SUBJECT:

HOPE CREEK GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000354/2006005

Dear Mr. Levis:

On December 31, 2006, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Hope Creek Generating Station. The enclosed inspection report documents the inspection results, which were discussed on January 5, 2007, with Mr. G. Barnes and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

The report documents one NRC-identified finding and two self-revealing findings of very low safety significance (Green). This report also documents, in Enclosure 2, one finding of very low security significance (Green) as determined by the Physical Protection Significance Determination Process. The deficiency was promptly corrected or compensated for, and the plant was in compliance with applicable physical protection and security requirements within the scope of this inspection before the inspectors left the site. These findings were determined to involve violations of NRC requirements. Additionally, licensee-identified violations which were determined to be of very low safety significance are listed in this report. However, because of the very low safety significance and because they are entered into your corrective action WARNING: Violation of Section 147 of the Safeguards information determination made by:

Atomic Agency Act, Safeguards Information, Name/Title James M. Trapp, Chief is subject to civil and criminal penalties. Organization RI/DRS/PSB1 Basis DG-SG-1: (300) Physical Protection Program Signature /RA/

Date 01/31/07 Mr. William Levis 2 program, the NRC is treating these findings as non-cited violations (NCVs) consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, 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 I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Hope Creek Generating Station.

SUMMARY OF FINDINGS

IR 05000354/2006005; 10/01/2006 - 12/31/2006; Hope Creek Generating Station; Maintenance

Effectiveness, Other Activities.

The report covered a 13-week period of inspection by resident inspectors, and announced inspections by a regional operations inspector and a regional senior health physics inspector.

Three Green non-cited violations (NCVs) were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter (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 NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green.

A self-revealing non-cited violation of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when maintenance personnel lifted an energized lead (wire) that inadvertently tripped the B control room chiller during maintenance on the B control area battery room exhaust fan. PSEGs corrective actions included revising the maintenance planning development procedure and conducting a review of other relay replacement preventative maintenance procedures to identify weaknesses similar to those discovered during the investigation of this issue.

The inspectors determined the failure to provide appropriate procedures, drawings, or instructions for the replacement of a relay constituted a performance deficiency and a finding. The finding is more than minor because it is associated with the procedure quality attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences.

The inspectors conducted a Phase 1 SDP screening and determined the issue to be of very low safety significance (Green). The finding has a cross-cutting aspect in the area of human performance because personnel proceeded in the face of uncertainty or unexpected circumstances by deciding to lift two leads without understanding the effect that action would have on safety-related equipment. (Section 1R12)

Green.

A self-revealing non-cited violation of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when the safety auxiliaries cooling system (SACS) throttle valve to the C emergency diesel generator (EDG) was found out of its required position on August 11, 2006.

PSEGs corrective actions included performing a flow balance on the EDG to correct SACS valve positions and implementing a modification to the SACS to increase available cooling flow to the EDGs. The finding is self-revealing, rather than licensee-identified, because the inspectors communicated concerns of unusually high lube oil temperatures during summer conditions to PSEG personnel that were not confirmed by PSEG for several months due to repetitive iii deferrals of corrective action orders to evaluate the condition. PSEG had surveillance test data that demonstrated that all of the EDGs were exhibiting higher than normal lube oil temperatures during summer months and thus could reasonably have discovered the configuration control error before high summer temperatures challenged the capability of the EDG.

The inspectors determined that positioning equipment contrary to PSEGs configuration control and safety tagging procedures was a performance deficiency and a finding. The finding is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors conducted a Phase 1 SDP screening and determined the issue to be of very low safety significance (Green). The finding had a cross-cutting aspect in the area of human performance because self and peer checks were not used effectively to verify the correct position of the SACS throttle valve following maintenance activities. (Section 4OA2)

C

Green.

The inspectors identified a non-cited violation of 10 CFR 50 Appendix B,

Criterion XVI, Corrective Action, when lube oil temperature exceeded the procedural limit of 170 degrees F on the B EDG during a surveillance test on July 31, 2006. PSEG determined that a throttle valve in the SACS was not in the required position, which caused a reduction of cooling flow to the EDG lube oil cooler. The finding is NRC-identified because the inspectors communicated concerns of unusually high lube oil temperatures during summer conditions to PSEG personnel that were not confirmed by PSEG for several months due to repetitive deferrals of corrective action orders to identify the condition. PSEGs corrective actions included performing a flow balance on the EDG to correct SACS valve positions and implementing a modification to SACS to increase available cooling flow to the EDGs.

The finding is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors conducted a Phase 1 SDP screening and determined the issue to be of very low safety significance (Green). The finding has a cross-cutting aspect in the area of problem identification and resolution because PSEG did not promptly identify deficiencies that caused higher than expected temperatures in EDG lube oil systems. (Section 4OA2)

Licensee Identified Violations

Violations of very low safety significance, that were identified by PSEG have been reviewed by the inspectors. Corrective actions taken or planned by PSEG have been entered into PSEGs corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.

1R06 Flood Protection Measures

.1 Internal Flooding

a. Inspection Scope

(1 sample)

The inspectors reviewed selected risk-important plant design features and PSEG procedures intended to protect the plant and its safety-related equipment from internal flooding events. The inspectors focused on mitigation strategies and equipment in the A safety auxiliaries cooling system (SACS) pump room. The inspectors reviewed flood analysis and design documents, including the updated final safety analysis report (UFSAR), engineering calculations, and abnormal operating procedures. The

inspectors observed the condition of wall penetrations, watertight doors, flood alarm switches, and drains to assess their readiness to contain flow from an internal flood in accordance with the design basis. In addition, the inspectors walked down the A SACS room and adjacent rooms in the reactor building to assess potential flooding vulnerabilities.

b. Findings

No findings of significance were identified.

1R11 Licensed Operator Requalification Program

.1 Requalification Activities Review By Resident Staff

a. Inspection Scope

(1 sample)

The resident inspectors observed one annual licensed operator requalification simulator scenario on October 12, 2006, to assess operator performance and training effectiveness. The scenario involved a loss of two inverters and a recirculation pump seal leak into containment with a failed reactor jet pump. The inspectors assessed simulator fidelity and observed the simulator instructors critique of operator performance. The inspectors also observed control room activities with emphasis on identified areas for improvement. Finally, the inspectors reviewed applicable documents associated with licensed operator requalification as listed in the attachment.

b. Findings

No findings of significance were identified.

.2 Biennial Review

a. Inspection Scope

(1 sample)

The following inspection activities were performed using NUREG-1021, Rev. 9, Operator Licensing Examination Standards for Power Reactors, Inspection Procedure

===71111.11, Licensed Operator Requalification Program, NRC Manual Chapter 0609, Appendix I, Operator Requalification Human Performance Significance Determination Process (SDP), and 10 CFR 55.46 Simulator Rule as acceptance criteria.

The inspectors reviewed documentation of operating history since the last requalification program inspection. The inspectors also discussed facility operating events with the resident staff. Documents reviewed included NRC inspection reports, plant performance insights, licensee event reports (LERs), and corrective action program notifications that involved human performance issues for licensed operators to ensure that operational events were not indicative of possible training deficiencies. Documents reviewed are listed in the attachment.

The inspectors reviewed four exam sets (i.e., weeks 1, 2, 3 and 4) for simulator scenarios and two weeks of job performance measures (JPMs) administered during this current exam cycle to ensure the quality of these exams met or exceeded the criteria

established in the Examination Standards and 10 CFR 55.59. The inspectors compared these four scenario sets for repeatability. The inspectors also compared the practice scenarios used just prior to the exam administration to ensure no exam security issues were present.

The inspectors observed the administration of operating examinations to operating shifts E and C. The operating examinations consisted of two simulator scenarios and one set of five JPMs administered to each individual. The inspectors observed the training department staff administer four simulator scenarios, four simulator JPMs, and four in-plant JPMs.

The inspectors also reviewed all comprehensive written exams administered for the current requalification cycle for quality and exam security issues.

Conformance with Simulator Requirements Specified in 10 CFR 55.46 The inspectors observed simulator performance during the conduct of the examinations and reviewed discrepancy reports to verify compliance with the requirements of 10 CFR 55.46. The inspectors also reviewed:

  • The list of open and closed Simulator Deficiency Reports (SDRs). The 34 open SDRs were reviewed to determine if deficiencies are being adequately prioritized and are being corrected in a timely manner. One SDR was reviewed in detail for proper resolution of issues.
  • The controlling documents to ensure simulator capability, configuration control, and testing meet the guidance in ANSI/ANS 3.5, 1985.
  • The completed simulator test schedule for 2004-2006. All annual transient tests performed in 2004, 2005, and 2006, as well as all malfunction simulator tests performed in 2006 were reviewed. The inspectors confirmed that the annual performance tests were being performed at the appropriate frequency and that the tests compared the simulator data to actual plant data or best estimate data as appropriate.

Conformance with Operator License Conditions

  • Remediation training records were reviewed. The adequacy of remedial training was assessed by review of remediation packages for two examples of biennial written exam failures and twenty examples of segment exam failures and simulator or JPM performance deficiencies.
  • Proficiency watch-standing and reactivation records were reviewed. One licensed operator reactivation record was reviewed as well as a random sample watch-standing documentation (i.e., all staff license individuals) for time on shift to verify currency and conformance with the requirements of 10 CFR 55.

Licensees Feedback System The inspectors interviewed instructors, training/operations management personnel, and operators for feedback regarding the implementation of the licensed operator

requalification program to ensure the requalification program was meeting their needs and responsive to their noted deficiencies/recommended changes. The inspectors reviewed 20 individual feedback forms.

Review of Licensee Requalification Exam Results On December 21, 2006, the inspectors conducted an in-office review of licensee requalification exam results. These results included the annual operating tests and Comprehensive Written Exams administered this year. The inspection assessed whether pass rates were consistent with the guidance of NRC Manual Chapter 0609, Appendix I, Operator Requalification Human Performance Significance Determination Process (SDP). The inspectors verified that:

  • Crew failure rate on the dynamic simulator was less than 20%.

(Failure rate was 0%.)

  • Individual failure rate on the dynamic simulator test was less than or equal to 20%. (Failure rate was 0%.)
  • Individual failure rate on the walkthrough test (JPMs) was less than or equal to 20%. (Failure rate was 0%.)
  • Individual failure rate on the comprehensive written exam was less than or equal to 20%. (Failure rate was 2%.)
  • More than 75% of the individuals passed all portions of the exam. (98% of the individuals passed all portions of the exam.)

b. Findings

No findings of significance were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

=

The inspectors reviewed the three samples listed below for items such as:

(1) appropriate work practices;
(2) identifying and addressing common cause failures;
(3) scoping in accordance with 10 CFR 50.65(b) of the maintenance rule (MR);
(4) characterizing reliability issues for performance;
(5) trending key parameters for condition monitoring;
(6) charging unavailability for performance;
(7) classification and reclassification in accordance with 10 CFR 50.65(a)(1) or (a)(2); and
(8) appropriateness of performance criteria for structures, systems, and components (SSCs)/functions classified as (a)(2) and/or appropriateness and adequacy of goals and corrective actions for SSCs/functions classified as (a)(1). In addition, the inspectors specifically reviewed events where ineffective equipment maintenance had resulted in invalid automatic actuations of engineered safeguards systems affecting the operating units. Documents reviewed are listed in the attachment. Items reviewed included the following:

C B control room chiller and ventilation train trip on September 7, 2006;

C C service water traveling screen shear pin failure on October 21, 2006; and C B emergency diesel generator starting air failure on October 13, 2006.

b. Findings

Introduction:

A Green self-revealing non-cited violation of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings," was identified when maintenance technicians lifted an energized lead (wire) while working on the B control area battery room exhaust fan and caused an inadvertent trip of the B control room chiller (BK-400).

Description:

On September 7, 2006, maintenance technicians lifted an energized lead in accordance with the work order instructions for a 22-year relay replacement preventive maintenance activity on the B control area battery room exhaust fan (BV-410) control logic. The lifting of the lead also removed power from the low flow circuitry for the B control equipment room supply fan (BV-407), which caused the BV-407 to trip.

The trip of the BV-407 resulted in a trip of the B control room chiller and ventilation train.

The BV-410 relay replacement work order referenced a system schematic and did not reference detailed wiring diagrams. When assembling the original work order for the relay replacement, PSEG planners did not reference plant drawings that indicated that additional equipment would be impacted when lifting the energized lead associated with the H1GK-1KY-1D-C-483-1V0413 (GK-V0413) relay for the BV-410 fan.

Prior to lifting the energized lead, maintenance technicians identified the work plan was inadequate because an unknown additional wire was located on the energized lead connection point. The maintenance supervisor and technicians reviewed additional drawings that were not included in the work package, but were unable to positively identify the additional lead because the drawings were illegible. However, the team decided not to revise the work plan and proceeded with the relay replacement based on experience with similar relay panel wiring. The 'B' control room chiller subsequently tripped when the additional lead was lifted.

Analysis:

The inspectors determined that the failure to provide appropriate procedures for the replacement of the GK-V0413 relay constituted a performance deficiency and a finding. The finding is more than minor because it is associated with the procedure quality attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences.

In accordance with NRC Inspection Manual Chapter 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," the inspectors conducted a Phase 1 screening and determined the finding to be of very low safety significance (Green). The finding was not a design or qualification deficiency, did not represent a loss of system safety function, did not represent an actual loss of safety function of a single train for greater than its Technical Specification Allowed Outage Time, did not represent an actual loss of safety function of one or more non-Technical Specification trains of equipment designated as risk significant per 10 CFR 50.65, for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and did not screen as potentially risk significant due to external events. The finding has a cross-cutting aspect in the area of human performance because personnel proceeded in the face of uncertainty or unexpected circumstances

by deciding to lift two leads without positively knowing the effect that action would have on safety-related equipment.

Enforcement:

10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances. Contrary to the above, PSEG did not provide appropriate guidance for the replacement of the GK-V0413 relay which resulted in three hours of unplanned availability of the B control room chiller and ventilation train on September 7, 2006.

PSEGs corrective actions included revising the maintenance planning development procedure to specifically require review of circuits for daisy chained circuits when lifting leads, developing a technical review template to be used in reviewing all 22-year relay replacement preventative maintenance (PM) orders and planning library copies, and conducting a review of a sampling of other 22-year relay replacement PMs for similar oversights. Because this finding is of very low safety significance and has been entered into PSEGs corrective action program (evaluation 70058747), this finding is being treated as a non-cited violation consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000354/2006005-01, Unplanned Trip of the B Control Room Chiller and Ventilation Train.

1R13 Maintenance Risk Assessments and Emergent Work Control

a. Inspection Scope

(5 samples)

The inspectors reviewed on-line risk management evaluations through direct observation and document reviews for the following five configurations:

C Emergent unavailability of the B service water (SW) pump during the planned maintenance on the D SW pump on October 3, 2006 (a yellow risk condition);

C 1AD483 inverter troubleshooting and re-alignment on October 11-12, 2006; C Planned maintenance on A EDG ventilation trains on October 12-13, 2006; C Emergent maintenance on the 10D420 125 V DC bus on December 8, 2006; and C PSEG risk management actions associated with continued plant operation with a steam leak on the 3A feedwater heater extraction steam line on November 18, 2006.

The inspectors reviewed the applicable risk evaluations, work schedules and control room logs for these configurations to verify that concurrent planned and emergent maintenance and test activities did not adversely affect the plant risk already incurred with these configurations. PSEGs risk management actions were reviewed during shift turnover meetings, control room tours, and plant walkdowns. The inspectors also used PSEGs on-line risk monitor (Equipment Out-Of-Service workstation) to gain insights into the risk associated with these plant configurations. Finally, the inspectors reviewed notifications documenting problems associated with risk assessments and emergent work evaluations. Documents reviewed are listed in the attachment.

b. Findings

No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scope

(4 samples)

The inspectors reviewed four operability determinations for degraded or non-conforming conditions associated with:

C C and D suppression pool to drywell vacuum breakers indicated partially open on October 19, 2006; C high pressure coolant injection suppression pool suction check valve inservice testing methodology issue on November 7, 2006; C B technical support center and 1E panel room chiller on November 24, 2006; and C D emergency diesel generator output breaker inoperability due to card failure on November 27, 2006.

The inspectors reviewed the technical adequacy of the operability determinations to ensure the conclusions were justified. The inspectors also walked down accessible equipment to corroborate the adequacy of PSEGs operability determinations.

Additionally, the inspectors reviewed other PSEG identified safety-related equipment deficiencies during this report period and assessed the adequacy of their operability screenings. Notifications and documents reviewed are listed in the attachment.

b. Findings

No findings of significance were identified.

1R17 Permanent Plant Modifications

a. Inspection Scope

(1 sample)

The inspectors reviewed work performed to address vibration on the B reactor recirculation pump prior to pump replacement in April 2006. The work included installing and removing balance weights, modifying vibration probe locations, and machining the pump coupling. The inspectors reviewed the maintenance and design change processes to ensure they were appropriately followed and the pump design basis was maintained.

b. Findings

No findings of significance were identified.

1R19 Post-Maintenance Testing

a. Inspection Scope

(5 samples)

The inspectors reviewed the five post-maintenance tests listed below to verify that procedures and test activities ensured system operability and functional capability. The inspectors reviewed test procedures to verify the procedure adequately tested the safety functions that may have been affected by the maintenance activity and the acceptance criteria in the procedure were consistent with the Updated Final Safety Analysis Report

(UFSAR) and other design or license basis documentation. The inspectors also witnessed the test or reviewed the test data to verify test results adequately demonstrated restoration of the affected safety functions. Documents reviewed are listed in the attachment.

  • Work order (WO) 30105764/30120261, Replacement of D service water spray wash booster pump and motor;
  • WO 30135090, Inspection and weld repair of valve 1-BE-V032.

b. Findings

No findings of significance were identified.

1R22 Surveillance Testing

a. Inspection Scope

(4 samples)

The inspectors witnessed four surveillance tests and/or reviewed test data of selected surveillance tests listed below to verify that the test met the requirements of the Technical Specifications, UFSAR, and station procedures. The inspectors also determined whether the testing effectively demonstrated that the structures, systems, and components were operationally ready and capable of performing their intended safety functions. Documents reviewed are listed in the attachment.

  • WO 50099007, suppression pool to drywell vacuum breaker monthly operability test on October 19, 2006;
  • WO 50097983, G diesel fuel oil transfer pump inservice test on November 3, 2006.

b. Findings

No findings of significance were identified.

1R23 Temporary Plant Modifications

a. Inspection Scope

(1 sample)

The inspectors reviewed a temporary plant modification (T-Mod 06-018) associated with the 00K107 and 10K107 station air compressors. The modification bypassed the aftercooler outlet temperature trip function for each compressor. The inspectors verified the modification was consistent with the design and licensing bases of the instrument air system and that the performance capability of the system was not degraded by the modification. The inspectors reviewed documents to verify PSEG followed their processes for implementing temporary modifications on plant SSCs. In addition, the

inspectors verified the modified equipment alignment through control room instrumentation and plant walkdowns of accessible portions of the affected equipment.

The inspectors also reviewed notifications documenting problems associated with equipment affected by temporary modifications. Documents reviewed are listed in the attachment.

b. Findings

No findings of significance were identified.

Cornerstone: Emergency Preparedness

1EP6 Drill Evaluation

a. Inspection Scope

(1 sample)

Resident inspectors evaluated the conduct of a simulator examination scenario on October 12, 2006, to identify any weaknesses and deficiencies in classification, notification, and protective action recommendation (PAR) development activities. The inspectors observed emergency response operations in the simulated control room to verify that event classification and notifications were completed in accordance with the Hope Creek Event Classification Guide. The inspectors also observed PSEGs critique of the examination to compare any inspector-observed weakness with those identified by PSEG personnel in order to verify whether PSEG was properly identifying weaknesses.

b. Findings

No findings of significance were identified.

RADIATION SAFETY

Cornerstone: Public Radiation Safety

2PS1 Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems (71122.01)

a. Inspection Scope

(11 samples)

The inspectors reviewed the most current Radiological Effluent Release Report to verify that the program was implemented as described in Radiological Effluent Technical Specification/Offsite Dose Calculation Manual (RETS/ODCM); reviewed the report for significant changes to the ODCM and to radioactive waste system design and operation; determined whether the changes to the ODCM were made in accordance with Regulatory Guide 1.109 and NUREG-0133 and were technically justified and documented; determined whether the modifications made to radioactive waste system design and operation changed the dose consequence to the public; verified that technical and/or 10 CFR 50.59 reviews were performed when required; and, determined whether radioactive liquid and gaseous effluent radiation monitor setpoint calculation methodology changed since completion of the modifications.

The inspectors determined that anomalous results reported in the current Radiological Effluent Release Report were adequately resolved. The inspectors reviewed RETS/ODCM to identify the effluent radiation monitoring systems and its flow measurement devices; reviewed effluent radiological occurrence performance indicator incidents for onsite follow-up; reviewed PSEG self assessments, audits, and licensee event reports that involved unanticipated offsite releases of radioactive material; and, reviewed the UFSAR description of all radioactive waste systems.

The inspectors walked down the major components of the gaseous and liquid release systems (e.g., radiation and flow monitors, demineralizers and filters, tanks, and vessels) to observe current system configuration with respect to the description in the UFSAR, ongoing activities, and equipment material condition.

The inspectors reviewed several radioactive liquid and gaseous waste release permits, including the projected doses to members of the public.

The inspectors reviewed the records of any abnormal releases or releases made with inoperable effluent radiation monitors and reviewed PSEGs actions for these releases to ensure an adequate defense-in-depth was maintained against an unmonitored, unanticipated release of radioactive material to the environment.

The inspectors reviewed changes made by PSEG to the ODCM as well as to the liquid or gaseous radioactive waste system design, procedures, or operation since the last inspection. For each system modification and each ODCM revision that impacted effluent monitoring or release controls, the inspectors reviewed PSEGs technical justification and determined whether the changes affected PSEGs ability to maintain effluents as low as is reasonable achievable (ALARA) and whether changes made to monitoring instrumentation resulted in a non-representative monitoring of effluents.

The inspectors reviewed a selection of monthly, quarterly, and annual dose calculations to ensure that PSEG had properly calculated the offsite dose from radiological effluent releases and to determine if any annual RETS/ODCM (i.e., Appendix I to 10 CFR Part 50 values) were exceeded and, if appropriate, issued a Performance Indicator (PI)report if any quarterly values were exceeded.

The inspectors reviewed air cleaning system surveillance test results and PSEG specific methodology to ensure that the system is operating within PSEGs acceptance criteria.

The inspectors also reviewed surveillance test results and methodology PSEG uses to determine the stack and vent flow rates and verified that the flow rates are consistent with RETS/ODCM or UFSAR values.

The inspectors reviewed the records of any abnormal releases made with inoperable radiation monitors, and determined that there were no releases of this type since the last inspection of this area. The inspectors also verified that PSEGs records of spills, leaks and other unusual occurrences were properly maintained in accordance with 10 CFR 50.75(g).

The inspectors reviewed records of radiation monitoring system (RMS) instrument calibrations performed since the last inspection for each point of discharge effluent radiation monitor and flow measurement device and reviewed any completed system modifications and the current effluent radiation monitor alarm setpoint value for

agreement with RETS/ODCM requirements. The inspectors also reviewed calibration records of radiation measurement (i.e., counting room) instrumentation associated with effluent monitoring and release activities and reviewed quality control records for the radiation measurement instruments.

The inspectors reviewed the results of the interlaboratory comparison program to verify the quality of radioactive effluent sample analyses performed by PSEG; reviewed the PSEGs quality control evaluation of the interlaboratory comparison test and associated corrective actions for any deficiencies identified; and reviewed the results from the PSEGs quality assurance audits and determined that PSEG met the requirements of the RETS/ODCM.

The inspectors reviewed PSEGs licensee event reports, special reports, audits, and self assessments related to the RETS/ODCM program performed since the last inspection.

The inspectors determined that identified problems were entered into the corrective action program for resolution. The inspector also reviewed problem notifications affecting RETS/ODCM.

b. Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

.1 Review of Items Entered into the Corrective Action Program:

As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into PSEG's corrective action program. This was accomplished by reviewing the description of each new notification and attending daily management review committee meetings.

Documents reviewed are listed in the attachment.

.2 Semi-Annual Review to Identify Trends

a. Inspection Scope

(1 sample)

As required by Inspection Procedure 71152, Identification and Resolution of Problems, the inspectors performed a review of PSEGs corrective action program (CAP) and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment and corrective maintenance issues, but also considered the results of daily inspector CAP item screening discussed in Section 4OA2.1. The review also included issues documented outside the normal CAP in system health reports, corrective maintenance work orders, component status reports, site monthly meeting reports and maintenance rule assessments. The inspectors review nominally considered the six-month period of June 1, 2006, through November 30, 2006, although some examples expanded beyond those dates when the scope of the trend warranted. The inspectors specifically trended engineering program and corrective action program effectiveness. The inspectors compared and contrasted their results with the results contained in Hope Creeks latest monthly Business Plan Performance Reports. Corrective actions associated with a sample of the issues identified in PSEGs performance indicator were reviewed for adequacy. Documents reviewed are listed in the attachment.

b. Assessment and Observations No findings of significance were identified.

The inspectors concluded that PSEG's identification of engineering problems was consistent with those identified by inspectors over the period reviewed. PSEGs evaluations were of sufficient scope and depth to address identified problems. The inspectors concluded that corrective actions were adequate in addressing engineering and corrective action program product quality.

.3 Annual Sample: Operations Excellence Plan

a. Inspection Scope

(1 sample)

The inspectors reviewed PSEGs actions related to the Hope Creek Operations Excellence Plan that was examined during the NRCs special inspection of the safety conscious work environment (SCWE), Inspection Report 05000272; 311/2006012 and

===05000354/2006011, dated July 31, 2006. In that report, the NRC noted that although improvements to the work environment at Salem and Hope Creek were substantial and sustainable, PSEG had missed some opportunities to address negative perceptions of the work environment in the Hope Creek Shift Operations work group. Further, the NRC observed that PSEGs plan to address these perceptions, the Hope Creek Operations Excellence Plan, did not initially include detailed analysis of survey and assessment results. In response, PSEG made adjustments to the plan to include analysis and actions for the survey and assessment results.

The NRCs Mid-Cycle Performance Review letter for Hope Creek, dated August 31, 2006, stated that the NRC intended to continue to monitor performance in the SCWE during baseline inspections. Additionally, the letter stated that the NRC intended to

review actions from the Operations Excellence Plan, as tracked in the corrective action program and intended to further improve the work environment in the operations work group, through a baseline problem identification and resolution sample inspection.

During this review, the inspectors reviewed corrective action program notifications, supporting documentation, and discussed the actions with Hope Creek personnel.

b. Findings and Observations

No findings of significance were identified.

The inspectors determined that PSEG had made progress on a number of actions described in the Hope Creek Operations Excellence Plan. These actions were intended to improve the work environment and workers perceptions, and covered such areas as overtime mitigation, succession planning, departmental communication, and accountability.

The inspectors discussed the actions with several Hope Creek personnel. All of the personnel interviewed stated that they felt free to raise safety concerns and they believed that plant equipment performance had improved during the past year. Many of those interviewed indicated that progress had been made on the items in the Operations Excellence Plan, and the overall work environment had improved over the past year or two. However, others perceived that some aspects of the work environment had not improved and were concerned about both the rate of attrition in the operations department and some communications issues between management and staff.

The inspectors concluded that PSEG had made adequate progress on the Hope Creek Operations Excellence Plan; however, there remained a range of perceptions among operations personnel on the progress to date. The inspectors observed that the Operations Excellence Plan remains a living document with a number of ongoing actions intended to further improve the work environment.

.4 (Closed) URI 05000354/2006004-03, Elevated Emergency Diesel Generator Lube Oil

Temperatures

a. Inspection Scope

On July 31, 2006, during a surveillance test of the B emergency diesel generator (EDG), equipment operators recorded lube oil temperatures at 172 degrees F. This temperature was 2 degrees above the vendor recommended limit for lube oil temperature, 170 degrees F, which was also the acceptance criteria in the surveillance test procedure. On August 10, 2006, PSEG determined that the safety auxiliaries cooling system (SACS) supply valve to the 'B' EDG heat exchangers was incorrectly throttled to a position that reduced the amount of SACS flow to the heat exchangers.

PSEG performed a past operability assessment of the B EDG (notification 20293502)and determined that the B EDG remained operable from August 8, 2005, through August 10, 2006. PSEG also found a SACS valve in an incorrectly throttled position on the C EDG on August 11, 2006. This issue was unresolved pending PSEG's completion of applicable evaluations and inspector review of PSEGs past-operability evaluations of the EDGs and evaluations associated with the apparent cause and extent of condition of the configuration control issues. The inspectors completed the review of

PSEGs evaluations and concluded there were two findings associated with the issue.

This URI is closed.

b. Findings

(.1) Mispositioned Valve Results in Reduced Cooling Flow to the C Emergency Diesel Generator

Introduction:

A Green self-revealing non-cited violation of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when a SACS throttle valve to the C EDG was found out of its required position on August 11, 2006.

Description:

On July 31, 2006, PSEG equipment operators observed that lube oil temperatures on the B EDG exceeded the procedural limit of 170 degrees F during a surveillance test. PSEG investigated the issue and found that a SACS throttle valve was mispositioned such that cooling water flow was reduced to the B EDG. On August 10, 2006, PSEG performed a flow balancing procedure to optimize flow to the B EDG and position the SACS throttle valve to its correct position. Additionally, PSEG increased the amount of SACS flow available to the EDGs by implementing a temporary modification that throttled a normally full-open valve to the residual heat removal (RHR) heat exchangers on August 8, 2006. This throttling reduced the amount of excess cooling to the RHR heat exchanger and made more coolant available to the EDGs. The temporary modification was inspected and documented in NRC Integrated Inspection Report 05000354/2006004 in Section 1R23. The temporary modification was made a permanent plant modification during this inspection period.

On August 11, 2006, PSEG performed flow balancing on the C EDG. The SACS throttle valve to the C EDG was found to be 2 3/4 turns open instead of the required 4 turns open. Following an engineering evaluation, PSEG determined that the B and C EDGs were operable. PSEG reviewed past operability using service water temperature data from August 8, 2005, to August 10, 2006. PSEG determined that the EDGs remained operable through the period. PSEG also concluded that flow balancing tests on the A or D EDGs were not necessary because surveillance test data indicated satisfactory SACS flow.

PSEG evaluated the mispositioning event on the C EDG and determined that the valve was likely mispositioned following work clearance activities on January 11, 2006. The review identified that temperature trends through the EDG heat exchanger changed after the work activity in January 2006 such that the measured temperature difference across the heat exchanger changed from approximately 17 degrees F to approximately 26 degrees F. PSEG could not find records of the work clearance or which individuals were involved in the valve positioning. PSEG identified the most likely cause to be that an equipment operator incorrectly positioned the valve and that the concurrent verifier failed to identify the improper valve position. PSEG configuration control and safety tagging procedures require that all valve manipulations be conducted in accordance with work control documents that identify the proper position of the valve to be manipulated.

Analysis:

The inspectors determined that the positioning of components contrary to PSEGs configuration control and safety tagging procedures was a performance deficiency and a finding. The finding is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences.

In accordance with Inspection Manual Chapter (IMC) 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, the inspectors conducted a Phase 1 SDP screening and determined the issue to be of very low safety significance (Green). The finding was not a design or qualification deficiency, did not represent a loss of system safety function, did not represent an actual loss of safety function of a single train for greater than its Technical Specification Allowed Outage Time, did not represent an actual loss of safety function of one or more non-Technical Specification trains of equipment designated as risk significant per 10 CFR 50.65, for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and did not screen as potentially risk significant due to external events. The finding has a cross-cutting aspect in the area of human performance because self and peer checks were not used effectively to verify the correct position of the SACS throttle valve.

Enforcement:

10 CFR 50 Appendix B, Criterion V, "Instructions, Procedures, and Drawings," states, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, and drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, equipment operators positioned valves contrary to the instructions in PSEG procedure SH.OP-AP.ZZ-0015, Safety Tagging Operations, on January 11, 2006, resulting in reduced SACS flow to the C EDG. The valves remained in the incorrect position until August 11, 2006. PSEG performed flow balancing procedures on the C EDG on August 11, 2006, and established the correct configuration and SACS flow to the EDG. Because this finding is of very low safety significance and has been entered into the corrective action program in notification 20293067, this violation is being treated as a NCV, consistent with section VI.A of the NRC Enforcement Policy. (NCV 05000354/2006005-02, Mispositioned Valve Results in Reduced Cooling Flow to the C Emergency Diesel Generator)

(.2) High Temperature Condition on B Emergency Diesel Generator Not Fully Identified in a Timely Manner

Introduction:

The inspectors identified a Green non-cited violation of 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, when lube oil temperature exceeded the procedural limit of 170 degrees F on the B EDG during a surveillance test on July 31, 2006.

Description:

On August 8, 2005, PSEG equipment operators observed lube oil temperatures on the D EDG at 168 degrees F during the monthly surveillance test. An evaluation (70049720) was performed by the system engineer to analyze the issue. PSEG concluded that the temperatures observed were expected for summer conditions based on a review of data from surveillance

tests performed over the past four years during the month of August. A second evaluation (70049822) was created on August 8, 2005, to evaluate the adequacy of the vendor-recommended maximum operating lube oil temperature of 170 degrees F. The vendor continued to recommend 170 degrees F as the maximum operating temperature. PSEG concurred with the conclusion and maintained the lube oil maximum temperature at 170 degrees F.

On December 15, 2005, after reviewing the evaluations from August 8, 2005, NRC inspectors questioned PSEG on the content of the evaluations.

Specifically, data from surveillance tests showed that EDG lube oil temperatures sometimes approached technical specification limiting conditions when service water (SW) and SACS temperatures were at moderate values on all four EDGs.

The inspectors questioned past operability of the four EDGs and whether the EDGs would exceed design lube oil temperatures during higher design basis service water and SACS temperature conditions.

Upon review of the questions, PSEG found that there was an unexpected difference between actual EDG lube oil temperatures and those that were predicted in design SACS heat load calculations. PSEG wrote notification 20265096 to examine the effects of SACS temperature on EDG lube oil temperature. PSEG concluded the EDGs remained operable because SW temperatures were low during the winter months, temperature limits were challenged only during the warmest days of summer, and the EDGs have passed all surveillance tests to date. Evaluation 70052404 was created to address the discrepancy between the design calculations and actual field measurements. PSEG created corrective action plans to perform a thermal performance test of the heat exchangers on one EDG and then create a thermal performance model of the EDG heat exchangers using the data obtained from the performance test. These corrective actions were originally due on March 30, 2006, but were moved to June 30, 2006, based on an engineering recommendation to obtain data when SACS was at higher temperatures. On June 30, 2006, data was acquired by PSEG, but the due date for the analysis of the data and modeling was extended to November 29, 2006.

On July 31, 2006, during a surveillance test of the B EDG, equipment operators recorded lube oil temperatures at 172 degrees F. This temperature was 2 degrees above the vendor recommended limit for lube oil temperature, 170 degrees F, which was the acceptance criteria in the surveillance test procedure.

A subsequent engineering evaluation by PSEG determined that the actual vendor recommended temperature limit was 175 degrees F and that 170 degrees F was the recommended alarm set-point based on a nominal 4 degrees instrument accuracy. PSEG also determined that the 175 degrees F limit was a nominal value based on the use of vendor supplied, skid-mounted temperature instruments. On August 10, 2006, PSEG determined that the SACS supply valve to the 'B' EDG heat exchangers was incorrectly throttled to a position that reduced the amount of SACS flow to the heat exchangers. PSEG performed a past operability assessment of the B EDG (notification 20293502) and determined that the B EDG remained operable from August 8, 2005, through August 10, 2006. PSEG also found a SACS valve in an incorrectly throttled position on the C EDG on August 11, 2006. Both valves were returned to their proper position. Additionally, PSEG increased the amount of SACS flow

available to the EDGs by implementing a temporary modification that throttled a normally full-open valve to the RHR heat exchangers on August 8, 2006. This throttling reduced the amount of excess cooling to the RHR heat exchanger and made more cooling available for the EDGs. The temporary modification was inspected and documented in NRC Integrated Inspection Report 05000354/2006004 in Section 1R23. The temporary modification was made a permanent plant modification during this inspection period.

Analysis:

The inspectors determined that PSEG did not fully identify a condition adverse to quality in a timely manner. Specifically, evaluations that were created to identify deficiencies in the EDG lube oil cooling system in response to inspector questions were deferred several months beyond the seasonal period when the systems would be challenged again by higher ambient air and heat sink temperatures. The finding is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone and affected the cornerstones objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences. In accordance with Inspection Manual Chapter (IMC) 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, the inspectors conducted a Phase 1 SDP screening and determined the issue to be of very low safety significance (Green). The finding was not a design or qualification deficiency, did not represent a loss of system safety function, did not represent an actual loss of safety function of a single train for greater than its Technical Specification Allowed Outage Time, did not represent an actual loss of safety function of one or more non-Technical Specification trains of equipment designated as risk significant per 10 CFR 50.65, for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and did not screen as potentially risk significant due to external events. The finding has a cross-cutting aspect in the area of problem identification and resolution because PSEG did not promptly identify deficiencies that caused higher than expected temperatures in EDG lube oil systems.

Enforcement:

10 CFR 50 Appendix B, Criterion XVI, Corrective Actions, states, in part, that measures shall be established to assure that conditions adverse to quality are promptly identified and corrected. Contrary to the above, PSEG did not promptly identify deficiencies that caused higher than expected temperatures in EDG lube oil systems, which was initially observed during testing on August 8, 2005. This led to the delayed discovery of mispositioned SACS throttle valves on the B EDG that resulted in exceeding the 170 degrees F procedural limit on lube oil temperature during a surveillance test of the B EDG on July 31, 2006.

Because this finding is of very low safety significance and has been entered into the corrective action program in notification 20293067, this violation is being treated as a NCV, consistent with section VI.A of the NRC Enforcement Policy.

.5 Annual Sample: Problems with Moisture Separator and Feedwater Heater Valves

a. Inspection Scope

=

The inspectors reviewed PSEGs actions to resolve problems associated with feedwater heater and moisture separator level control. A number of issues have been identified in

the PSEG corrective action process (CAP) describing degraded conditions relating to level controllers, drain valves and dump valves. The issues were selected for review based on their potential to increase the likelihood of an initiating event, or cause the actuation of a safety system. The inspectors reviewed PSEG procedures, vendor documents, design change packages, notifications, orders, corrective actions, apparent cause investigations, and a root cause analysis to understand the equipment functions and operational history, as well as the identification, evaluation, and corrective actions associated with the degraded conditions. System engineers, design engineers, reactor operators and other PSEG staff were interviewed to supplement the document review process.

The following examples illustrate a sampling of issues associated with feedwater heater and moisture separator level control problems:

In October and November of 2005, PSEG removed the 6A feedwater heater (FWH)from service several times due to higher-than-expected vibrations in the 6A cascading drain piping to the 5A FWH. An apparent cause evaluation of the vibrations revealed flashing in the valve internals of the 6A FWH level control valve (LCV) 1AFLV-1506A due to a higher-than-expected pressure drop within the valve. Corrective actions were implemented to replace 1AFLV-1506A during refueling outage 13 (RF13) with a new LCV designed with staged pressure drops specifically to prevent internal flashing (DCP

===80088090). An extent of condition investigation revealed acceptable vibration levels in the remainder of the heater drain lines. However, additional corrective actions were implemented to replace the 6B and 6C FWH LCVs during the next refueling outage (RF14) in October 2007.

On May 12, 2006, the 5C FWH tripped during preparations to place the C reactor feed pump in service. PSEG personnel tuned the level controllers of several feedwater heaters and subsequently identified a water hammer condition that contributed to the 5C FWH trip. Corrective actions were taken to address this condition.

b. Findings and Observations

No findings of significance were identified.

The inspectors determined that PSEG appropriately identified degraded conditions associated with feedwater heater and moisture separator level control and entered them into the corrective action program. Evaluations of degraded conditions were thorough, and included considerations for extent of condition. The inspectors determined that corrective actions developed by PSEG adequately addressed the identified deficiencies.

4OA3 Event Followup

.1 (Closed) LER 05000354/2006-004-00, Main Steam Line Radiation Monitor Set Points

On August 23, 2006, PSEG identified that all main steam line radiation monitors (MSLRMs) were inoperable. Technical Specification 3.3.2, "Isolation Action Instrumentation," requires that MSLRM isolation trip systems without operable channels be placed in the tripped condition within one hour. PSEG placed the 'A' and 'C' trip systems in a tripped condition, but contrary to the requirement, PSEG did not place the B or D MSLRM trip system in a tripped condition within one hour. The inspectors

reviewed the LER and evaluations associated with the performance deficiency. The enforcement aspects of this finding are discussed in Section 4OA7. This LER is closed.

4OA5 Other Activities

Temporary Instruction 2515/169: Mitigating Systems Performance Index Verification

a. Inspection Scope

=

Temporary Instruction (TI) 2515/169 was issued on July 25, 2006, to verify that licensees have correctly implemented the Mitigating Systems Performance Index (MSPI)guidance for reporting unavailability and unreliability of the monitored safety systems.

The MSPI replaces the four safety system unavailability (SSU) indicators currently in use in the Reactor Oversight Process. The MSPI monitors the unavailability and unreliability of the same four safety systems that comprise the SSU indicators; however, it also monitors the cooling water support systems for those four safety systems. For Hope Creek, the systems monitored by the MSPI are: high pressure coolant injection (HPCI) system, reactor core isolation cooling (RCIC) system, the suppression pool cooling function of the residual heat removal (RHR) system, the emergency diesel generators (EDGs), and the cooling system comprised of the service water (SW) system and safety auxiliaries cooling system (SACS).

The inspectors reviewed the Hope Creek MSPI Bases Document, Nuclear Energy Institute (NEI) 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 4, station procedures, maintenance rule data, notifications, control room operating logs, technical specification log entries, system engineering notebooks, and a compilation of MSPI data to complete the following inspection requirements:

  • On a sampling basis, the inspector will review the licensees list of surveillance activities which, when performed, do not render the train unavailable due to the short duration of the activity (less than 15 minutes).
  • On a sampling basis, the inspector will review the licensees list of surveillance activities which, when performed, do not render the train unavailable due to the credit for operator recovery activities as defined by Nuclear Energy Institute (NEI) 99-02 (Regulatory Assessment Performance Indicator Guideline),

Revision 4, page F-6.

  • For each MSPI system, using the general concepts discussed in Section 1.2.2 of Appendix F of NEI 99-02, Revision 4, the inspector will independently determine the baseline planned unavailability hours and confirm that these hours were correctly translated into the basis document.
  • On a sampling basis for each MSPI system, using operating logs, corrective maintenance records, and condition reports, the inspector will confirm that the actual planned and unplanned unavailability data is accurate.
  • On a sampling basis for each MSPI system, based on a review of related maintenance and test history, the inspector will confirm the accuracy of the failure data (demand failures, run/load failures, and failures to meet the risk-significant mission time, as applicable) for the identified monitored components.

The TI also requires the documentation of the following questions and their answers:

For the sample selected, did the licensee accurately document the baseline planned unavailability hours for the MSPI systems?

For the sample selected, did the licensee accurately document the actual unavailability hours for the MSPI systems?

For the sample selected, did the licensee accurately document the actual unreliability information for each MSPI monitored component?

Did the inspector identify significant errors in the reported data, which resulted in a change to the indicated index color? Describe the actual condition and corrective actions taken by the licensee, including the date when the revised PI information was submitted to the NRC.

Did the inspector identify significant discrepancies in the basis document which resulted in

(1) a change to the system boundary;
(2) an addition of a monitored component; or
(3) a change in the reported index color? Describe the actual condition and corrective actions taken by the licensee, including, the date of when the bases document was revised.

b. Findings and Observations

No findings of significance were identified.

In response to the five questions listed in the Inspection Scope, the inspectors determined that:

PSEG accurately documented the baseline unavailability hours for the MSPI systems.

PSEG accurately documented the actual unavailability hours for the MSPI systems.

PSEG accurately documented the actual unreliability information for each MSPI monitored component.

The inspectors did not identify significant errors in the reported data that resulted in a change to the indicated index color.

The inspectors did not identify significant discrepancies in the basis document which resulted in

(1) a change to the system boundary;
(2) an addition of a monitored component; or
(3) a change in the reported index color.

4OA6 Meetings, Including Exit

On January 5, 2007, the inspectors presented their findings to members of PSEG management led by Mr. G. Barnes. None of the information reviewed by the inspectors was considered proprietary.

4OA7 Licensee-Identified Violations

The following violations of very low significance (Green) were identified by PSEG and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as non-cited violations.

C Technical Specification 3.3.2, "Isolation Action Instrumentation," requires that main steam radiation monitor (MSLRMs) isolation trip systems without operable channels be placed in the tripped condition within one hour. Contrary to this requirement, on August 23, 2006, PSEG identified that all MSLRMs were inoperable but did not place the B or D MSLRM trip system in a tripped condition within one hour. The 'A' and 'C' trip systems were placed in a tripped condition. PSEG entered this issue into their corrective action program as notification 20294984. The issue was determined to be of very low safety significance, based on IMC 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, because it was not an ALARA planning or work controls issue, there was neither substantial potential for nor an actual overexposure, and the ability to assess dose was not compromised.

C 10 CFR 55.46(d)(1) requires, in part, that simulator performance test results be retained for four years or until superceded by updated test results. Contrary to this requirement, the documentation of simulator performance testing, per NRC Regulatory Guide 1.149, Rev. 2 and ANSI/ANS 3.5-1993, consisted of a computer database listing the date of the test and any comments by the tester.

There were no test procedures stating what criteria were used to evaluate these test results for malfunctions, as satisfying the acceptance criteria of the ANSI standard or retention of data for most of the tests conducted. This was identified in PSEGs corrective action program as order 70057878. This issue was of very low safety significance because there was no impact on operator performance and no actual impact to simulator fidelity.
