7. Operational Safety Verification (71707)

The inspectors observed control room operations, reviewed. applicable logs

and conducted discussions with control room operators during the report

period. The inspectors verified the 'perability of selected emergency

systems, reviewed tagout records, and verified proper return to service of

affected components. Tours of the auxilict, building, diesel building,

turtine building and service water structure were conducted' to observe  ?

plant equipment conditions, including fluid leaks and excessive vibra-

tions. The inspector verified compliance with selected Limiting Conditions l

for Operations (LCO) and results of selected.surve'ilance tests. The l

verifications were accomplished by direct observa son of monitoring ]

instrumentation, valve positions, switch positions, accessible hydraulic

'

snubbers, and review of completed logs, records, and chemistry results. j

The licensee's compliance with LC0 action statements were reviewed as l

!

events occurred.

The inspectors routinely attended meetings with certain licensee manage-

ment and observed various shift turnovers between shift supervisor, shift

foremen and licensed operators. These meetings and discussions provided a

daily status of plant operations, maintenance, and testing activities in

progress, as well as discussions of significant problems. l

The inspector verified by observation and interviews with security force

members that measures taken to assure the physical protection of the

facility met current requirements. Areas inspected included the organiza-

tion of the security force; the establishment and maintenance of gates,

doors, and isolation zones; that access control and badging were proper;

and procedures were followed.

On April 27, 1987 at approximately 7:30 a.m., the operator at-the-controls

(0ATC) reactor operator position on Unit 1 control board was left

unattended for approximately 20 seconds. Even though the position was not

properly attended by the plant operator the shift supervisor, whose desk

is within the designated 0ATC boundries, took over the 0ATC operator

functions when it was noted that he was not within his designate area.

This event was caused by a breakdown in communications. The 0ATC operator

needed to replace a chart recorder with new chart paper. The chart paper

storage is behind the emergency power panel but still inside the main

control room, The unit operator was preparing to

test procedure (STP) at the balance-of-plant (80P) perform

control a surveillance

board which is

behind the main control board. The 0ATC told the unit operator he would

be right back. Apparently the unit operator did not hear this. Both

operators turned away from each other and proceeded out of the 0ATC area.

The 0ATC violated section 3.1.13.5 of Administrative Procedure 16 " Conduct

of Operations, Operations Group" which require that the 0ATC shall under

no circumstances leave the at-the-controls area without obtaining a

qualified relief operator. The shift supervisor was pressed into service

as the 0ATC operator without proper notification and briefing as required

by plant procedures. This is a violation 50-348/87-10-01. The license'e

initiated immediate corrective action which required that all plant

operators read the applicable sections of AP 16. The duties of the

control room operators have been redefined as well as the boundaries of

the 0ATC operator. Training was held for all licensed shift personnel and

was documented by training attendance sheets.

No other violations or deviations were identified.

8. Licensee Event Reports

The following Licensee Event Reports (LERs) were reviewed for potential

generic problems to determine trends, to determine whether information

included in the report meets the NRC reporting requirements and to s

consider whether the corrective action discussed in the report appears 1

appropriate. Licensee action, with respect to selected reports, were J

reviewed to verify that the event had been reviewed and evaluated by the

licensee as required by the Technical Specification; that corrective  !

action was taken by the licensee; and that safety limits, limiting safety j

setting and LCOs were not exceeded. The inspector examined selected i

incident reports, logs and records, and interviewed selected personnel, j

The following reports are considered closed:  ;

i

Unit 1 LERs

LER 87-06 - Personnel error results in missed fire watch. This l

'

licemee identified violation meets the requirements of

I

10 CFR Part 2, Appendix C, Section V and therefore, this

violation is not cited.  !

l

LER 87-07 - Reactor trip due to source range detector failing high

No violations or deviations wert identified.

9. Follow up of Plant Events (93702)

On May 14,1986 at 10:45 a.m. Unit 1 tripped from 100% power from steam l

flow greater than feed flow coincident with low steam generator level in  !

10 steam generator. The engineered safeguards systems were not I

challenged. The i, rip occurred as a result of operator error. The I

operator was running two diesel generators. While preparing to remove one l

of the diesel generators from service he inadvertently opened the wrong

electrical breaker. The breaker which was opened fed 4160V buss 1H. This

buss did not auto fast transfer to its alternate feeder. This denergized

Reactor Coolant Pump 1C as well as motor control centers (MCC). The MCC's

which supply power to the hydraulic oil pumps on 1A and IB steam generator

turbine feed pumps lost power which caused the main feed pump turbines to

trip. The licensee is investigating the auto fast transfer on 1H buss.

The inspector had no further questions.

No violations or deviations were identified.

10. Service Water Modification to 1B RHR Room Cooler.

The licensee completed the change out of two-inch and under carbon steel

pipi'1g to stainless steel piping on the service water cooling to 1B RHR

pump room cooler. The work was completed under PCN 584-1-2914 and

controlled under MWR 157474 and MWR 138205,

It should be noted that gaseous releases from the plant have decreased

from 1984 values. Also, reported quantities of gaseous fission and

activation prooucts and iodines were less than the 1985 averages of

gaseous releases per unit for 21 operating PWRs in Region II (5180 curies

and 0.06 curies respectively). Liquid releases of fission and activation

products did not vary significantly from the 1984 values but were below

the 1985 average liquid release per unit of 1.35 curies. However, liquid 4

tritium releases were approximately 1.5 times the 1C'35 average of

420 curies per unit. No uncontrolled releases of either liquid or gaseous

effluents were reported for calendar year 1986.

Technical Specification 6.9.1.8 requires the radioactive effluent release i

report to be submitted 60 days after January 1 of each year and to include  !

an assessment of radiation doses to the likely most exposed member of the j

public from reactor releases during the previous 12 consncutive months, i

The assessment of the radiation doses is to ba performed in accordance I

!

with the Offsite Dose Calculation Manual (0DCM). A summary of the 1984,

1985 snd 1986 annual doses to the likely most exposed number of the public  !
