of licensee facilities, tours of the facility, interviews and discussions

with licensee personnel, independent verification of safety system status

and limiting conditions for operations, and by reviewing facility records.

The NRC inspectors, by observation, interview of personnel, and review of

documents, verified the physical security plan was being implemented in

accordance with the security plan and that radiation protection activities

were controlled.

By observing valve position, electrical breaker position, and control

room indication, the NRC inspectors confirmed the operability of the

accumulator safety injection system and the coolant charging system.

4

The NRC inspectors also visually inspected safety components for leakage,

physical damage, and any other impairment that could prevent them from

performing their designed function.

No violations or deviations were identified.

4. Engineered Safety Features (ESF) System Walkdown

!

l

The NRC inspectors verified the operability of ESF systems by walking

down selected accessible portions of the systems. The NRC inspectors

verified valves and electrical circuit breakers were in the required

position, power was available, and valves were locked where required.

The NRC inspectors also inspected system components for damage or other

conditions that could degrade system performance.

The ESF systems listed below were walked down during this inspection

report period:

-

Refueling Water Storage (BN)

-

High Pressure Coolant Injection (EM)

-

Emergency Fuel Oil (JE)

No violations or deviations were identified.

5. Onsite Followup of Events

The NRC inspectors performed onsite followup of nonemergency events that

occurred during this report period. The NRC inspectors (when available)

observed control room personnel response, observed instrumentation

indicators of reactor plant parameters, reviewed logs and computer

printouts, and discussed the event with cognizant personnel. The NRC

inspectors verified the licensee had responded to the event in accordance

with procedures and had notified the NRC and other agencies as required in

a timely fashion.

Engineered Safety Feature actuations that occurred during the report

, period are listed in the table below. Where applicable, the NRC

inspector will review the LER for each of these events and will report

any findings in subsequent NRC inspection reports.

Selected NRC inspector observations:

On March 27, 1986, at 1813 hours0.021 days <br />0.504 hours <br />0.003 weeks <br />6.898465e-4 months <br /> a CRVIS, CPIS, and FBVIS were generated

when the -15 volt DC power supply failed in Cabinet SA 036D. After

approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of reviewing prints, the instrumentation and control

(I&C) personnel trouble shooting the problem removed a fuse in a 120V AC

circuit and when it was replaced, an AFW actuation occurred along with an

AFW low suction pressure automatic switchover to ESW. As designed, only

the '1A' train ESW pump started. The balance of plant (80P) operator

shut down the three running AFW pumps before any ESW water was placed in

the steam generators (S/Gs).

Operations personnel flushed the ESW water out of '1A' motor driven AFW

pump and the turbine driven AFW pumps (TDAFWP) using 1-inch drain lines and

gravity feed from the condensate storage tank (CST). After chemistry

4

samples taken from the AFW system and analyzed indicated the system was

again clean, the AFW pumps were run in their normal modes supplying water

to the S/Gs to ensure all ESW water was flushed from the AFW system.

Currently an evaluation is in progress to determine the corrective action

required to ensure that the' long term operation of the AFW system has not

been degraded through chemical reactions to the ESW water. The NRC

inspector will follow up this evaluation to verify proper corrective

action has been taken. Using Work Request (WR) 01336-86, I&C replaced the

failed power supply on March 28, 1986. This will be tracked as Open Item

No. 50-482/8605-02.

No violations or deviations were identified.

6. Monthly Surveillance Observation

The NRC inspectors observed selected portions of the performance of.

to verify that surveillance activities were performed in accordance with

TS requirements and administrative procedures. The NRC inspectors

considered the following items while inspecting survePlance activities:

- Testing was being accomplished by qualified personnel in accordance

with an approved procedure.

- The surveillance procedure conformed to TS requirements.

- Required test instrumentation was calibrated.

- Technical Specification limiting conditions for operation (LCO) were

satisfied.

- Test data was accurate and complete. Where appropriate, the NRC

inspectors performed independent calculations of selected test data

to verify their accuracy.

-

The performance of the surveillance procedure conformed to applicable

administrative procedures.

-

The surveillance was performed within the required frequency and the

test results met the required limits.

Surveillances witnessed and/or reviewed by the NRC inspectors are listed below:

-

STS IC-920, Revision 4, " Containment Hydrogen Analyzer GS 065A

Calibration Test"

-

STS EJ-100A, Revision 0, "RHR System Inservice Pump '1A' Test"

-

STS GK-001B, Revision 5, " Control Room Emergency Ventilation System"

-

STS IC-913, Revision 4, " Containment Hydrogen Analyzer GS 065B

Calibration Test"

-

STS88-004, Revision 4, "RCS Water Inventory Balance"

Selected NRC inspector observations:

-

On March 26, 1986, the NRC inspector observed a portion of the

performance of STS GK-001B and then reviewed the surveillance proce-

dure. During this review, the NRC inspector observed that even though

the surveillance had been in progress for a number of hours, Section 3,

" Initial Conditions," had not been signed off as completed. When the

supervising operator was informed, he stated, that when the previous

shift had started the surveillance, they had missed signoff of this

section. This failure to document the performance of a Section 3 of

the surveillance in accordance with procedure is an apparent violation

(50-482/8605-01).
