Operational Safety Verification
,
'
'
a.
Control Room Observations
,
J Daily, the inspectors verified selected plant parameters and equipment availability to ensure compliance with limiting conditions for operation of the plant Technical Specifications. Selected lit annunciators were discussed with control room operators to verify that the reasons for them were understood and corrective action, if required, was being taken. The inspector observed shift turnovers biweekly to ensure proper control room and shift manning. The inspectors directly observed the operations listed below to ensure
'
adherence to approved procedures:
Routine Power Operation
--
Reactor Startup
--
Issuance of RWP's and Work Request / Event / Deficiency foms l
--
'
No violati,ns were observed, b..
Shift Logs and Operating Records t
Selected shift' logs and operating records were reviewed to obtain
'
!
infomation on plant problems and operations, detect changes and trends in perfomance, detect possible conflicts with Technical Specifications or regulatory requirements, detemine that records are being maintained and reviewed as required, and assess the effectiveness of the connunicaticies provided by the logs.
No violations were observed.
,
/c.
Plant Tours
'
During the inspection period, the inspectors made observations and conducted tours of the plant. During the plant tours, the inspectors
,
conducted a visual inspection of selected piping between containment and the isolation valves for leakage or leakage paths. This included verification that manual valves were shut, capped and locked when required and that motor operated or air operated valves were not mechanically blocked. The inspectors also checked fire protection, housekeeping / cleanliness, radiation protection, and physical security conditions to ensure compliance with plant procedures and regulatory
,
reqtd rements.
No violations were observed.
d.

--
PTR 821073 on "A" Emergency Service Water System
--
During the verification of PTR 820964, the inspector noted that the position indicators for tagged manual valves SGT 3A and 3B indicated the valves were open when required to be shut. The operators involved in hanging the tags stated that they had used direction of movement of the valve handwheels as verification the valves were shut, not the position indicators, and that they had not changed the position of the valves. Since these valves are reqJired to be open during nomal operation, the licensee reviewed the valve installation and detennined that the valve operators were reverse acting, such that the handwheel is turned in the counterclockwise direction to shut the valve, and that the position indicators for the valves were in fact correct. The licensee shut valves SGT 3A and 3B prior to allowing work to commence on the Standby Gas Treatment system.
In addition, the licensee made an entry in the Operations Department Night Orders to infom all operators of the correct operation of these valves.
e.
Radioactive Waste Systems Controls The inspector witnessed selected portions of a liquid radioactive release to verify that the required release approvals were obtained,
'
the required samples were taken and analyzed, the radioactive waste system was operated in accordance with approved procedures, and the release ~ control instrumentation was operable and in use.
The inspector observed the release of Batch 4596, B Laundry Drain Tank, on October 25, 1982.
The inspector: observed the surveys of radioactive waste shipment number 10-82-064L on October 6,1982, and shipment number WASH 82-55 on October 12,1982. The inspectors also reviewed the shipment records and observed that the shipments were properly labelled.
No violations were observed.

f.
Emergency System Operability The inspectors verified operability of the following systems by ensuring that each accessible valve in the primary flow path was in the correct position, by confiming that power supplies and breakers were properly aligned for components that must activate upon an initiation signal, and by visual inspection of the major components for leakage and other conditions which might prevent fulfillment of their functional requirements.
--
Reactor Core Isolation Cooling
--
Low Pressure Coolant Injection.
--
The inspectors also verified the operability of the following system by performing a complete walkdown of the accessible portions of the system. During the system verification, the inspectors-confimed that the licensee's system lineup procedures matched plant drawings and the as-built configuration; verified that valves were in the proper position, had power available and were locked (sealed) as required; verified that system instrumentation was properly valved in; and verified that there are no obvious deficiencies which might degrade system perfomance such as inoperable hangers or supports.
--
No violations were observed.

F-ST-2R, RHR Service Water Pump and MOV Operability Test, Revision 6,
--
dated May 19, 1982, performed on October 26, 1982.
The inspector also witnessed all aspects of the following surveillance test to verify that the surveillance procedure conformed to technical specification requirements and had been properly approved, limiting conditions for operation for removing equipment from service were met, testing was perfomed by qualified personnel, test results met technical specification requirements, the surveillance test documentation was reviewed and equipment was properly restored to service following the test.
F-ST-2A, RHR Pump Flow Rate Test, Revision 8, dated May 19, 1982,
--
perfomed on October 26, 1982.
During the perfomance of F-ST-24D, Reactor Core Isolation Cooling (RCIC)
Subsystem Automatic Isolation Logic System Functional Test, the inspector noted that for step VII.C.2, which tests the automatic switchover of the RCIC pump suction from the Condensate Storage Tank (CST) to the Suppression Pool on low CST level, the technician did not simulate the icw CST level at level switches 13-LS-76A and 13-LS-77B as required.
Instead, he had lifted the leads at terminals BB66 and BB68 in panel 9-30 which de-energized primary relays 13-AK-60,13-AK-61,13-AK-62 and 13-AK-63, the same relays controlled by the CST level switches. When the inspector questioned this, the technician and shift supervisor stated that this was considered acceptable since the logic system functional test verifies the proper logic and system response once the primary relays de-energize and since the circuit from the sensors (level switches) to the primary relays is checked monthly during the
!
instrument functional test. Upon completion of the surveillance test, the
inspector reviewed the completed data sheet and noted that step VII.C.2 5:as l
signed off as having simulated the CST low level at level switches 13-LS-/6A l
and 13-LS-778. The inspector informed the licensee that the completed data i
sheet did not reflect what was actually done and that no administrative controls were used during the testing to ensure the proper lifting and restoration of leads.
In addition, the inspector pointed out that section 1.F.6 of the Technical Specifications defines a logic system functional test as a test of relays and contacts of a logic circuit from sensor to activated device. The inspector infomed the licenses that failure to perform F-ST-24D as written is a violation of Technical Specification 6.8.

The inspector reviewed the licensee's system for calibration of components associated with safety-related systems or functions but not l
specified in the Technical Specifications as requiring calibration to l
detemine if a backlog of past due calibrations is developing.
In addition, the inspector selected ten installed components, listed below, used to make Technical Specification related measurements or used by a
!
,
-- -.
.
operator during nomal operations or post-accident to verify that they are included in the licensee's system and that reviewed and approved procedures are available to calibrate the component.
Components associated with safety-related systems or functions selected for review included: Jet Pump Loop A Flow 02-3-FI-92A, Standby Gas Treatment System Flow Indication 01-125-FI-100, Reactor Vessel metal temperature 02-3-TR-90, Residual Heat Removal Loop "A" Flow 10-FI-133A, Standby Liquid Control Pump Discharge Pressure 11-PI-65, "A" Core Spray Pump Discharge Pressure 14-PI-48A, High Pressure Coolant Injection Flow Indication 23-FI-108-1,

No violations were observed.
8.
Review of Plant Operations Review and Audit On October 12 and 13, 1982, the inspectors attended Plant Operating Review Comittee (PORC) meetings 82-83 and 82-84. The inspectors verified that the Technical Specification membership and frequency requirements were met. The inspectors also reviewed the minutes from these PORC meetings and detemined that they accurately reflected the decisions and recommendations made by the PORC members in the meeting.
No violations were observed.
9.
Followup on a Plant Trip At 11:43 a.m. on October 7,1982, the reactor scramed from full power on high neutron flux as the result of a reactor pressure spike. The pressure spike occurred when the "D" steam line inboard Main Steam Isolation Valve (MSIV) main disc separated from the valve stem and blocked flow in the "D" steam line. Recent mechanical failures of these Rockwell-Edward Flite Flow Stop Valve MSIV's were the subject of IE Infomation Notice No. 81-28. All systems functioned properly and therewas no Emergency Core Cooling System Actuation following the scram. There was no release associated with this trip.
Upon disassembling the "D" steam line inboard MSIV, the licensee found that the stem disc antirotation pin had sheared. This allowed the stem disc to rotate and unscrew itself from the valve stem. This failure of the stem-to-stem disc threaded connection also causes the main disc to be separated from the valve stem since the main disc is supported and attached to the valve stem by the stem disc. The licensee replaced the stem and stem disc on the "D" steam line inboard MSIV and to prevent recurrence, installed two antirotation pins 900 apart in the stem disc. The licensee also disassembled the "D" steam line outboard MSIV and replaced its stem and stem disc. As with the inboard MSIV, two antirotation pins were installed in the outboard MSIV stem disc. Both the inboard and outboard "D" steam line MSIV's successfully passed a Type C leak rate test following the repairs.

The categories of themodynamics, heat transfer and fluids, and recognizing and mitigating consequences of severe core damage consist of approximately 57 hours6.597222e-4 days <br />0.0158 hours <br />9.424603e-5 weeks <br />2.16885e-5 months <br /> of classroom work and appear to contain all the training required by NUREG-0737.
In addition, related subjectgportions of which deal directly with mitigating core damage are taught. These subjects include features of facility design, instrumentation and control, general and specific operating characteristics, safety and emergency systems, emergency procedures, and emergency operating procedure walkthroughs. No specific number of hours can be assigned to the related subjects which are devoted to mitigating core damage. However, the total retraining associated with this subject is in excess of the 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> which is considered adequate for mitigating core damage training.
All personnel in the operating chain and shift technical advisors have i
l received the training for mitigating core damage through their participation in the retraining program with the exception of the Resident Manager.
A discussion with the Resident Manager, and a review of documentation, shows that the Resident Manager received equivalent training while participating in a 12 week General Electric SR0 Certification course.
In addition, the Resident Manager passed the Facility Training Program examination related to mitigating core damage after completing a Self Study Program.
To ensure that replacement personnel in non-licensed positions in the operating chain receive the required mitigating core damage training, the licensee has included the required training in procedure RPT-ll, Training for Professional and Supervisory Personnel.
While reviewing lesson plans and records relating to NUREG-0737 Retraining Requirements, in the areas of heat transfer, fluid flow, themodynamics, and mitigating core damage, certain matters which require further evaluation were identified. These included: available records make it difficult to detennine that all required training is given to each person required to be i

trained, there appear to be deviations from facility administrative training procedure requirements, individuals training records appear to contain errors,
,
some program requirements to be conducted on a two year cycle are repeated at the end of one year, and approximately 14% of alloted training time is devoted to self study. The licensec stated that a detailed audit of the training program would be conducted by November 30, 1982 to evaluate these preliminary findings. This item is unresolved.

No violations were observed.
11. Followup on Safety Relief Valve Problems During the October 7 to 17, 1982 cutage, the licensee repaired the inoperable themocouple on D Safety Relief Valve (SRV). Following the reactor startup on October 17, 1982, the licensee noted that the tailpiece temperature of the D SRV increased to approximately 3000F, indicating pilot valve seat leakage.
This situation is similar to one on the F SRV prior to the shutdown which was reviewed in Inspection Report 82-15 and for which the licensee declared the F SRV inoperable. The licensee replaced the topworks of the F SRV during the October outage. Since little or no industry data exists to actually correlate relief valve operability with pilot valve seat leakage, the licensee has not declared the D SRV inoperable. The licensee has, however, submitted a proposed change to the Technical Specifications (TS) to establish requirements for operation with SRV tailpiece temperatures greater than 2500F or more than
40 F above the steady state value. This proposed change is similar to TS Amendment 70 issued for the high tailpiece temperature on F SRV prior to the October outage and includes the requirements for reporting, perfoming an
engineering evaluation to justify continued operation and testing the valve in the as-found condition during the next cold shutdown of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or more.
Continued operation with the high tailpiece temperature on D SRV is considered unresolved pending approval of this change to the Technical Specifications.
