SUBJECT: MILLSTONE POWER STATION - NRC TRIENNIAL FIRE PROTECTION INSPECTION REPORT 05000336/2016007 AND 05000423/2016007

Dear Mr. Heacock:

On August 11, 2016, the U.S. Nuclear Regulatory Commission (NRC) completed a triennial fire

protection inspection at Millstone Power Station, Units 2 and 3. The enclosed inspection report documents the inspection results, which were discussed on August 11, 2016, with Mr. John Daugherty, Site Vice President - Millstone Power Station, and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations, and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed station personnel. The inspectors also reviewed mitigation strategies for addressing large fires and explosions.

Based on the results of this inspection, one finding of very low safety significance (Green) was

identified. This finding was determined to be a violation of NRC requirements. However, because of its very low safety significance, and because it was entered into your corrective action program, the NRC is treating this finding as a non-cited violation (NCV) consistent with

Section 2.3.2 of the NRC Enforcement Policy. If you contest any NCV in this report, you should

provide a written response within 30 days of the date of this inspection report, with the basis for

your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington D.C. 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement; and the NRC Resident Inspector at Millstone Power Stations.

D. Heacock 2

In accordance with Title 10 of the Code of Federal Regulations

(10 CFR) 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be

available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of the NRC's document system, Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible

ii SUMMARY OF FINDINGS

IR 05000336/2016007, 05000423/2016007; 07/25/2016 - 08/11/2016; Dominion Nuclear

Connecticut, Inc.; Millstone Power Station, Units 2 and 3; Fire Protection (Triennial).

This report covered a two week on-site triennial fire protection team inspection by specialist inspectors. One finding of very low safety significance was identified. This finding was determined to be a non-cited violation. The significance of most findings is indicated by their

color (Green, While, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process." The cross-cutting aspects associated with findings were determined

using IMC 0310, "Components Within The Cross-Cutting Areas." Findings for which the

significance determination process (SDP) does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 6, dated July 2016.

Cornerstone: Mitigating Systems

Green. The team identified a finding of very low safety significance (Green) involving a non-cited violation of Millstone Power Station, Unit 2, Renewed Facility Operating License Condition 2.C.(3) to implement and maintain in effect all provisions of the approved fire

protection program as described in the Final Safety Analysis Report (FSAR). Specifically, Dominion failed to maintain the #2 steam generator (SG) atmospheric dump valve (ADV)

free from fire damage, which may have affected the availability to maintain hot shutdown

conditions from the main control room for a fire in Fire Area R-14, Lower 4.16kV Switchgear Room and Cable Vault.

Dominion promptly entered this safe shutdown issue into their corrective action program as condition report (CR) 1043458. Immediate corrective actions included implementing compensatory measures in the form of fire watches for fire area R-14

that are being tracked by Reasonable Assurance of Safety (RAS) determination 3037040.

Longer term corrective actions included submitting an exemption request to the NRC for use of a local operator manual action (OMA) to operate the #2 SG ADV in lieu of meeting fire protection requirements for fire area R-14. The team considered Dominion's immediate and

longer term corrective actions appropriate.

The performance deficiency was more than minor because it affected the Mitigating

Systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to an external event to prevent undesirable consequences in the event of a fire. Specifically, the use of an OMA during post-fire safe shutdown is not as reliable as normal

systems operation which could be utilized had the requirements of 10 CFR Part 50,

Appendix R,Section III.G.2 been met and, therefore, prevented fire damage to credited

components and/or cables, specifically the #2 SG ADV. The inspectors used IMC 0609, Appendix F, Fire Protection Significance Determination Process, Phase 1 and determined the reactor is able to reach and maintain a hot safe shutdown condition because the SG

ADVs are used for transition to cold shutdown, therefore this finding was of very low safety significance (Green). This finding does not have a cross cutting aspect because the

performance deficiency occurred greater than three years ago when the June 30, 2011

exemption request letter to the NRC was supplemented by letter on February 29, 2012, and is not indicative of current licensee performance. (Section 1R05.01)

iii Other Findings

Three violations of very low safety significance that were identified by Dominion were reviewed by the team. Corrective actions taken or planned by Dominion have been entered into

Dominion's corrective action program (CAP). The violations and corrective action tracking

numbers are listed in Section 4OA7 of this report.

REPORT DETAILS

Background

This report presents the results of a triennial fire protection inspection conducted in accordance

with the U.S. Nuclear Regulatory Commission (NRC) Inspection Procedure (IP) 71111.05T,

"Fire Protection (Triennial)." The objective of the inspection was to assess whether Dominion

Nuclear Connecticut, Inc. (Dominion) has implemented an adequate fire protection program

(FPP) and that post-fire safe shutdown capabilities have been established and are being properly maintained at the Millstone Power Station Unit 2 and Unit 3 (Millstone). The following fire areas (FA) and/or fire zones (FZ) were selected for detailed review based on risk insights

from the Millstone Individual Plant Exam

ination of External Events (IPEEE).

Unit 2 Fire Areas / Fire Zones

R-7 / A-15, "A" Diesel Generator Room A R-1 / A-32, Main Ventilation Room (Air Handling Units) R-14 / T-7, 6.9 & 4.16 kV Switchgear Room R-14 / T-9, East Cable Vault

Unit 3 Fire Areas

AB-6, West MCC & Rod Control Area CB-11, Instrument Rack Room and Underfloor Area EG-3, North Emergency Generator Enclosure ESF-3, North Residual Heat Removal - Heat Exchanger Cubicle

Inspection of these areas/zones fulfills the inspection procedure requirement to inspect a

minimum of three samples.

The inspection team evaluated Dominion's FPP against applicable requirements which included

Unit 2 Renewed Facility Operating License Condition 2.C.(3), Unit 3 Renewed Facility Operating

License Conditions 2.H, NRC Safety Evaluation Reports (SERs), Title 10 of the

Code of Federal

Regulations (10 CFR) 50.48, 10 CFR Part 50, Appendix R and Branch Technical Position (BTP) Chemical Engineering Branch (CMEB) 9.5-1.

The team also reviewed related documents that included the Updated Final Safety Analysis Repor

t (UFSAR), Fire Protection Program, Fire

Hazards Analyses (FHA), and post-fire Safe Shutdown Analyses Reports.

The team also evaluated two Unit 2 and two Unit 3 licensee mitigating strategies for addressing

large fires and explosions as required by Unit 2 Renewed Facility Operating License Condition 2.C.(13), Unit 3 Renewed Facility Operating License Condition 2.C.(10), and 10 CFR 50.54 (hh)(2). Inspection of these strategies fulfills the inspection procedure requirement to inspect a minimum of one sample.

Specific documents reviewed by the team are listed in the Attachment to this report.

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity

1R05 Fire Protection (IP 71111.05T)

.01 Protection of Safe Shutdown Capabilities

a. Inspection Scope

The team reviewed the FHA, safe shutdown analyses, and supporting drawings and documentation to verify that post-fire safe shutdown capabilities were properly protected. The team ensured that applicable separation requirements of Section III.G of 10 CFR

Part 50, Appendix R for Unit 2 and BTP CMEB 9.5-1 for Unit 3 as well as the licensee's

design and licensing bases were maintained for the credited safe shutdown equipment

and their supporting power, control, and instrumentation cables. This review included an

assessment of the adequacy of the selected systems for reactivity control, reactor coolant makeup, reactor heat removal, process monitoring, and associated support system functions.

b. Findings

Introduction: The team identified a finding of very low safety significance (Green) involving a non-cited violation of Millstone Unit 2 Renewed Facility Operating License Condition 2.C.(3) to implement and maintain in effect all provisions of the approved fire

protection program as described in the FSAR. Specifically, Dominion failed to maintain

the #2 SG ADV free from fire damage, which may have affected the availability to maintain hot shutdown conditions from the main control room for a fire in Fire Area R-14, Lower 4.16kV Switchgear Room and Cable Vault.

Description: The inspectors reviewed the operator manual actions (OMAs) contained in operating procedure AOP 2579M, Fire Procedure for Hot Standby Appendix R Fire Area

R-14, and compared them against the list of NRC approved OMAs in lieu of meeting III.G.2 fire protection requirements and determined that an unapproved OMA was being implemented in AOP 2579M. The OMAs in

lieu of meeting III.G.2 fire protection requirements were approved in an NRC exemption dated December 18, 2012. The

missing OMA was an action to locally operate air-operated valve, 2-MS-190B, #2 SG

ADV. The OMA is necessary since a self-induced loss of offsite power (LOOP) will occur and station blackout (SBO) condition may occur from fire related cable damage. Either condition, LOOP or SBO, will cause a loss of instrument air in response to a

significant fire in fire area R-14.

The LOOP will occur when AOP 2579M is implemented because step 3.4 requires the

operators to trip the reactor (causing a loss of the normal station service transformer) and step 3.9 requires the operators to direct CONVEX (transmission operator) to de-energize the reserve station service transformer. A SBO may subsequently occur if the

B emergency diesel generator (EDG) is running and its output breaker does not close,

3 which could occur due to fire-related circuit damage. In either condition, LOOP or SBO, the 'F' instrument air compressor, will be de-energized and a loss of instrument air will

occur. In 2011, Dominion submitted an exemption request to the NRC for several OMAs in lieu of meeting III.G.2 fire protection requirements in several fire areas and initially postulated a loss of instrument air for Fire Area R-14. Three OMAs were requested related to the

loss of instrument air for Fire Area R-14 in a June 30, 2011 exemption request letter to

the NRC. Subsequent to the June 30, 2011 exemption request letter, Dominion walked

down several fire areas and from a mechanical perspective concluded that a loss of instrument air should no longer be postulated for several fire areas. R-14 was included as a fire area for which a loss of instrument air was no longer considered credible. In a

request for additional information response letter dated February 29, 2012, Dominion

stated that the loss of instrument air was no longer postulated in fire area R-14 and

others, and requested the NRC delete the OMA for

locally operating the #2 SG ADV. In a correction letter dated October 29, 2012, Dominion again reiterated that for Fire Area R-14, and others, a Loss of Instrument Air was not postulated, but Dominion clarified that some of the OMAs that were related to a loss of instrument air should be retained

for postulated fire cable damage or loss of power. However, the OMA for locally

operating the #2 SG ADV was not retained since it was not susceptible to cable damage

or loss of power for a fire in area R-14. Dominion stated in its June 30, 2011 exemption request letter to the NRC that after auxiliary feedwater (AFW) is established from the control room, operation of the ADV (2-MS-1 90B) is the required method of removing

decay heat to maintain hot standby and transition to cold shutdown.

As described above, the inspectors determined that implementing AOP 2579M as

written will cause a loss of instrument air and the OMA to locally operate the #2 SG ADV will be necessary after AFW is restored and decay heat removal is transitioned from the main steam safety valves to the #2 SG ADV for steam generator pressure control. The

inspectors noted that Dominion is currently implementing an unapproved OMA in lieu of

meeting III.G.2 fire protection requirements. Dominion promptly entered this safe

shutdown issue into their corrective action program as CR 1043458. Immediate corrective actions included implementing compensatory measures in the form of fire watches for fire area R-14 that are being tracked by RAS determination 3037040.

Longer term corrective actions included submitting an exemption request to the NRC for use of a local OMA to operate the #2 SG ADV in lieu of meeting fire protection

requirements for fire area R-14. The team considered Dominion's immediate and longer term corrective actions appropriate.

Analysis: Dominion's failure to protect the #2 SG ADV, credited for post-fire safe shutdown from fire damage in Fire Area R-14 caused by single spurious actuation, is

considered a performance deficiency. The performance deficiency was more than minor

because it affected the Mitigating Systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to an external event to prevent undesirable consequences in the event of a fire. Specifically, the use of an

OMA during post-fire safe shutdown may not be as reliable as normal systems operation

which could be utilized had the requirements of 10 CFR Part 50, Appendix R, Section

4 III.G.2 been met and, therefore, prevented fire damage to credited components and/or cables, specifically the #2 SG ADV.

The inspectors used IMC 0609, Appendix F, Fire Protection Significance Determination

Process, Phase 1 and determined the reactor is able to reach and maintain a hot safe shutdown condition because the ADVs are used for transition to cold shutdown, therefore this finding was of very low safety significance (Green).

This finding does not have a cross cutting aspect because the performance deficiency

occurred greater than three years ago when the June 30, 2011 exemption request letter to the NRC was supplemented by letter on February 29, 2012, and is not indicative of current licensee performance.

Enforcement: Millstone Power Station, Unit 2, Renewed Facility Operating License Condition 2.C.(3) requires Dominion in part to implement and maintain in effect all

provisions of the approved fire protection program as described in the FSAR. FSAR Section 9.10.6, Safety Shutdown Design Bases, states in part Paragraph 50.48(b) of 10 CFR 50, which became effective on February 17, 1981, that all nuclear plants licensed

to operate prior to January 1, 1979, comply with specific portions of Section III of

Appendix R to 10 CFR 50. Section III.G requires that fire protection features be

provided for those systems, structures, and components important to safe shutdown. These features must be capable of limiting fire damage so that one train of systems necessary to achieve and maintain hot shutdown conditions from either the main control

room or the emergency control stations is free of fire damage.

Contrary to the above, since February 17, 1981 (the effective date of Appendix R and

revised 10 CFR 50.48), and ongoing as of the inspection exit date, Dominion failed to implement all provisions of the approved fire protection program. Specifically, the safe shutdown strategy in Fire Area R-14 for Millstone Unit 2 relied upon an unapproved

OMA to mitigate post-fire safe shutdown equipment malfunctions caused by a single

spurious actuation, in lieu of protecting the equipment in accordance with 10 CFR Part

50 Appendix R,Section III.G.2. The specific OMA associated with Fire Area R-14 includes local manual control of the #2 SG ADV. Dominion's immediate corrective actions included implementing compensatory measure in the form of fire watches for fire area R-14. Because this violation was of very low safety significance (Green), and was

entered into Dominion's CAP (CR 1043458), this issue is being treated as an NCV

consistent with Section 2.3.2 of the Enforcement Policy.

Area R-14, Lower 4kV Switchgear Room and Cable Vault)

.02 Passive Fire Protection

a. Inspection Scope

The team walked down accessible portions of the selected fire areas to evaluate

whether the material conditions of the fire area boundaries were adequate for the fire

hazards in the area. The team compared the fire area boundaries, including walls,

ceilings, floors, fire doors, fire dampers, penetration seals, and redundant equipment fire

5 barriers to design and licensing basis requirements, industry standards, and the Millstone Power Station Unit 2 and Unit 3 FPPs, as approved by the NRC, to identify any

potential degradation or non-conformances.

The team reviewed selected engineering evaluations, installation and repair work orders, and qualification records for a sample of penetration seals to determine whether the fill material was properly installed and whether the as-left configuration satisfied design requirements for the intended fire rating.

The team also reviewed recent inspection and functional test records for fire dampers, and the inspection records for penetration seals and fire barriers, to verify whether the inspection and testing was adequately conducted, the acceptance criteria were met, and

any potential performance degradation was identified.

b. Findings

No findings were identified.

.03 Active Fire Protection

a. Inspection Scope

The team evaluated manual and automatic fire suppression and detection systems in the

selected fire areas to determine whether they were installed, tested, maintained, and

operated in accordance with NRC requirements, National Fire Protection Association

(NFPA) codes of record, and the Millstone

FPPs, as approved by the NRC. The team also assessed whether the suppression systems capabilities were adequate to control and/or extinguish fires associated with the hazards in the selected areas.

The team reviewed the as-built capability of the fire water supply system to verify the design and licensing basis and NFPA code of record requirements were satisfied, and to

assess whether those capabilities were adequate for the hazards involved. The team

reviewed the fire water system hydraulic analyses to assess the adequacy of a single fire water pump to supply the largest single hydraulic load on the fire water system plus

concurrent fire hose usage. The team evaluated the fire pump performance tests to

assess the adequacy of the test acceptance criteria for pump minimum discharge

pressure at the required flow rate, to verify the criteria was adequate to ensure that the design basis and hydraulic analysis requirements were satisfied. The team also evaluated the underground fire loop flow tests to verify the tests adequately

demonstrated that the flow distribution circuits were able to meet design basis

requirements. In addition, the team reviewed recent pump and loop flow test results to

verify the testing was adequately conducted, the acceptance criteria were met, and any

potential performance degradation was identified.

The team reviewed initial discharge testing, design specifications, vendor requirements, modifications and engineering evaluations, and routine functional testing for the CO

2 and Halon suppression systems for the areas protection. The team walked down accessible

potions of the CO

2 and Halon systems, including storage tanks and supply systems, to

6 independently assess the material condition, operational lineup, and availability of the systems. The team also reviewed and walked down the associated firefighting

strategies and CO

2 and Halon system operating procedures.

The team walked down accessible portions of the detection and water suppression systems in the selected areas and major portions of the fire water supply system, including motor and diesel driven fire

pumps, interviewed system and program engineers, and reviewed selected correct

ive action program documents (condition reports) to independently assess the material condition of the systems and components. In addition, the team reviewed recent test results for the fire detection and suppression systems for the selected fire areas to verify the testing was adequately conducted, the acceptance criteria were met, and any performance degradation was identified.

The team assessed the fire brigade capabilities by reviewing training, qualification, and

drill critique records. The team also reviewed Millstone's firefighting strategies (i.e. pre-

fire plans) and smoke removal plans for the selected fire areas to determine if appropriate information was provided to fire brigade members and plant operators to identify safe shutdown equipment and instrumentation, and to facilitate suppression of a

fire that could impact post-fire safe shutdown capability. The team independently

inspected the fire brigade equipment, including personnel protective gear (e.g. turnout

gear) and smoke removal equipment, to determine operational readiness for firefighting. In addition, the team reviewed Millstone's fire brigade equipment inventory and inspection procedure and recent inspection and inventory results to verify adequate

equipment was available, and any potential material deficiencies were identified.

b. Findings

No findings were identified.

.04 Protection from Damage from Fire Suppression Activities

a. Inspection Scope

The team walked down the selected fire areas and adjacent areas, and reviewed

selected documents to determine whether redundant safe shutdown trains could be

potentially damaged from fire suppression activi

ties or from the rupture or inadvertent operation of fire suppression systems. During the walkdowns, the team evaluated the adequacy and condition of floor drains, equipment elevations, and spray protection.

Specifically, to determine whether a potential existed to damage redundant safe shutdown trains, the team evaluated whether:

A fire in one of the selected fire areas would not release smoke, heat, or hot gases that could cause unintended activation of suppression systems in adjacent fire areas which could potentially damage all redundant safe shutdown trains; or

A fire suppression system rupture, inadvertent actuation, or actuation due to a fire, in one of the selected fire areas, could not directly damage all redundant trains (e.g. sprinkler caused flooding of other than the locally affected train); and

7 Adequate drainage was provided in areas protected by water suppression systems.

b. Findings

No findings were identified.

.05 Post-Fire Safe Shutdown Capability - Normal and Alternative

a. Inspection Scope

The team reviewed the safe shutdown analysis, thermal-hydraulic analysis, operating procedures, time critical operator action validation studies, piping and instrumentation

drawings (P&lDs), electrical drawings, the UFSAR, and other supporting documents for

the selected fire areas to verify whether Dominion had properly identified the systems

and components necessary to achieve and maintain post-fire safe shutdown conditions.

The team evaluated selected systems and co

mponents credited by the safe shutdown analysis for reactor pressure control, reactivity control, reactor coolant makeup, decay heat removal, process monitoring, and support system functions to assess the adequacy

of Dominion's alternative shutdown methodology. The team also assessed whether

alternative post-fire shutdown could be perfo

rmed both with and without the availability of off-site power. The team walked down selected plant configurations to verify whether they were consistent with the assumptions and descriptions in the safe shutdown and fire hazards analyses. In addition, the team evaluated whether the systems and

components credited for use during post-fire safe shutdown would remain free from fire

damage.

The team reviewed the training program for licensed and non-licensed operators to verify whether it included alternative shutdown capability. The team also verified

whether personnel required for post-fire safe shutdown, using either the normal or

alternative shutdown methods, were trained and available on-site at all times, exclusive of those assigned as fire brigade members.

The team reviewed the adequacy of procedures utilized for post-fire shutdown and performed an independent walk through of procedure steps (i.e., a procedure tabletop)

to assess the adequacy of implementation and human factors within the procedures.

The team also evaluated the time required to perform specific actions to verify whether

operators could reasonably be expected to perform those actions within sufficient time to maintain plant parameters within specified limits.

Specific procedures reviewed for normal and alternative post-fire shutdown included the

following:

Unit 2 AOP 2559, Fire; AOP 2579A, Fire Procedure for Hot Standby Appendix R Fire Area R-1;

8 AOP 2579AA, Fire Procedure for Cooldown and Cold Shutdown Appendix R Fire

Area R-1; AOP 2579EE, Fire Procedure for Cooldown and Cold Shutdown Appendix R Fire

Area R-7, R-9, R-14, and R-17; AOP 2579G, Fire Procedure for Hot Standby Appendix R Fire Area R-7; and, AOP 2579M, Fire Procedure for Hot Standby Appendix R Fire Area R-14.

Unit 3 EOP 3509, Fire Emergency; EOP 3509.1, Control Room, Cable Spreading Area or Instrument Rack Room

Fire; EOP 3509.6, Auxiliary Building West MCC/Rod Control/ACU Area Fire; EOP 3509.15, North (A) EDG Enclosure or East (A) F.O. Vault Fire; and, EOP 3509.19, ESF Building North RHR Heat Exchanger Cubicle Fire.

The team reviewed selected operator manual actions to verify whether they had been properly reviewed and approved and whether the actions could be implemented in accordance with plant procedures in the time necessary to support the safe shutdown

method for each fire area. The team also reviewed the periodic testing of the alternative

shutdown transfer and isolation capability, and instrumentation and control functions, to

evaluate whether the tests were adequate to ensure the functionality of the alternative

shutdown capability.

b. Findings

No findings were identified.

.06 Circuit Analysis

a. Inspection Scope

The team verified that the licensee performed a post-fire safe shutdown analysis for the selected fire areas and the analysis appropriately identified the structures, systems, and components important to achieving and maintaining safe shutdown. Additionally, the

team verified that the licensee's analysis ensured that necessary electrical circuits were properly protected and that circuits that could adversely impact safe shutdown due to hot

shorts or shorts to ground were identified, evaluated, and dispositioned to ensure spurious actuations would not prevent safe shutdown.

The team's review considered fire and cable attributes, cable routing, potential

undesirable consequences and common power supply/bus concerns. Specific items

included the credibility of the fire threat, cable insulation attributes, cable failure modes,

and actuations resulting in flow diversion or loss of coolant events.

The team also reviewed cable raceway drawings and/or cable routing databases for a

sample of components required for post-fire safe shutdown to verify that cables were

9 routed as described in the safe shutdown analysis. The team also reviewed equipment important to safe shutdown, but not part of the success path, to verify that the licensee

had taken appropriate actions in accordance with the design and licensing basis and

NRC Regulatory Guide 1.189, Revision 2.

Cable failure modes were reviewed for the following components:

Unit 2 P18B, Charging Pump 'B'; 2-CH-501, VCT Outlet Header to Charging Pumps Isolation Valve; 2-CH-519, Loop 1A Charging Isolation Valve; and, PI-1023B-1, SG #2 Pressure Indicator.

Unit 3 3RCS*LCV459, VCT Letdown Isolation Valve; 3RCS*SV8095A, Head Vent Isolation Valve; 3CHS*MV8438A, Charging Pump 'A' Header Isolation Valve; 3FWS*LI501A, SG #1 Level Indicator; and, 3RCS*PI405B, RCS Pressure Indicator.

The team reviewed a sample of circuit breaker coordination studies to ensure equipment

needed to conduct post-fire safe shutdown activities would not be impacted due to a lack

of coordination that could result in a common power supply or common bus concern.

The team verified that the transfer of control from the control room to the alternative

shutdown location(s) would not be affected by fire-induced circuit faults (e.g. by the

provision of separate fuses and power supplies for alternative shutdown control circuits).

b. Findings

No findings were identified.

.07 Communications

a. Inspection Scope

The team reviewed safe shutdown procedures, the safe shutdown analysis, and

associated documents to verify an adequate method of communications would be

available to plant operators following a fire. During this review the team considered the effects of ambient noise levels, clarity of reception, reliability, and coverage patterns. The team also inspected the designated emergency storage lockers to verify the

availability of portable radios for the fire brigade and for plant operators. The team also

verified that communications equipment such as repeaters and transmitters would not be

affected by a fire.

10 b. Findings

No findings were identified.

.08 Emergency Lighting

a. Inspection Scope

The team observed the placement and coverage area of eight-hour emergency lights

throughout the selected fire areas to evaluate their adequacy for illuminating access and egress pathways and any equipment requiring local operation or instrumentation monitoring for post-fire safe shutdown. The team also verified that the battery power

supplies were rated for at least an eight-hour capacity. Preventive maintenance

procedures, the vendor manual, completed surveillance tests, and battery replacement

practices were also reviewed to verify that the emergency lighting was being maintained

consistent with the manufacturer's recommendations and in a manner that would ensure reliable operation.

b. Findings

No findings were identified.

.09 Cold Shutdown Repairs

a. Inspection Scope

The team reviewed Dominion's dedicated repair procedures, for components which might be damaged by fire and were required to achieve post-fire cold shutdown (CSD). The team evaluated selected CSD repairs to determine whether they could be achieved

within the time frames assumed in the design and licensing bases. In addition, the team

verified whether the necessary repair equipment, tools, and materials (e.g., pre-cut

cables with prepared attachment lugs) were available and accessible on site.

b. Findings

No findings were identified.

.10 Compensatory Measures

a. Inspection Scope

The team verified compensatory measures were in place for out-of-service, degraded, or

inoperable fire protection and post-fire safe shutdown equipment, systems, or features (e.g., detection and suppression systems and equipment, passive fire barriers, pumps, valves, or electrical devices providing safe shutdown functions or capabilities). The team evaluated whether the short term compensatory measures adequately

compensated for the degraded function or feature until appropriate corrective action

4OA3 Follow-up of Events and Notices of Enforcement Discretion (IP 71153)

.1 (Closed) Licensee Event Report (LER) 05000336/2013-003-00 (Unit 2): Postulated DC Ammeter Circuit Hot Shorts

On October 30, 2013, during a review of industry operating experience, Dominion

identified a postulated fire induced circuit failure involving unfused direct current (DC)

ammeter circuits for Millstone Power Station, Unit 2. The fire induced circuit failures could cause a secondary fire that could adversely affect safe shutdown equipment and cause a loss of alternate shutdown capability which is contrary to Unit 2 Renewed

Facility Operating License Condition 2.C.(3) and Appendix R requirements. The license

condition and regulation requires in part, post-fire safe shutdown cables remain free of

the effects of fire-induced cable faults during postulated fires. Specifically, the licensee

identified DC ammeter circuits for Unit 2, were not provided with overcurrent protection to limit fault current in the 125 volt (V) DC systems. Postulated fires that result in a short to ground concurrent with an opposite polarity short from the same battery could result in

excessive current flow in the ammeter wiring. The excessive current could heat-up the

conductor and could result in a secondary fire in another fire area. The secondary fire

could adversely affect safe shutdown equipment and cause a loss of alternate shutdown

13 capability. Dominion determined the cause of the condition was a latent design error that was made during plant construction involving the failure to include protective fuses

in DC ammeter circuits.

The licensee submitted LER 05000336/2013-003-00 to report this event in accordance with 10 CFR 50.73(a)(2)(ii)(B) as an unanalyzed condition that significantly degraded plant safety. The licensee entered this issue into their corrective action program as condition report number CR530987 and implemented compensatory measures in the

affected fire areas pending final resolution of the issue.

The licensee completed an engineering evaluation (RAS000244) of the issue and developed a design change (MP2-14-01007) to add fuses to the affected ammeter

circuits. Dominion completed the necessary modifications for all affected ammeter

circuits by May 7, 2014.

The significance and enforcement aspect of this issue are discussed in Section 4OA7.1 of this inspection report. LER 05000336/2013-003-00 is closed.

.2 (Closed) Licensee Event Report (LER) 05000336/2014-002-00 (Unit 2): DC Circuit Hot

Shorts On March 12, 2014, during a review of industry operating experience, Dominion identified postulated fire induced circuit failures involving unfused DC motor control

circuits for Millstone Power Station Unit 2. The postulated fire induced circuit failures could cause a secondary fire that could adversely affect fire safe shutdown equipment

contrary to Unit 2 Renewed Facility Operating License Condition 2.C.(3) and Appendix R requirements. The license condition and regulation requires in part, post-fire safe shutdown cables remain free of the effects of fire induced cable faults during postulated fires. Specifically, the licensee identified 125 V DC control and indication circuits for a

non-safety related main turbine emergency lube oil pump that was not provided with overcurrent protection. Postulated fires in the turbine battery room, the cable vault, the

plant equipment operator meeting area and the control room could cause failure of the unprotected 125 V DC circuits, which in turn could cause failure of the control circuits for safe shutdown equipment. Dominion determined the cause of the condition was a

manufacturer's design error that involved the failure to include protective fuses in DC

motor control circuits during plant construction.

The licensee submitted LER 05000336/2014-002-00 (Unit 2) to report this event in accordance with 10 CFR 50.73(a)(2)(ii)(B) as an unanalyzed condition that significantly degraded plant safety. The licensee entered this issue into their corrective action

program as condition report number CR541980 and implemented compensatory measures in the affected fire areas pending final resolution of the issue.

The licensee completed an engineering evaluation (RAS000252) of the issue and

developed a design change (MP2-14-01040) to add overcurrent protection (fuses) to

the affected motor control circuit. Dominion completed the necessary modifications for

the affected motor control circuit by May 5, 2014.

14 The significance and enforcement aspect of this issue are discussed in Section 4OA7.2 of this inspection report. LER 05000336/2014-002-00 (Unit 2) is closed.

.3 (Closed) Licensee Event Report (LER) 05000423/2014-002-00 (Unit 3): DC Circuit Hot

Shorts On March 12, 2014, during a review of industry operating experience, Dominion identified postulated fire induced circuit failures involving unfused DC motor control

circuits for Millstone Power Station Unit 3. The postulated fire induced circuit failures could cause a secondary fire that could adversely affect fire safe shutdown equipment contrary to Unit 3 Renewed Facility Operating License Condition 2.H and the branch technical condition (BTP) 9.5-1 requirements. The license

condition and the BTP requires in part, post-fire safe shutdown cables remain free

of the effects of fire-induced cable faults during postulated fires. Specifically, the

licensee identified 125 V DC control circuits for non-safety related main turbine emergency lube oil and a main generator emergency seal oil pumps that were not provided with overcurrent protection. Postulated fires in the turbine battery

switchgear area, the cable spreading room, the instrument rack room, and the

control room could cause failure of the unprotected 125 V DC control circuits,

which in turn could cause failure of control circuits for safe shutdown equipment. Dominion determined the cause of the condition was a manufacturer's design error that involved the failure to include protective fuses in DC motor control

circuits during plant construction.

The licensee submitted LER 05000423/2014-002-00 (Unit 3) to report this event in accordance with 10 CFR 50.73(a)(2)(ii)(B) as an unanalyzed condition that significantly degraded plant safety. The licensee entered this issue into their corrective action

program as condition report number CR541983 and implemented compensatory measures in the affected fire areas pending final resolution of the issue.

The licensee completed an engineering evaluation (RAS000253) of the issue and developed design change modifications (MP3-14-01071 and MP3-14-01092) to add overcurrent protection (fuses) to the affected motor control circuits. Dominion completed the necessary modifications for all affected motor control circuits by November 2, 2014.

The significance and enforcement aspect of this issue are discussed in Section 4OA7.3 of this inspection report. LER 05000289/2014-001-00 (Unit 3) is closed.

15 4OA6 Meetings, Including Exit

Exit Meeting Summary

The team presented the inspection results to Mr. John Daugherty, Site Vice President, Millstone Power Station, and other members of the site staff at an exit meeting on August 11, 2016. No proprietary information was included in this inspection report.

4OA7 Licensee-Identified Violations

The following violations of very low safety significance (Green) were identified by the

licensee and are violations of NRC requirements. These issues satisfy the criteria of the NRC Enforcement Policy of being dispositioned as Non-Cited Violations.

.1 LER 05000336/2013-003-00 (Unit 2) describes an unanalyzed condition in which Dominion identified their DC ammeter circuits were unfused. Specifically, Dominion did not provide overcurrent protection for wiring associated with DC ammeter indication in

the control room to prevent wires from overheating due to fire induced faults and

excessive currents flowing through the cable. With enough current flowing through the

cable, the potential existed that the overloaded ammeter wiring could damage system wiring or adjacent safety-related circuits in the cable raceways needed for post-fire safe shutdown. This condition could result in a loss of the associated safe shutdown

components or a secondary fire in another fire area. The failure to protect safe

shutdown cables from the effects of postulated fires was a performance deficiency.

This performance deficiency was a violation of Millstone Power Station, Unit 2, Renewed Facility Operating License Condition 2.C.(3), which requires in part, post-fire safe shutdown cables remain free of the effects of fire-induced cable faults during postulated

fires. Contrary to the above, Dominion identified they failed to meet this requirement and

the condition existed since initial construction of Unit 2. The issue was more than minor

because it was associated with the protection against external events (fire) attribute of the mitigating systems cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating

events to prevent undesirable consequences. The team determined that the finding was

of very low safety significance (Green), based IMC 0609, Appendix F, "Fire Protection

Significance Determination Process (SDP)," Phase 2 screening criteria.

The finding screened to Green based upon, task number 2.3.5, because the

affected cables were routed in alternate shutdown fire areas that are continually

manned or protected by detection and

automatic suppression systems. Remaining fire areas are protected by detection systems, automatic suppression

systems or rely on manual fire-fighting activities. Additionally, the cable construction is Institute of Electrical and Electronics Engineers (IEEE) 383 (thermoset) which decreases the likelihood of inter-cable and intra-cable

interactions. Based on a team walkdown, the team determined that the ammeter

cable routing was not routed near a credible fire ignition source in the affected

fire areas. Because this finding is of very low safety significance and had been entered into Dominion's corrective action program (CR530987), this violation is

16 being treated as a Green, licensee-identified NCV consistent with the NRC's Enforcement Policy.

.2 LER 05000336/2014-002-00 (Unit 2) describes an unanalyzed condition in which Dominion identified DC motor control circuits were unfused. Specifically, Dominion did not provide overcurrent protection for wiring associated with 125 V DC control circuits for a non-safety related main turbine emergency lube oil pump

to prevent wires from overheating due to fire induced faults and excessive

currents flowing through the cable. With enough current flowing through the

cable, the potential existed that the overloaded motor control wiring could damage adjacent control circuit wiring for components which are needed to achieve and maintain post-fire safe shutdown for a fire in several fire areas (turbine battery

room, cable vault, plant equipment operator meeting area, control room). This condition could result in a loss of the associated safe shutdown components or a

secondary fire in another fire area. The failure to protect safe shutdown cables from the effect of postulated fires was a performance deficiency.

This performance deficiency was a violation of Millstone Power Station, Unit 2,

Renewed Facility Operating License Condition 2.C.(3), which requires, in part, post-fire safe shutdown cables remain free of the effects of fire induced cable faults during

postulated fires. Contrary to the above, Dominion identified they failed to meet this

requirement and the condition existed since initial construction. The issue was more than minor because it was associated with the protection against external events (fire) attribute of the mitigating systems cornerstone and it adversely affected the

cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The team

determined that the finding was of very low safety significance (Green), based on IMC 0609, Appendix F, "Fire Protection Significance Determination Process," Phase 2

screening criteria.

The finding screened to Green based upon, task number 2.3.5, because the affected cables were routed in alternate shutdown fire areas that are continually manned or

protected by detection and automatic suppression systems. Remaining fire areas are

protected by detection systems, automatic suppression systems or rely on manual fire-fighting activities. Additionally, the cable construction is IEEE 383 (thermoset) which decreases the likelihood of inter-cable and intra-cable interactions. Based on a team walkdown, the team determined that the main turbine emergency lube oil pump cable routing was not routed near a credible fire ignition source in the affected fire areas.

Because this finding is of very low safety significance and had been entered into

Dominion's corrective action program (CR541980), this violation is being treated as a

Green, licensee-identified NCV consistent with the NRC's Enforcement Policy.

.3 LER 05000423/2014-002-00 (Unit 3) describes an unanalyzed condition in which Dominion identified DC motor control circuits were unfused. Specifically, Dominion did

not provide overcurrent protection for wiring associated with 125 V DC control circuits for

non-safety related main turbine emergency lube oil and main generator emergency seal oil pumps to prevent wires from overheating due to fire induced faults and excessive currents flowing through the cable. With enough current flowing through the cable, the

17 potential existed that the overloaded motor control wiring could damage adjacent control circuit wiring for components which are needed to achieve and maintain post-fire safe

shutdown for a fire in several fire areas (turbine battery switchgear area, cable spreading room, instrument rack room, control room). This condition could result in a loss of the
