SUBJECT: JOSEPH M. FARLEY NUCLEAR PLANT - NRC PROBLEM IDENTIFICATION

AND RESOLUTION INSPECTION REPORT 05000348/2005008 AND

05000364/2005008

Dear Mr. Stinson:

On August 26, 2005, the U. S. Nuclear Regulatory Commission (NRC) completed a team

inspection at the Joseph M. Farley Nuclear Plant. The enclosed report documents the

inspection results which were discussed on August 25, 2005, with Mr. Todd Youngblood and

other members of your staff.

This inspection was an examination of activities conducted under your licenses as they relate to

the identification and resolution of problems, and compliance with the Commissions rules and

regulations, and the conditions of your operating licenses. Within these areas, the inspection

involved selected examination of procedures and representative records, observations of

activities, and interviews with personnel.

Based on the sample selected for review, the team concluded that, in general, problems were

properly identified, evaluated, and corrected. There were two NRC-identified findings and one

self-revealing finding of very low safety significance (Green) identified during this inspection.

One NRC-identified finding and the self-revealing finding were determined to be violations of

NRC requirements. The remaining finding is associated with a failure to correct a long-standing

condition adverse to quality. The first violation is associated with a failure to promptly identify a

condition adverse to quality and the second violation is associated with inadequate corrective

actions to preclude recurrence. However, because of their very low safety significance and

because they have been entered into your corrective action program, the NRC is treating these

violations as non-cited violations in accordance with Section VI.A of the NRCs Enforcement

Policy. If you deny any of these findings, you should provide a response within 30 days of the

date of this inspection report, with the basis for your denial, to the Nuclear Regulatory

Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the

Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear

Regulatory Commission, Washington DC 20555-0001; and the NRC Resident Inspector at the

Farley Nuclear Plant.

In addition, several examples of minor problems were identified including equipment failures

that were inappropriately classified as not being functional failures, industry operating

SNC 2

experience that was ineffectively evaluated, and past operability determinations that lacked

proper documentation.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its

enclosure will be available electronically for public inspection in the NRC Public Document Room

or from the Publicly Available Records (PARS) components of NRCs document system (ADAMS).

SUMMARY OF ISSUES

IR 05000348/2005-008 and 05000364/2005-008; 08/08/2005 - 08/12/2005 and 08/22/2005 -

08/26/2005; Joseph M. Farley Nuclear Plant, Units 1 and 2; Identification and Resolution of

Problems.

The inspection was conducted by a senior project engineer, two resident inspectors, and a

health physics inspector. Three Green findings were identified of which two were non-cited

violations (NCVs). The significance of most findings is indicated by their color (Green, White,

Yellow, Red) using IMC 0609,Significance Determination Process (SDP). Findings for which

the SDP does not apply may be Green or be assigned a severity level after NRC management

review. The NRC's program for overseeing the safe operation of commercial nuclear power

reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.

Problem Identification and Resolution (PI&R)

The team determined that the licensee was generally effective in identifying problems and

entering them into the corrective action program (CAP). The threshold for problem

identification was determined to be low. CAP-related audits were effective in identifying

deficiencies for resolution. Condition Report trending under the CAP has had success in

bringing about corrective actions for identified adverse trends. The team determined that the

licensee properly prioritized issues entered into the CAP. Generally, the licensee performed

adequate evaluations that were technically accurate and sufficiently detailed. Corrective

actions developed and implemented for problems were generally timely, effective, and

appropriate to the problem. One Green finding for failure to correct a long-standing condition

adverse to quality and two Green non-cited violations for a failure to promptly identify a

condition adverse to quality and inadequate corrective actions to preclude recurrence were

identified. In addition, several examples of minor problems were identified including equipment

failures that were inappropriately classified as not being functional failures, industry operating

experience that was ineffectively evaluated, and past operability determinations that lacked

proper documentation. Management emphasized the need for staff to identify and resolve

issues using the CAP. A safety conscious work environment was evident.

A. NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

• Green. An NRC-identified non-cited violation of 10 CFR Part 50, Appendix B, Criterion

XVI, was identified for failure to take corrective actions to preclude repetition of a

significant condition adverse to quality. Specifically, corrective actions taken to develop

a solid state protection system (SSPS)/7300 troubleshooting guideline following a Unit 2

SSPS/7300 troubleshooting-related reactor trip on April 12, 2004, was inadequate to

preclude the recurrence of another SSPS/7300 troubleshooting-related event on April

28, 2005.

This finding is more than minor because it affects the Mitigating Systems Cornerstone

attribute of equipment performance and adversely impacted the cornerstone objective in

that the SSPS/7300 troubleshooting guidance did not provide the necessary steps to

facilitate timely (i.e., within the TS LCO) determination of a SSPS/7300 process channel

Enclosure

failure. This finding is of very low safety significance because the B train of SSPS was

maintained operable at all times. (Section 4OA2c.(2)(b))

Cornerstone: Barrier Integrity

• Green. A self-revealing non-cited violation of 10 CFR 50, Appendix B, Criterion XVI,

Corrective Action, was identified for failure to identify a significant condition adverse to

quality. Specifically, following the July 15, 2003, trip of the 1A containment spray pump

room cooler, the licensee failed to identify an existing degraded time delay relay.

Consequently, for the period between July 15, 2003, until corrected on May 1, 2004, the

degraded condition of the 1A containment spray pump room cooler rendered it

vulnerable to run/stop/hot restart scenarios that could be encountered during the

response to a large break loss of coolant accident (LOCA).

This finding is more than minor because it affects the Barrier Integrity Cornerstone

attribute of Barrier Performance and impacted the cornerstone objective in that tripping

of the room cooler could result in loss of the 1A containment spray pump safety function

due to overheating. This finding is of very low safety significance (Green) because the

1B containment spray pump and room cooler and all containment coolers were available

to ensure containment barrier integrity would be maintained in the event of a large break

LOCA or containment over pressure challenge. (Section 4OA2c.(2)(a))

• Green. An NRC-identified finding was identified for untimely resolution of excessive air

flow problems on the Unit 1 and Unit 2 Containment Air Particulate Radiation Monitors

(R-11). Excessive air flow through the moving filter paper caused the monitor to

become inoperable on numerous occasions since 1990. When R-11 was out of service,

the ability to detect low-level reactor coolant system (RCS) leakage was degraded.

This finding is more than minor because it is associated with the RCS Equipment and

Barrier Performance Attribute of the Barrier Integrity Cornerstone and adversely affects

the cornerstone objective in that the ability to detect low-level RCS leakage that may

indicate pressure boundary degradation was reduced. This finding could not be

evaluated using the Significance Determination Process (SDP) in accordance with IMC 0609 because the SDP for the RCS barrier only applied to a degraded barrier; not the

ability to detect a degraded barrier. Therefore, this finding was reviewed by regional

management and determined to be of very low safety significance (Green) because

alternate methods of detecting low-level RCS leakage were available whenever R-11

was out of service. (Section 4OA2c.(2)(c))

REPORT DETAILS

4. OTHER ACTIVITIES (OA)

4OA2 Problem Identification and Resolution (PI&R)

a. Effectiveness of Problem Identification

(1) Inspection Scope

The team reviewed selected condition reports (CRs) initiated since the previous NRC

PI&R inspection, conducted September 2003, to verify that problems were being

properly identified, appropriately characterized, and entered into the corrective action

program (CAP). The reviews primarily focused on issues associated with five risk

significant plant safety system areas: nuclear service water (SW); auxiliary feedwater;

component cooling water; emergency core cooling systems (ECCS); and vital electrical

systems. In addition to the system reviews, the team selected a sample of CRs that

were related to radiation protection and emergency preparedness to ensure coverage of

those cornerstones. The team also reviewed those CRs associated with licensee event

reports and findings identified in NRC inspection reports (IRs) issued since the last PI&R

inspection.

The team reviewed completed maintenance work orders (WOs), system health reports,

and the Maintenance Rule (MR) database for the five selected system areas to verify

that equipment deficiencies were being appropriately entered into the CAP and the MR

program. The team conducted walkdowns of equipment associated with the selected

systems to assess the material condition and to look for any deficiencies that had not

been entered into the CAP. The team reviewed temporary modifications, the main

control room deficiency list, operator workaround list, failed surveillances and any

acceptance criteria changes, control room operator logs, and the employee concerns

program to verify that equipment deficiencies (especially those involving the selected

systems) were entered into the CAP.

The team reviewed selected industry operating experience (OE) items, including NRC

generic communications, to verify that both types were appropriately evaluated for

applicability and whether issues identified through these reviews were entered into the

CAP. The team reviewed several licensee audits (focusing primarily on problem

identification and resolution) to verify that findings were entered into the CAP and to

verify that these findings were consistent with the NRCs assessment of the licensees

CAP. Trending of CRs under the CAP was also reviewed to determine if licensee-

identified trends were captured for resolution and if CAP statistics indicated any trends

that were not identified by the licensee.

The team attended several daily management update and site corrective action program

coordinator (CAPCO) meetings, as well as a corrective action review board meeting to

observe management and department CAPCO oversight functions in the corrective

action process. The team also interviewed personnel from operations, maintenance,

engineering, health physics, and emergency preparedness to evaluate their threshold

for identifying issues and entering them into the CAP.

Enclosure

2

Documents reviewed are listed in the Attachment.

(2) Assessment

The team determined that the licensee was effective in identifying problems and

entering them into the CAP. There was, however, one issue identified involving the

July 16, 2004, remote shutdown capability test of the 1C SW pump, in which the

necessity to cycle its associated switch twice before starting was recorded on the

surveillance test result sheet (STRS) of FNP-1-24.20; but, not in a CR where it could be

evaluated and trended under the CAP. Performance/documentation of such switch

cycling/cleaning on the STRS was also found to be permitted in precaution/limitation

4.4 of FNP-1-STP-73.1, Hot Shutdown Operability Verification; thereby, making it

potentially vulnerable to bypassing the CAP as well. To address this and related switch

cycling/cleaning potential vulnerabilities, the licensee generated CRs 20055108397 and

2005203550.

Based on observed samples, independent walkdowns, and staff interviews, the

threshold for problem identification was low. CRs provided complete and accurate

characterization of the subject issues. Equipment performance issues involving

maintenance effectiveness were for the most part being appropriately identified and

entered into the CAP. However, the team identified two CRs (i.e., CR 2003003388,

Degraded 1C Diesel Generator Speed Signal Generator, and CR 2005104677, Failure

of Service Water Battery Charger #3 to Load) where the associated equipment failure

was inappropriately categorized as not being a functional failure. The licensee

generated CRs 2005108425 and 2005108446, which acknowledged the

mis-classifications and confirmed that the respective functional failures would not have

caused (past or present) the MR performance criteria for the affected functions to be

exceeded.

With the exception of the two examples discussed below, the licensee was effective in

evaluating internal and external industry operating experience items for applicability and

entering issues into the CAP:

• NRC IR 05000348,364/2004004 identified that the licensees response to Information

Notice (IN) 94-68, Safety-Related Equipment Failures Caused By Faulted Indicating

Lamps, was narrow in scope and specifically did not address the diesel generators

(DGs). Although there had been a number of occurrences recorded in CRs involving

the DGs since 2000, actions taken had focused on restoring diesel operability and

more careful bulb replacement rather than eliminating the problem. The team verified

that the licensee had recently completed modifications to eliminate this problem on

both the diesels and the main steam atmospheric reliefs, as well as began an in-depth

review of the IN to determine if similar vulnerabilities exist.

• As documented in NRC Triennial Fire Protection (TFP) IR 05000348,364/2005006, the

licensee inappropriately made the assumption that a fire could not cause the spurious

opening of both the inboard and outboard reactor coolant system (RCS)-to-residual

Enclosure

heat removal (RHR) system supply isolation valves. The effects of fire on these

valves was discussed in INs 87-50, Potential Loss of Coolant Accident (LOCA) at High

and Low Pressure Interfaces From Fire Damage, 92-18 Potential For Loss of Remote

Shutdown Capability During a Control Room Fire, and 99-17, Problems Associated

With Post Fire Safe Shutdown Circuit Analysis. The licensee did not properly evaluate

these INs and inappropriately concluded they were not vulnerable to this failure.

Consequently, Units 1 and 2 had maintained both valves in the two RCS-to-RHR

supply lines energized making them susceptible to a breach in the high pressure - low

pressure interface boundary between the RCS and RHR systems. When the

condition was identified during the April 2005 TFP inspection, the licensee was in the

process of reviewing the issue again under RIS 2004-03, Risk Informed Approach for

Post Fire Safe Shutdown Associated Circuit Inspections. Subsequently, on April 29,

2005, the licensee de-energized one train of valves on both units to prevent

inadvertent actuation due to a fire.

CAP-related audits performed by Performance Evaluation, Quality Assurance (QA), and

department CAPCOs were effective in identifying issues and entering these deficiencies

into the CAP for resolution. Site management was involved in the CAP and focused

attention on significant plant issues.

CR trending under the CAP has had success in bringing about corrective actions for

identified adverse trends; however, trend identification was primarily keyed on tripping

established thresholds based on increases in CR populations for a given area.

Consequently, issues common to smaller CR populations, such as the heat exchanger

problems noted in NRC IR 05000348,364/2005003 or missed procedural

interdependencies and out-of-specification Agastat testing results noted during the

teams CR reviews, may go undetected without rigorous reviews at either end of the CR

process. For the examples noted, all were confirmed by the team to have been

captured for resolution by means other then the formal trending process (e.g., system

engineer, CR evaluation, etc.). It was noticed that the site CAPCO recently began

identifying repeat issues for possible adverse trends; but, as of the time of this

inspection, the need to perform the intended trend assessments had not been captured

in a CR. NRC IR 05000348,364/2005003 also documented the resident inspectors

questioning the validity of the justifications used in dispositioning 14 potential adverse

trends identified in the November 2004 - January 2005 CAP trend report as no adverse

trend. The teams review of the February - April 2005 CAP trend report revealed that

during the managers trend report review two of the subject areas (i.e., fire equipment

and performance monitoring) were appropriately reclassified as actual adverse trends.

In addition, CR 2005106889 identified areas for improvement related to data trending

and more timely/in-depth management review (i.e., addition of tertiary event codes and

review of the trend report outside the weekly managers meeting within 45 days). The

potential adverse trends for the period of May - July 2005, including the need for

assessment before capturing them in the associated CAP trend report, had not been

identified in CRs as of the end of this inspection; therefore, corrective action

effectiveness could not be assessed.

b. Prioritization and Evaluation of Issues

(1) Inspection Scope

The team reviewed selected CRs in order to verify that the licensee properly classified

and evaluated the problems in accordance with procedure NMP-GM-002, Corrective

Action Program. Accordingly, the teams review also assessed if the licensee

determined the apparent cause (root and contributing causes for significant conditions

adverse to quality) of problems and adequately addressed operability, reportability,

common cause, generic concerns, and extent of condition. More than a third of the CRs

reviewed were classified as either Severity Level (SL) 2 (requiring a root cause and

corrective actions to prevent recurrence) or SL 3 (requiring an apparent cause and

corrective actions to reduce the likelihood of recurrence). There were no SL1 CRs in

the overall population from which the CRs were selected.

(2) Assessment

With the exception of CRs 200400795 and 2003000917, the team determined that the

licensee properly prioritized issues entered into the CAP. The CRs in question were

associated with non-cited violations and should have been prioritized as SL 3 (versus SL

5 and SL 4, respectively) in accordance with NMP-GM-002. This was considered

administrative in nature since the required apparent cause was performed for each one.

Overall, the licensee performed adequate evaluations that were technically accurate and

sufficiently detailed. Consistent with QA audit findings, the team noted the following

exceptions:

• CR 2003000172, Unit 2 Solid State Protection System (SSPS) B Train Failure: During

surveillance testing of the Unit 2 SSPS B Train on January 29, 2003, and on March

21, 2003, the Logic C test failed at position 14 (Lo-Lo level start of the turbine driven

auxiliary feedwater pump (TDAFWP)). The licensee performed a root cause analysis,

but found there was not enough information available to make a root cause

determination. Therefore, various corrective actions were identified in the CR to be

performed so that data could be gathered in order to determine a root cause.

However, the team found that some of these corrective actions (i.e., resistance check

of logic switches to verify proper operation, failure analysis of the SSPS card, visual

inspections of card edge connections, and investigation into the cause of a bad card

selected from the warehouse) had not been completed. As a result, the root cause

was never determined; therefore, no past operability determination of the TDAFW

pump could be made. The CR described reasons why some of the actions were not

completed (e.g., too man power intensive, too costly, etc.). However, the decision not

to perform these corrective actions was not communicated to the root cause group as

required by NMP-GM-002. Furthermore, the licensees root cause effectiveness

review had determined that the corrective actions were effective when some of them

had never been completed and a root cause had never been determined. When

questioned about these discrepancies, the licensee initiated CR 2005108442.

Enclosure

5

• CR 2004002293, Gas Accumulation in Suction of the 2B Coolant Charging/High Head

Safety Injection (HHSI) Pump: The licensee had identified that the 2B HHSI pump

discharge check valve had a flaw which allowed approximately 40 gallons per minute

(GPM) of reverse flow through the pump when idle. A formal operability determination

had been performed which determined that HHSI pump discharge flows had been

balanced within established limits. However, documentation was not readily available

to demonstrate that the effects of the idle pump (i.e., the reverse flow) had been

considered with respect to post-accident operation of HHSI pump 2A and/or 2C.

Informal/uncontrolled information was eventually provided to the team that

substantiated proper post-accident operation of the 2A and 2C HHSI pumps, but this

information was not inherent to the resolution of CR 2004002293 or any of its

supporting justifications.

• CR 2004001281, 1A Containment Spray Pump Room Cooler Failure: The licensee

determined that a degraded time delay relay was the cause of the July 15, 2003, and

March 23, 2004, run/stop/hot restart trips experienced on the 1A containment spray

pump room cooler. Accordingly, the March 23, 2004, event was appropriately

identified by the licensee as a maintenance preventable failure. However, it was

apparent that the licensee had not considered past operability of the room cooler with

respect to its vulnerability to run/stop/hot restart scenarios that could be encountered

during the response to a large break loss of coolant accident (LOCA). (This condition

is further discussed in Section 4OA2c.(2)(a).)

Troubleshooting was considered an essential tool in problem evaluation. NRC IR

05000348,364/2004005 documented an observation of inconsistent troubleshooting

activities for 4160 volt breakers. The team also identified other troubleshooting-related

issues involving the evaluation/cause determination of failures in the SSPS/7300

process channels in Unit 2 and the failures of non-vital inverter 2F. SSPS/7300

troubleshooting is discussed further in Section 4OA2c.(2)(b) of this report. With respect

to the 2F inverter, troubleshooting efforts were unable to preclude two additional failures

(i.e., transfers to bypass on July 17 and 27, 2005) since its failure on July 1, 2005, which

resulted in returning to a MR (a)(1) status for the second time in two years. Suspecting

all three failures were the result of an intermittent transistor failure, the affected static

switch card was replaced after the third failure before returning the inverter to service in

August 2005. At that time, a more methodical approach to troubleshooting the 2F

inverter was implemented that included monitoring via an attached recorder. No further

failures of the 2F inverter had occurred by the conclusion of the inspection.

c. Effectiveness of Corrective Actions

(1) Inspection Scope

The team evaluated selected CRs to verify that the licensee had identified and

implemented timely and appropriate corrective actions to address problems. The team

determined whether the corrective actions were appropriate for the described problem,

as well as properly documented, assigned, and tracked to ensure completion. Selected

corrective actions were sampled for detailed review to independently verify that

Enclosure

6

corrective actions were implemented as intended. The sample selected for verification

included corrective actions associated with NRC findings and others from CRs

associated with the focus systems. Additionally, the team reviewed a sampling of the

oldest CRs to determine if implementation delays were appropriately justified.

(2) Assessment

Corrective actions developed and implemented for problems were generally timely,

effective, and appropriate to the problem. NRC IR 05000348,364/ 2004003 reflected

both the residents and licensees findings that corrective actions for several Severity

Level 2 (and 3) CRs had not always been sufficiently comprehensive to prevent (or

reduce the likelihood of) recurrence. As discussed below, the team identified similar

findings of missed opportunities for the CAP to promptly resolve problems.

(a) 1A Containment Spray Pump Room Cooler Failures

Introduction: A Green, self-revealing non-cited violation (NCV) of 10 CFR 50, Appendix

B, Criterion XVI, Corrective Action, was identified for failure to identify a significant

condition adverse to quality. Specifically, following the July 15, 2003 trip of the 1A

containment spray pump room cooler, the licensee failed to identify an existing

degraded time delay relay. Consequently, for the period between July 15, 2003, until

corrected on May 1, 2004, the degraded condition of the 1A containment spray pump

room cooler rendered it vulnerable to run/stop/hot restart scenarios that could be

encountered during the response to a large break LOCA.

Description: On March 23, 2004, during the performance of surveillance test procedure

FNP-1-STP-16.1, 1A Containment Spray Pump Quarterly In Service Test, the 1A

containment spray pump and its associated room cooler were stopped to facilitate

adding oil to the pump. About 1 - 3 minutes after restart of the pump and room cooler,

the room cooler tripped. Troubleshooting revealed the thermal overloads for the 1A

containment spray pump supply breaker had tripped. The thermal overloads were reset

and FNP-1-STP-16.1 was successfully completed. Operations personnel suggested

that this event was similar to an event which occurred on July 15, 2003, during the same

surveillance test. At the time of the July 2003 event, the 1A containment spray pump

room cooler had been running to support painting in the pump room when it was

stopped for the quarterly pump test. Approximately 1 - 3 minutes after starting the 1A

containment spray pump and room cooler, the room cooler tripped. The thermal

overloads were reset twice before FNP-1-STP-16.1 could be successfully completed.

Followup actions to the July 15, 2003 event involved tightening electrical connections

and post-maintenance testing of the room cooler, but not in the run/stop/hot restart

fashion in which it had failed.

Investigation into the similarity of the two events resulted in troubleshooting efforts on

April 30, 2004. These efforts determined that a degraded time delay relay was most

likely the cause for both events and Minor Departure 04-2760 was implemented on May

1, 2004, to correct the problem. This time, post-maintenance testing was conducted

satisfactorily in the run/stop/hot restart fashion. To assure operability, the 1B

Enclosure

7

containment spray pump room cooler was subsequently tested satisfactorily in the

run/stop/hot restart fashion. In addition, Design Change Request (DCR) M04-1-0060

was created to make the thermal overload configuration in the Unit 1 pump room coolers

the same as in Unit 2. This design change had been completed on both Unit 1

containment spray pump room coolers and was scheduled to be implemented on the

remaining Unit 1 pump room coolers in 2006. Further investigation by the licensee

concluded that the root cause evaluation for the July 15, 2003 event was inadequate;

resulting in a maintenance preventable functional failure (MPFF) of the 1A containment

spray pump room cooler on March 23, 2004. However, the team determined that the

degraded condition of the 1A containment spray pump room cooler rendered it

vulnerable to run/stop/hot restart scenarios that could be encountered during the

response to a large break LOCA. Such scenarios would involve: (1) a subsequent loss

of offsite power and re-sequencing loads on the emergency diesel generators; or (2) the

need to momentarily secure containment spray pumps/room coolers to facilitate the

transfer of emergency core cooling systems to the containment sump.

Analysis: This finding is more than minor because it affects the Barrier Integrity

Cornerstone attribute of Barrier Performance and impacted the cornerstone objective in

that tripping of the room cooler could result in loss of the 1A containment spray pump

safety function due to overheating. This finding is of very low safety significance

(Green) because the 1B containment spray pump and room cooler and all containment

coolers were available to ensure containment barrier integrity would be maintained in

the event of a large break LOCA or containment over pressure challenge.

Enforcement: 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, required that

measures shall be established to assure that significant conditions adverse to quality

are promptly identified. Contrary to the above, following the July 15, 2003 trip of the 1A

containment spray pump room cooler the licensee failed to identify a degraded time

delay relay. Consequently, a similar run/stop/hot restart trip of the room cooler

occurred on March 23, 2004. For the period between July 15, 2003, until corrected on

May 1, 2004, the degraded condition rendered the 1A containment spray pump room

cooler vulnerable to run/stop/hot restart scenarios that could be encountered during

the response to a large break LOCA. Because this finding is of very low safety

significance and has been entered into the licensees corrective action program (CR

2005109145), this violation is being treated as an NCV, consistent with Section VI.A of

the NRC Enforcement Policy: NCV 05000348/2005008-01, Failure to Identify 1A

Containment Spray Pump and Room Cooler Degraded Time Delay Relay.

(b) SSPS/7300 Troubleshooting

Introduction: A Green, NRC-identified NCV of 10 CFR Part 50, Appendix B, Criterion

XVI, was identified for failure to take corrective actions to preclude repetition of a

significant condition adverse to quality. Specifically, corrective actions taken to develop

a SSPS/7300 troubleshooting guideline following a Unit 2 SSPS/7300 troubleshooting-

related reactor trip on April 12, 2004, was inadequate to preclude the recurrence of

another SSPS/7300 troubleshooting-related event on April 28, 2005.

Enclosure

8

Description: On April 11, 2004, Unit 2 tripped due to a fault which unblocked the source

range high flux trip. SSPS/7300 troubleshooting resulted in two SSPS cards being

replaced and the unit was restarted. However, Unit 2 tripped again on April 12, 2004,

due to the same unblocking of the source range high flux trip. Subsequent

troubleshooting revealed that a different SSPS card was the source of the problem. The

licensee also determined that, as a contributing cause, troubleshooting activities

following the first trip did not use a rigorous troubleshooting methodology to identify and

validate the specific equipment failure and corrective action. Additionally, no formal

guidance for troubleshooting problems in the SSPS/7300 process channels existed.

Therefore, the exact equipment failure was not correctly identified and the problem

recurred. Corrective actions to prevent recurrence included development of formal

SSPS/7300 troubleshooting guidance.

A similar SSPS/7300 troubleshooting-related event occurred subsequently on April 28,

2005, when annunciators for the 1B Steam Generator Main Steam Line Delta P Alert

came into alarm. Based on the control board indications and previous history of failed

7300 cards, the licensee believed that a 7300 card had failed and entered TS 3.3.2,

LCO D for an inoperable 7300 channel. The required action for this condition was to

place the channel in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or be in Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and Mode 4

within 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. After placing the channel in the tripped condition, troubleshooting was

begun on the associated 7300 cards to identify the exact failure. The licensee had

determined that the 7300 cards were sending the proper signal to SSPS and concluded

that the current TS LCO may not be correct. Based on this information, the licensee

tested an input relay that was the interface between the 7300 and SSPS circuitry and,

on April 29, 2005, it was found to be satisfactory. Consequently, TS 3.3.2, LCO D was

exited and the licensee entered TS 3.3.2, LCO C for SSPS "A" Train. The required

action for this condition was to restore the train to operable status within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or be in

Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Troubleshooting on SSPS was subsequently completed,

revealing that a SSPS logic card had failed. After the logic card was replaced, and

SSPS tested satisfactorily, the licensee exited the LCO. (Note: The failure to follow TS

for an inoperable SSPS logic train was previously dispositioned as NCV

05000348/2005003002.)

The licensee identified a lack of procedural guidance to diagnose an alarm condition as

the root cause for the extended amount of time needed to troubleshoot the alarm

condition and associated TS concerns. Accordingly, a troubleshooting work order

sequence for such annunciator problems was incorporated into the SSPS/7300

troubleshooting guidance.

Analysis: This finding is more than minor because it affects the Mitigating Systems

Cornerstone attribute of equipment performance and adversely impacted the

cornerstone objective in that the SSPS/7300 troubleshooting guidance did not provide

the necessary steps to facilitate a timely (i.e., within the TS LCO) determination of a

SSPS/7300 process channel failure. This finding is of very low safety significance

because the B train of SSPS was maintained operable at all times.

Enclosure

Enforcement: 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, required that

measures shall be established to assure that significant conditions adverse to quality

are corrected to preclude repetition. Contrary to the above, the SSPS/7300

troubleshooting guideline developed as a corrective action for a Unit 2 SSPS/7300

troubleshooting-related reactor trip on April 12, 2004, was inadequate to preclude the

occurrence of another SSPS/7300 troubleshooting-related event on April 28, 2005.

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

licensees corrective action program (CR 2005109147), this violation is being treated as

a NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000364/2005008-02, Inadequate Corrective Action Results in Recurrence of a

SSPS/7300 Troubleshooting-Related Event.

(c) Radiation Monitor R-11 Failures

Introduction: A Green, NRC-identified finding (FIN) was identified for untimely resolution

of excessive air flow problems on the Unit 1 and Unit 2 Containment Air Particulate

Radiation Monitors (R-11). Excessive air flow through the moving filter paper caused

the monitor to become inoperable on numerous occasions since 1990. When R-11 was

out of service, the ability to detect low-level RCS leakage was degraded.

Description: After the licensee installed new paper drives in 1990, radiation monitor

R-11 experienced frequent paper drive malfunctions and pump trips. The licensee

determined that there was too much air flow through the sample lines. The sample air

flow for R-11 was originally designed for 10 cubic feet per minute (CFM) and the pumps

were sized accordingly. However, the paper drive vendor recommended a flow rate of

no more than 5 CFM to avoid paper drive related problems. Due to these problems,

radiation monitor R-11 was put on the MR (a)(1) list in 1995.

In order for R-11 to perform its TS function, at least 4 CFM air flow was required.

However, due to uncertainties in the flow measuring device, the flow rate must be set at

6 CFM or greater to ensure that the TS required 4 CFM passes through the filter paper.

On August 8, 1996, DCR 96-1-9059 was submitted to install a bypass line to reduce the

air flow through the filter paper to 6 CFM with the remaining 4 CFM bypassing the paper

drive/detector assembly. No analysis was performed to determine whether the flow rate

upstream of the detector could be reduced below the design rate of 10 CFM. The

design change was completed in December 1997 but, frequent pump trips and paper

drive problems due to excessive flow rate continued to be a problem. Also, with the new

bypass line installed, small fluctuations in pressure caused Hi/Lo air flow alarms. Root

Cause Investigation 2-98-338/1-98-328, Request for Engineering Assistance (REA)

99-2100, and REA 99-2121 were completed to evaluate R-11 pump-related problems.

The licensee concluded that more man-power intensive preventive maintenance tasks

(PMs) were required to keep R-11 functional (e.g., more frequent checks on pump drive

belts and filter paper status, stricter adherence to vendor lube requirements, etc.). The

new PMs were effective in addressing the symptoms and R-11 was removed from the

Maintenance Rule (a)(1) list in late 2000. However, because the licensee did not

develop any corrective actions to address the underlying problem of excessive air flow,

the team concluded that the new PMs were effectively a work-around.

Enclosure

10

Beginning in 2003, problems related to excessive air flow again became an issue as

documented in numerous CRs including 2003002541, 2004000192, 2004101110,

2005101978, 2005012025, 2005102065, 2005102457, 2005106984, 2005017050,

2005107120, and 2005107076. In August 2004, R-11 was put back on the MR (a)(1)

list. In August 2005, Request for Engineering Review C050882501 was submitted to

modify the system. This modification would eliminate the bypass line, reduce the

capacity of the sample pumps flow from 6 CFM to 2-3 CFM, and replace the flow

measurement device with a more accurate automated mass-flowmeter. These

modifications, which appeared to be an adequate solution, are scheduled to be

implemented in 2006.

Analysis: The team determined that the R-11 air flow related problems are a

performance deficiency in that the resultant impact to the instruments ability to perform

its TS required function was reasonably within the licensees ability to correct in a timely

manner. This finding is more than minor because it is associated with the RCS

Equipment and Barrier Performance Attribute of the Barrier Integrity Cornerstone and

adversely affects the cornerstone objective in that the ability to detect low-level RCS

leakage that may indicate pressure boundary degradation was reduced. This finding

could not be evaluated using the Significance Determination Process (SDP) in

accordance with IMC 0609 because the SDP for the RCS barrier only applied to a

degraded barrier; not the ability to detect a degraded barrier. Therefore, this finding was

reviewed by the regional management and determined to be of very low safety

significance (Green) because alternate methods of detecting low-level RCS leakage

were available when R-11 has been out of service.

Enforcement: No violation of TS or other NRC requirements occurred. This finding has

been entered into the licensees corrective action program (CR 2005109190) and is

identified as FIN 05000348,364/2005008-03, Untimely Resolution of Flow Problems on

Radiation Monitor R-11.

d. Assessment of Safety-Conscious Work Environment (SCWE)

(1) Inspection Scope

The team conducted interviews with randomly selected members of the plant staff,

including operations, maintenance, engineering, health physics, and emergency

preparedness personnel, to develop a general perspective of the SWCE at the site and

the willingness of personnel to use the CAP and the employee concerns program

(ECP). The interviews were also to determine if any conditions existed that would cause

employees to be reluctant to raise safety concerns. The team also reviewed the

licensees ECP, which provides an alternate method to the CAP for employees to raise

concerns and remain anonymous. The team interviewed the ECP Coordinator and

reviewed a select number of ECP reports completed since August 2003 to verify that

concerns were being properly reviewed and that identified deficiencies were being

resolved in accordance with the SNC Concerns Program Procedure, Revision 8.

Enclosure

11

(2) Assessment

The team concluded that licensee management emphasized the need for all employees

to identify and report problems using the appropriate methods established within the

administrative programs, including the CAP and ECP. These methods were readily

accessible to all employees. Licensee management encouraged employees to promptly

identify nonconforming conditions. Based on discussions conducted with a sample of

plant employees from various departments, the team determined that the site staff felt

free to raise issues and felt that management wanted issues placed into the CAP for

resolution. The staff members also believed that feedback was good when using the

CAP and the ECP, and that they were kept up to date on identified issues. The team

noted that, for the ECP files they had reviewed, CRs were initiated in the CAP for any

substantiated condition adverse to quality that had been identified in the file. The team

also did not identify any reluctance to report safety concerns.

4OA6 Management Meetings Including Exit

The team presented the inspection results to Mr. Todd Youngblood and other members

of licensee management on August 25, 2005, who acknowledged the findings. The

team also confirmed that proprietary information was not provided or examined during

the inspection.
