for storage after 5-years cooling.

• Example: An assembly with an initial enrichment of 3.75 wt. % U-235 and a burnup of 46.5 GWd/MTU is acceptable for storage after a 8.3 years cooling time as defined by 3.7 wt. % U-235 (rounding down) and 47 GWd/MTU (rounding up) on the qualification table.

See Figure 1-8 for a description of zones.

For assemblies fuel reconstituted with Zircaloy clad uranium-oxide rods use the assembly average enrichment to determine the minimum cooling time.

Notes: Tables 1-3a through 1-3h:

• Burnup = Assembly Average burnup.

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsible for ensuring that uncertainties in fuel enrichment and burnup are correctly accounted for during fuel qualification.

• Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

• Fuel with an assembly average initial enrichment less than 0.7 wt. % U-235 (or less than the minimum provided above for each burnup) and greater than 5.0 wt.% U-235 is unacceptable for storage.

• Fuel with a burnup greater than 62 GWd/MTU is unacceptable for storage.

" Fuel with a burnup less than 10 GWd/MTU is acceptable for storage after 3-years cooling.

" WE 15x15 PLSAs shall be limited to a minimum assembly average initialenrichment of 1.2 wt. % U-235.

" See Figures 1-1 1 through 1-15 for the description of zones.

" For reconstitutedfuel assemblies with U0 2 rods and/or Zr rods or Zr pellets and/orstainless steel rods, use the assembly average equivalent enrichment to determine the minimum cooling time.

" The cooling times for damaged and intact assemblies are identical.

• Example: An intact fuel assembly without CCs, with a decay heat load of 1.7 kW or less, an initial enrichment of 3.65 wt. % U-235 and a burnup of 41.5 GWd/MTU is acceptable for storage after a 4.0 year cooling time as defined by 3.6 wt. % U-235 (rounding down) and 42 GWd/MTU (rounding up) in Table 1-3a.

• 0 0 Notes: Tables 1-4a through 1-4f.

B Rurnup = Assembly Average burnup.

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsiblefor ensuring that uncertainties in fiuel enrichment and burntup are correctly accountedfor duringfiielqualification.

" Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

" Fuel with an lattice average initial enrichment less than 0.9 (or less than the minimum provided above for each burnup) or greaterthan 5.0 wt. % U-235 is unacceptablefor storage.

• Fuel with a burnup greaterthan 62 GWd/MTU is unacceptablefor storage.

• Fuel with a burnup less than 10 GWd/MA1TU is acceptablefor storage after 3-years cooling.

• See Figure 1-17 through Figure 1-24for a description of the zones.

• For reconstitutedfitel assemblies with U0 2 rods and/or Zr rods or Zr pellets and/or stainless steel rods, use the assembly average equivalent enrichment to determine the minimum cooling time.

• The cooling timesfor damagedand intact assemblies are identical.

• Example.- An intactfuel assembly, with a decay heat load of 0. 22 kW or less, an initial enrichment of 3.65 wt. % U-235 and a burnup of 41.5 GWd/MTU is acceptablefor storage after a 24 year cooling time as defined by 3.6 wt. % U-235 (rounding down) and42 GWd/MTU (roundingup) in Table 1-4a.

Notes: Tables 1-5a through 1-5f

" Burnup = Assembly Average burnup.

• Use burnup and enrichment to lookup minimum cooling time in years. Licensee is responsiblefor ensuringthat uncertaintiesin fuel enrichment and burnup are correctly accountedfor duringfuel qualification.

" Round burnup UP to next higher entry, round enrichments DOWN to next lower entry.

" For afuel assembly with Control Components,for a given enrichment and burnup, increase the cooling time obtainedfrom an FQT by one year.

• Fuel with an assembly average initialenrichment less than 0. 7 (or less ti/an the minimum provided abovefor each burnup) and greaterthan 5.0 wt. % U-235 is unacceptablefor storage.

" Fuel with a burnup greaterthan 62 GWd/MTU is unacceptablefor storage.

• Fuel with a burnup less than 10 GWd/MTU is acceptablefor storage after 3-years cooling.

" See Figure 1-26 through Figure 1-28for a description of the Heat Load Zones.

• For reconstitutedfitelassemblies with U0 2 rods and/or Zr rods or Zr pellets and/or stainless steel rods, use the assembly average equivalent enrichment to determine the minimum cooling time.

" The cooling times for damagedand intact assemblies are identical.

" Example: An intactfuel assembly without CCs, with a decay heat load of 1.5 kW or less, an initial enrichment of 3.65 wt. % U-235 and a burnup of 41.5 GWd/MTU is acceptablefor storage after a 4.0 year cooling time as defined by 3.6 wt. % U-235 (rounding down) and 42 GWd/MTU (roundingup) in Table 1-5f If thefiel assembly has CCs, the minimum cooling time is increasedby an additionalone year, resulting infive year minimum cooling time prior to storage.

1.2.2 DSC Vacuum Pressure During Drying Limit/Specification:

Vacuum Pressure: _<3 mm Hg Time at Pressure: Ž30 minutes following evacuation Number of Pump-Downs: 2 Applicability: This is applicable to all DSCs. The term "inner top cover" as used in this and other Technical Specifications means either the inner top cover plate or the top shield plug assembly.

Objective: To ensure a minimum water content.

Action: If the required vacuum pressure cannot be obtained:

1. Confirm that the vacuum drying system is properly installed.

2. Check and repair, or replace, the vacuum pump.

3. Check and repair the system as necessary.

4. Check and repair the seal weld between the inner top cover and the DSC shell.

Surveillance: No maintenance or tests are required during normal storage. Surveillance of the vacuum gauge is required during the vacuum drying operation.

Bases: A stable vacuum pressure of *3 mm Hg further ensures that all liquid water has evaporated in the DSC cavity, and that the resulting inventory of oxidizing gases in the DSC is well below the 0.25 volume %.

A-114

1.2.3 24P and 52B DSC Helium Backfill Pressure Limit/Specifications:

Helium 2.5 psig +/- 2.5 psig backfill pressure (stable for 30 minutes after filling).

Applicability: This specification is applicable to 24P and 52B DSCs only.

Objective: To ensure that: (1) the atmosphere surrounding the irradiated fuel is a non-oxidizing inert gas; (2) the atmosphere is favorable for the transfer of decay heat.

Action: If the required pressure cannot be obtained:

1. Confirm that the vacuum drying system and helium source are properly installed.

2. Check and repair or replace the pressure gauge.

3. Check and repair or replace the.vacuum drying system.

4. Check and repair or replace the helium source.

Applicability: This specification is applicable to 61BT, 32PT, 24PHB, 24PTH, 61BTH and 32PTH1 DSC only.

Objective: To ensure that: (1) the atmosphere surrounding the irradiated fuel is a non-oxidizing inert gas; (2) the atmosphere is favorable for the transfer of decay heat.

Action: If the required pressure cannot be obtained:

1. Confirm that the vacuum drying system and helium source are properly installed.

2. Check and repair or replace the pressure gauge.

3. Check and repair or replace the vacuum drying system.

4. Check and repair or replace the helium source.

5. Check and repair the seal weld between the inner top cover and the DSC shell.

1.2.4 24P and 52B DSC Helium Leak Rate of Inner Seal Weld Limit/Specification:

<1.0 x 10_4 atm

• cubic centimeters per second (atm

• cm 3/s) at the highest DSC limiting pressure.

Applicability: This specification is applicable to the inner top cover seal weld, including the vent andsiphon port covers, of the 24P and 52B DSCs only.

Objective: 1. To limit the total radioactive gases normally released by each canister to negligible levels. Should fission gases escape the fuel cladding, they will remain confined by the DSC confinement boundary.

2. To retain helium cover gases within the DSC and prevent oxygen from entering the DSC. The helium improves the heat dissipation characteristics of the DSC and prevents any oxidation of fuel cladding.

Action: If the leak rate test of the inner seal weld exceeds 1.Oxl0- 4 (atm *cm 3/s):

1. Check and repair the DSC drain and fill port fittings for leaks.

2. Check and repair the inner seal weld.

3. Check and repair the inner top cover for any surface indications resulting in leakage.

Surveillance: After the welding operation has been completed, perform a leak test with a helium leak detection device.

Bases: If the DSC leaked at the maximum acceptable rate of 1.Ox10- 4 atm _ cm 3/s for a period of 20 years, about 63,100 cc of helium would escape from the DSC. This is about 1% of the 6.3 x 106 cm 3 of helium initially introduced in the DSC. This amount of leakage would have a negligible effect on the inert environment of the DSC cavity. (

American National Standards Institute, ANSI N 14.5-1987, For Radioactive Materials-Leakage Tests on Packages for Shipment," Appendix B3).

A-117

1.2.4a 61BT, 32PT, 24PHB, 24PTH, 61BTH and 32PTH1 DSC Helium Leak Rate of Inner Seal Weld Limit/Specification:

_<1.0 x 10-7 reference cubic centimeters per second (cc/s).

Applicability: This specification is applicable to the inner top cover seal weld (including vent andsiphon port cover) of 61 BT, 32PT, 24PHB, 24PTH, 61BTH and 32PTH1 DSC only.

Objective: 1. To demonstrate that the top cover to be "leak tight", as defined in "American National Standard for Leakage Tests on Packages for Shipment of Radioactive Materials," ANSI N14.5 - 1997.

2. To retain helium cover gases within the DSC and prevent oxygen from entering the DSC. The helium improves the heat dissipation characteristics of the DSC and prevents any oxidation of fuel cladding.

Action: If the leak rate test of the inner seal weld exceeds I.OxlO0- 7 reference cc/s:

1. Check and repair the inner seal weld.

2. Check and repair the inner top cover for any surface indications resulting in leakage.

Surveillance: After the welding operation has been completed, perform a leak test with a helium leak detection device.

Bases: The 61BT, 32PT, 24PHB, 24PTH, 61BTH and 32PTH1 DSC will maintain an inert atmosphere around the fuel and radiological consequences will be negligible, since it is designed and tested to be leak tight.

A-118

1.2.5 DSC Dye Penetrant Test of Closure Welds Limit/Specification:

All DSC closure welds except those subjected to full volumetric inspection shall be dye penetrant tested in accordance with the requirements of the ASME Boiler and Pressure Vessel Code Section III, Division 1, Article NB-5000. The liquid penetrant test acceptance standards shall be those described in Subsection NB-5350 of the Code.

Applicability: This is applicable to all DSCs. The welds include inner and outer top and bottom covers, and vent and siphon port covers.

Objective: To ensure that the DSC is adequately sealed in a redundant manner and leak tight.

Action: If the liquid penetrant test indicates that the weld is unacceptable:

1. The weld shall be repaired in accordance with approved ASME procedures.

2. The new weld shall be re-examined in accordance with this specification.

Surveillance: During DSC closure operations. No additional surveillance is required for this operation.

Bases: Article NB-5000 Examination, ASME Boiler and Pressure Vessel Code, Section 1II, Division 1, Sub-Section NB.

1.2.6 Deleted A-120

1.2.7 HSM Dose Rates with a Loaded 24P, 52B or 61BT DSC Limit/Specification:

Dose rates at the following locations shall be limited to levels which are less than or equal to:

a. 400 mrem/hr at 3 feet from the HSM surface.

b. Outside of HSM door on center line of DSC 100 mrem/hr.

c. End shield wall exterior 20 mrem/hr.

Applicability: This specification is applicable to all HSMs which contain a loaded 24P, 52B or 61BT DSC.

Objective: The dose rate is limited to this value to ensure that the cask (DSC) has not been inadvertently loaded with fuel not meeting the specifications in Section 1.2.1 and to maintain dose rates as-low-as-is-reasonably achievable (ALARA) at locations on the HSMs where surveillance is performed, and to reduce off-site exposures during storage.

Action: a. If specified dose rates are exceeded, the following actions should be taken:

1.2.8 HSM Maximum Air Exit Temperature with a Loaded 24P, 52B, 61BT, 32PT, 24PHB, 24PTH-S-LC or a Type 1 61BTHDSC Only Limit/Specification:

Following initial DSC transfer to the HSM or the occurrence of accident conditions, the equilibrium air temperature difference between ambient temperature and the vent outlet temperature shall not exceed 100°F when fully loaded with 24 kW heat.

Applicability: This specification is applicable to all HSMs stored in the ISFSI. If a DSC is placed in the HSM with a heat load less than 24 kW, the limiting difference between outlet and ambient temperatures shall be determined by a calculation performed by the user using the same methodology and inputs documents in the FSAR and SER.

Objective: The objective of this limit is to ensure that the temperatures of the fuel cladding and the HSM concrete do not exceed the temperatures calculated in Section 8 of the FSAR. That section shows that if the air outlet temperature difference is less than or equal to I 00°F (with a thermal heat load of 24 kW), the fuel cladding and concrete will be below the respective temperature limits for normal long-term operation.

Action: If the temperature rise is greater than that specified, then the air inlets and exits should be checked for blockage. If the blockage is cleared and the temperature is still greater than that specified, the DSC and HSM cavity may be inspected using video equipment or other suitable means. If environmental factors can be ruled out as the cause of excessive temperatures, then the fuel bundles are producing heat at a rate higher than the upper limit specified in the Specification of Section 1.2.1 and will require additional measurements and analysis to assess the actual performance of the system. If excessive temperatures cause the system to perform in an unacceptable manner and/or the temperatures cannot be controlled to acceptable limits, then the cask shall be unloaded within the time period as determined by the analysis.

Surveillance: The temperature rise shall be measured and recorded daily following DSC insertion until equilibrium temperature is reached, 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after insertion, and again on a daily basis after insertion into the HSM or following the occurrence of accident conditions. If the temperature rise is within the specifications or the calculated value for a heat load less than 24 kW, then the HSM and DSC are performing as designed to meet this specification and no further maximum air exit temperature measurements are required.

Air temperatures must be measured in such a manner as to obtain representative values of inlet and outlet air temperatures.

Basis: The specified temperature rise is selected to ensure the fuel clad and concrete temperatures are maintained at or below acceptable long-term storage limits.

A-129

1.2.8a HSM-H Maximum Air Exit Temperature with a Loaded 24PTH DSC Limit/Specification:

Applicability: This specification is applicable to all HSM-H modules stored in the ISFSI.

If a DSC is placed in the HSM-H with a heat load less than 40.8 kW, the limiting difference between outlet and ambient temperatures shall be determined by a calculation performed by the user using the same methodology and inputs documents in Appendix P of the FSAR.

Objective: The objective of this limit is to ensure that the temperatures of the fuel cladding and the HSM-H concrete do not exceed the temperatures calculated in Appendix P of the FSAR. That section shows that if the air outlet temperature difference is less than or equal to I 00°F with a thermal heat load of 40.8 kW for 24PTH-S or 24PTH-L DSC (or 70'F with a thermal heat load of 24.0 kW for 24PTH-S-LC), the fuel cladding and concrete will be below the respective temperature limits for normal long-term operation.

Action: If the temperature rise is greater than that specified, then the air inlets and exits should be checked for blockage. If the blockage is cleared and the temperature is still greater than that specified, the DSC and HSM-H cavity may be inspected using video equipment or other suitable means. If environmental factors can be ruled out as the cause of excessive temperatures, then the fuel bundles are producing heat at a rate higher than the upper limit specified in the specification of Section 1.2.1 and will require additional measurements and analysis to assess the actual performance of the system. If excessive temperatures cause the system to perform in an unacceptable manner and/or the temperatures cannot be controlled to acceptable limits, then the cask shall be unloaded within the time period as determined by the analysis.

Surveillance: The temperature rise shall be measured and recorded daily following DSC insertion until equilibrium temperature is reached, 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after insertion, and again on a daily basis after insertion into the HSM-H or following the occurrence of accident conditions. If the temperature rise is within the specifications or the calculated value for a heat load less than 40.8 kW for 24PTH-S or 24PTH-L DSC (or 24.0 kW for 24PTH-S-LC DSC) then the HSM-H and DSC are performing as designed to meet this specification and no further maximum air exit temperature measurements are required.

Air temperatures must be measured in such a manner as to obtain representative values of inlet and outlet air temperatures.

Basis: The specified temperature rise is selected to ensure the fuel clad and concrete temperatures are maintained at or below acceptable long-term storage limits.

The cask must be aligned with respect to the HSM or HSM-H that the longitudinal centerline of the DSC in the transfer cask is within +/-1/8 inch of its true position when the cask is docked with the HSM front access opening.

Applicability: This specification is applicable during the insertion and retrieval of all DSCs.

Objective: To ensure smooth transfer of the DSC from the transfer cask to HSM or HSM-H and back.

Action: If the alignment tolerance is exceeded, the following actions should be taken:

a. Confirm that the transfer system is properly configured.

b. Check and repair the alignment equipment.

c. Confirm the locations of the alignment targets on the transfer cask and HSM or HSM-H.

Surveillance: Before initiating DSC insertion or retrieval, confirm the alignment.

Observe the transfer system during DSC insertion or retrieval to ensure that motion or excessive vibration does not occur.

Basis: The basis for the true position alignment tolerance is the clearance between the DSC shell, the transfer cask cavity, the HSM or HSM-H access opening, and the DSC support rails inside the HSM or HSM-H.

A-134

1.2.10 TC/DSC Handling Height Outside the Spent Fuel Pool Building Limit/Specification: 1. When handling a loaded TC/DSC at a height greater than 80 inches outside the spent fuel pool building, a special lifting device that has at least twice the normal stress design factor for handling heavy loads, or a single failure proof handling system shall be used.

2. In the event of a drop of a loaded TC/DSC from a height greater than 15 inches: (a) fuel in the DSC shall be returned to the reactor spent fuel pool; (b) the DSC shall be removed from service and evaluated for further use; and (c) the TC shall be inspected for damage and evaluated for further use.

Applicability: The specification applies to handling the TC, loaded with the DSC, on route to, and at, the storage pad.

Objective: 1. To preclude a loaded TC/DSC drop from a height greater than 80 inches.

2. To maintain spent fuel integrity, according to the spent fuel specification for storage, continued confinement integrity, and DSC functional capability, after a tip-over or drop of a loaded DSC from a height greater than 15 inches.

Surveillance: In the event of a loaded TC/DSC drop accident, the system will be returned to the reactor fuel handling building, where, after the fuel has been returned to the spent fuel pool, the DSC and TC will be inspected and evaluated for future use.

Basis: The NRC evaluation of the TC/DSC drop analysis concurred that drops up to 80 inches, of the DSC inside the TC, can be sustained without breaching the confinement boundary, preventing removal of spent fuel assemblies, or causing a criticality accident. This specification ensures that handling height limits will not be exceeded in transit to, or at the storage pad. Acceptable damage may occur to the TC, DSC, and the fuel stored in the DSC, for drops of height greater than 15 inches. The specification requiring inspection of the DSC and fuel following a drop of 15 inches or greater ensures that the spent fuel will continue to meet the requirements for storage, the DSC will continue to provide confinement, and the TC will continue to provide its design functions of DSC transfer and shielding.

Applicability: This specification is applicable to all DSCs.

Objective: To ensure that release of non-fixed contamination above accepted limits does not occur.

Action:If the required limits are not met:

a. Flush the DSC/transfer cask annulus with demineralized water and/or scrub it using long handled tools. Repeat surface contamination surveys of the DSC upper surface.

b. If contamination of the DSC cannot be reduced to an acceptable level by this means, direct surface cleaning techniques shall be used following removal of the fuel assemblies from the DSC and removal of the DSC from the transfer cask.

1.2.13 TC/DSC Lifting Heights as a Function of Low Temperature and Location Limit/Specification: 1. No lifts or handling of the TC/DSC at any height are permissible at DSC basket temperatures below -20'F inside the spent fuel pool building.

2. The maximum lift height of the TC/DSC shall be 80 inches if the basket temperature is below 0°F but higher than -20'F inside the spent fuel pool building.

3. No lift height restriction is imposed on the TC/DSC if the basket temperature is higher than 0°F inside the spent fuel pool building.

4. When handling a loaded TC/DSC at a height greater than 80 inches outside the spent fuel pool building, a special lifting device that has at least twice the normal stress design factor for handling heavy loads, or a single failure proof handling system shall be used and the basket temperature may not be lower than 07F.

Applicability: These temperature and height limits apply to lifting and transfer of all loaded TC/DSCs inside and outside the spent fuel pool building.

The requirements of 10 CFR Part 72 apply outside the spent fuel building.

The requirements of 10 CFR Part 50 apply inside the spent fuel pool building.

Objective: The low temperature and height limits are imposed to ensure that brittle fracture of the ferritic steels, used in the TC trunnions and shell and in the DSC basket, does not occur during transfer operations.

Action: Confirm the basket temperature before transfer of the TC. If calculation or measurement of this value is unavailable, then the ambient temperature may conservatively be used.

Surveillance: The ambient temperature shall be measured before transfer of the TC/DSC.

Bases: The basis for the low temperature and height limits is ANSI N14.6-1986 paragraph 4.2.6 which requires at least 40'F higher service temperature than nil ductility transition (NDT) temperature for the TC. In the case of the standardized TC, the test temperature is -40'F; therefore, although the NDT temperature is not determined, the material will have the required 407F margin if the ambient temperature is 0°F or higher. This assumes the material service temperature is equal to the ambient temperature.

The basis for the low temperature limit for the DSC is NUREG/CR-1815.

The basis for the handling height limits is the NRC evaluation of the structural integrity of the DSC to drop heights of 80 inches and less.

A-159a

1.3 Surveillance and Monitoring One of the two alternate surveillance activities listed below (1.3.1 or 1.3.2) shall be performed for monitoring the HSM or HSM-H thermal performance.

1.3.1 Visual Inspection of HSM or HSM-H Air Inlets and Outlets (Front Wall and Roof Birdscreen)

Limit/Surveillance:

A visual surveillance of the exterior of the air inlets and outlets shall be conducted daily. In addition, a close-up inspection shall be performed to ensure that no materials accumulate between the modules to block the air flow.

Objective: To ensure that HSM or HSM-H air inlets and outlets are not blocked for more than analyzed time periodto prevent exceeding the allowable HSM or HSM-H concrete and or the fuel cladding temperatures.

Applicability: This specification is applicable to all HSMs or HSM-Hs loaded with a DSC loaded with spent fuel.

Action: If the surveillance shows blockage of air vents (inlets or outlets), they shall be cleared. If the screen is damaged, it shall be replaced.

Basis: The concrete temperature could exceed 350'F in the accident circumstances of complete blockage of all vents. Concrete temperatures over 350'F in accidents (without the presence of water or steam) can have uncertain impact on concrete strength and durability. A conservative analysis (adiabatic heat case) of complete blockage of all air inlets or outlets indicates that the concrete can reach the accident temperature limit of 350'F in the time periods specified for HSM. For HSM-H, the time period specified ensures that blockage will not exist for periods longer than that assumed in the Safety analysis presented in Appendix P, Appendix T andAppendix U of the FSAR. At the analyzed time limit, the fuel cladding temperature remains well below the accident limit of 1058'F.

A-160

1.3.2 HSM or HSM-H Thermal Performance Surveillance: Verify a temperature measurement of the thermal performance, for each HSM or HSM-H, on a daily basis. The temperature measurement could be any parameter such as (1) a direct measurement of the HSM or HSM-H temperatures, (2) a direct measurement of the DSC temperatures, (3) a comparison of the inlet and outlet temperature difference to predicted temperature differences for each individual HSM or HSM-H, or (4) other means that would identify and allow for the correction of off-normal thermal conditions that could lead to exceeding the concrete and fuel clad temperature criteria. If air temperatures are measured, they must be measured in such a manner as to obtain representative values of inlet and outlet air temperatures. Also due to the proximity of adjacent HSM or HSM-H modules, care must be exercised to ensure that measured air temperatures reflect only the thermal performance of an individual module, and not the combined performance of adjacent modules.

Action: If the temperature measurement shows a significant unexplained difference, so as to indicate the approach of materials to the concrete or fuel clad temperature criteria, take appropriate action to determine the cause and return the canister to normal operation. If the measurement or other evidence suggests that the concrete accident temperature criteria (350'F) has been exceeded for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, the HSM or HSM-H must be removed from service unless the licensee can provide test results in accordance with ACI-349, appendix A.4.3, demonstrating that the structural strength of the HSM or HSM-H has an adequate margin of safety.

Basis: The temperature measurement should be of sufficient scope to provide the licensee with a positive means to identify conditions which threaten to approach temperature criteria for proper HSM or HSM-H operation and allow for the correction of off-normal thermal conditions that could lend to exceeding the concrete and fuel clad temperature criteria.
