The report covers a two-week triennial fire protection team inspection by specialist inspectors from Region IV. One finding, which was a non-cited violation, was documented. The

significance of inspection findings is indicated by their color (i.e., Green, White, Yellow, or Red)

and determined using Inspection Manual Chapter 0609, "Significance Determination Process," dated April 29, 2015. Cross-cutting aspects are determined using Inspection Manual Chapter 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. All

violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement

Policy, dated November 1, 2016. The NRC's program for overseeing the safe operation of

commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process,"

Revision 6.

A. NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green. The team identified a non-cited violation of License Condition 2.E for the failure to provide 8-hour emergency lighting in all areas where operators perform manual actions required during an alternative shutdown. As a compensatory measure, the

licensee added flashlights to the procedure box in the essential cooling water intake

structure. The team noted that operators were also required to carry a flashlight while on shift. The licensee entered this issue into their corrective action program as

Condition Report 17-1741.

The failure to provide 8-hour emergency lighting in all areas where operators perform

manual actions required during an alternativ

e 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. Specifically, the failure to

provide 8-hour emergency lighting could adversely affect the ability of operators to perform the manual actions required for an

alternative shutdown.

The team determined this finding affected the Mitigating Systems Cornerstone. The

team evaluated this finding using Ins

pection 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 determined this finding was of very low safety significance (Green) in Task 1.3.1 because it had a low degradation rating.

The 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.

Specifically, the team determined that the performance deficiency existed since original construction. (Section 1R05.08)

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 at

South Texas Project Electric Generating Station, Units 1 and 2 in accordance with NRC Inspection Procedure 71111.05T, "Fire Protection (Triennial)," dated January 31, 2013. The inspection 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 inspection team used the fire hazards

analysis section of the South Texas Project Electric Generating Station, Units 1 and 2

Individual Plant Examination of External Events to select the following five risk-significant

fire areas (inspection samples) for review:

• Fire Area 20 Non-Radiological Pipe Chase

• Fire Area 32 Component Cooling Water Pipe Chase

• Fire Area 51 Train D Auxiliary Pump Room

• Fire Area 1 Control Room

• Fire Area 7 Alternate Shutdown Room

The inspection team evaluated the licensee's fire protection program using the

applicable requirements, which included the plant Technical Specifications, Operating License Condition 2.E, NRC safety evaluations, 10 CFR 50.48, and Branch Technical Position 9.5-1. The team also reviewed related documents that included the Updated

Final Safety Analysis Report (UFSAR), 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.

Five 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

4 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.

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

No findings were identified.

.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

5 system support equipment in other areas (e.g., fire pumps and Halon supply systems) 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 halon

suppression functional 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 firefighting.

The team observed an unannounced fire drill and subsequent drill critique on

February 8, 2017, using the guidance contained in Inspection Procedure 71111.05AQ,

"Fire Protection Annual/Quarterly," dated September 30, 2010. The team observed fire brigade members fight a simulated fire in the isolation valve cubicle, located outside the radiological controlled area. The team verified that the licensee 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 firefighting techniques; (4) sufficient firefighting 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).

6 * Adequate drainage was 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 Updated 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.

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 an alternative shutdown were trained and available onsite at all times, exclusive of those assigned as fire brigade members.

The team performed a timed walkdown of the alternative shutdown procedure for Unit 2 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 and local 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.

7 b. Findings

No findings were identified.

.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

emergency diesel generator, component cooling water, auxiliary feedwater, high head safety injection, low head safety injection, pressurizer power operated relief valves (PORV's), PORV block valves, alternative shutdown control room isolation and transfer switches, 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 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.

8 .08 Emergency Lighting

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

Introduction. The team identified a Green non-cited violation of License Condition 2.E for the failure to provide 8-hour emergency lighting in all areas where operators perform

manual actions required during an alternative shutdown.

Description. During a walkdown of the alternative shutdown procedure, the team identified four areas where the 8-hour emergency lighting was not sufficient for operators

to perform manual actions required during

an alternative shutdown. The four areas, manual actions, and associated procedure sections are provided in the table below.

Area Manual Action (Procedure Step) Electrical Auxiliary Building Penetration

Space (train A)

De-energize valve 2-CC-MOV-0339 (Addendum 20) Electrical Auxiliary Building Penetration

Space (train B)

De-energize valve 2-CC-MOV-0356 (Addendum 21) Essential Cooling Water Intake Structure (train B)

De-energize dampers HZ-FV-9895/9895A (Addendum 5, Step 2.0) Essential Cooling Water Intake Structure (train C)

De-energize dampers HZ-FV-9896/9896A (Addendum 5, Step 2.0)

In response to the team's request, the licensee conducted a blackout test to evaluate the

adequacy of the 8-hour emergency lighting in the essential cooling water intake structure (train B). This blackout test confirmed the team's determination that the 8-hour emergency lighting in the room was not sufficient for operators to de-energize dampers

HZ-FV-9895/9895A.

9 As a compensatory measure, the licensee added flashlights to the procedure box in the Essential Cooling Water Intake Structure. The team noted that operators were also

required to carry a flashlight while on shift.

Analysis. The failure to provide 8-hour emergency lighting in all areas where operators perform manual actions required 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. Specifically, the failure to provide 8-hour emergency lighting could adversely affect the ability of operators to perform the manual

actions required for an alternative shutdown.

The team determined this finding affected the Mitigating Systems Cornerstone. The team evaluated this finding using Ins

pection 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 remote shutdown and control room abandonment element. Using Inspection Manual Chapter 0609, Appendix F, Attachment 2, "Degradation Rating Guidance Specific to

Various Fire Protection Program Elements," dated February 28, 2005, the team

assigned the finding a low degradation rating since the ability to reach and maintain safe

shutdown conditions in the event of a control room fire would be minimally impacted by the failure to provide 8-hour emergency lighting in the four areas. Specifically, the team determined that operators were required to carry flashlights while on shift and these flashlights would be sufficient for operators to perform the required manual actions.

Because this finding had a low degradation rating, it screened as having very low safety

significance (Green) in Task 1.3.1.

The 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.

Specifically, the team determined that the performance deficiency existed since original construction.

Enforcement. License Condition 2.E states, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described

in the Updated Final Safety Analysis Report through Amendment Number 55 for Unit 1,

the Updated Final Safety Analysis Report through Amendment Number 62 for Unit 2,

and the Fire Hazards Analysis Report through Amendment Number 23. Section 4.1 of

the Fire Hazards Analysis Report contains a comparison of the licensee's fire protection program to the requirements in 10 CFR Part 50, Appendix R. The Fire Hazards Analysis Report states that "fixed self-contained emergency lighting, consisting of sealed-beam

units with individual 8-hour minimum battery supply, will be provided in areas needed for

operation of hot standby/hot shutdown equipment, and in access and egress routes

thereto."

Contrary to the above, prior to February 9, 2017, the licensee failed to implement and maintain in effect all provisions of the approved fire protection program. Specifically, the licensee failed to provide 8-hour emergency lighting in all areas needed for operation of

hot standby/hot shutdown equipment.

10 The licensee entered this issue into their corrective action program as Condition

Report CR 17-1741. In addition to ensuring operators carried flashlights while on shift, the licensee also implemented a compensatory measure of adding flashlights to the procedure box in the essential cooling water intake Structure. 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 05000498/2017007-01; 05000499/2017007-01, "Failure to Provide 8-hour Emergency Lighting for All Alternative Shutdown Manual Actions."

.09 Cold Shutdown Repairs

a. Inspection Scope

South Texas Project Electric Generating Station has three trains of redundant equipment in each unit and, therefore, does not credit any cold shutdown repairs.

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.

For the train of systems necessary to achieve and maintain hot shutdown conditions, the team verified that the licensee treated these manual actions as compensatory measures while appropriate corrective actions are implemented or while preparations are made by the licensee to submit exemptions or deviations. For components important to safe shutdown that could adversely affect the safe shutdown capability, the team verified that

operators could reasonably be expected to perform the actions within the applicable

shutdown time requirements.

11 b. Findings

No findings were identified.

.11 Review and Documentation of Fire Protection Program Changes

a. Inspection Scope

The team reviewed changes made to the approved fire protection program since September 25, 2014. 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 the potential loss of large areas of the plant due to

explosions or fire as required by 10 CFR 50.54(hh)(2).

The team verified that the licensee implemented and maintained adequate procedures, maintained and tested equipment necessary to properly implement the strategies, and

ensured 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 on-site vehicles capable of towing the portable pump. The team assessed the off-site ability to obtain fuel for the portable pump and foam used for

firefighting efforts. The strategy and procedure selected for this inspection sample

included:

12 * Procedure 0POP10-FP-0001, "Alternate Fire Protection System Operation,"

Revision 4

One mitigating strategy sample was completed.

b. Findings

No findings were identified.

4. OTHER ACTIVITIES [OA]

4OA2 Problem Identification and Resolution (71152)

Corrective Actions for Fire Protection Deficiencies

a. Inspection Scope

The team selected a sample of condition reports associated with the licensee's fire

protection program to verify that the licensee had an appropriate threshold for identifying

deficiencies. The team reviewed the corrective actions proposed and implemented to verify that they were effective in correcting identified deficiencies. The team evaluated the quality of recent engineering evaluations through a review of condition reports,

calculations, and other documents during the inspection.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit

Exit Meeting Summary

On February 9, 2017, the team presented the inspection results to Mr. G. Powell, Executive

Vice President and Chief Nuclear Officer, and other members of the licensee staff. The

licensee acknowledged the findings presented.

The team verified that no proprietary information was retained by the team members or documented in this report.
