SUMMARY OF FINDINGS

IR 05000263/2011009, 03/23/2011

- 04/29/2011; Monticello Nuclear Generating Plant Temporary Instruction 2515/183

- Followup to the Fukushima Daiichi Nuclear Station Fuel Damage Event.

This report covers an announced Temporary Instruction (TI) inspection. The inspection was conducted by Resident and Region III inspectors. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG

-1649, "Reactor Oversight Process," Revision 4, dated December 2006

.

INSPECTION SCOPE

The intent of the TI is to provide a broad overview of the industry's preparedness for events that may exceed the current design basis for a plant.

The focus of the TI was on

(1) assessing the licensee's capability to mitigate consequences from large fires or explosions on site, (2)assessing the licensee's capability to mitigate station blackout (SBO) conditions,
(3) assessing the licensee's capability to mitigate internal and external flooding events accounted for by the station's design, and
(4) assessing the thoroughness of the licensee's walk downs and inspections of important equipment needed to mitigate fire and flood events to identify the potential that the equipment's function could be lost during seismic events possible for the site.

If necessary, a more specific follow

-up inspection will be performed at a later date.

INSPECTION RESULTS

All of the potential issues and observations identified by this inspection are contained in this report. The NRC's Reactor Oversight Process will further evaluate any issues to determine if they are regulatory findings or violations.

Any resulting findings or violations will be documented by the NRC in the next quarterly report.

03.01 Assess the licensee's capability to mitigate conditions that result from beyond design basis events, typically bounded by security threats, committed to as part of NRC Security Order Section B.5.b issued February 25, 2002, and severe accident management guidelines as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.54 (hh). Use Inspection Procedure (IP) 71111.05T, "Fire Protection (Triennial)," Section 02.03 and 03.03 as a guideline.

If IP 71111.05T was recently performed at the facility , the inspector should review the inspection results and findings to identify any other potential areas of inspection.

Particular emphasis should be placed on strategies related to the spent fuel pool.

The inspection should include, but not be limited to, an assessment of any licensee actions to:

Licensee Action Describe what the licensee did to test or inspect equipment.

a. Verify through test or inspection that equipment is available and functional. Active equipment shall be tested and passive equipment shall be walked down and inspected.

It is not expected that permanently installed equipment that is tested under an existing regulatory testing program be retested.

This review should be done for a reasonable sample of mitigating strategies/equipment.

The licensee performed walkdowns with qualified operators and discussions took place regarding the use of the procedures an d the desired result

, as well as the required equipment. Equipment inventories were completed using approved site procedures with all gaps noted in the corrective action process. Monticello has the capability to mitigate conditions that result from beyond basis events, typically bounded by security threats, committed to as part of B.5.b licensing process and using severe accident management guidelines. The flooding events require materials not currently onsite, but the procedure is written assuming the flooding can be predicted allowing for the material to be obtained and barriers constructed.

The following procedures were performed to verify equipment was available and functional:

1488; Emergency Operating Procedures (EOP)/Abnormal Operating Procedures (AOP) Equipment Inventory; 1224; Fire Brigade Equipment Inventory; OSP-FIR-0582; Portable Diesel Fire Pump Testing Procedure; ESP-125-0583; 125V DC Portable Battery Cart Testing Procedure; and IMP-1023; Fluke Model 87V EX Digital Multimeter Performance Test.

Procedure 1224 requires that the operator perform a condition inspection using criteria outlined in the procedure. Active equipment, such as the portable diesel fire pump and 125 VDC battery cart

, were tested using approved site procedures. The 1488 procedure does not specifically require that an inspection be performed during the equipment inventory. Nonetheless, the inventory done for this activity did assess the condition and readiness of the equipment. All Emergency Operating Procedure (EOP) equipment was validated to be stored in the proper location.

Describe inspector actions taken to confirm equipment readiness (e.g., observed a test, reviewed test results, discussed actions, reviewed records, etc.).

The inspectors assessed the licensee's capabilities by conducting a review of the licensee's walkdown activities. In addition, the inspectors independently walked down and inspected a sampling of the major B.5.b contingency equipment staged throughout the plant

. Discuss general results including corrective actions by licensee.

During the EOP inventory, equipment was found to be stored in areas that could potentially be susceptible to damage during a seismic event. While performing the fire brigade inventory (1224), some equipment was not in the proper storage location

, and some equipment called out in the B.5.b procedures was not on the inventory as expected. Corrective actions were documented to correct these issues. The missing equipment f rom the B.5.b procedures is readily available at numerous locations onsite

however , a dedicated supply was not in the dedicated B.5.b storage location.

Specific corrective action program (CAP) documents applicable to this section are listed in Section 3.01(e).

No issues of significance were identified by the inspectors.

Licensee Action Describe the licensee's actions to verify that procedures are in place and can be executed (e.g.

, walkdowns, demonstrations, tests, etc.)

. b. Verify through walkdowns or demonstration that procedures to implement the strategies associated with B.5.b and

10 CFR 50.54

(hh) are in

-place and are executable. Licensees may choose not to connect or operate permanently installed equipment during this verification.

This review should be done for a reasonable sample of mitigating strategies/equipment.

The A.7 - Severe Accident Mitigation Guidelines (SAMG) procedures are in

-place and executable. This was demonstrated by a tabletop exercise using an Accident Management Team (AMT) stationed in the Technical Support Center (TSC) with an operator in the control room simulator to demonstrate the communication link. The tabletop exercise challenged all legs of the SAMGs. Activities to be performed in the plant were done by operations personnel in a walk

-through format with an evaluator observing their performance. The AMT was able to complete priority actions that would have ensured event mitigation.

The SAMG s refer to multiple EOP Support Procedures (C.5

-3 XXX) that are part of the regular training cycle for the Operations crews. All actions performed by Operations during SAMG situations are in the EOP Support Procedures. Several of the A.8 (Extensi ve Damage Mitigation Strategy (EDMG) Overview) procedures that implement the B.5.b program requirements are in

-place and validated as executable via walkdowns.

Describe inspector actions and the sample strategies reviewed. Assess whether procedures were in place and could be used as intended.

The inspectors assessed the licensee's capabilities by conducting a review of the licensee's walkdown activities. In addition, the inspectors selected several sections of a sample of the procedures walked down by the licensee and walked them down to independently verify the licensee's conclusions.

The inspectors did not observe the performance of the tabletop exercise, but did review the exercise materials.

Discuss general results including corrective actions by licensee.

No gaps were identified that would impair the station's ability to utilize these mitigation strategies.

Several enhancement opportunities were documented and entered in the licensee's corrective action process.

Specific CAP documents applicable to this section are listed in Section 3.01(e)

.

No issues of significance were identified by the inspectors.

Licensee Action Describe the licensee's actions and conclusions regarding training and qualifications of operators and support staff.

c. Verify the training and qualifications of operators and the support staff needed to implement the procedures and work instructions are current for activities related to Security Order Section B.5.b and severe accident management guidelines as required by 1 0 CFR 50.54 (hh).

The licensee conducted a review of their Emergency Plan (EP) Training Program, as well as a qualification search for the number of individuals qualified in each position

, via the Learning Management System (LMS) tool. The Training Department verified that all positions in the six ERO duty teams were staffed by individuals qualified in their associated jobs. Describe inspector actions and the sample strategies reviewed to assess training and qualifications of operators and support staff The inspectors assessed the licensee's training and qualification activities by conducting a review of training and qualification materials and records related to the current Emergency Response Organization (ERO) qualifications of the assigned site staff.

Discuss general results including corrective actions by licensee.

The training requirements, qualifications, and associated records needed to verify that the site's ERO could be staffed and function during an event , were reviewed by the licensee. This recommendation is being met in accordance with site procedures and regulatory commitments. No deficiencies were noted when applicable training and qualification documents were reviewed.

Specific CAP documents applicable to this section are listed in Section 3.01(e). No issues of significance were identified by the inspectors.

Licensee Action Describe the licensee's actions and conclusions regarding applicable agreements and contracts are in place. d. Verify that any applicable agreements and contracts are in place and are capable of meeting the conditions needed to mitigate the consequences of these events.

This review should be done for a reasonable sample of mitigating strategies/equipment.

The licensee performed a review of B.5.b and SAMG procedures to determine what equipment is required from offsite venders to successfully implement their procedures. The review was also expanded to include flooding and SBO concerns to consolidate the scope and content of the agreements/contracts. The licensee conducted interviews of site program owners to determine what contracts were in place and what services, equipment, or materials offsite entities had agreed to provid e. For a sample of mitigating strategies involving contracts or agreements with offsite entities, describe inspector actions to confirm agreements and contracts are in place and current (e.g., confirm that offsite fire assistance agreement is in place and current). The inspectors assessed the licensee's capabilities by conducting an independent review of the licensee's letters of agreement, memorandums of understanding, and contracts for goods and services counted on to successfully implement their SAMGs and EDMGs. The inspectors verified that each was current and whether or not each was adequate for meeting the licensee's mitigation strategy.

Discuss general results including corrective actions by licensee.

Gaps were identified during the licensee's review of offsite equipment that might be necessary to effectively implement their mitigating strategies. Corrective action documents have been initiated for the site to determine what equipment should be available onsite and what agreements are adequate for equipment that comes from offsite sources. At this time, the site has not made formal agreements to provide all equipment required from offsite entities. The licensee has determined that the agreements that are currently in place are sufficient to provide resources that the site might request in the event to allow for effective utilization of their mitigation strategies.

Further review is required to determine what equipment should be purchased for onsite storage and what formal agreements should be made with offsite suppliers.

Specific CAP documents applicable to this section are listed in Section 3.01(e).

No issues of significance were identified by the inspectors

.

Licensee Action Document the corrective action report number and briefly summarize problems noted by the licensee that have significant potential to prevent the success of any existing mitigating strategy.

e. Review any open corrective action documents to assess problems with mitigating strategy implementation identified by the licensee. Assess the impact of the problem on the mitigating capability and the remaining capability that is not impacted.

Items that were identified by the licensee and entered into their CAP to address issues identified during the evaluation of IER 11

-1 , Recommendation 2

, are listed in the List of Documents Reviewed at the end of this report.

No issues of significance were identified by the inspectors.

03.03 Assess the licensee's capability to mitigate internal and external flooding events required by station design. Refer to IP 71111.01, "Adverse Weather Protection," Section 02.04, "Evaluate Readiness to Cope with External Flooding

," as a guideline. The inspection should include, but not be limited to, an assessment of any licensee actions to verify through walkdowns and inspections that all required materials and equipment are adequate and properly staged.

These walkdowns and inspections shall include verification that accessible doors, barriers, and penetration seals are functional.

Licensee Action Describe the licensee's actions to verify the capability to mitigate existing design basis flooding events.

a. Verify through walkdowns and inspection that all required materials are adequate and properly staged, tested, and maintained.

The structures, systems, and components (SSCs) credited in MNGP's External Flooding, Internal Flooding, and High Energy Line Break (HELB) programs were cataloged. This catalogue list included all SSCs which control the movement of water between adjacent volumes and the boundary penetrations between these adjacent volumes. Only the penetrations at or below maximum probable water levels based on station flooding calculations were evaluated.

Utilizing this list, field walkdowns were conducted to assess the condition of the flood control SSCs. For external flooding, a walkdown was performed to ensure pathways were clear and capable of performing their function (i.e.

, passage of water along the path assumed in the applicable calculation).

The acceptability of the flood barriers and relief paths was documented on the list of the flood control SSCs. Describe inspector actions to verify equipment is available and useable. Assess whether procedures were in place and could be used as intended.

The inspectors assessed the licensee's capabilities to mitigate flooding by conducting a review of the licensee's walkdown activities. Flood mitigation procedures were reviewed to verify usability. In addition, the inspectors conducted independent walkdowns of selected flood mitigation equipment to independently assess the licensee's flood mitigation capabilities.

Discuss general results including corrective actions by licensee.

Of the 377 components to be inspected, 39 were not accessible. Monticello Nuclear Generating Plant is currently in a Refueling Outage (RFO). Currently during the refueling outage, work at the plant has required partial disassembly of credited barriers

, created temporary openings through boundaries

, restricted access to protected equipment

, and obstructed viewing of some equipment by scaffold or other non

-permanent tools and equipment staged for work. These items will be tracked as follow-on actions, with walkdowns to be conducted when station conditions permit. A walkdown was performed of the accessible plant areas having flood barriers and required relief paths. Walkdown notes documented the acceptability of every SSC and the cases where SSCs were inaccessible and could not be inspected.

Items that were identified by the licensee and entered into their CAP to address issues identified during the evaluation of IER 11

-1 , Recommendation 3

, are listed in the List of Documents Reviewed at the end of this report.

No issues of significance were identified by the inspectors.

03.04 Assess the thoroughness of the licensee's walkdowns and inspections of important equipment needed to mitigate fire and flood events to identify the potential that the equipment's function could be lost during seismic events possible for the site.

Assess the licensee's development of any new mitigating strategies for identified vulnerabilities (e.g., entered it in to the corrective action program and any immediate actions taken).

As a minimum, the licensee should have performed walkdowns and inspections of important equipment (permanent and temporary)

, such as storage tanks, plant water intake structures, and fire and flood response equipment , and developed mitigating strategies to cope with the loss of that important function. Use IP 71111.21, "Component Design Basis Inspection," Appendix 3, "Component Walkdown Considerations," as a guideline to assess the thoroughness of the licensee's walkdowns and inspections.

Licensee Action Describe the licensee's actions to assess the potential impact of seismic events on the availability of equipment used in fire and flooding mitigation strategies.

a. Verify through walkdowns that all required materials are adequate and properly staged, tested, and maintained.

Important SSCs for fire protection were determined as equipment that can mitigate post safe-shutdown earthquake (SSE) fires in the following four categories: permanently installed fire protection systems; permanently installed, seismically-qualified non-fire protection systems that could be used to fight fires; portable equipment that could be used to fight fires after a n SSE; and offsite responders.

These categories of equipment , individually or in aggregate, must be capable of fighting fires in the critical portions of the station. Examples of critical portions of the station could include: control room and support structures; electrical switchgear rooms; turbine building; reactor building; diesel generator buildings; main and auxiliary transformers; and intake structures.

Piping and instrumentation diagrams were used to define the boundaries of the fire protection system within the scope of this recommendation

, and the flood protection SSCs for this recommendation are the same as those used for Recommendation 3.

The licensee enlisted a contractor

, wh o specializes in the evaluation of the impacts of seismic activity on structures

, to perform walkdowns of specific areas onsite. Working from the lists of fire protection and flood protection SSCs provided by the licensee, this contractor performed a walkdown and examine d all of the flood and fire mitigation SSCs which were identified

, and assess ed the seismic vulnerability of these SSCs as high, medium, or low. A low vulnerability meant that the SSC would clearly withstand the SSE for the Monticello site. A medium vulnerability mean t it was highly likely that the component would be shown through analysis to be able to survive the SSE for Monticello. A high vulnerability mean t that it was quite possible that an SSE would disable the component.

Describe inspector actions to verify equipment is available and useable. Assess whether procedures were in place and could be used as intended.

The inspectors conducted multiple walkdowns of important equipment needed to mitigate fire and flood events to identify the potential that the equipment's function could be lost during or subsequent to a seismic event. Specific equipment reviewed as part of this assessment included a sampling of the major B.5.b contingency response equipment

, installed fire protection and suppression equipment

, installed diesel and electric fire pumps

, and watertight hatches and floor plugs. In addition to the walkdowns, the inspectors reviewed a report prepared by the contractor which documented the results of how site flood and fire mitigation equipment would be impacted by an SSE. Discuss general results including corrective actions by licensee. Briefly summarize any new mitigating strategies identified by the licensee as a result of their reviews.

For fire protection, the overall conclusion was that the system would likely suffer key failures in an SSE and could not be relied upon to be available after an earthquake. The mitigation strategy is to use B.5.b equipment to fight any fires that would occur following an earthquake. The B.5.b equipment is stored in a warehouse that is not designed as a Seismic Class I structure, but was examined by seismic experts and was it was concluded that it would remain intact following a n SSE. Items that were identified by the licensee and entered into their CAP to address issues identified during the evaluation of IER 11

-1 , Recommendation 4

, are listed in the List of Documents Reviewed at the end of this report.

No issues of significance were identified by the inspectors.
