General Status Unit 1 operated at power until July 26, when a turbine trip was initiated by a condenser low vacuum trip.
The unit was placed back on line on July 27, and continued normal power operation throughout the reporting period, with normal scheduled power reductions to clean the condenser water boxes.
6.
Operational Safety Verification The inspector' observed control room operation, reviewed applicable logs and conducted discussions with control room operators during the report period.
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, auxi lia ry and turbine buildings 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.
The inspection included a complete walkdown of the Unit 2 auxiliary feedwater (AFW) system.
No discrepancies in valve position, control switches or circuit breaker positions were found.
No violations or deviations were identified in this area.
7.
Maintenance Observation Station maintenance activities concerning selected safety-related systems and components were observed / reviewed to ascertain that they were conducted in accordance with requirements. The following items were considered during this review; the limiting conditions for operation (LCO) were met, activities were accomplished using approved procedures, functional testing and/or calibrations were performed prior to returning components or systems to service; quality controi records were maintained; activities were properly certified; and radiological controls were implemented as required.
Work requests were reviewed to determine the status of outstanding jobs and to assure that priority is assigned to safety related equipment maintenance which may affect system performance.
l The following maintenance activities were personally observed during the l
inspection period:
l 1.
lA Diesel Generator air compressor out of service. The PWO and parts ordering status were investigated.
2.
Unit 1 condenser tube rupture. Troubleshooting, repairs, and secondary chemistry recovery progress were reviewed.
3.
The ongoing replacement of Unit 2 spent fuel pool storage racks was followed.
..

The following completed plant work orders (PW0s) were reviewed for accuracy and completeness:
PWO - 3443 - 1A Charging pump - change out discharge and suction valves.
PWO - 3444 - IB Charging pump - replace discharge relief valve.
PWO - 3452 - Valve LCV - 2110P - replace seals.
PWO - 3469 - 1A Diesel generator soak-back oil pump replace coupling.
8.
Surveillance Observation During the inspection period, the inspector verified plant operations in compliance with at least sixteen different Technical Specification (TS)
requirements. Typical of these were confirmation of compliance with the TS for reactor coolant chemistry, the refueling water tank, containment pressure, control room ventilation and AC and DC electrical sources.
The inspector verified that testing was performed in accordance with adequate procedures, test instrumentation was calibrated, LCO were met, removal and restoration of the affected components were accomplished, tests results met requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personnel.
9.
I.E. Bulletins a.
(Closed Units 1 and 2) IEB 84-02:
Failures of GE type HFA relays in
.
Class 1E Sa fety Systems.
The inspector reviewed the licensee's completed corrective actions described in response letter L-84-182 dated July 18, 1984. This also completes actions related to previously identified concerns with GE type HFA relays as addressed in IE Information Notices Nos. 81-01 and 82-13.
b.
(Closed, Unit 2) 1EB 83-08:
Electrical Circuit Breakers With an Undervoltage Trip.
Licensee response L-84-166 dated July 2, 1984 provides a description of breakers in use that isolate non-safety related loads from safety related buses on loss of power.
Licensee evaluation determined that design margins were adequate and that the current breaker surveillance program is adequate to assure continued satisfactory operation.
,
10.
Reactor Trip On July 26, 1984, Unit 1 tripped (turbine trip reactor trip). The turbine trip was caused by the condenser low vacuum trip unit.
Initial indications were that a missing nut inside the trip unit may have permitted the trip piston stem to ride up, causing an indicated low vacuum trip.
The missing nut was not located. A new nut was put on the stem with "Locktite", the trip unit was tested several times and the plant was returned to power.

Followup of Previously Identified Items a.
(Closed Unit 2) IFI-389/83-1.1-01 Annunciator response procedure.
Periodic reviews of the Unit 2 annunciator response procedure has indicated that this item can now be closed.
b.
(Closed Unit 1) IFI-335/8tJUS-01 Sequence of events recorder (SER).
Administrative procedure 1-0010125, schedule of periodic tests, checks and calibrations was amended to include a routine shift check that the SER is in the "On-Line" position.
This action provides sufficient control to justify closing the item.
c.
(Closed Unit 2) IF 389/82-63-01 Fire stations inside containment. The inspector confirmed that revision 2 to FSAR Figure 9.2.4 includes the four fire hose stations.
d.
(Closed Unit 2) IFI 389/82-34-01 QA topical report.
The inspector confirmed that Revision 7 of the licensee's QA topical report included reference to Regulatory Guide 1.8 and ANS 3.1-1978.
