SUMMARY

IR 05000483/2016001; 01/01/2016

- 03/31/2016; Callaway Plant

, Flood Protection Measures The inspection activities described in this report were performed between January and March 31, 2016, by the resident inspectors at the Callaway Plant and inspectors from the NRC's Region IV office

. One finding of very low safety significance (Green) is documented in this report. This finding involved a violation of NRC requirements. The significance of inspection findings is indicated by their color (Green, White, Yellow, or Red), which is determined using Inspection Manual Chapter 0609, "Significance Determination Process." Their cross-cutting aspects are determined using Inspection Manual Chapter 0310, "Aspects within the Cross-Cutting Areas." Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy.

The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG

-1649, "Reactor Oversight Process."

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to perform an adequate operability determination for safety related components located in the 1988 foot auxiliary building train B piping penetration room (room 1203) based on degraded internal flooding drain capability. Specifically, the immediate operability determination included incorrect assumptions that were not verified to support th e operability determination as required by Procedure ODP-ZZ-00001, Addendum 15, "Operability and Functionality Determinations

," Revision 8. The immediate corrective action was to implement a compensatory measure to support operability of the equipment in room 1203. The issue was place d in the corrective action program as Callaway Action Request 201601412.

The licensee's failure to verify assumptions used in the immediate operability determination and ensure a sound basis for operability exists per plant procedures was a performance deficiency. The performance deficiency is more than minor, and therefore a finding, because it is similar to examples 3.j and 3.k in Inspection Manual Chapter 0612, Appendix E, "Examples of Minor Issues," and if left uncorrected, it has the potential to lead to a more significant safety concern. Specifically, failure to perform adequate operability evaluations by verifying assumptions and ensuring a sound basis for operability exists may result in the failure to enter the appropriate limiting conditions of operation for technical specification equipment.

Using Inspection Manual Chapter 0609, Appendix A, Exhibit 2, "Mitigating Systems Screening Questions," the finding involved the degradation of equipment specifically designed to mitigate a flooding initiating event, therefore,

Exhibit 4, "External Events Screening Questions," was used to complete the screening. The finding was determined to need a detailed risk evaluation because if the equipment (i.e.

, floor drain lines) is assumed to be completely failed or unavailable, it would degrade one or more trains of a system that supports a risk significant system or function. In consultation with the Senior Reactor Analyst, the finding was determined to be of very low safety significance because, based on the actual condition of the drains and the extent of the clogging in room 1203, an evaluation by the licensee showed that the maximum internal flooding water level in the room would not challenge the operability of any equipment needed for safe shutdown or to mitigate an accident. This finding has a team work cross-cutting aspect in the human performance cross-cutting area because individuals and work groups did not communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety is maintained.

Specifically, inadequate communication between engineering and operations personnel led to the belief that a passageway existed between rooms 1203 and 1204 when it did not

[H.4]. (Section 1R06)

PLANT STATUS

1R05 Fire Protection

.1 Quarterly Inspection

a. Inspection Scope

The inspectors evaluated the licensee's fire protection program for operational status and material condition. The inspectors focused their inspection on five plant areas important to safety:

January 6, 2016, train A spent fuel pool heat exchanger room (room 6105) and electrical equipment room (room 6202) in fuel building fire area (FB

-1) January 27, 2016, train B essential service water pump room (USPH)

January 27, 2016, upper cable spreading room (C

-22) January 27, 2016, lower cable spreading room (C

-21) March 22, 2016, train B class 1E air conditioning equipment room (C

-13) For each area, the inspectors evaluated the fire plan against defined hazards and defense-in-depth features in the licensee's fire protection program. The inspectors evaluated control of transient combustibles and ignition sources, fire detection and suppression systems, manual firefighting equipment and capability, passive fire protection features, and compensatory measures for degraded conditions.

These activities constituted fi ve quarterly inspection samples, as defined in Inspection Procedure 71111.05.

b. Findings

Introduction.

The inspectors identified an unresolved item associated with the National Fire Protection Association (NFPA) Standard 805, "Performance

-Based Standard for Fire Protection for Light

-Water Reactor Electric Generating Plants," non-power operations assessment. Specifically, the inspectors developed an issue of concern in that the licensee screened the potential loss of spent fuel pool cooling from further consideration for any fire event based on adequate procedural guidance and time when the procedures would not maintain the fuel in a safe and stable condition.

Description.

On January 13, 2014, the licensee transitioned their fire protection program to a risk-informed, performance

-based program based on NFPA Standard 805, "Performance

-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants

."

Paragraph 1.3.1 of NFPA Standard 805 requires licensees to provide reasonable assurance that a fire during any operational mode and plant configuration will not prevent the plant from achieving and maintaining the fuel in a safe and stable condition.

Paragraph 1.5.1 of NFPA Standard 805 lists five nuclear safety performance criteria. These criteria provide requirements to demonstrate that fire protection features are capable of providing reasonable assurance that the plant is not placed in an unrecoverable condition in the event of a fire. For the decay heat removal nuclear safety performance criterion, the standard requires that decay heat removal shall be capable of removing sufficient heat from the reactor core or spent fuel such that fuel is maintained in a safe and stable condition.

Paragraph 1.6.56 of NFPA Standard 805 defines safe and stable conditions:

For fuel in the reactor vessel, head on and tensioned, safe and stable conditions are defined as the ability to maintain Keff <0.99, with a reactor coolant temperature at or below the requirements for hot shutdown for a boiling water reactor and hot standby for a pressurized water reactor. For all other configurations, safe and stable conditions are defined as maintaining Keff <0.99 and fuel coolant temperature below boiling.

The licensee described how they satisfied the nuclear safety performance criteria in Calculation KC-26, "Nuclear Safety Capability Assessment," Revision 1. The Nuclear Safety Capability Assessment applied to both power and non

-power operations.

For non-power operations, the licensee evaluated the spent fuel pool decay heat removal key safety function and determined that t he spent fuel pool decay heat removal key safety function did not require a detailed review since adequate time was available, and procedural guidance was provided, for operators to respond to and mitigate a loss of spent fuel pool decay heat removal, even under full hot core offload conditions.

The licensee stated that the shortest time to boil, under worst case conditions for a normal plant shutdown, was two hours. In addition, the licensee stated that all of the analyses to address a loss of spent fuel pool decay heat removal utilized a success criterion of no boiling.

The licensee implemented the process outlined in Frequently Asked Question (FAQ) 07-0040, "Non

-Power Operations Clarifications," Revision 4, for the non-power operations assessment.

This FAQ stated that licensees should conservatively assume the entire contents of a fire area are lost and document the loss of success paths. This FAQ also stated that licensees should specifically identify those areas (pinch points)that cause the loss of all success paths for a key safety function.

The inspectors noted that the licensee did not perform these actions for the spent fuel pool decay heat removal key safety function because this key safety function was screened out from further consideration. If the licensee had evaluated the spent fuel pool decay heat removal key safety function using the process outlined in this FAQ, then the licensee would have assumed that both trains of spent fuel pool cooling are lost during a fire in the fuel handling building because both trains are located within the same fire area and were unprotected.

This FAQ also stated that fire modeling may be used to determine if postulated fires in a fire area are expected to damage equipment (and cabling), thereby eliminating a pinch point. However, the licensee stated that no fire modeling was used to eliminate the identification of pinch point fire areas as part of the non

-power operations assessment performed using the process in FAQ 07-0040.

In the event that a fire in the fuel handling building disabled both trains of spent fuel pool cooling, operators were expected to enter Procedure OTO-EC-00002, "Spent Fuel Pool High Temperature," Revision 9, due to the increasing temperature of the spent fuel pool.

This procedure provided directions for operators to restore one or both trains of spent fuel pool cooling. Since both trains of spent fuel pool cooling were assumed lost due to the fire, the operators would be unable to restore spent fuel pool cooling using this procedure.

After a period of time, the spent fuel pool would begin boiling and the level would begin lowering. At this time, operators were expected to enter Procedure OTO-EC-00001, "Loss of SPF/Refuel Pool Level," Revision 13. Procedure OTO-EC-00001 directed the operators to open two normally locked essential service water valves to restore and maintain spent fuel pool level.

The licensee's procedures allowed the spent fuel pool to reach boiling conditions prior to restoring and maintaining level. Since NFPA Standard 805 defined safe and stable conditions, in part, as fuel coolant temperature below boiling, the procedures did not maintain the fuel in a safe and stable condition. The inspectors identified an issue of concern in that the licensee screened the potential loss of spent fuel pool cooling from further consideration for any fire event based on adequate procedural guidance and time when the procedures would not maintain the fuel in a safe and stable condition.

The inspectors determined that additional information is required to determine if a performance deficiency exists. Specifically, the inspectors need to determine if this scenario should have been addressed as part of the current FAQ 07-0040 guidance, or if new guidance is needed to address this type of scenario where the full core has been offloaded to the spent fuel pool.

On March 31, 2016, additional guidance was requested from the Office of Nuclear Reactor Regulation via a request to review and update FAQ 07-0040. This memorandum is documented in ADAMS as Accession Number ML16091A152.

The licensee entered this issue of concern into the corrective action program as Callaway Action Request 201600726. This issue of concern is being treated as Unresolved Item 05000483/

2016001-01, "Possible Incorrect Screening of the Spent Fuel Pool Decay Heat Removal Key Safety Function.

"

.2 Annual Inspection

a. Inspection Scope

On March 2, 2016, the inspectors completed their annual evaluation of the licensee's fire brigade performance. This evaluation included observation of an announced fire drill for a fire in the laundry decontamination facility.

During this drill, the inspectors evaluated the capability of the fire brigade members, the leadership ability of the brigade leader, the brigade's use of turnout gear and fire

-fighting equipment, and the effectiveness of the fire brigade's team operation. The inspectors also reviewed whether the licensee's fire brigade met NRC requirements for training, dedicated size and membership, and equipment.

These activities constituted one annual inspection sample, as defined in Inspection Procedure 71111.05.

b. Findings

No findings were identified.

1R06 Flood Protection Measures

a. Inspection Scope

On February 18, 2016, the inspectors completed an inspection of the station's ability to mitigate flooding due to internal causes. After reviewing the licensee's flooding analysis, the inspectors chose the auxiliary building 1988 foot elevation containing risk

-significant structures, systems, and components that were susceptible to flooding.

The inspectors reviewed plant design features and licensee procedures for coping with internal flooding. The inspectors walked down the selected areas to inspect the design features, including the material condition of seals, drains, and flood barriers. The inspectors evaluated whether operator actions credited for flood mitigation could be successfully accomplished.

These activities constitute d completion of one flood protection measures sample, as defined in Inspection Procedure 71111.06.

b. Findings

Introduction

. The inspectors identified a Green, non

-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to perform an adequate operability determination for safety related components located in the 1988 foot auxiliary building train B piping penetration room (room 1203) based on degraded internal flooding drain capability. Specifically, the immediate operability determination (IOD) included incorrect assumptions that were not verified to support the operability determination as required by licensee Procedure ODP-ZZ-00001, Addendum 15, "Operability and Functionality Determinations

," Revision 8. Description

. On July 2, 2014, during a planned maintenance inspection of 6 of the 12 floor drain lines in room 1203, one floor drain line was found to be approximately 50 percent clogged.

Drain lines in room 1203 are credited in Calculation M-FL-03, "Flooding of Individual Aux Building Rooms," to provide sufficient water removal capability during an internal flooding event. An IOD was completed which credited a 2-foot wide passage between room 1203 and the 1988 foot elevation auxiliary building train A piping penetration room (room 1204). With a passage between the rooms, any water from an internal flooding event in room 1203 would flow to room 1204 where the drain lines in that room would be able to make up for the flow loss from the clogged drain line in room 1203. On August 21, 2014, four additional floor drains of the remaining six drain lines in room 1203 were discovered to be partially blocked.

One of these drains was able to be cleared during the inspection.

The three additional clogged drain lines further reduced the ability for water to drain out of room 1203 during an internal flooding event. These clogged drains were documented in two separate Callaway action requests and two new IODs were performed. The IODs determined that the equipment in room 1203 remained operable based on a 2-foot 8-inch opening in the wall connecting rooms 1203 and 1204. With this opening present, the seven drain lines in room 1204 were credited to remove water. On October 12, 2015, one of clogged drains in room 1203 was cleared during maintenance.

Upon review by inspectors on February 18, 2016, a visual inspection showed that the 2-foot 8-inch opening was not actually present in the wall between rooms 1203 and 1204. A fourth IOD was conducted at that time and a compensatory measure was implemented to open the access door to room 1203 to allow a drainage path for water out of the room during an internal flooding event.

Subsequent analysis of past operability was conducted and determined that an internal flooding event in room 1203 would not affect the operability of safety related components within or outside the room.

Architectural drawing A-2305, "Auxiliary and Reactor Building Floor Plans, El.

1988'-0" & El. 2013'-6"," shows the 2-foot 8-inch opening between rooms 1203 and 1204. This drawing was referenced in the initial IOD. The initial IOD states that the 2-foot wide passage between rooms 1203 and 1204 was confirmed by operations walk

-down. The licensee's causal analysis determined that a walk

-down was completed in the rooms, however, operations believed that a 13-inch piping penetration hole between the rooms was the opening that was being referred to.

This was due to a communications error between engineering and operations.

Drawing C-2C11231, "Auxiliary Building Concrete Neat Lines Plan Floor El.

1988'-0"," shows the 2-foot 8-inch opening as an "optional opening." This drawing is referenced in the subsequent IODs.

Walk-downs were not completed during the subsequent IODs based on the statement in the original IOD that this opening was verified at that time.

Procedure ODP-ZZ-00001, Addendum 15, states that "The SM should ENSURE an appropriate level of questioning and challenging of assumptions occurs to ensure that a sound basis for operability exists throughout the OD process."

In this case, because the wall opening between rooms 1203 and 1204 was credited in the IODs conducted for the degraded drain capability in room 1203 and did not actually exist, a sound basis for operability did not exist throughout the operability determination process.

Analysis.

The licensee's failure to verify assumptions used in the IOD and ensure a sound basis for operability exists per plant procedures was a performance deficiency.

The performance deficiency is more than minor, and therefore a finding, because it is similar to examples 3.j and 3.k in Inspection Manual Chapter 0612, Appendix E, "Examples of Minor Issues," and if left uncorrected, it has the potential to lead to a more significant safety concern. Specifically, failure to perform adequate operability evaluations by verifying assumptions and ensuring a sound basis for operability exists may result in the failure to enter the appropriate limiting conditions of operation for technical specification equipment.

Using Inspection Manual Chapter 0609, Appendix A, Exhibit 2, "Mitigating Systems Screening Questions," the finding involved the degradation of equipment specifically designed to mitigate a flooding initiating event, therefore, Exhibit 4, "External Events Screening Questions," was used to complete the screening

. The finding was determined to need a detailed risk evaluation because if the equipment (i.e.

, floor drain lines) were assumed to be completely failed or unavailable, it would degrade one or more trains of a system that supports a risk significant system or function. In consultation with the Senior Reactor Analyst, the finding was determined to be of very low safety significance because, based on the actual condition of the drains and the extent of the clogging in room 1203, an evaluation by the licensee showed that the maximum internal flooding water level in the room would not challenge the operability of any equipment needed for safe shutdown or to mitigate an accident. This finding has a teamwork cross-cutting aspect in the human performance cross

-cutting area because individuals and work groups did not communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety is maintained.

Specifically

, inadequate communication between engineering and operations personnel led to the belief that a passageway existed between rooms 1203 and 1204 when it did not

[H.4].

Enforcement

. Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality shall be accomplished in accordance with instructions, procedures, or drawings of a type appropriate to the circumstances.

Callaway Procedure ODP-ZZ-00001, Addendum 15, "Operability and Functionality Determinations

," an Appendix B quality related procedure, provides instructions for performing operability determinations.

Procedure ODP-ZZ-00001, Addendum 15, step 3.2.2 states, in part

, "The SM should ENSURE an appropriate level of questioning and challenging of assumptions occurs to ensure that a sound basis for operability exists throughout the OD process." Contrary to the above, on July 2 and August 21, 2014, the licensee failed to ensure an appropriate level of questioning and challenging of assumptions occurred to ensure that a sound basis for operability existed throughout the operability determination process.

Specifically, the licensee credited, in an operability determination, an opening in the wall between rooms 1203 and 1204 that did not exist. The immediate corrective action was to implement a compensatory measure to support operability of the equipment in room 1203. This violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy. The violation was entered into the licensee's corrective action program as Callaway Action Request 201601412

.2 Review of Licensed Operator Performance

a. Inspection Scope

During the period, the inspectors observed the performance of on

-shift licensed operators in the plant's main control room. At the time of the observations, the plant was in a period of heightened activity due to the activities listed below.

The inspectors observed the operators' performance of the following activities:

February 17, 2016, reactor coolant pump undervoltage and underfrequency relay testing and train B centrifugal charging pump in

-service testing February 19, 2016, control room turnover In addition, the inspectors assessed the operators' adherence to plant procedures, including Procedure ODP-ZZ-00001, "Operations Department

- Code of Conduct,"

Revision 97, and other operations department policies.

These activities constitute d completion of one quarterly licensed operator performance sample, as defined in Inspection Procedure 71111.11.

b. Findings

No findings were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

The inspectors reviewed two instances of degraded performance or condition of safety-related structures, systems, and components

February 12, 2016, reactor coolant system 10 CFR 50.65(a)(1) evaluation February 26, 2016, component cooling water The inspectors reviewed the extent of condition of possible common cause structure, system, or component failures and evaluated the adequacy of the licensee's corrective actions. The inspectors reviewed the licensee's work practices to evaluate whether these may have played a role in the degradation of the structures, systems, or components. The inspectors assessed the licensee's characterization of the degradation in accordance with 10 CFR 50.65 (the Maintenance Rule), and verified that the licensee was appropriately tracking degraded performance and conditions in accordance with the Maintenance Rule.

These activities constituted completion of two maintenance effectiveness sample s, as defined in Inspection Procedure 71111.12.

b. Findings

No findings were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control

(71111.13)

a. Inspection Scope

The inspectors reviewed two risk assessments performed by the licensee prior to changes in plant configuration and the risk management actions taken by the licensee in response to elevated risk:

January 26, 2016, train A motor-driven auxiliary feedwater pump planned maintenance March 3, 2016, train B air compressor and service water pump planned maintenance The inspectors verified that these risk assessment were performed timely and in accordance with the requirements of 1 0 CFR 50.65 (the Maintenance Rule) and plant procedures. The inspectors reviewed the accuracy and completeness of the licensee's risk assessments and verified that the licensee implemented appropriate risk management actions based on the result of the assessments. The inspectors also observed portions of three emergent work activities that had the potential to cause an initiating event, to affect the functional capability of mitigating systems, or to impact barrier integrity:

March 2, 2016, train B component cooling water isolation valve to rad waste stroke time test failure and repair March 9, 2016, train B emergency diesel generator digital reference unit issue March 21, 2016, loop 4 over temperature delta

-T spiking low The inspectors verified that the licensee appropriately developed and followed a work plan for these activities. The inspectors verified that the licensee took precautions to minimize the impact of the work activities on unaffected structures, systems, and components

.

These activities constitute d completion of five maintenance risk assessments and emergent work control inspection samples, as defined in Inspection Procedure 71111.13.

b. Findings

4OA3 Follow-up of Events and Notices of Enforcement Discretion

1. (Closed) Licensee Event Report 2015-003-00 and 2015-003-01, Reactor Trip Caused by Transmission Line Fault

On August 11, 2015, the reactor tripped from 10 0 percent power due to an incorrect, automatic response to a transmission line fault on the Montgomery

-Callaway 8 line by transformer bus differential relaying. This resulted in reactor protection system and auxiliary feedwater system actuations. The plant response was as expected except for problems with auxiliary feedwater system flow control valve (ALHV007) subsequent to the plant trip

. The problems with ALHV007 were the subject of a special inspection and were dispositioned in NRC Inspection Report 05000483/2015009 (ADAMS Accession Number ML16013A021

). This event was caused by the inadvertent inclusion of jumpers in the current transformer circuits of the main transformers that were installed as part of a plant modification during Refueling Outage 19. Following the event, the licensee corrected the condition by removing the errantly installed current transformer jumper s and then restarted the plant.

The licensee determined the root cause of the incorrect main transformer current transformer wiring was that a drawing, which originally depicted the installation of the jumpers, was not revised when converted from a vendor drawing to a licensee controlled drawing in 1983. Given that this error occurred prior to the Callaway Plant receiving an operating license, the inspectors determined that a performance deficiency reasonably within the licensee's control to prevent did not exist.

Additional corrective actions included additional design, testing, and job reviews, as well as reviews of similar vendor generated drawings to determine the extent of cause and condition.

No violation of NRC requirements were identified. This licensee event report is closed.

2. (Closed) Licensee Event Report 2015-004-00, Auxiliary Feedwater Flow Control Valve Inoperable due to Faulty Electronic Positioner Card On August 11, 2015, the licensee determined that a latent problem in the auxiliary feedwater system led to a condition prohibited by technical specifications and could have prevented the fulfillment of a safety function. Specifically, the condition was a flawed card used in the flow control valve for motor

-driven auxiliary feedwater pum p B combined with planned work outages for redundant trains of auxiliary feedwater. The licensee believed t hese condition s existed for short durations between November 18 and December 3, 2014. This issue was the subject of a special inspection

, and all related findings were dispositioned in NRC Inspection Report 05000483/2015009 (ADAMS Accession Number ML16013A021

). This licensee event report is closed.

These activities constitute d completion of t wo event follow

-up samples, as defined in Inspection Procedure 71153.
