Specifically, on October 30, 1994, the plant was shut down and taken to Mode-5 (Cold Shutdown).

This outage exceeded 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and per Technical Specification requirements Engineered Safety Feature slave relay testing was required.To satisfy this requirement OST-1083 and OST-1084 were satisfactorily completed, however the slave relay circuits for the CSIP Alternate Mini-Flow Isolation Valves, 1CS-746 and 1CS-752 were not tested due to an error that occurred during a procedure revision in June 1993.In September 1992, a plant modification was completed on the Charging/Safety Injection Pump (CSIP)Alternate Mini-Flow System that necessitated revisions to Operations Surveillance Test procedures OST-1083 and OST-1084.These revisions were completed in June 1993 and removed the slave relay testing for CSIP Alternate Mini-Flow Isolation Valves (1CS-746 and 1CS-752)from OST-1083 and OST-1084 and transferred the testing requirement to procedure OST-1809.The cause of the Technical Specification violation was personnel error during the June 1993 procedure revision process for OST-1083 and OST-1084.OST-1809 was successfully performed during Refueling Outage 6 on September 8, 1995.This test verified the operability of these circuits, thus no immediate corrective action was required upon identification of the deficiency.

Additional corrective actions included personnel counseling, appropriate procedure revisions and the continuation of an in-progress Technical Specification testing program review.Three additional Technical Specification testing deficiencies (items 6,7,8)were identified during the on-going comprehensive Technical Specification testing program review and are being reported by this supplemental report.

On January 17, 1996, a failure to perform Technical Specification surveillance testing during an October 1994 planned maintenance outage was identified.

The identification of this condition was a result of an on-going comprehensive Technical Specification testing program review that began in September 1995 following submittal of LER 95-07.Specifically, on October 30, 1994, the plant was shut down and taken to Mode-5 (Cold Shutdown)for a planned maintenance outage.This outage exceeded 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and therefore, per Technical Specification 4.3.2.1 requirements, Engineered Safety Feature (ESF)slave relay testing was required for the 13 ESF relays delineated in Table 4.3-2 that had not been tested in the last 92 days due to being at full power operations.

To satisfy this requirement OST-1083 and OST-1084 were completed on November 3, 1994.However, the slave relay circuit~for the CSIP Alternate Mini-Flow Isolation Valves (ICS-746 and 1CS-752, EIIS Code BQ-ISV)were not tested due to an error that occurred during procedure revisions performed in June 1993 on Engineered Safety Feature (ESF)18-Month Slave Relay Operations Surveillance Test procedures OST-1083 and OST-1084.This error involved inappropriately removing the slave relay testing for the 1CS-746 and 1CS-752 circuits from OST-1083 and OST-1084 and transferring the testing requirement to procedure OST-1809 (Refueling Water Storage Tank switchover to the Containment sumps), which is also an 18-month ESF response time test.OST-1809 was not performed following the October maintenance outage, thus resulting in the testing omission and Technical Specification violation.

During the investigation of this event, personnel performing the Technical Specification testing program review verified tha OST-1809 had been successfully performed during Refueling Outage 6 on September 8, 1995, which verified the operability of the affected circuits.The June 1993 revisions to OST-1083 and OST-1084 were performed to incorporate a plant modification (PCR-6547) on the Charging/Safety Injection Pump (CSIP)Alternate Mini-Flow lines.This modification removed the previously installed relief valves and provided an"open" signal to 1CS-746 and ICS-752 upon receipt of a Safety Injection signal.This condition was determined to be a violation of the Technical Specification surveillance test periodicity requirement and is being reported per 10CFR50.73(a)(2)(i)(b).

The following additional Technical Specification testing deficiencies have been identified by the on-going comprehensive Technical Specification testing program review: Slave relays (K635&K640)for the Auxiliary Feedwater (AFW)Flow Control Valves (EIIS BA-FCV)were not tested within their required quarterly surveillance interval following Refueling Outage (RFO)5 in 1994 through RFO 6 in October 1995.This was a result of inadequate technical reviews associated with the plant modification (PCR-6502) that installed the auto-open signal to these valves.PCR-6502 specified the slave relay surveillance testing interval as once per 18 months per Technical Specification 4.7.1.2, but failed to identify the quarterly requirement contained in Technical Specification 4.3.2.1.Both of these relays were subsequently tested following RFO 6, which verified their operability.

This condition was identified on February 1, 1996.Testing for manual Safety Injection (SI, EIIS-BQ)and Containment Spray (CS, EIIS-BE)actuation has not fully tested all switch contacts within the required 18 month surveillance test interval per Technical Specification 4.3.2.1 The Operations Surveillance Test Procedures (OST-1825&OST-1826)that verify the operability of the actuation circuits, only test one of the two manual actuation switches for each signal once per 18 months, thus resulting in the Technical Specification violation.

The alternate test switch has been satisfactorily tested approximately once pe 36 months due to test performance staggering.

Based on this previous testing, the SI and CS switches are currently operable.However, one set of CS switches will become inoperable on March 3, 1996 and one SI switch will become inoperable on March 19, 1996.This condition has existed since initial development of OST-1825&OST-1826 and was identified on February 12, 1996.F RM A (4-5)

Inattention to detail and an incomplete understanding of the Technical Specification testing requirements for the radiation monitor circuitry caused the deficiency.

The testing requirements foi these radiation monitors were removed from Technical Specifications in May 1995, but due to the time frame of the deficiency, the condition constitutes a violation and is therefore included in this LER supplement.

This condition was identified on February 14, 1996.Proper overlap testing has not been performed for an actuation of the Fuel Handling Building Emergency Ventilation System (EIIS-VG)originating from a high radiation alarm signal, as per Technical Specification 4.9.12.OST-1048 tests this feature, but does not include a particular section of cable (b'12913M-SA) between the North Spent Fuel Pool Radiation Monitor (RM-IFR-3567A-SA) and the South Spent Fuel Pool Radiation Monitor (RM-1FR-3564A-SA).

This condition has existed since initial development of OST-1048 and was identified on February 19, 1996.Logic testing for the Control Room Emergency Filtration Fans (R-2"A" and"B")has inadequately verified all automatic fan start signals associated with a Control Room Isolation Actuation.

OST-1825 and 1826 have properly verified that the fans automatically start upon receipt of a safety injection actuation signal, however, the operability of a parallel circuit path that provides an automatic start signal on high radiation has not been verified during past testing.This condition has existed since initial development of the applicable surveillance procedures and constitutes a violation of Technical Specification 4.3.2.1.surveillance requirements.

This condition was identified on February 22, 1996.Logic testing for the Reactor Auxiliary Building Electrical Equipment Protection Room Inlet Isolation Valves (1CZ-7&1CZ-8)has not properly verified the operability of each actuation circuit path.These valves receive a thermal overload bypass signal from two parallel sources;a Control Room Ventilation Isolation Signal and a signal from the Emergency Safeguards Sequencer.

Surveillance testing has properly verified the operability these circuits from the Emergency Safeguards Sequencer.

However, a portion of the thermal overload bypass circuit for Control Room Isolation has not been verified when the signal is generated from high radiation.

This constitutes a violation of Technical Specification 4.3.2.1 surveillance requirements.

This condition has existed since initial surveillance procedure development and was identified on February 26, 1996.Trip Actuating Device Operational Testing has not been adequately performed for the Main Feedwater Pump trip signal following a safety injection actuation.

OST-1825 actuates the safety injection switch and then verifies that the Main Feedwater Pumps trip, but due to the process involved during this testing, which includes lifting several leads and installing jumpers in Auxiliary Relay Panel (ARP-10), a section of internal wiring in ARP-10 has not been verified.This testing deficiency has existed since initial surveillance procedure development and constitutes a violation of Technical Specification 4.3.2.1 surveillance requirements.

This condition was identified on March 4, 1996.N RM

Item 1: The failure to adequately test the K635 and K640 slave relays for the AFW Flow Control Valves was caused by inadequate technical reviews associated with plant modification PCR-6502.This resulted in deficient surveillance test procedures developed to verify the operability of the automatic open signal for the flow control valves on a quarterly basis.Items 2 3 4 5: Each of these items were caused by inadequate surveillance test procedures that resulted from incorrectly interpreting how to implement Technical Specification testing requirements.

The test procedures for the Safety Injection and Containment Spray manual actuation switches, as well as the FHB Emergency Ventilation system, were based upon this incorrect interpretation and have been deficient since initial development.

The radiation monitor MST revisions completed in 1993, were intentionally performed to eliminate what was considered to be redundant and unnecessary testing steps.This decision was also based on the incorrect testing requirement interpretation, as was the revision to OST-1086 that resulted in the acceptance criteria section not listing 1CS-196, and subsequently resulting in the failure to test the valve.trams 6 7 8 Each of the three additional items reported in this supplement were identified as a result of the on-going Technical Specification testing program review and were caused by inadequate surveillance test procedures that resulted from incorrectly interpreting how to implement Technical Specification testing requirements.

SAFETY SIGNIFICANCE:

There were no adverse safety consequences as a result of this event.The CSIP Alternate Mini-Flow Isolation Valve circuits were tested satisfactorily on September 8, 1995 to verify operability.

This testing provides confidence that had an accident occurred requiring CSIP mini-flow protection due to the re-pressurization of the Reactor Coolant System during a safety injection, the isolation valves would have opened to prevent pump damage.There were no adverse safety consequences as a result of the additional items reported in this supplement.

In each case where applicable, subsequent testing was performed that verified the operability of the effected component or circuit.PREVIOUS SIMILAR EVENTS: Previous events have been submitted as LERs related to surveillance testing deficiencies caused by procedural inadequacies.

LER 95-07, which was submitted on September 28, 1995, contained a corrective action to perform a comprehensive Technical Specification testing program review and it was during this review process that the CSIP Alternate Mini-Flow Isolation Valve condition was identified.

This review is being performed by a multi-discipline team and is still in progress.The Three additional items reported in this supplement were identified as a result of the on-going Technical Specification testing program review.ORM 3 A (4-9 NRC FORM 3BBA I4-BBI LICENSEE EVENT REPORT (LER)TEXT CONTINUATION US.NUCLEAR REGULATORY COMMISSION FACILITY NAME nI Shearon Harris Nuclear Plant~Unit 41 TEXT rif mort sport is nrrvitrE vst trfdrrdrotl sopits of HRC Form 3SQI II 7)OOCRET 50400 LER NUMBER IB)YEAR SEOUENTIAL REVISION NUMBER NUMBER 66-002-02 PAGE I3)5 OF 6 CORRECTIVE ACTIONS COMPLETED:

Item¹1 OST-1044 was revised in December 1995 and OST-1045 was revised in February 1996.These revisions incorporated K635 and K640 slave relay testing on a quarterly basis.Item 2: To address the SI switch that becomes inoperable on March 16, 1996, a Request for Exigent License Amendment was submitted to the NRC on February 16, 1996.This requests a one-time extension of the testing interval for testing the SI switch, due to the hazards involved with testing while on-line.Operations Surveillance Test procedure (OST-9016T) will be revised and performed to test the CS switches prior to their surveillance interval expiration date of March 3, 1996.Additionally, a new OST will be developed to properly test each Safety Injection and Containment Spray manual actuation switch once every 18 months.Item 3: OST-1086 will be revised to enhance the acceptance criteria to ensure that testing of the"B" CSIP Normal Mini-Flow Isolation (1CS-196)is included.Item 4: The radiation monitor operability and testing requirements were moved from Technical Specification 4.3.3.10 to the Off-Site Dose Calculation Manual (ODCM)in May 1995.Upon identification of this condition, the effected radiation monitors were declared inoperable.

Appropriate MST procedure revisions were completed and the tests performed, to fully verify the automatic pathway isolation function of the radiation monitors.Additional procedure changes and/or ODCM revisions will be completed to clarify the testing requirements and enhance the performance of future testing.These actions will be completed as addressed in the Harris Plant response to NRC Generic Letter 96-01.Item 5: OST-1048 will be revised to test the FHB Train A Emergency Ventilation actuation from Radiation Monitor RM-1FR-3567A-SA, which will properly include the previously omitted cable.This revision will be completed as addressed in the Harris Plant response to NRC Generic Letter 96-01.F RM 3 A (4-95)
