R0 REPORT No. 50-219/72-04

JERSEY CENTRAL POWER & LIGHT COMPANY

OYSTER CREEK

This inspection was extended to 7 days at the site in an attempt to

close out all of the inquiry reports, Memo route slips from HQ, and

unresolved items from previous inspections. The inspection plan

started with 55 items but was expanded to include additional items

noted or that ocurred during the inspection. A 5 day routine in-

spection had been conducted February - March 1972. The number of

items on the inspection plan as well as the number of inquiry re-

ports for the calendar year to date (28) is an indication of the ac-

tivity associated with BWR's.

Another indication of the activity assoc,iated with reactors is the

~

~

number of different groups that were at the plant during the inspec-

tion. A group from Region I met with HASL, HQ and JCPL one day. There

was a group from Oak Ri-se reviewing the proposed Environmental Report

for two days. EPA and representatives of the State of New Jersey

were taking samples in the discharge canal and in the bay one day.

I was informed by Mr. McCluskey that JCPL planned to create a new po-

sition at Oyster Creek of assistant superintendent. The purpose is to

provide promotional opportunities for present personnel and to provide

better supervision of plant operation.

He indicated that it had become

j

about impossible for one man to follow the operation in the detail

'

needed and to meet the other demand on the station superintendent. He

indicated Don Ross would be promoted to assistant superintendent but would

continue to carry the duties of technical supervisor until a replace-

ment is selected.

(Anticipated date is October 1, 1972 for the replace-

ment).

I concur in the planned action for the same reasons.

The requested action or information was obtained for the following HQ

PORC evaluating the problem

It is our understanding that a proposal has'been made to require all

licensee's to demonstrate the operability of t.he liquid poison sys-

,

(OC's

tem by functionally testing with D.I. water once per cycle.

At OC chis is

TS 4.2 currently require function test cace/ cycle).

the only direct path in which a shattered flow tiwitch could get to

the reactor.

In other systems the poison would ou .:tceped by fil-

ters or demineralizers.

Over a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period the accuracy of the system has been cal-

a.

culated by JCPL to be 1 0.1 gpm at a rate of 1 gpm and 1 0.02

spm at a rate of 5 spm.

A 5 gpm leak would be detected within 20 minutes if the timer

,

J

on the pump works as designed.

(Timer is set to alarm if the

1eakage rate reaches 4 gpm.)

The bases for TS 3.3 states that the " leakage of the magnitude

specified can be detected reasonably in a matter of a few hours

."; " Addition-

utilizing the available leak detector schemes .

al qualitative information is available . . .via the monitored

the latter is almost useless.

The action point administrative 1y for unidentified leakage is

4 gpm to shutdown, however, any increase above the 1-1.2 rpm

normal leakage would require an evaluation. The drywell can-

not be inspected during power operation.

c.

Identified leakage, ie valve and pump packing is piped to one

sump and unidentified leakage goes to another sump. OC has

determined a fan cooler leak by water analysis.

(Fan cooler

leakage is considered unidentified.)

d.

The minimum sensitivity of the leak detection system (based

on the sumps) is given in a. (above).

OC had same problem. Details in report Paragraph 24.

The information or action requested by your notes on memos was ob-

tained as follows:

censee

2/ Note (5/26/72) Shipping Cask Liner Failure-advised licensee

3/IM 3/72-02 Bearing Failure Limitorque Valve

Licensee does not have this model.

Tanks. No floating membranes at OC.

4p----The licensee has been requested to supply us with up-to-date copies

of P&ID in nse at the plant. We provided him a list of the drawings

we have and the list of revisions.

Some revisions have been supplied

in the form of blue print size drawings.

According to the letter which was written approximate 1: 20 days

af ter Jersey became aware of the overexposures, GORB was still

planning to investigate the overexposure.

It is my understanding

that the reason a 30 day report is required (vs a 10 day report)

is;to allow time for an investigation and to provide the above

,

information.

If HQ does not inform JCP&L that the report is un-

acceptable, I feel we should cite JCPL for. inadequate controls

or surveys and require them to provide the above information.

Currently _00 does not have a specific requirement to test the re-

lief valves on the Liquid Poison System. Mr. McCluskey stated

that a definite schedule would be established and implemented, how-

.

ever, I feel this matter should be referred to Licensing for inclu-

sion in the TS 's.

I feel JCPL had shown definite improvement in reporting of unusual

events, however, I still plan to encourage prompter. reports.

In- the area of audits by GORB, I f eel that the audits performed

are not in the depth required to detect problems.

I need to do

"

more in this field.myself to come up with specifics. The audit

reports that I have seen generally indicated compliance with pro-

'

cedures.

It is difficult for me to believe that procedures are

adequate and followed and to have as many unusual events and oc-

currences as OC,

If I don't get satisfied in this area, I plan

'

to request that I be informed when audits are being performed and

i

accompany the auditor.

If it still appears to be a problem, I

think we should attend PORC and GORB meetings on an unannounced

L

basis - at least once per year. With our present inspection pro-

gram, we cannot reasonably assure the safe operation of one of

these plants unless these groups funceton as intended.
