Followup on Open Inspection Items (Closed) Unresolved Item (409/81-21-01)*: Automatic Spray Valve for Main Transformer Area Not in Automatic.
The inspector reviewed the schedule for the completion of the automatic spray system for the main transformer, contained in the February 13, 1981, letter from Crutchfield to Linder. The schedule called for the automatic system to be activated prior to November 1, 1981. This auto-matic activation of the system was verified complete prior to November 1, 1981.
(Closed) Unresolved Item (409/81-21-06)1: THI Item II.K.3.19, Interlock on Recirculation Pump Loops.
The licensee's position, * hat plant modification was not necessary, was accepted by NRR and documented in the August 17, 1982, letter from Crutchfield to Linder.
(Closed) Unresolved Item (409/81-21-08)1: Reactor Scram of November 12, 1981, resulted in an Operational Event similar to that described in TMI Item II.K.3.19 This event was considered by NRR in their evaluation of the licensee's response to TMI Item II.K.3.19 and determined to be acceptable and did not require plant modification. This position is documented in the August 17, 1982, letter Crutchfield to Linder.

(Closed) Open Item (409/82-07-03)8: Fire rating of bullet resistant firedoors. The licensee presented letters dated August 6 and 16, 1982, from Factory Mutual Engineering that indicated the modification that was made to the fire doors for security purpose did not reduce the fire rating of the door.
No items of noncompliance or deviations were noted.
3.
Operational Safety Verification The inspector observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the months of July and August 1982. The inspector verified the operability of selected emergency systems, reviewed tagout records and verified proper return to service of affected components. Tours of the reactor building and turbine building were conducted to observe plant equipment conditions, including potential fire hazards, fluid leaks, and excessive vibrations and to verify that maintenance requests had been initiated for equipment in need of maintenance. The inspector by observation and direct interview verified that the physical security plan was being implemented in accordance with the station security plan.
The inspector observed plant housekeeping / cleanliness conditions and verified implementation of radiation protection controls. During the months of July and August 1982, the inspector walked down the accessible portions of the Reactor Feed, Boron Injection and High Pressure Core Spray systems to verify operability. The inspector also witnessed por-tions of the radicactive waste system controls associated with radwaste shipments and barreling.
These reviews and observations were conducted to verify that facility operations were in conformance with the requirements established under technical specifications, 10 CFR, and administrative procedures.
The inspector reviewed the August 18, 1982 event of thermal stratifica-tion in the reactor vessel to determine if the licensee corrective actions were complete and effective to prevent recurrences. The thermal stratification was caused by the securing of the decay heat removal system for repairs while utilizing the normal reactor coolant
,
purification system to remove decay. heat. The flow path that was l
established with the purification system created a "Short Circuit" which l
allowed water to be removed from the bottom of the Reactor Vessel, cooled, l
then returned back to the bottom of the vessel. This "Short Circuit"
'
allowed the water near the top of the Reactor Vessel to approach 212*F
while the water in the bottom of the vessel remained at approximately
76*F.
The licensr,1 has initiated a change to procedure ACP 7.4 Log Sheet L71 to require that the Reactor Vessel Shell Temperature recorder remain operating and be monitored at all times.
If this monitor had l
been operating, the licenree would have had earlier indication of the thermal stratification tnat was occurring in the Reactor Vessel. The licensee is also reassessing it's initial position to I/E Circular 81-11

which addressed adverse effects of inadequate decay beat removal during shutdown.
, No items of noncompliance or deviations were noted.
4.
Monthly Maintenance Observation Station maintenance activities of safety related systems and components listed below were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with technical specifications.
The following items were considered during this review:
the limiting conditions for operation were met while components or systems were re-moved from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as applicable; functional testing and/or calibrations were performed prior to returning components or systems to service; quality control records were maintained; activities were accomplished by qualified per-sonnel; parts and materials used were properly certified; radiological controls were implemented; and, fire prevention controls were implemented.
Work requests were reviewed to determine status of outstanding jobs and to assure that priority is assigned to safety related equipment maintenance which may affect system performance.
j The following maintenance activities were observed / reviewed:
a.
Installation of Post-Accident Sampling system (MR 0539, 0540 and 0576)
b.
Installation of new fire hose cabinets in turbine building (MR 0268)
c.
Installation of flow indicator in the High Pressure Core Spray
,
j system (FC 53-82-3)
l
!
Following completion of maintenance on the High Pressure Core Spray system, the inspector verified that this system had been returned to service properly.
!
No items of noncompliance or deviations were noted.
i S.
Monthly Surveillance Observation The inspector observed the following Technical Specifications required
-
I surveillance testing and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for operation were met, that removal and restoration of the affected components were accomplished, that test results conformed with technical specifications and procedure requirements and were re-viewed by personnel other than the individual directing the test, and I
