SUMMARY OF FINDINGS

IR 05000259/2012003, 05000260/2012003, 05000296/2012003, 05000259/2012502,

05000260/2012502, 05000296/2012502; 04/01/2012 -06/30/2012; Browns Ferry Nuclear Plant,

Units 1, 2 and 3; Operability Evaluations, Radioactive Solid Waste Processing and Radioactive

Material Handling, Storage, and Transportation, and Event Follow-Up.

The report covered a three month period of inspection by resident and regional inspectors. Four

findings were identified. The significance of most findings is identified by their color (Green,

White, Yellow, and Red) using Inspection Manual Chapter (IMC) 0609, Significance

Determination Process (SDP); and, the cross-cutting aspects were determined using IMC

0310, Components Within the Cross-Cutting Areas. Findings for which the SDP does not

apply may be Green or be assigned a severity level after NRC management review. The NRCs

program for overseeing the safe operation of commercial nuclear power reactors is described in

NUREG-1649, Reactor Oversight Process Revision 4, dated December 2006.

NRC Identified and Self-Revealing Findings

Cornerstone: Initiating Events

Green. A self-revealing finding (FIN) was identified for the licensees failure to

perform preventive maintenance on the Unit 3 Main Control Room (MCR)

annunciator power supplies. As a result, a power supply failed which led to a fire in

annunciator panel 3-X-55-5A in the Unit 3 control room. The licensee initiated

actions to extinguish the fire, replace the two affected power supplies and develop a

preventive maintenance program to replace the power supplies every ten years.

Additional corrective actions to replace all power supplies that have been installed for

more than four years are pending. This was captured in the licensees corrective

action program as problem event report (PER) 496592.

The performance deficiency was determined to be more than minor because it was

considered sufficiently similar to example 4.f of Inspection Manual Chapter (IMC)

0612, Appendix E, for an issue that resulted in a fire hazard in a safety-related area

of the plant. The finding was associated with the Initiating Events Cornerstone and

required a phase 3 analysis in accordance with IMC 0609 because the finding

increased the likelihood of, and actually caused, a fire in the Unit 3 control room.

The phase 3 analysis determined that without an impact to additional plant

equipment, or a major impact on human action failure rates, the finding was

determined to be Green. The cause of this finding was related to the cross cutting

aspect of Problem Identification in the Corrective Action Program component of the

Problem Identification and Resolution area because the licensee should have

recognized the electrolytic capacitors were installed beyond their recommended

service life and scheduled replacement prior to their failure P.1(a). (Section

4OA3.6)

3

Enclosure

Cornerstone: Mitigating Systems

Green. An NRC-identified non-cited violation (NCV) of the Technical Specifications

5.4.1.a was identified for the licensees failure to maintain an Emergency Equipment

Cooling Water (EECW) pump flood barrier in accordance with written procedures

which resulted in the inoperability of two other safety related pumps. The licensee

immediately restored the flood protection configuration of the C Residual Heat

Removal Service Water (RHRSW) pump room by properly re-installing the flood

protection cover and permanently stenciled the aluminum plate with the required

procedure for installation. The licensee entered this issue into their corrective action

program as PER 532050.

The finding was more than minor because it was associated with the Mitigating

Systems cornerstone attribute of Protection Against External Events, and adversely

affected the cornerstone objective to ensure the availability, reliability, and capability

of RHRSW pumps to perform their intended safety function during a design basis

flooding event. Specifically, the improper re-installation of an external flood

protection cover resulted in the inoperability of two Residual Heat Removal Service

Water (RHRSW) pumps. The significance of this finding was evaluated in

accordance with the IMC 0609 Attachment 4, Phase 1- Initial Screening and

Characterization of Findings, which required a Phase 3 analysis because the finding

involved the degradation of equipment designed to mitigate a flooding event and it

was risk significant due to external initiating event core damage sequences. The

finding was determined to be Green because of the short exposure time, and the low

likelihood of the flood. The cause of this finding was directly related to the cross

cutting aspect of Supervisory Oversight in the Work Practices component of the

Human Performance area, because of the foremans assumption that workers knew

to restore the flood protection cover to meet procedural requirements without a

formal pre-job brief H.4(c). (Section 1R15)

Cornerstone: Public Radiation Safety

Green. A self-revealing non-cited violation (NCV) of 10 CFR 71.5, Transportation of

Licensed Material, was identified by inspectors for the licensees failure to comply

with Department of Transportation (DOT) regulations during shipment of radioactive

materials. Specifically, the licensee failed to ensure proper packaging of two DOT 7A

Type A packages as required by Department of Transportation (DOT) regulations in

49 CFR 173.475, Quality Control Requirements Prior To Each Shipment Of Class 7

(Radioactive) Materials. This issue has been entered into the licensees corrective

action program as SR 570902.

The finding was more than minor because it is associated with the Public Radiation

Safety Cornerstone, Plant Facilities/Equipment and Instrumentation attribute,

involving transportation packaging and adversely affected the cornerstone objective,

to ensure adequate protection of public health and safety from exposure to

radioactive materials released into the public domain as a result of routine civilian

nuclear reactor operation. Specifically, the failure to correctly secure the package

4

Enclosure

contents to prevent movement could have resulted in damage or failure of the

container during transportation. The finding was determined to be of very low safety

significance (Green) because it did not involve radiation limits being exceeded, a

package breach, a certificate of compliance issue, a low-level burial ground non-

conformance, or a failure to make emergency notifications. The cause of this finding

was directly related to the cross cutting aspect of Documents, Procedures and

Component Labeling in the Resources component of the Human Performance area

because the licensee did not effectively incorporate package design specifications

into their transportation program to ensure that all internal restraining devices are

correctly installed to secure the CRDM in place to prevent damage to the transport

package. (H.2(c)) (Section 2RS8)

Green. A self-revealing non-cited violation (NCV) of 10 CFR 71.5, Transportation of

Licensed Material, was identified by inspectors for the licensees failure to comply

with Department of Transportation (DOT) regulations during shipment of radioactive

materials. Specifically, the licensee failed to ensure proper closure of a DOT 7A Type

A package as required by Department of Transportation (DOT) regulations in 49

CFR 173.475, Quality Control Requirements Prior To Each Shipment Of Class 7

(Radioactive) Materials. This issue has been entered into the licensees corrective

action program as SR 571151.

The finding was more than minor because it is associated with the Public Radiation

Safety Cornerstone, Plant Facilities/Equipment and Instrumentation attribute,

involving transportation packaging and adversely affected the cornerstone objective,

to ensure adequate protection of public health and safety from exposure to

radioactive materials released into the public domain as a result of routine civilian

nuclear reactor operation. Specifically, the failure to apply the correct torque to the

package closure bolts could have resulted in incomplete sealing of the container or

failure of the cover bolts during transportation. The finding was determined to be of

very low safety significance (Green) because it did not involve radiation limits being

exceeded, a package breach, a certificate of compliance issue, a low-level burial

ground non-conformance, or a failure to make emergency notifications. The cause

of this finding was directly related to the cross cutting aspect of Documents,

Procedures and Component Labeling in the Resources component of the Human

Performance area because the licensee did not effectively incorporate the vendor

provided container loading and shipping instructions into their work package and

transportation program to ensure correct torque values were used to close the

shipping container. (H.2(c)) (Section 2RS8).

REPORT DETAILS

Summary of Plant Status

Unit 1 operated at full power for most of the report period except for an unplanned downpower

on June 29, 2012, to 75 percent power to reduce load on the B Phase Main Bank Transformer

due to a lifting oil pressure relief. The unit returned to full power on June 30, 2012.

Unit 2 operated at full power for most of the report period except for one planned and one

unplanned downpower. On April 20, 2012, the unit performed a planned downpower to 66

percent power for rod pattern adjustment, scram time testing and turbine valve testing. The unit

returned to full power on April 22nd. On May 15, 2012, the unit performed an unplanned

downpower to 92 percent power to insert control rod 30-51 for scram outlet valve repair and

returned to full power the same day.

Unit 3 operated at full power for most of the report period except for one planned downpower,

one manual and two automatic scrams, and one unplanned downpower. On April 6, 2012, the

unit was shutdown for a scheduled refueling outage that lasted 49 days. The unit was restarted

on May 19th. On May 22nd, an automatic scram occurred from 19.5 percent power with the

main turbine generator offline due to a 3A Unit Station Service Transformer differential relay trip

caused by incorrect relay setting. On May 24, 2012, during reactor startup and heatup an

unplanned manual scram occurred as a result of a partial control rod insertion caused by a

combination of a signal spike and an inappropriate operator downrange on separate

intermediate power range monitors. The unit restarted the same day. On May 29, 2012, a main

generator current transformer manufactured and installed with reverse polarity caused an

automatic scram from 75 percent power. The unit restarted on June 2nd and returned to full

power on June 5th. On June 6th, the unit performed an unplanned downpower from 96 percent

power to 75 percent power to remove the 3B condensate booster pump with high moisture in its

oil system from service. The unit returned to full power on June 8, 2012.

The inspectors examined activities associated with Unit 3 RHR Heat Exchangers. The

inspectors also reviewed design basis documents, calculations, test procedures,

maintenance procedures and preventive maintenance procedures and results to

evaluate the licensees program for maintaining heat sinks in accordance with the

licensing basis. Specifically inspectors reviewed modifications performed on the Unit 3

RHR Heat Exchanger Flanges. Inspectors reviewed available performance testing

documentation of the 3A and 3C RHR Heat Exchangers.

In addition, the inspectors reviewed the licensees implementation of the GL 89-13

program. Inspectors reviewed associated PERs and corrective actions to verify that the

licensee was identifying issues and correcting them. The inspectors performed

walkdowns of key components of the Unit 3 RHR system to verify material conditions

were acceptable and physical arrangement matched procedures and drawings. This

activity constituted one Annual Heat Sink sample.

1R08 Inservice Inspection (ISI) Activities (71111.08G, Unit 3)

a.

Inspection Scope

Non-Destructive Examination (NDE) Activities and Welding Activities: From April 16 to

April 20, 2012, the inspectors conducted an on-site review of the implementation of the

licensees Inservice Inspection (ISI) Program for monitoring degradation of the reactor

coolant system, emergency feedwater systems, risk-significant piping and components,

and containment systems in Unit 3. The inspectors activities included a review of non-

destructive examinations (NDEs) to evaluate compliance with the applicable edition of

the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel

Code (BPVC),Section XI (Code of record: 2001 Edition with 2003 Addenda), and to

verify that indications and defects (if present) were appropriately evaluated and

dispositioned in accordance with the requirements of the ASME Code,Section XI,

acceptance standards.

The inspectors directly observed the following NDE mandated by the ASME Code to

evaluate compliance with the ASME Code Section XI and Section V requirements and, if

any indications and defects were detected, to evaluate if they were dispositioned in

accordance with the ASME Code or an NRC-approved alternative requirement.

inspectors reviewed the work order, repair and replacement plan, weld data sheets,

welding procedures, procedure qualification records, welder performance qualification

records, and NDE reports.

Work Order 04-719493-003, 3-FCV-073-016 HPCI Turbine Steam Supply Valve

Work Order 08-718716-004, Replace Strain Gauges on MS Lines

During non-destructive surface and volumetric examinations performed since the

previous refuelling outage, the licensee did not identify any relevant indications that were

analytically evaluated and accepted for continued service. Therefore, no NRC review

was completed for this inspection procedure attribute.

Identification and Resolution of Problems: The inspectors performed a review of a

sample of ISI-related problems which were identified by the licensee and entered into

the corrective action program as Problem Evaluation Reports (PERs). The inspectors

reviewed the PERs to confirm the licensee had appropriately described the scope of the

problem, and had initiated corrective actions. The review also included the licensees

consideration and assessment of operating experience events applicable to the plant.

The inspectors performed this review to ensure compliance with 10 CFR Part 50,

Appendix B, Criterion XVI, Corrective Action, requirements. The corrective action

documents reviewed by the inspectors are listed in the report attachment.

1R11 Licensed Operator Requalification

.1

Resident Inspector Quarterly Review

a.

Inspection Scope

On June 11, 2012, the inspectors observed an as-found licensed operator requalification

simulator examination according to Unit 2 Simulator Exercise Guide OPL173.S039. The

scenario involved Partial Loss of Reactor Building Closed Cooling Water, Loss of I & C

Bus B, Anticipated Transient without Scram (ATWS), Lower Water Level (C-5) for Power

Control with Bypass Valves.

The inspectors specifically evaluated the following attributes related to the operating

crews performance:

Clarity and formality of communication

Ability to take timely action to safely control the unit

Prioritization, interpretation, and verification of alarms

Correct use and implementation of Abnormal Operating Instructions (AOIs), and

Emergency Operating Instructions (EOIs)

Timely and appropriate Emergency Action Level declarations per Emergency Plan

Implementing Procedures (EPIP)

Control board operation and manipulation, including high-risk operator actions

Command and Control provided by the Unit Supervisor and Shift Manager

The inspectors attended the post-examination critique to assess the effectiveness of the

licensee evaluators and to verify that licensee-identified issues were comparable to

issues identified by the inspector. The inspectors reviewed simulator physical fidelity

(i.e., the degree of similarity between the simulator and the reference plant control room,

such as physical location of panels, equipment, instruments, controls, labels, and related

form and function). This activity counts for one Observation of Requalification Activity

inspection sample.

b.

Findings

No findings were identified.

Findings

Two findings were identified. One finding is documented as a licensee identified violation

in Section 4OA7.

1) Introduction: The NRC identified a Green non-cited violation (NCV) of Technical

Specification 5.4.1.a for the licensees failure to maintain an Emergency Equipment

Cooling Water (EECW) pump flood barrier in accordance with written procedures which

resulted in the inoperability of two other safety related pumps.

Description:

The safety related Residual Heat Removal Service Water (RHRSW) pumps are housed

in the A, B, C, and D rooms of the intake pumping station. UFSAR Section 12.2.7.1.1

states, in part, that each room is designed to protect the RHRSW pumps from water and

wave forces resulting from a probable maximum flood (PMF) scenario. During

14

Enclosure

maintenance activities, the licensee maintained the design flood protection configuration

through implementation of properly written work instructions.

The C3 Emergency Equipment Cooling Water (EECW) pump is located in the C

RHRSW pump room with two similarly designed C1 and C2 RHRSW pumps. On March

26, 2012, the licensee had removed C3 pump from service for maintenance. The C3

pump and motor had been disassembled and the pump column removed from the intake

sump pit through the pump base plate and foundation leaving an approximate 22 inch

diameter hole. The hole was protected against flooding by a temporary 1/4 inch thick

aluminum cover plate, over a rubber gasket and secured with 8 foundation bolts. The

flood cover was prescribed by work order 112744581 and implemented by maintenance

procedures MCI-0-023-PMP002, Maintenance of EECW and RHRSW Pumps, and MCI-

0-023-PMP003, Emergency Equipment Cooling Water and Residual Heat Removal

Service Water Pump Removal and Installation.

On April 2, 2012, maintenance personnel removed the flood protection cover to facilitate

an inspection. Personnel re-installed the cover with only two bolts and nuts run down to

approximately one inch from being fully secured. On April 5, 2012, inspectors identified

and informed the licensee of the inadequate flood protection barrier. The licensee

immediately re-installed the flood protection cover in accordance with maintenance

procedures. As an added corrective action, the licensee permanently stenciled the

aluminum plate with the required procedure for installation. The licensee determined

that the workers had re-installed the flood protection cover following the inspection

assuming that it was only for foreign material exclusion. The licensee also determined

that the foreman did not direct an adequate pre-job brief and assumed the workers knew

of the procedural flood requirements. Furthermore, the licensee evaluated the

inadequate flood barrier for past operability and concluded that the C RHRSW pump

room would have flooded in the event of a PMF and that the other two RHRSW pumps

in the room, C1 and C2, would be made nonfunctional. The licensee credited the slow

progression of a PMF flood rise (four days and eight hours) to allow time to adequately

install the flood protection cover, and therefore, prevent the loss of the RHRSW pumps.

These actions were contained in licensee abnormal operating instruction 0-AOI-100-3,

Flood Above Elevation 558.

Analysis: The licensees failure to maintain an Emergency Equipment Cooling Water

(EECW) pump flood barrier in accordance with written procedures was a performance

deficiency. The finding was more than minor because it was associated with the

Mitigating Systems cornerstone attribute of Protection Against External Events, and

adversely affected the cornerstone objective to ensure the availability, reliability, and

capability of RHRSW pumps to perform their intended safety function during a design

basis flooding event. Specifically, the improper re-installation of an external flood

protection cover resulted in the inoperability of two RHRSW pumps. The significance of

this finding was evaluated in accordance with the IMC 0609 Attachment 4, Phase 1-

Initial Screening and Characterization of Findings, which required a Phase 3 analysis

because the finding involved the degradation of equipment designed to mitigate a

flooding event and was risk significant due to external initiating event core damage

sequences. A Phase 3 SDP analysis was performed by the regional Senior Reactor

Analyst using a modified NRC plant model. The model had been modified to calculate

15

Enclosure

the impact on the plant from external flooding due to the failure of the RHRSW flood

doors. The plant model was solved for a loss of condenser heat sink, with the initiating

event frequency set to 5E-3 as a conservative estimate for the external flood. Also

assumed was the unavailability of the power conversion system, since the circ water

pumps, and their power supplies would be flooded. Condensate was assumed lost

when the turbine building floods. RHRSW pumps and EECW pumps in the flooded

RHRSW room were failed by model changes for different flood door failure basic events.

This analysis failed only the C room door, which duplicated the impact of an unsecured

flood barrier. For the 4 day exposure time, the result was several orders of magnitude

below the CDF or LERF threshold for a finding of significance. The finding is Green

because of the short exposure time, and the low likelihood of the flood.

The cause of this finding was directly related to the cross cutting aspect of Supervisory

Oversight in the Work Practices component of the Human Performance area, because of

supervisions assumption that workers knew to restore the flood protection cover to meet

procedural requirements without a formal pre-job brief H.4(c).

Enforcement: TS 5.4.1.a. required that written procedures recommended in RG 1.33,

Revision 2, Appendix A, shall be established, implemented, and maintained. Item 9.a of

RG 1.33, Appendix A, stated, in part, that maintenance affecting the performance of

safety-related equipment be properly performed in accordance with written procedures

or documented instructions appropriate to the circumstances. Contrary to the above,

between April 2, and April 5, 2012, the licensee failed to properly perform maintenance

procedures MCI-0-023-PMP002 and MCI-0-023-PMP003, Section 5.0.K. Specifically,

the licensee failed to maintain a flood barrier during maintenance on C3 EECW Pump

which resulted in the inoperability of C1 and C2 RHRSW Pumps. Because this finding is

of very low safety significance (Green) and because it was entered into the licensees

corrective action program as PER 532050, this violation is being treated as a non-cited

violation consistent with the NRC Enforcement Policy. This violation was applicable to

U1, U2 and U3 and is identified as NCV 05000259, 260, 296/2012003-01, Failure to

Maintain Flood Barrier Results in Inoperable Safety Related Pumps.

1R18 Plant Modifications

requirements were met, along with procedures, as applicable, such as NPG-SPP-9.3,

Plant Modifications and Engineering Change Control; NPG-SPP-9.5, Temporary

Alterations; and NPG-SPP-6.9.3, Post-Modification Testing. The inspectors also

reviewed the associated 10 CFR 50.59 screenings and evaluations and compared each

against the UFSAR and TS to verify that the modifications did not affect operability or

availability of the affected systems. Furthermore, the inspectors walked down each

modification to ensure that it was installed in accordance with the modification

documents and reviewed post-installation and removal testing to verify that the actual

impact on permanent systems was adequately verified by the tests. This activity

constituted two Plant Modification inspection samples.

1R20 Refueling and Other Outage Activities

.1

Unit 3 Scheduled Refueling Outage (U3R15)

a.

Inspection Scope

During April 7 to May 26, 2012, the inspectors examined critical outage activities to verify

that they were conducted in accordance with technical specifications, applicable

procedures, and the licensees outage risk assessment and management plans through

the end of the reporting period. Some of the more significant inspection activities

conducted by the inspectors were as follows:

Outage Risk Assessment

Prior to the Unit 3 scheduled 30 day U3C15 refueling outage that began on April 7, the

inspectors attended outage risk assessment team meetings and reviewed the Outage

Risk Assessment Report to verify that the licensee had appropriately considered risk,

industry experience, and previous site-specific problems in developing and implementing

an outage plan that assured defense-in-depth of safety functions were maintained. The

inspectors also reviewed the daily U3C15 Refueling Outage Reports, including the

Outage Risk Assessment Management (ORAM) Safety Function Status, and regularly

attended the twice a day outage status meetings. These reviews were compared to the

requirements in licensee procedure NPG-SPP-07.2, Outage Management, and technical

specifications. These reviews were also done to verify that for identified high risk

significant conditions, due to equipment availability and/or system configurations,

contingency measures were identified and incorporated into the overall outage and

contingency response plan. Furthermore, the inspectors frequently discussed risk

conditions and designated protected equipment with Operations and outage

management personnel to assess licensee awareness of actual risk conditions and

mitigation strategies.

Shutdown and Cooldown Process

The inspectors witnessed the shutdown and cooldown of Unit 3 in accordance with

licensee procedures OPDP-1, Conduct of Operations; 3-GOI-100-12A, Unit Shutdown

from Power Operations to Cold Shutdown and Reduction in Power During Power

Operations; and 3-SR-3.4.9.1(1), Reactor Heatup or Cooldown Rate Monitoring.

Decay Heat Removal

The inspectors reviewed licensee procedures 3-OI-74, Residual Heat Removal System

(RHR); 3-OI-78, Fuel Pool Cooling and Cleanup System; and Abnormal Operating

Instruction 0-AOI-72-1, Alternate Decay Heat Removal System Failures; and conducted

a main control room panel and in-plant walkdowns of system and components to verify

correct system alignment. During planned evolutions that resulted in an increased

outage risk condition of Yellow for shutdown cooling, inspectors verified that the plant

conditions and systems identified in the risk mitigation strategy were available. In

addition, the inspectors reviewed controls implemented to ensure that outage work was

18

RADIATION SAFETY

Cornerstone: Occupational Radiation Safety (OS)

2RS1 Radiological Hazard Assessment and Exposure Control

a.

Inspection Scope

Radiological Hazard Assessment: The inspectors reviewed a number of radiological

surveys, including those performed for airborne areas, of locations throughout the facility

including the Unit 3 (U3) drywell, Unit 1 (U1), Unit 2 (U2), and U3 reactor buildings, the

turbine building, and the independent spent fuel storage installation (ISFSI). The

inspectors also walked down many of the same areas and select radioactive material

storage locations with a survey instrument, evaluating material condition, postings, and

radiological controls. Of specific interest was the Condensate Storage Tank area which

due to a liquid radwaste processing problem created an actual radiation area outside the

building, near on-going work. The inspectors observed jobs in radiologically risk-

significant areas including high radiation areas and areas with, or with the potential for,

airborne activity. The inspectors evaluated the surveys in relation to the identified

hazards for sufficient detail and frequency.

Instructions to Workers: During plant walk downs, the inspectors observed labeling and

radiological controls on containers of radioactive material. The inspectors also reviewed

radiation work permits (RWP) used for accessing high radiation areas and airborne

areas, verifying that appropriate work control instructions and electronic dosimeter (ED)

setpoints had been provided and to assess the communication of radiological control

requirements to workers. The inspectors reviewed selected ED dose and dose rate

alarms, to verify workers properly responded to the alarms and that the licensees review

of the events was appropriate. The inspectors observed pre-job RWP briefings and

health physics technician coverage of workers. The inspectors reviewed the various

methods being used to notify workers of changing or changed radiological conditions.

Contamination and Radioactive Material Control: The inspectors observed the release

of potentially contaminated items from the radiologically controlled area (RCA) and from

contaminated areas such as the drywell. The inspectors also reviewed the procedural

requirements for, and equipment used to perform, the radiation surveys for release of

personnel and material. During plant walk downs, the inspectors evaluated radioactive

material storage areas and containers, including satellite RCAs and the low level

radwaste facility, assessing material condition, posting/labeling, and control of

materials/areas. In addition, the inspectors reviewed the sealed source inventory and

verified labeling, storage conditions, and leak testing of selected sources. The

inspectors verified if Category 1 and 2 sealed sources had been appropriately reported

to the National Source Tracking System and physically verified the presence and

controls of these sources. The sources were verified to be physically present and in

proper working order.

24

Enclosure

Radiological Hazards Control and Work Coverage: The inspectors evaluated licensee

performance in controlling worker access to radiologically significant areas and

monitoring jobs in-progress associated with the Unit 3 refueling outage. Established

radiological controls were evaluated for selected tasks including diver area setup for

torus underwater coatings inspection and desludging activities, equipment staging for

control rod drive work, reactor water cleanup sludge sampling, and work to support the

extended power uprate for Unit 3. The inspectors evaluated the effectiveness of

radiation exposure controls, including air sampling, barrier integrity, engineering controls,

and postings through a review of both internal and external exposure results. The

inspector followed up on two minor airborne radioactivity events.

During walk downs with a radiation survey meter, the inspectors independently verified if

ambient radiological conditions were consistent with licensee performed surveys, RWPs,

and pre-job briefings; observed the adequacy of radiological controls; and observed

controls for radioactive materials stored in the spent fuel pool. ED alarm set points and

worker stay times were evaluated against area radiation survey results for drywell and

refueling floor activities.

Risk-Significant High Radiation Area and Very High Radiation Area Controls: The

inspectors discussed the controls and procedures for locked-high radiation areas

Findings

.1

Failure to adequately secure radioactive shipping container contents for transport

Introduction: A self-revealing Green Non-Cited Violation (NCV) of 10 CFR 71.5,

Transportation of Licensed Material, was identified for the licensees failure to ensure

proper packaging of two DOT 7A Type A packages as required by 49 CFR 173.475(e),

Quality Control Requirements Prior To Each Shipment Of Class 7 (Radioactive)

Materials.

Description: On March 22, 2010, the licensee shipped control rod drive mechanisms

(CRDMs) to GE Hitachi Nuclear (GEH) for refurbishment in six Department of

Transportation (DOT) approved Type A boxes. Each box contained four CRDMs. In a

letter dated September 17, 2010, GEH informed the licensee that their receipt inspection

of containers 1343-S and 966-S on April 23, 2010, identified that pig shield containment

lid restraint bars designed to secure the CRDMs and pig shields in place were not

installed and were laying loose in the bottom of the container. The licensee documented

the issue in PER 236118. Licensee investigation determined that the radwaste

packaging inspector failed to follow procedural requirements and verify that the CRDMs

were properly secured within the container to prevent movement during shipping. The

inspectors reviewed the Container Certification, container closure procedure for the

CRDM boxes, licensee radioactive material shipment procedures, and engineering

documents concerning the container meeting DOT 7A requirements. The inspectors

noted that although the container closure procedure did not specifically address internal

packaging and the restraint bars, the container certification states that All contents must

be securely positioned to prevent shifting during normal conditions of transport., and

that site procedural guidance requires verification that the contents of the package have

been secured and satisfies the requirements of 10 CFR 71.87, prior to shipment.

Analysis: The failure to properly secure, or adequately block or brace the material within

a Class 7 (radioactive) materials package to prevent movement during transport prior to

shipment was determined to be a performance deficiency. Specifically, the licensee

failed to follow established site procedures and applicable documents provided by the

package vendor for package inspection and verification to ensure materials are secured

within containers. The finding was more than minor because it is associated with the

Public Radiation Safety Cornerstone, Plant Facilities/Equipment and Instrumentation

attribute, involving transportation packaging and adversely affected the cornerstone

objective to ensure adequate protection of public health and safety from exposure to

radioactive materials released into the public domain as a result of routine civilian

nuclear reactor operation. Specifically, the failure to correctly secure the package

contents to prevent movement could have resulted in damage or failure of the container

during transportation. The significance of the finding was evaluated using IMC 0612,

Appendix D, Public Radiation Safety Significance Determination Process. The issue

was evaluated using the Public Radiation Safety flowchart because it involved

radioactive material control, specifically, transportation. The finding was determined to

be of very low safety significance (Green) because it did not involve radiation limits being

30

Enclosure

exceeded, a package breach, a certificate of compliance issue, a low-level burial ground

non-conformance, or a failure to make emergency notifications.

The cause of this finding was directly related to the cross cutting aspect of Documents,

Procedures and Component Labeling in the Resources component of the Human

Performance area because the licensee did not effectively incorporate package design

specifications into their transportation program to ensure that all internal restraining

devices are correctly installed to secure the CRDM in place to prevent damage to the

transport package. H.2(c)

Enforcement: 10 CFR 71.5, Transportation of Licensed Material, required, in part, that

each licensee who transports licensed material outside the site of usage, as specified in

the NRC license, or where transport is on public highways, or who delivers licensed

material to a carrier for transport, shall comply with the applicable requirements of the

DOT regulations in 49 CFR Parts 107, 171 through 180, and 390 through 397,

appropriate to the mode of transport.

49 CFR 173.475(e), Quality Control Requirements Prior To Each Shipment Of Class 7

(Radioactive) Materials, required, in part, that before each shipment of any Class 7

(radioactive) materials package, the offeror must ensure, by examination or appropriate

tests, that each special instruction for filling, closing, and preparation of the packaging

for shipment has been followed. Licensee procedure RWTP-100, Radioactive

Material/Waste Shipments, contains package inspection and verification requirements

to ensure materials are secured within containers.

Contrary to the above, on March 22, 2010, the licensee failed to comply with the

applicable requirements of DOT regulation 49 CFR 173.475(e) for transport of licensed

material. Specifically, the licensee failed to follow Container Certification guidance, in

that the CRDMs were not properly packaged and secured inside two CRDM shipping

containers as required by licensee procedure RWTP-100. Because this violation was of

very low safety significance and it was entered into the licensees CAP (SR 570902), this

violation is being treated as an NCV, in accordance with Section 2.3.2 of the NRC

Enforcement Policy. (NCV 05000259, 260, 296/2012003-02; Failure to Properly Prepare

a DOT Type A Package for Transport)

.2

Failure to Implement DOT Type A Package Closure Requirements

Introduction: A self-revealing Green Non-Cited Violation (NCV) of 10 CFR 71.5,

Transportation of Licensed Material, was identified for the licensees failure to properly

close a DOT 7A Type A packages as required by DOT 49 CFR 173.475(f) Quality

Control Requirements Prior To Each Shipment Of Class 7 (Radioactive) Materials.

Description: On September 7, 2011, the licensee shipped a DOT approved Type A

shipping container, containing an ISP surveillance capsule, to MP Machinery and

Testing, LLC (MPM) for analysis of the contents. In a letter dated September 9, 2011,

MPM informed the licensee that upon arrival at the MPM facility the closure bolts on the

shipping container were found to be undertorqued at 30 ft-lbs torque, not 390 ft-lbs

torque as specified in the DOT Package Certification provided by MPM. The licensee

31

Enclosure

documented the issue in PER 431446. Licensee investigation determined that the ISP

surveillance capsule shipping container closure bolts did not have the correct torque

applied due to inadequate procedure guidance, unfamiliarity of the workers with the task,

and a lack of procedure use and adherence. Preparation of the surveillance capsule for

shipment occurred over several months, the Technical Instruction was revised during the

period, and the container instructions provided by the vendor were not used during

loading activities. The inspectors reviewed the DOT Package Certification, container

loading and shipping instructions, Technical Instruction for obtaining and packaging the

Reactor Vessel Test Specimens (both revisions), and the work order used to remove

and package the ISP surveillance capsule for shipment. The inspectors noted that

although detailed instructions for loading and closure of the container were provided by

the vendor, the instructions and required container closure torque values were not

included, or referenced, in the Technical Instruction or the work package.

Analysis: The failure to properly close a Class 7 (radioactive) materials package was

determined to be a performance deficiency. Specifically, the licensee failed to follow

established site procedures and applicable vendor documents for closing the package

resulting in inadequate torque of the shipping container closure bolts. The finding was

more than minor because it is associated with the Public Radiation Safety Cornerstone,

Plant Facilities/Equipment and Instrumentation attribute, involving transportation

packaging and adversely affected the cornerstone objective to ensure adequate

protection of public health and safety from exposure to radioactive materials released

into the public domain as a result of routine civilian nuclear reactor operation.

Specifically, the failure to apply the correct torque to the package closure bolts could

have resulted in incomplete sealing of the container or failure of the cover bolts during

transportation. The significance of the finding was evaluated using IMC 0612, Appendix

D, Public Radiation Safety Significance Determination Process. The issue was

evaluated using the Public Radiation Safety flowchart because it involved radioactive

material control, specifically, transportation. The finding was determined to be of very

low safety significance (Green) because it did not involve radiation limits being

exceeded, a package breach, a certificate of compliance issue, a low-level burial ground

non-conformance, or a failure to make emergency notifications

The cause of this finding was directly related to the cross cutting aspect of Documents,

Procedures and Component Labeling in the Resources component of the Human

Performance area because the licensee did not effectively incorporate the vendor

provided container loading and shipping instructions into their work package and

transportation program to ensure correct torque values were used to close the shipping

container. H.2(c)

Enforcement: 10 CFR 71.5, Transportation of Licensed Material, required, in part, that

each licensee who transports licensed material outside the site of usage, as specified in

the NRC license, or where transport is on public highways, or who delivers licensed

material to a carrier for transport, shall comply with the applicable requirements of the

DOT regulations in 49 CFR Parts 107, 171 through 180, and 390 through 397,

closed and sealed.

Contrary to the above, on September 7, 2011, the licensee failed to comply with the

applicable requirements of DOT regulation 49 CFR 173.475(f) for transport of licensed

material. Specifically, the licensee failed to properly close an opening in the containment

system of a Class 7 (radioactive) materials package. Because this violation was of very

these dates. Additionally, the inspectors review also included the Integrated Trend

Reports (ITR) from the first and second quarters of fiscal year 2012. The licensee

reports covered the period of October 1, 2011, to March 31, 2012. Furthermore, the

inspectors verified that adverse or negative trends identified in the licensees PERs,

periodic reports and trending efforts were entered into the CAP. Inspectors interviewed

the appropriate licensee staff and also reviewed procedures, NPG-SPP-02.8, Integrated

Trend Review and NPG-SPP-02.7, PER Trending.

The purpose of the licensees integrated trend reviews was to identify the top site and

departmental issues (gaps to excellence) requiring management attention. Other

objectives were to provide status of the top issues and their progress to resolution,

identify continuing issues, emerging trends and issues to be monitored, review progress

towards resolving past top issues, review issues identified by external organizations

such as the NRC, INPO, Nuclear Safety Review Board (NSRB), QA, etc., and determine

why they were not identified by line organizations. This activity constituted one

semiannual trend review inspection sample.

b.

Findings and Observations

No findings were identified, but the inspectors identified a number of observations as

discussed below.

Inspectors observed licensee-identified issues and trends in both the first and second

quarter ITRs that were identical or similar in nature. Inspectors reviewed the repeat

issues to assess the licensees progress of corrective actions associated with the issues

and trends identified. Some of the more notable site/departmental issues were as

follows:

Corrective Action Program (CAP): The CAP has not been considered as a core

business function by the station. Improvement is needed with problem identification,

cause evaluations and timely completion of corrective actions. This issue was

documented in PERs 346645 and 471366.

Human Performance/Standards: Human performance practices resulted in

consequential events, specifically: procedure use and adherence, procedure quality,

accountability, human performance fundamentals, and the observation program.

This issue was documented in PERs 410308 and 491985.

Procedure Use and Adherence: The first quarter 2012 ITR included this in the

Human Performance area (Issue #2) and developed actions to drive rigorous use of

procedures throughout all organization. The second quarter 2012 ITR included this

with the Procedure/Work Order Quality/Procedure Use and Adherence area (Issue

1. 2). This issue was documented in PERs 410308 and 491985.

The second quarter ITR contained fifteen fundamental problem statements that were

developed as a result of the 95003 supplemental inspection. The process is intended to

determine the root organizational and/or cultural causes of these issues. Corrective

actions were under development for these fifteen problem areas at the end of the

reporting period.

Enclosure

The inspectors conducted an independent review of the licensees CAP to identify

potential adverse trends. The inspectors identified a potential adverse trend with the

licensees control of transient combustible materials in plant areas. A review of PERs

from January 2012 to June 2012 revealed twelve PERs associated with transient and

excessive combustible materials in plant areas however, a PER that identified this as a

trend was not identified by the licensee staff. The inspectors discussed this issue with

the appropriate licensee staff and PER 577382 was initiated to document this as an

adverse trend.

4OA3 Event Follow-up

.1

Unit 3 Automatic Reactor Scram Following Refueling Outage

a.

Inspection Scope

On May 22, 2012, while recovering from a refueling outage with control rod and main

turbine generator off-line testing in progress, Unit 3 automatically scrammed from 19.5

percent power. Unit 3 scrammed due to a loss of offsite power when an inadvertent

actuation of 3A Unit Station Service Transformer (USST) differential relay 387SA

resulted from an incorrect relay setting. Inspectors promptly responded to the control

room and verified that the unit was stable in Mode 3 (Hot Shutdown), and confirmed that

all safety-related mitigating systems had operated properly. Inspectors evaluated safety

equipment and operator performance before and after the event by examining existing

plant parameters, strip charts, plant computer historical data displays, operator logs, and

the critical parameter trend charts used for the post-trip report. Inspectors also

interviewed responsible on-shift operations personnel, examined the implementation of

the applicable annunciator response procedures and abnormal operating instructions,

including 3-AOI-100-1, Reactor Scram, and reviewed the written notification made in

accordance with 10 CFR 50.72. Inspectors discussed the preliminary cause of the

incorrect relay setting with responsible Operations and Engineering personnel and

monitored Plant Oversight Review Committee (PORC) event review and restart

meetings. This review included only initial event follow-up.

b.

Findings

No findings were identified.

.2

Unit 3 Manual Reactor Scram Following Refueling Outage

a.

Inspection Scope

On May 24, 2012, Unit 3 was manually scrammed from Mode 2 (less than 1% rated

power) when operators ranged down the Intermediate Range Monitor (IRM) 'H'

instrument, instead of up, resulting in half scram on Reactor Protection System (RPS) 'B'

trip system. The half scram was being reset after IRM 'H' was properly ranged. As the

operator adjusted the reset scram switch, a spike on IRM 'A' was received on the RPS

'A' trip system, resulting in a partial rod insertion. When the operator identified multiple

38

Enclosure

rods inserting, the actions of the Reactor Scram Procedure, 3-AOI-l00-1, were followed

and a manual scram was inserted. The inspectors evaluated safety equipment and

operator performance before and after the event by examining existing plant parameters,

strip charts, plant computer historical data displays, operator logs, the alarm typewriter

Sequence of Events printout, and the critical parameter trend charts in the post-trip

report. The inspectors interviewed responsible on-shift Operations personnel, examined

the implementation of annunciator response and abnormal operating procedures,

(including 3-AOI-100-1, Reactor Scram) and reviewed the written notification made in

accordance with 10 CFR 50.72. This review included only initial event follow up.

b.

Findings

No findings were identified

.3

Unit 3 Automatic Reactor Scram and Forced Outage

a.

Inspection Scope

On May 29, 2012, Unit 3 automatically scrammed from 78 percent power due to a power

to load unbalance (i.e., main generator load reject) automatic trip of the main turbine

generator from an A-B phase trip of the main transformer differential relay 387T. The

licensee identified the cause of the differential relay trip to be a B phase current

transformer manufactured and installed with opposite polarity. Preliminarily, the licensee

revealed that factory acceptance and field testing failed to detect the manufacturing

defect of reverse polarity. Inspectors promptly responded to the control room and

verified that the unit was stable in Mode 3 (Hot Shutdown), and confirmed that all safety-

related mitigating systems had operated properly. Inspectors evaluated safety

equipment and operator performance before and after the event by examining existing

plant parameters, strip charts, plant computer historical data displays, operator logs, and

the critical parameter trend charts used for the post-trip report. Inspectors also

interviewed responsible on-shift operations personnel, examined the implementation of

the applicable annunciator response procedures and abnormal operating instructions,

including 3-AOI-100-1, Reactor Scram, and reviewed the written notification made in

accordance with 10 CFR 50.72. Inspectors discussed the preliminary cause of the failed

acceptance and installation testing with responsible Operations and Engineering

personnel. This review included only initial event follow-up.

Operators commenced restart of Unit 3 (i.e., entered Mode 2) on June 2 and achieved

full power on June 6, 2011. During this short forced outage the inspectors examined the

conduct of critical outage activities pursuant to technical specifications, applicable

procedures, and the licensees risk assessment and maintenance plans. Some of the

more significant outage activities monitored, examined and/or reviewed by the

inspectors were as follows:

Plant Oversight Review Committee (PORC) event review and restart meetings.

Reactor startup and power ascension activities per 3-GOI-100-1A, Unit Startup

Reactor vessel and coolant heatup per 3-SR-3.4.9.1(1), Reactor Heatup and

Cooldown Rate Monitoring

39

Enclosure

Outage risk assessment and management

Control and management of forced outage and emergent work activities

Corrective Action Program

The inspectors reviewed PERs generated during the Unit 3 forced outage and attended

management review committee meetings to verify that initiation thresholds, priorities,

mode holds, and significance levels were assigned as required.

(Closed) Licensee Event Report (LER) 05000296/2011-003-00, Automatic Reactor

Scram Due to a Main Turbine Generator Load Reject.

a.

Inspection Scope

On September 28, 2011, Unit 3 automatically scrammed from 100 percent power due to

a power to load unbalance (i.e., main generator load reject) automatic trip of the main

turbine generator (MTG) caused by a broken debris screen. The initial follow-up of this

event by the inspectors was documented in Section 4OA3.10 of IR 05000296/2011004.

The inspectors reviewed the applicable LER that was issued on November 28, 2011,

and its associated PER 440539, which included the root cause analysis (RCA) and

corrective actions. The licensee concluded that the direct cause of the Unit 3 turbine trip

and scram was the isolated-phase bus C debris screen failure.

Undervoltage Trip for the Reactor Protection System 1A1 Relay that Did Not Meet

Acceptance Criteria During Several Surveillances

a.

Inspection Scope

The inspectors reviewed Revision 2 of LER 05000259/2011-009 dated April 25, 2012,

PER 486780, and the associated operability determination, and corrective action plans.

This revised LER was submitted to provide the results of the licensees completed

investigation and evaluation of a second Reactor Protection System (RPS) relay that did

not meet its acceptance criteria during previous surveillance testing for the same reason.

The original LER 05000259/2011-009-00 dated December 5, 2011, the revised LER

05000259/2011-009-01 dated January 31, 2012, applicable PERs 413140 and 442914,

including root cause analysis, operability determination and corrective action plans, were

reviewed by the inspectors and documented in Sections 4OA3.1 and 4OA7 of NRC IR

40

Enclosure

05000259/2012002. As a result of this prior review, the licensee had identified one

violation of NRC requirements associated with Unit 1 RPS 1A1 relay.

On January 6, 2012, while performing an operability determination for the Unit 3 reactor

protection system (RPS) 3C1 relay undervoltage trips, the licensee determined that the

as-found undervoltage trip setpoint for the Unit 3 relay was less than the required

acceptance criteria during several technical specification surveillances. Seven of the

last thirteen surveillance test results were below the technical specification acceptance

criteria. Therefore, based on performance history, the RPS 3C1 relay was determined to

be inoperable from June 9, 2006, to February 2, 2012, when the relay was replaced.

The licensee determined the previous root cause and corrective actions were applicable

in that the surveillance test program did not require past operability reviews when out of

calibration technical specification conditions were corrected during surveillances.

The inspectors reviewed the second LER revision and verified that the supplemental

information provided in the LER was complete and accurate and that the information

was not of a significant nature to warrant any change to the original LER finding.

This licensee identified violation constitutes an additional example as documented in

NRC IR 05000259/2012002 and is not an individual non-cited violation. Further

corrective actions for this additional example are expected to be taken in conjunction

with corrective actions for the previous violation.

b.

Findings

One finding for the original and Revision 1 of the LER was previously identified in

Section 4OA7 of NRC IR 05000259/2012002. No additional findings were identified.

The revised LER is considered closed.

(Closed) Licensee Event Report (LER) 05000296/2012-001-00, Annunciator Panel

Power Supply Fire in Unit 3 Control Room

a.

Inspection Scope

On January 26, 2012, Unit 3 main control room operators smelled smoke and observed

a flame coming from the bottom of an annunciator panel 3-XA-55-5A power supply. Fire

Operations personnel arrived on the scene within five minutes. The affected circuit

breaker was opened and fire extinguished within ten minutes. Operations personnel

increased plant monitoring to compensate for indications that lost their alarming

functions when the circuit breaker was opened. The fire damage was limited to the

failed annunciator power supply and the power supply directly above it. The inspectors

reviewed the details surrounding this event, interviewed operations and engineering

personnel involved with this issue and reviewed the licensees apparent cause

determination report. This was captured in the licensees corrective action program as

problem event report (PER) 496592. This LER is closed.

41

Enclosure

b.

Findings

Introduction: A self-revealing Green finding (FIN) was identified for the licensees failure

to perform preventive maintenance on the Unit 3 Main Control Room (MCR) annunciator

power supplies. As a result, a power supply failed which led to a fire in annunciator

panel 3-XA-55-5A in the Unit 3 MCR.

Description: On January 26, 2012, Unit 3 main control room operators smelled smoke

and observed a flame coming from the bottom of an annunciator panel power supply.

Within ten minutes, the Fire Brigade responded to the MCR and the circuit breaker was

opened for the affected power supply which extinguished the fire. Damage was confined

to two power supplies in annunciator panel 3-XA-55-5A. The damaged power supplies

were replaced on January 27, 2012 in accordance with Work Order (WO) 113155456.

Corrective action document PER 496592 identified the direct cause of the annunciator

power supply failure as an overcurrent condition caused by a failed electrolytic capacitor.

This PER referenced EPRI recommendations to change out components with electrolytic

capacitors on a time based frequency. TVAs apparent cause concluded the power

supply (capacitor), installed for thirty four (34) years, experienced an age related failure

due to a lack of preventive maintenance.

Age-related failures of electrolytic capacitors have been documented in the industry.

Electric Power Research Institute (EPRI) document, TR-112175, Capacitor Application

and Maintenance Guide, dated August 1999, stated that capacitor change outs are

performed between 7 and 15 years depending on vendor recommendations and plant

operating experience. Another EPRI document, Power Supply Maintenance and

Application Guide (1003096), dated December 2001, stated that many of the power

supplies that failed had been in service greater than 15 years on average. Since 2008

three PERs have been entered in TVAs CAP that document similar failures of these

annunciator power supplies on both Unit 2 and 3 main control room panels. PER

391479 was initiated in June 2011 to evaluate the equipment reliability classification of

these power supplies. Corrective actions to evaluate the annunciator power supply

preventive maintenance strategy were in progress when the fire occurred.

These power supplies were classified as Quality-Related, Non-Critical, Low Duty-Cycle,

Mild Service Condition in accordance with licensee procedure NPG-SPP-09.18.2,

Equipment Reliability Classification. Licensee procedure TVA-NQA-PLN89-A, Nuclear

Quality Assurance Plan stated that the nuclear maintenance program including

corrective and preventive maintenance shall ensure that quality-related structures,

systems and components are maintained at a level sufficient to perform their intended

functions.

Analysis: The failure to perform preventive maintenance on the Unit 3 annunciator

power supplies prior to their age related failure was a performance deficiency.

Specifically, TVA procedure TVA-NQA-PLN89-A, Nuclear Quality Assurance Plan stated

that the nuclear maintenance program including corrective and preventive maintenance

shall ensure that quality-related structures, systems and components are maintained at

a level sufficient to perform their intended functions. These power supplies were

classified as Quality-Related according to TVA procedure NPG-SPP-09.18.2, Equipment

42

Enclosure

Reliability Classification. As a result of the performance deficiency, a Unit 3 MCR

annunciator power supply was left in service for 34 years, failed due to an aged

electrolytic capacitor and resulted in an over-current related fire. The performance

deficiency was determined to be more than minor because it was considered sufficiently

similar to example 4.f of Inspection Manual Chapter (IMC) 0612, Appendix E, for an

issue that resulted in a fire hazard in a safety-related area of the plant. The finding was

associated with the Initiating Events Cornerstone and initially characterized according to

IMC 0609, Significance Determination Process (SDP), Attachment 4, Phase 1 - Initial

Screening and Characterization of Findings. The results of this analysis required a

phase 3 evaluation in accordance with IMC 0609 because the finding increased the

likelihood of and actually caused a fire in the Unit 3 MCR. The regional Senior Reactor

Analyst performed a Phase 3 analysis for the issue. Pictures were provided to an NRC

contractor who provides expertise in fire damage for the agency. It was determined that

the configuration of the fire would not likely result in damage to anything of significance

because the metal box that the annunciators power supplies are located in, would

prevent propagation of the fire beyond the box. It is also unlikely that enough heat or

smoke could be created to require control room evacuation, which would impact the

human actions that would be performed to shut down the plant. Without an impact to

additional plant equipment, or a major impact on human action failure rates, the finding

was determined to be Green. The cause of this finding was related to the cross cutting

aspect of Problem Identification in the Corrective Action Program component of the

Problem Identification and Resolution area, because the licensee was aware of three

previous failures of these power supplies in July 2009 and should have recognized that

the electrolytic capacitors, installed beyond their recommended service life, required

replacement prior to failure P.1(a).

Enforcement: Enforcement action does not apply because the performance deficiency

did not involve a violation of regulatory requirements since the main control room

annunciator power supplies were not safety-related. Because the finding does not

involve a violation, was entered into the licensees corrective action program as PER

496592, and has very low safety significance, it is identified as FIN 05000296/2012003-

04, Failure to Perform Preventive Maintenance on the Unit 3 Main Control Room

Annunciator Power Supplies.

All proprietary information reviewed by the inspectors as part of routine inspection

activities were properly controlled, and subsequently returned to the licensee or

disposed of appropriately.

4OA7 Licensee-Identified Violations

The following violation of very low safety significance (Green) was identified by the

licensee and is a violation of NRC requirements which met the criteria of the NRC

Enforcement Policy, for being dispositioned as a Non-Cited Violation:

A violation of Technical Specification 5.4.1.a was identified by the licensee for the

failure to establish adequate work instructions to ensure proper installation of the gap

setting between the actuator stem and valve stem of Unit 1 HPCI, (High Pressure

Coolant Injection), turbine stop valve, 1-FCV-073-0018. On April 19, 2012, during

the performance of a quarterly surveillance test the turbine stop valve, 1-FCV-073-

0018, failed to close upon repeated demands. A Phase 3 analysis determined the

significance of the finding was very low safety significance (Green) The regional

Senior Reactor Analyst performed a Phase 3 SDP analysis on the finding. The risk

was dominated by the unavailability of the HPCI during the repair time after

discovery of the Stop Valve issue. The finding was determined to be GREEN in the

SDP, primarily due to the short period of time it was fully non-functional. The

licensee initiated PER 539040 to enter the issue into their corrective action program.
