Dear Mr. Chisum:
On April 15, 2015, the U.S. Nuclear Regulatory
Commission (NRC) completed an inspection at the Waterford Steam Electric Station, Unit 3, and discussed the results of this inspection with Mr. B. Lanka, Director, Engineering, and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.
NRC inspectors documented four findings of very low safety significance (Green) in this report. All of these findings involved violations of NRC requirements. The NRC is treating these violations as non-cited violations consistent with Section 2.3.2.a of the Enforcement Policy. Additionally, one finding involving 10 CFR 50.48(b) was identified and was a violation of NRC requirements. The inspectors have screened this finding and determined that it warrants enforcement discretion per the NRC Enforcement
Policy Section 9.1, "Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48)" and Section 11.05(b) of Inspection Manual
Chapter 0305 (EA-15-077).

- 2 - SUMMARY OF FINDINGS
IR 05000382/2015007; 01/26/2015 - 04/15/2015; Waterford Steam Electric Station, Unit 3; Triennial Fire Protection Team Inspection.
The report covered a two-week triennial fire protection team inspection by specialist inspectors from Region IV. Four findings of very low safety significance (Green) are documented in this
report. Four of these findings involved violations of NRC requirements. The significance of inspection findings is indicated by their color (i.e., Green, White, Yellow, or Red) which is determined using Inspection Manual Chapter 0609, "Significance Determination Process,"
dated June 2, 2011. Cross-cutting aspects are determined using Inspection Manual
Chapter 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. Violations
of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4.
Cornerstone: Mitigating Systems
- Green. The team identified a non-cited violation of License Condition 2.C.(9), "Fire Protection," for the failure to ensure the required separation between fire areas. Specifically, the licensee installed fire barriers on two ventilation ducts which were not in
a configuration demonstrated to provide the required three-hour fire-rated separation between fire areas. The licensee entered this issue into their corrective action program
as Condition Report CR-WF3-2015-00540 and established an hourly fire watch as a
compensatory measure until corrective actions can be taken (Fire Impairments 15-30
and 15-31).
The failure to ensure the required separation between fire areas was a performance
deficiency. The performance deficiency 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 evaluated this finding using Inspection
Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process,"
dated September 20, 2013. Both emergency diesel generator rooms were equipped
with pre-action sprinkler systems which would limit temperatures near the ceiling around the room exhaust ducts; therefore, the finding screened to Green at Section 1.4.3.C.
This finding did not have a cross-cutting aspect since it was not indicative of current
licensee performance since this fire barrier configuration was installed in the 1980s.
(Section 1R05.02.b)
- Green. The team identified a non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to adequately correct a previous violation. Specifically, the licensee failed to provide a bounding calculation for the amount of time available for operators to establish component cooling water during an alternative shutdown. The
licensee developed this calculation in response to Non-cited Violation 2012007-02.
The licensee entered this issue into their corrective action program as
- 3 - Condition Report CR-WF3-2015-0859 and implemented a fire impairment as a compensatory measure.
The failure to provide a bounding calculation for the amount of time available for
operators to establish component cooling water during an alternative shutdown was a
performance deficiency. The performance deficiency 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. A senior reactor analyst performed a
Phase 3 evaluation to determine the risk significance of this finding since it involved a postulated control room fire that led to control room evacuation and determined this
violation was of very low safety significance.
This finding had a cross-cutting aspect associated with resolution within the problem
identification and resolution area since the licensee failed to take effective corrective
actions to address issues in a timely manner commensurate with their safety
significance. Specifically, the team determined that the licensee's corrective actions were not effective since the licensee failed to provide a bounding calculation for the amount of time available for operators to establish component cooling water during an
alternative shutdown (P.3). (Section 1R05.05.b.1)
- Green. The team identified a non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to periodically test and demonstrate the 8-hour capacity of the Appendix R emergency lighting units. The licensee entered this issue into their
corrective action program as Condition Report CR-WF3-2015-00856 and operators had flashlights available as a compensatory measure.
The failure to periodically test and demonstrate the 8-hour capacity of the Appendix R
emergency lighting units was a performance deficiency. The performance deficiency
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
evaluated this finding using Inspection Manual Chapter 0609, Appendix F, "Fire
Protection Significance Determination Process," dated September 20, 2013. The team
assigned the finding a low degradation rating because it would not prevent reaching and maintaining safe shutdown conditions in the event of a control room fire. Specifically, the team had reasonable assurance that the emergency lighting units would provide
adequate illumination for a sufficient amount of time for operators to perform the most
time critical actions. In addition, the team determined that operators performing an
alternative shutdown had flashlights available in the Appendix R equipment lockers. Because the team assigned a low degradation rating, this finding screened as having very low safety significance.
This finding did not have a cross-cutting aspect since it was not indicative of present
performance in that the performance deficiency occurred more than three years ago. (Section 1R05.08.b.1)
- 4 - * Green. The team identified a non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to correct adverse conditions associated with fire protection. Specifically, the licensee failed to correct longstanding deficiencies with the Appendix R emergency lighting units. The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00593 and operators had flashlights
available as a compensatory measure.
The failure to correct longstanding deficiencies with the Appendix R emergency lighting
units was a performance deficiency. The performance deficiency 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 evaluated this finding using
Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process," dated September 20, 2013. The team assigned the finding a low degradation rating because the failure to provide adequate 8-hour emergency lights
at all locations would not prevent reaching and maintaining safe shutdown conditions in
the event of a control room fire. Specifically, the team determined that operators
performing an alternative shutdown had flashlights available in the Appendix R equipment lockers. Because the team assigned a low degradation rating, this finding screened as having very low safety significance.
This finding had a cross-cutting aspect associated with resolution within the problem
identification and resolution area since the licensee failed to take effective corrective
actions to address issues in a timely manner commensurate with their safety significance. Specifically, the team determined that the licensee failed to take corrective actions to address the nonfunctional emergency lighting units in a timely manner (P.3). (Section 1R05.08.b.2)

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R05 Fire Protection (71111.05T)
This report presents the results of a triennial fire protection inspection conducted in accordance with NRC Inspection Procedure 71111.05T, "Fire Protection (Triennial),"
at the Waterford Steam Electric Station, Unit 3. The licensee committed to adopt a
risk-informed fire protection program in accordance with National Fire Protection
Association 805 (NFPA-805), but has not yet completed the program transition. The team evaluated the implementation of the approved fire protection program in selected risk-significant areas with an emphasis on the procedures, equipment, fire barriers, and
systems that ensure the post-fire capability to safely shutdown the plant.
Inspection Procedure 71111.05T requires the selection of three to five fire areas and one or more mitigating strategies for review. The team used the Waterford Steam Electric Station, Unit 3, Fire PRA Summary Report to select the following three risk-significant
fire areas (inspection samples) for review:
Fire Area Description
RAB 6 Electrical Penetration Room A RAB 7 Relay Rooms (+35' Elevation) RAB 8 Switchgear Rooms
The team evaluated the licensee's fire protection program using the applicable
requirements, which included plant Technical Specifications, Operating License
Condition 2.C.(9), NRC safety evaluations, 10 CFR 50.48, and Branch Technical Position 9.5-1. The team also reviewed related documents that included the Final Safety Analysis Report, Section 9.5; the fire hazards analysis; and the post-fire safe shutdown
analysis. Specific documents reviewed by the team are listed in the attachment.
Three fire area inspection samples and one mitigating strategy sample were completed.
.01 Protection of Safe Shutdown Capabilities
a. Inspection Scope
The team reviewed the piping and instrumentation diagrams, safe shutdown equipment list, safe shutdown design basis documents, and the post-fire safe shutdown analysis to verify that the licensee properly identified the components and systems necessary to achieve and maintain safe shutdown conditions for fires in the selected fire areas. The
team observed walkdowns of the procedures used for achieving and maintaining safe
shutdown in the event of a fire to verify that the procedures properly implemented the safe shutdown analysis provisions.
- 6 - For each of the selected fire areas, the team reviewed the separation of redundant safe shutdown cables, equipment, and components located within the same fire area. The team also reviewed the licensee's method for meeting the requirements of
10 CFR 50.48; Branch Technical Position 9.5-1, Appendix A; and 10 CFR Part 50,
Appendix R,Section III.G. Specifically, the team evaluated whether at least one
post-fire safe shutdown success path remained free of fire damage in the event of a fire.
In addition, the team verified that the licensee met applicable license commitments.
b. Findings
No findings were identified.
.02 Passive Fire Protection
a. Inspection Scope
The team walked down accessible portions of the selected fire areas to observe the material condition and configuration of the installed fire area boundaries (including walls, fire doors, and fire dampers) and verify that the electrical raceway fire barriers were
appropriate for the fire hazards in the area. The team compared the installed
configurations to the approved construction details, supporting fire tests, and applicable
license commitments.
The team reviewed installation, repair, and qualification records for a sample of penetration seals to ensure the fill material possessed an appropriate fire rating and that
the installation met the engineering design. The team also reviewed similar records for
the rated fire wraps to ensure the material possessed an appropriate fire rating and that
the installation met the engineering design.
b. Findings
Introduction. The team identified a Green non-cited violation of License Condition 2.C.(9), "Fire Protection," for the failure to ensure the required separation
between fire areas. Specifically, the licensee installed fire barriers on two ventilation ducts which were not in a configuration dem
onstrated to provide the required three-hour fire-rated separation between fire areas.
Description. The approved fire protection program required fire areas to be separated by floors, walls, and ceilings having a three-hour fire resistance rating except as noted in the fire area analysis. The team reviewed surveillance Procedure ME-0003-009, "Fire-Rated Walls, Floors, and Ceilings," Revision 302. The procedure identified two fire
barriers which did not require inspection because they were encapsulated in metal
flashing.
- 7 - The emergency diesel generator (EDG) rooms were fire areas reactor auxiliary building (RAB) 15 (EDG B) and RAB 16 (EDG A). These rooms were below the ventilation mechanical room which is fire area RAB 2. The inlets to the EDG room exhaust fans were 72"x72" ducts which extended down from the ceilings and flared out
to larger openings. Fire Dampers FD-76 and FD-77 were located on the ends of the
ducts in fire area RAB 15 and RAB 16, respectively. Since the fire dampers were not in
the plane of the ceiling, the ductwork between the fire damper and the ceiling required
protection from the effects of a fire. Thermo-Lag material was installed on the ducts between the fire damper and the ceiling. Records show that three-hour rated materials were used; however, metal flashing was also installed encapsulating the fire barriers on
the ducts.
Thermo-Lag fire barriers are not passive insulating materials. Thermo-Lag sublimates when exposed to high temperatures. The gases generated during the process absorb heat which would otherwise be transferred to the item being protected. Encapsulating
the fire barriers with metal flashing restricts the release of gases. This is not a tested
configuration for Thermo-Lag fire barriers. While three-hour rated materials were used,
the effective fire resistance of the as-installed configuration is unknown.
Analysis. The failure to ensure the required separation between fire areas was a performance deficiency. The performance deficiency 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 evaluated this finding using Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance
Determination Process," dated September 20, 2013. The finding involved fire barrier
elements that separate one fire area from another; therefore, it was determined to be in
the fire confinement category in Inspection Manual Chapter 0609, Appendix F, Attachment 1, "Part 1: Fire Protection SDP Phase 1 Worksheet." Both EDG rooms are equipped with pre-action sprinkler systems (fully automated suppression system) which
would limit temperatures near the ceiling around the room exhaust ducts; therefore, the finding screened to Green in accordance with Section 1.4.3.C.
This finding did not have a cross-cutting aspect since it was not indicative of current licensee performance since this fire barrier configuration was installed in the 1980s.
Enforcement. License Condition 2.C(9), "Fire Protection," states, in part, "EOI [Entergy
Operations, Inc.] shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report for the facility through Amendment 36 and as approved in the safety evaluation report (SER) through Supplement 9." The Final Safety Analysis Report, Section 9.5.1.2.1, "Fire Containment,"
states, in part, "Ductwork penetrations through fire area/zone boundary walls, floors, and
ceilings are externally sealed to provide fire resistance rating of three hours." The Final
Safety Analysis Report, Section 9.5.1.3.1, "Detailed Comparison to Appendix "A" to the
Branch Technical Position APCSB 9.5-1, Revision 0," Item D.1.(j), states, in part, "Appendix R fire areas are isolated from each other by floors, walls, and ceilings having a fire resistance rating of three hours unless noted otherwise in the Fire Area-By-Area
- 8 - Analysis." The Final Safety Analysis Report, Section 9.5.1.3.2, "Fire Area-By-Fire Area Analysis," identifies the fire area design rating of three hours for the boundaries between fire areas RAB 2, RAB 15, and RAB 16. Contrary to the above, prior to February 13, 2015, the licensee failed to establish fire area boundaries having a fire resistance rating
of three hours. Specifically, two fire barriers protecting ventilation ducts between fire dampers and the room's ceilings are configured in a manner in which the fire resistance
rating is indeterminate.
Because this violation was of very low safety significance, has been entered into the corrective action program as Condition Report CR-WF3-2015-00540, and the licensee
has established an hourly fire watch as a compensatory measure until corrective actions can be taken, Fire Impairments 15-30 and 15-31, this violation is being treated as a
non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy: NCV 05000382/2015007-01, "Inadequate Fire Area Boundary."
.03 Active Fire Protection
a. Inspection Scope
The team reviewed the design, maintenance, testing, and operation of the fire detection
and suppression systems in the selected fire areas. The team verified the automatic
detection systems and the manual and automatic suppression systems were installed, tested, and maintained in accordance with the National Fire Protection Association code
of record or approved deviations and that each suppression system was appropriate for the hazards in the selected fire areas.
The team performed a walkdown of accessible portions of the detection and suppression
systems in the selected fire areas. The team also performed a walkdown of major
system support equipment in other areas (e.g., fire pumps) to assess the material condition of these systems and components.
The team reviewed the electric and diesel fire pumps' flow and pressure tests to verify
that the pumps met their design requirements. The team also reviewed the fire water
supply system flow and pressure tests to verify that the system capability met the design
requirements.
The team assessed the fire brigade capabilities by reviewing training, qualification, and
drill critique records. The team also reviewed 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. In addition, the team inspected fire brigade equipment to determine
operational readiness for fire-fighting.
The team observed an unannounced fire drill and subsequent drill critique on
February 12, 2015, using the guidance contained in Inspection Procedure 71111.05AQ, "Fire Protection Annual/Quarterly." The team observed fire brigade members fight a simulated fire in fire area RAB 15, EDG room B. The team verified that the licensee
- 9 - identified problems, openly discussed them in a self-critical manner at the drill debrief, and identified appropriate corrective actions. Specific attributes evaluated were (1) proper wearing of turnout gear and self-contained breathing apparatus; (2) proper use and layout of fire hoses; (3) employment of appropriate fire-fighting techniques; (4)
sufficient fire-fighting equipment was brought to the scene; (5) effectiveness of fire
brigade leader communications, command, and control; (6) search for victims and
propagation of the fire into other areas; (7) smoke removal operations; (8) utilization of
pre-planned strategies; (9) adherence to the pre-planned drill scenario; and (10) drill objectives.
b. Findings
No findings were identified.
.04 Protection From Damage From Fire Suppression Activities
a. Inspection Scope
The team performed plant walkdowns and document reviews to verify that redundant trains of systems required for hot shutdown, which are located in the same fire area,
would not be subject to damage from fire suppression activities or from the rupture or
inadvertent operation of fire suppression systems. Specifically, the team verified:
- A fire in one of the selected fire areas would not directly, through production of smoke, heat, or hot gases, cause activation of suppression systems that could potentially damage all redundant safe shutdown trains.
- A fire in one of the selected fire areas or the inadvertent actuation or rupture of a
fire suppression system would not directly cause damage to all redundant trains (e.g., sprinkler-caused flooding of other than the locally affected train).
- Adequate drainage is provided in areas protected by water suppression systems.
b. Findings
No findings were identified.
.05 Alternative Shutdown Capability
a. Inspection Scope
Review of Methodology
The team reviewed the safe shutdown analysis, operating procedures, piping and
instrumentation drawings, electrical drawings, the Final Safety Analysis Report, and
other supporting documents to verify that hot and cold shutdown could be achieved and maintained from outside the control room for fires that require evacuation of the control room, with or without offsite power available.
- 10 - The team conducted plant walkdowns to verify that the plant configuration was consistent with the description contained in the safe shutdown and fire hazards analyses. The team focused on ensuring the adequacy of systems selected for
reactivity control, reactor coolant makeup, reactor decay heat removal, process monitoring instrumentation, and support systems functions.
The team also verified that the systems and components credited for shutdown would remain free from fire damage. Finally, the team verified that the transfer of control from the control room to the alternative shutdown location 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).
Review of Operational Implementation
The team verified that licensed and non-licensed operators received training on
alternative shutdown procedures. The team also verified that sufficient personnel to
perform a safe shutdown were trained and available on-site at all times, exclusive of those assigned as fire brigade members.
The team performed a timed walkdown of the alternative shutdown procedure with
licensed and non-licensed operators to determine the adequacy of the procedure. The
team verified that the operators could reasonably be expected to perform specific actions within the time required to maintain plant parameters within specified limits. Time critical actions that were verified included restoring electrical power, establishing control at the remote shutdown panels, establishing reactor coolant makeup, and
establishing decay heat removal.
The team also reviewed the periodic testing of the alternative shutdown transfer capability and instrumentation and control functions to verify that the tests were adequate to demonstrate the functionality of the alternative shutdown capability.
b. Findings
.1 Introduction. The team identified a Green non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to adequately correct a previous violation. Specifically, the licensee failed to provide a bounding calculation for the amount of time available for
operators to establish component cooling water during an alternative shutdown. The
licensee developed this calculation in response to Non-cited Violation 2012007-02.
Description. During the 2012 triennial fire protection inspection, the team identified a violation for the failure to perform a safe shutdown design calculation. Specifically, the
team determined that the licensee failed to calculate the amount of time available for
operators to establish component cooling water to a running emergency diesel generator
that was providing power to safe shutdown components during an alternative shutdown.
The team documented this issue as Non-cited Violation 2012007-02, "Failure to Calculate Adequate Cooling Provided to Diesel Generator B within Required Time."
- 11 - The licensee entered this issue into their corrective action program as Condition
Report 2012-00818.
In response to this violation, the licensee developed Engineering Change EC-36621,
"Evaluate Impacts of Operating the Emergency Diesel Generators (EDGs) Without
Component Cooling Water." This engineering change revised Calculation EC-M12-001,
"Emergency Diesel Generator with no CCW Flow," which determined the amount of time
that an emergency diesel generator could run without component cooling water during an alternative shutdown prior to being damaged.
In Calculation EC-M12-001, the licensee first determined a worst case emergency diesel
generator load of 3.23 megawatt (MW) for an alternative shutdown without component
cooling water. The licensee then estimated the heat load for a running emergency diesel generator by fitting a second order polynomial to empirical data. The licensee estimated a heat load of approximately 5.65 MBTU/hr. when an emergency diesel
generator carried a load of 3.23 MW. Using this heat load of 5.65 MBTU/hr., the
licensee calculated an emergency diesel generator could run for 10 minutes without
component cooling water and not be damaged. The licensee used this result to support the 10-minute time-critical action for operators to establish component cooling water during an alternative shutdown.
The team reviewed Calculation EC-M12-001 and noted the empirical data demonstrated
the heat load near 3.23 MW was greater than the estimated heat load from the best fit
polynomial regression. The team concluded that the licensee's calculation was not bounding and operators had less than 10 minutes available to establish component cooling water during an alternative shutdown. During the timed walkdown of the
alternative shutdown procedure, the team determined that it would take operators
approximately 11 minutes to establish component cooling water.
Analysis. The failure to provide an appropriate bounding calculation for the amount of time available for operators to establish component cooling water during an alternative
shutdown was a performance deficiency. The performance deficiency 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 evaluated this finding using Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance
Determination Process," dated September 20, 2013, because it affected the ability to
reach and maintain safe shutdown conditions in case of a fire. A senior reactor analyst
performed a Phase 3 evaluation to determine the risk significance of this finding since it involved a postulated control room fire that led to control room evacuation.
For the control room, the senior reactor analyst assigned a generic fire ignition frequency
for the main control board (FIF
MCB) from NUREG/CR-6850, Table 6-1, "Fire Frequency Bins and Generic Frequencies." The analyst multiplied the fire ignition frequency by a
severity factor (SF) and a non-suppression probability indicating that operators failed to extinguish the fire within 20 minutes, assuming a 2-minute detection that required a
- 12 - control room evacuation (NP
CRE). The resulting control room evacuation frequency (F
CR) was: F CR = FIF MCB * SF * NP
= 2.5E-3/year * 0.1 * 1.3E-2
= 3.25E-6/year
The main control board had a total of 12 panels. The analyst determined that only a fire
in one of these panels (CP-8) could lead to the loss of component cooling water to the
emergency diesel generator. Therefore, a bounding change in core damage frequency
for a control room fire that leads to evacuation and the loss of the emergency diesel
generator (F
CRE+EDG) was determined to be:
F CR+EDG = F CR * (1 / 12)
= 3.25E-6/year * (1 / 12)
= 2.7E-7/year
For the cable vault, the senior reactor analyst
limited the risk determination to transient and hot work fires since there were no fixed ignition sources in the cable vault. The
senior reactor analyst assigned a low likelihood rating for transients and hot work activities in the cable vault. The senior reactor analyst then assigned a fire ignition frequency for transients (FIF
CV-TR) and hot work activities (FIFCV-HW) from Inspection Manual Chapter 0609, Appendix F, Attachment 4.
The senior reactor analyst determined that the floor area of the cable vault was 5778.5 square feet. The senior reactor analyst assigned a screening weighting factor (W) of 0.1 for transient and hot work fires. The senior reactor analyst noted that
the cable vault had smoke detectors and a pre-action automatic sprinkler system. The senior reactor analyst assigned a nominal failure probability of the sprinkler system
(P SPR) from Inspection Manual Chapter 0609, Appendix F, Task 2.7.4.
The senior reactor analyst calculated a bounding change in core damage frequency for a cable vault fire that leads to evacuation and the loss of the emergency diesel generator
(F CV+EDG) was determined to be:
F CV+EDG = (FIF TR + FIF HW) * W * NP
SPR = (5.5E-5/year + 2.3E-5/year) * 0.1 * 0.05
= 3.9E-7/year
Since fires in the control room are independent of fires in the cable vault, the senior reactor analyst calculated a bounding total change in core damage frequency (CDF TOT) for the performance deficiency by adding the change in core damage frequencies for the
- 13 - control room and cable vault calculated above. The senior reactor analyst calculated a bounding total change in core damage frequency of:
CDF TOT = F CR+EDG + FCV+EDG
= 2.7E-7/year + 3.9E-7/year
= 6.6E-7/year
This change in core damage frequency was considered to be bounding since it
assumed:
- A fire in any of the applicable main control board panels or the cable vault areas would cause a loss of offsite power and a loss of component cooling water, resulting in a loss of the emergency diesel generator;
- The conditional core damage probability given a control room fire with evacuation and the loss of the emergency diesel generator was equal to one, and
- The performance deficiency accounted for the entire change in core damage frequency (i.e., the baseline core damage frequency for this event was zero).
In accordance with the guidance in Inspection Manual Chapter 0609, Appendix H,
"Containment Integrity Significance Determination Process," dated May 6, 2004, the senior reactor analyst screened the performance deficiency for its potential risk contribution to large early release frequency since the bounding change in core damage
frequency provided a risk significance estimate greater than 1E-7/yr. Given that
Waterford has a large dry containment and that control room evacuation sequences do
not include steam generator tube ruptures or intersystem loss of coolant accidents, the
analyst determined that this example was not significant with respect to large early release frequency. The analyst determined this example was of very low risk significance (Green).
This finding had a cross-cutting aspect associated with Resolution within the Problem
Identification and Resolution area since the licensee failed to take effective corrective actions to address issues in a timely manner commensurate with their safety significance. Specifically, the team determined that the licensee's corrective actions were not effective since the licensee failed to provide a bounding calculation for the
amount of time available for operators to establish component cooling water during an
alternative shutdown (P.3).
Enforcement. License Condition 2.C.9, "Fire Protection," states, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report for the facility through
Amendment 36 and as approved in the Safety
Evaluation Report through Supplement 9. Final Safety Analysis Report, Section 9.5.1.3.1.C, states that the fire protection program quality assurance program is documented in Procedure UNT-005-013, "Fire Protection
- 14 - Program." Procedure UNT-005-013, Section 5.8.8, states, in part, that conditions adverse to quality relating to the fire protection program will be identified and corrected.
Contrary to the above, from September 5, 2012, to April 15, 2015, the licensee failed to
implement and maintain in effect all provisions of the approved fire protection program. Specifically, the licensee failed to correct a condition adverse to fire protection since the licensee failed to perform an appropriate bounding calculation for the amount of time
available for operators to establish component cooling water during an alternative shutdown. The licensee developed this calculation as a corrective action for Non-cited Violation 2012007-02, "Failure to Calculate Adequate Cooling Provided to Diesel
Generator B within Required Time."
The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00859 and implemented Fire Impairment 15-045 as a compensatory measure. Because this violation was of very low safety significance and has been entered into the corrective action program, this violation is being treated as a
non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy:
NCV 05000382/2015007-02, "Failure to Provide a Bounding Calculation for Time Critical Actions."
.2 Introduction. The team identified a violation of Technical Specification 6.8.1.f for the failure to implement and maintain adequate written procedures covering fire protection
program implementation. Specifically, the team identified four examples where the licensee failed to maintain an alternative shutdown procedure that successfully mitigated all postulated alternative shutdown scenarios. This finding affects 10 CFR 50.48 and has been screened and determined to warrant enforcement discretion per the Interim
Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues
Description. The licensee used Procedure OP-901-502, "Evacuation of Control Room and Subsequent Plant Shutdown," Revision 28, to shut down the reactor from the
remote shutdown panel in the event a control room or cable vault fire required
evacuation of the control room. This alternative shutdown procedure provided steps for
operators to transfer control of the credited safe shutdown equipment away from the
control room to the remote shutdown panel and to achieve and maintain safe shutdown conditions from the remote shutdown panel.
The team performed a timed walkdown of the alternative shutdown procedure. Based
on the walkdown results, the team determined that the alternative shutdown procedure
was not adequate to ensure that operators could successfully mitigate all postulated alternative shutdown scenarios. In particular, the team identified the following four scenarios where operators may not be able to achieve and maintain a safe shutdown:
Example 1: Potential Loss of Credited Safe Shutdown Pumps
The first scenario involved fire damage resulting in blown fuses for either the component cooling water or emergency feedwater pumps. In this scenario, the team determined the operators would be unable to control the affected pump from the remote shutdown
- 15 - panel, but the operators would be able to control the affected pump by manually operating the breakers that supplied power to the motors. The team noted that the alternative shutdown procedure did not provide any steps for operators to manually operate the breakers to control these pumps, which were required for safe shutdown.
Example 2: Potential Spurious Opening of the Atmospheric Dump Valves
The second scenario involved the spurious actuation of two atmospheric dump valves. The team noted that the licensee previously had a 10-minute requirement for operators to mitigate the spurious actuation of two atmospheric dump valves by taking manual
control of an open atmospheric dump valve lo
cally and then manually closing the valve. The team determined that the alternative shutdown procedure provided steps for
operators to manually close an open atmospheric dump valve; however, the licensee removed the 10-minute requirement for operators to be able to perform this action.
The licensee removed the 10-minute requirement based on its understanding that the
spurious actuation of only one atmospheric dump valve was required to be analyzed and
mitigated. The team referred to guidance in Regulatory Guide 1.189, Revision 2, which stated, in part, "after control of the plant is achieved by the alternative or dedicated shutdown system, single or multiple spurious actuations that could occur in the fire-
affected area should be considered..."
The team reviewed the licensee's method for isolating the atmospheric dump valves
from the effects of a control room or cable vault fire. The team determined that the circuits responsible for isolating the atmospheric dump valves were located within the control room complex and, therefore, could not be relied upon to isolate the atmospheric
dump valves in the event of a control room fire. The team concluded that the licensee
should have maintained the 10-minute requirement in the alternative shutdown
procedure for operators to manually close a spuriously open atmospheric dump valve.
During the timed walkdown of the alternative shutdown procedure, the team determined that it would take operators approximately 13 minutes to close a spuriously open
atmospheric dump valve.
Example 3: Potential Spurious Opening of a Pressurizer Spray Valve
The third scenario involved the spurious opening of a pressurizer spray valve. In this
scenario, the open pressurizer spray valve results in a rapid depressurization of the
reactor coolant system, which could negatively impact the ability to achieve and maintain
natural circulation.
The licensee considered this scenario in the safe shutdown analysis. The licensee did
not perform an analysis or calculation to determine the amount of time operators had
available to mitigate this scenario. Instead, the licensee used engineering judgment to
specify that operators had 10 minutes available to secure the spurious spray flow.
The team was concerned that the 10-minute limit may not be sufficient to ensure that operators could achieve and maintain natural circulation. In response to the team's
- 16 - concern, the licensee modeled this scenario on the simulator. The team noted that the
use of the simulator was not a preferred method; however, it provided a reasonable
estimate for the amount of time available.
The results of the simulator run indicated that the reactor coolant system would reach
saturation pressure in less than 8 minutes. Once the reactor coolant system reaches
saturation pressure, voiding begins in the reactor coolant system. This voiding could
then negatively impact the ability to achieve and maintain natural circulation.
The team determined that the alternative shutdown procedure provided steps for
operators to trip the reactor coolant pumps, which would mitigate this scenario by
eliminating flow through the pressurizer spray valves. During the timed walkdown of
the alternative shutdown procedure, the team determined that it would take operators approximately 9 minutes and 15 seconds to trip all of the reactor coolant pumps.
Scenario 4: Potential Overfilling of the Steam Generators
The fourth scenario involved the potential overfilling of the steam generators. In this scenario, the open main steam isolation valves continue to provide steam to the turbine-driven main feedwater pumps, which continue to inject feedwater into the steam
generators until they overfill.
The team noted that the action to close the main steam isolation valves prior to
evacuating the control room was an operator action within the fire area. The team determined that this action was not credited in the plant's approved fire protection
program; therefore, the operators must take action outside of the control room to ensure that the main steam isolation valves were closed.
Because the licensee did not have an analysis establishing a time limit, the team was concerned the operators may not perform this action prior to main feedwater overfilling the steam generators. In response to the team's concern, the licensee modeled this
scenario on the simulator. The team noted that the use of the simulator was not a
preferred method; however, it provided a reasonable estimate for the amount of time
available.
The results of the simulator run indicated that the continued injection of main feedwater at full flow could overfill the steam generators in approximately 2 minutes and 30 seconds. The team noted that overfilling the steam generators would negatively
impact the ability to remove decay heat.
The team determined that the alternative shutdown procedure provided steps for operators to close the main steam isolation valves from outside the control room, which would mitigate this scenario by eliminating steam flow to the turbine-driven main
feedwater pumps. During the timed walkdown of the alternative shutdown procedure,
the team determined that it would take operators approximately 4 minutes and
30 seconds to close all of the main steam isolation valves.
- 17 - Analysis. The failure to implement and maintain adequate written procedures covering fire protection program implementation was a performance deficiency. The performance deficiency was more than minor because it was associated with the procedure quality 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. A senior reactor analyst
performed a calculation to bound the risk significance of this finding. The senior reactor
analyst determined that the finding was not of high safety significance. As discussed below, the team consulted the NRC Enforcement Policy, Section 9.1, "Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48)," to determine if the
noncompliance was eligible for enforcement discretion.
This finding did not have a cross-cutting aspect because it qualified for enforcement discretion.
Enforcement. Technical Specification 6.8.1.f states that written procedures shall be established, implemented, and maintained covering fire protection program
implementation. Licensee Procedure OP-901-502, "Evacuation of Control Room and Subsequent Plant Shutdown," Revision 28, implemented alternative shutdown outside of the control room. Contrary to the above, prior to April 15, 2015, the licensee failed to
implement and maintain written procedures covering fire protection program
implementation. Specifically, the team identified four scenarios where the licensee failed to ensure that the alternative shutdown procedure was adequate to ensure that
operators could mitigate all postulated alternative shutdown scenarios.
Because the licensee committed to adopting National Fire Protection Association
Standard 805, "Performance-Based Standard for Fire Protection for Light Water Reactor
Electric Generating Plants," and has committed to changing their fire protection program
license basis to comply with 10 CFR 50.48(c) by submitting a license amendment
request to the NRC, this violation was eligible for enforcement discretion as described in Section 9.1 of the Enforcement Policy, "Enforcement Discretion for Certain Fire
Protection Issues (10 CFR 50.48)."
Specifically, the team determined that the licensee: (1) would have identified the violation in light of the defined scope, thoroughness, and schedule of its transition to 10 CFR 50.48(c) because the licensee was performing new analyses and revising the alternative shutdown procedure for the transition to NFPA-805; (2) the licensee will
correct the violation after completing its transition to 10 CFR 50.48(c) and took
immediate corrective action and compensatory measures within a reasonable time
commensurate with the risk significance of the issue following identification; (3) routine licensee efforts were not likely to have previously identified the violation; (4) the violation was not willful; and (5) the team determined that this violation was not of high safety
significance. The finding also met additional discretion criteria established in
Section 11.05.b of Inspection Manual Chapter 0305, "Operating Reactor Assessment
Program."
- 18 - The licensee entered these issues into its corrective action program as Condition Reports CR-WF3-2015-00833, CR-WF3-2015-00857, CR-WF3-2015-00858, CR-WF3-2015-01871, CR-WF3-2015-01872, and CR-WF3-2015-01873, and implemented Fire Impairments15-041 thr
ough 15-045 as compensatory measures. Since all the criteria for the use of enforcement discretion were met, the NRC is
exercising enforcement discretion to not cite this violation in accordance with the
Interim Enforcement Policy regarding "Enforcement Discretion For Certain Fire
Protection Issues (10 CFR 50.48)." This use of enforcement discretion is documented
in the Enforcement Tracking System as EA-2015-077.
.06 Circuit Analysis
a. Inspection Scope
The team reviewed the post-fire safe shutdown analysis to verify that the licensee
identified the circuits that may impact the ability to achieve and maintain safe shutdown.
The team verified, on a sample basis, that the licensee properly identified the cables for
equipment required to achieve and maintain hot shutdown conditions in the event of a fire in the selected fire areas. The team verified that these cables were either adequately protected from the potentially adverse effects of fire damage or were
analyzed to show that fire-induced circuit faults (e.g., hot shorts, open circuits, and
shorts to ground) would not prevent safe shutdown.
The team's evaluation focused on the cables of selected components from the reactor coolant system, refueling water storage tank, component cooling water, auxiliary component cooling water, main steam isolation, atmospheric steam dumps, emergency
feed water, emergency diesel, low pressure safety injection, and chemical volume and
control system. For the sample of components selected, the team reviewed electrical
elementary and block diagrams and identified power, control, and instrument cables necessary to support their operation. In addition, the team reviewed cable routing information to verify that fire protection features were in place as needed to satisfy the
separation requirements specified in the fire protection license basis. Specific
components reviewed by the team are listed in the attachment.
b. Findings
No findings were identified.
.07 Communications
a. Inspection Scope
The team inspected the contents of designated emergency storage lockers and
reviewed the alternative shutdown procedure to verify that portable radio
communications and fixed emergency communications systems were available,
operable, and adequate for the performance of designated activities. The team verified the capability of the communication systems to support the operators in the conduct and coordination of their required actions. The team also verified that the design and
- 19 - location of communications equipment such as repeaters and transmitters would not cause a loss of communications during a fire. The team discussed system design, testing, and maintenance with the system engineer.
b. Findings
No findings were identified.
a. Inspection Scope
The team reviewed the portion of the emergency lighting system required for alternative shutdown to verify that it was adequate to support the performance of manual actions required to achieve and maintain hot shutdown conditions and to illuminate access and
egress routes to the areas where manual actions would be required. The team
evaluated the locations and positioning of the emergency lights during a walkdown of the
alternative shutdown procedure.
The team verified that the licensee installed emergency lights with an 8-hour capacity,
maintained the emergency light batteries in accordance with manufacturer
recommendations, and tested and performed maintenance in accordance with plant
procedures and industry practices.
b. Findings
.1 Introduction. The team identified a Green non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to periodically test and demonstrate the 8-hour capacity
of the Appendix R emergency lighting units.
Description. In 2004, the licensee discontinued the performance of 8-hour discharge tests for the Appendix R emergency lighting units. Specifically, the licensee removed
the requirement to perform the discharge tests from Procedure ME-004-445, "Self
Contained Battery Powered Emergency Lighting Unit." In lieu of performing discharge
tests, the licensee implemented a preventive maintenance program that replaced the emergency lighting unit batteries every three years.
The licensee documented their justification in Engineering Request ER-W3-2004-0222,
"Alternative Methodology for Appendix R 8-Hour Battery Powered Emergency Light
Testing," Revision 0. This engineering request referenced guidance contained in EPRI TR-106826, "Battery Performance Monitoring by Internal Ohmic Measurements."
The team reviewed the engineering request and the EPRI report and determined that the
licensee incorrectly applied the results of the EPRI report. Specifically, the team noted
that the objective of the EPRI report was to determine the extent to which internal ohmic
measurements could replace or reduce the frequency of discharge tests for emergency lighting units. Based on the favorable test results, EPRI recommended using internal ohmic measurements in lieu of discharge tests for two types of emergency lighting units.
- 20 - The team noted that the licensee did not use either of these two types of emergency lighting units, nor did the EPRI report recommend discontinuing discharge tests for any
other types of emergency lighting units.
In addition to referencing the EPRI report, the licensee made the following statements
regarding the discharge tests:
- No specific regulatory or OEM requirement was found that requires the 8-hour discharge test.
- The 8-hour capacity of the unit is a design function which is applicable to component selection and does not require periodic re-verification.
- The unit's self-diagnostic circuit monitors the battery capacity which is the equivalent to the current discharge test.
The team reviewed the fire protection program described in Procedure UNT-005-013,
"Fire Protection Program," Revision 12, and determined that it required the licensee to
periodically test the emergency lighting units to ensure that the equipment will function properly and continue to meet their design criteria (i.e., have an 8-hour battery capacity). The team noted that the licensee failed to consider this requirement when changing
Procedure ME-004-445. Finally, the team reviewed the licensee's justification and the
vendor's information and did not find evidence to support the statement that the unit's self-diagnostic circuit monitoring was sufficient to demonstrate the required 8-hour
battery capacity.
Analysis. The failure to periodically test and demonstrate the 8-hour capacity of the Appendix R emergency lighting units was a performance deficiency. The performance
deficiency 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 evaluated this finding using Inspection Manual Chapter 0609, Appendix F,
"Fire Protection Significance Determination Process," dated September 20, 2013, because it affected the ability to reach and maintain safe shutdown conditions in case of a fire. The team assigned the finding to the post-fire safe shutdown category since it
impacted the alternate shutdown element. The team assigned the finding a low
degradation rating because the failure to periodically test and demonstrate the 8-hour
capacity of the Appendix R emergency lighting units would not prevent reaching and maintaining safe shutdown conditions in the event of a control room fire. Specifically, the team had reasonable assurance that the emergency lighting units would provide
adequate illumination for a sufficient amount of time for operators to perform the most
time critical actions. In addition, the team determined that operators performing an
alternative shutdown had flashlights available in the Appendix R equipment lockers. Because the team assigned a low degradation rating, in accordance with Inspection Manual Chapter 0609, Appendix F, Step 1.3.1.B, this finding screened as having very low safety significance (Green).
- 21 - This finding did not have a cross-cutting aspect since it was not indicative of present performance in that the performance deficiency occurred more than three years ago.
Enforcement. License Condition 2.C.9, "Fire Protection," states, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report for the facility through
Amendment 36 and as approved in the Safety
Evaluation Report through Supplement 9. Final Safety Analysis Report, Section 9.5.1.3.1.C, states that the fire protection program quality assurance program is documented in Procedure UNT-005-013, "Fire Protection
Program." Procedure UNT-005-013, Step 5.8.5.2.d, states that fire protection
equipment, emergency lighting, and communication equipment are tested periodically to
assure that the equipment will function properly and continue to meet the design criteria. Contrary to the above, from April 15, 2004, to April 15, 2015, the licensee failed to implement a provision of the approved fire protection program. Specifically, the licensee failed to periodically test the emergency lights to assure that the lights will function
properly and continue to meet their design criteria.
The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00856 and operators have flashlights available as a
compensatory measure. Because this violation was of very low safety significance and has been entered into the corrective action program, this violation is being treated as a
non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy:
NCV 05000382/2015007- 03, "Failure to Periodically Test Emergency Lighting Units."
.2 Introduction. The team identified a Green non-cited violation of License Condition 2.C.9, "Fire Protection," for the failure to correct adverse conditions associated with fire
protection. Specifically, the licensee failed to correct long-standing deficiencies with the Appendix R emergency lighting units.
Descriptions. During the team's walkdown of the alternative shutdown procedure and subsequent discussions with the licensee's engineering staff, the team identified three
Appendix R emergency lighting units with longstanding deficiencies that had not been
corrected. At the time of inspection, three lights remained nonfunctional for
approximately 3 to 6 years. The three impaired emergency lighting units were:
- LTE-EBLT-324-8B - This light was located in the remote shutdown room. This light was identified as impaired on January 9, 2009, in Work Request 151869. This work request was scheduled to be completed on August 26, 2015. No
condition report was generated at the time of discovery.
- LTE-EBLT-321-20B - This light was located near the main steam isolation valve area. This light was first identified as impaired on March 2, 2010, in Condition Report CR-WF3-2010-01369. This light was scheduled to be repaired under Work Request 192775. This work request was scheduled to be completed on
July 14, 2015.
- 22 - * LTE-EBLT-320-14E - This light was located near the main steam isolation valve area. This light was first identified as impaired on February 16, 2012, in Condition Report CR-WF3-2012-00840. This light was scheduled to be repaired
under Work Request 264052. At the time this finding was identified, a completion date for this work request has not been scheduled.
The team determined that there was no practical reason for the lights to have not been
repaired in a timely manner.
Analysis. The failure to correct long-standing deficiencies with the Appendix R emergency lighting units was a performance deficiency. The performance deficiency 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 evaluated this finding using Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process," dated September 20, 2013, because it
affected the ability to reach and maintain safe shutdown conditions in case of a fire. The
team assigned the finding to the post-fire safe shutdown category since it impacted the
alternate shutdown (control room abandonment) element. The team assigned the finding a low degradation rating because the failure to provide adequate 8-hour emergency lights at all locations would not prevent reaching and maintaining safe
shutdown conditions in the event of a control room fire. Specifically, the team
determined that operators performing an alter
native shutdown had flashlights available in the Appendix R equipment lockers. Because the team assigned a low degradation
rating in accordance with Inspection Manual Chapter 0609, Appendix F, Step 1.3.1.B, this finding screened as having very low safety significance (Green).
This finding had a cross-cutting aspect associated with resolution within the problem
identification and resolution area since the licensee failed to take effective corrective
actions to address issues in a timely manner commensurate with their safety significance. Specifically, the team determined that the licensee failed to take corrective actions to address the nonfunctional emergency lighting units in a timely manner (P.3).
Enforcement. License Condition 2.C.9, "Fire Protection," states, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report for the facility through Amendment 36 and as approved in the Safety
Evaluation Report through Supplement 9. Final Safety Analysis Report, Section 9.5.1.3.1.C, states that the fire protection program
quality assurance program is documented in Procedure UNT-005-013, "Fire Protection
Program." Procedure UNT-005-013, Section 5.8.8, states, in part, that conditions
adverse to quality relating to the fire protection program will be identified and corrected. Contrary to the above, from 2009 to April 15, 2015, the licensee failed to implement and maintain in effect all provisions of the approved fire protection program. Specifically, the licensee failed to correct long-standing deficiencies with the Appendix R emergency
lighting units.
- 23 - The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00593 and operators had flashlights available as a compensatory measure. Because this violation was of very low safety significance and has been entered into the corrective action program, this violation is being treated as a non-cited
violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy:
NCV 05000382/2015007-04, "Failure to Correct Long Standing Deficiencies with the
Appendix R Emergency Lighting Units."
.09 Cold Shutdown Repairs
a. Inspection Scope
The team evaluated whether the licensee identified repairs needed to reach and maintain cold shutdown and had dedicated repair procedures, equipment, and materials to accomplish these repairs. Using these procedures, the team evaluated whether these
components could be repaired in time to bring the plant to cold shutdown within the
timeframes specified in their design and licensing bases. The team reviewed whether
the repair equipment, components, tools, and materials needed for the repairs were available and accessible on site.
b. Findings
No findings were identified.
.10 Compensatory Measures
a. Inspection Scope
The team verified that compensatory measures were implemented 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; or pumps, valves, or electrical devices providing safe shutdown functions). The team also verified that the short-term compensatory measures compensated for the
degraded function or feature until appropriate corrective action could be taken and that
the licensee was effective in returning the equipment to service in a reasonable period of
time.
The team reviewed operator manual actions cred
ited for achieving hot shutdown for fires that do not require an alternative shutdown. The team verified that operators could
reasonably be expected to perform the actions within the applicable shutdown time requirements. The team reviewed these operator manual actions using the guidance contained in NUREG-1852, "Demonstrating the Feasibility and Reliability of Operator
Manual Actions in Response to Fire," dated October 2007.
b. Findings
No findings were identified.
- 24 - .11 Review and Documentation of Fire Protection Program Changes
a. Inspection Scope
The team reviewed changes which occurred from February 17, 2012, to April 15, 2015,
to the approved fire protection program. The team verified that the changes did not
constitute an adverse effect on the ability to safely shutdown.
b. Findings
No findings were identified.
.12 Control of Transient Combustibles and Ignition Sources
a. Inspection Scope
The team reviewed the licensee's approved fire protection program, implementing
procedures, and programs for the control of ignition sources and transient combustibles. The team assessed the licensee's effectiveness in preventing fires and in controlling combustible loading within limits established in the fire hazards analysis. The team
performed plant walkdowns to independently verify that transient combustibles and
ignition sources were being properly controlled in accordance with the administrative
controls.
b. Findings
No findings were identified.
.13 Alternative Mitigation Strategy Inspection Activities
a. Inspection Scope
The team reviewed the licensee's implementation of guidance and strategies intended to
maintain or restore core, containment, and spent fuel pool cooling capabilities under the
circumstances associated with loss of large areas of the plant due to explosions or fire as required by Section B.5.b of the Interim Compensatory Measures Order, EA-02-026, dated February 25, 2002, and 10 CFR 50.54(hh)(2).
The team reviewed the strategies to verify that the licensee continued to maintain and
implement procedures, maintain and test equipment necessary to properly implement the strategies, and ensure station personnel were knowledgeable and capable of implementing the procedures. The team performed a visual inspection of portable
equipment used to implement the strategy to ensure the availability and material
readiness of the equipment, including the adequacy of portable pump trailer hitch
attachments, and verify the availability of onsite vehicles capable of towing the portable
pump. The team assessed the offsite ability to obtain fuel for the portable pump and foam used for firefighting efforts. The team reviewed the following strategies described
- 25 - in Procedure S-SAMG-1, "Loss of Large Areas of the Plant Due To Fire/Explosion,"
Revision 16:
