The inspector stated that his review 1ndicated a disparity existed

~

between the recirculation loop temperature recorder and multipoint

readings, such that assurance was not provided to adequately demon-

0

strate compliance with the 50 temperature limit upon startup of an

idle loop.

A licensee representative stated that operators would be required to

monitor and record pump starts and further that the multipoint recor-

der would be examined for accuracy of readings during the next outage.

(Details, Paragraph 5.b(2))

E.

Chromate Water Storage

The inspector stated his position that continued storage of chromate

water in outside tank trucks no longer classified as " temporary

storage," and that this was considered an unacceptable arrangement.

Operations

Reactor operations resumed December 20, 1973. On December 22, the

reactor was operating at about 340 MWe at 10:00 A.M.

A power reduction

was initiated to approximately 292 MWe when a temporary change to the

T. S. was issued by DL permitting operation with containment atmos-

phere greater than 5% 02 (torus). A nitrogen supplier arrived

onsite at about 1:45 P.M. and the licensee was in compliance with

Technical Specification 3.5.A 6 by 2:30 P.M.

At the conclusion of

the inspection the reactor was operating at 515 MWe (1600 MWt).

a.

Reactor Coolant Samples

Surveillance results for the period September 1,1973-January 7,

1974 were reviewed. The licensee analyzes samples on a daily'

basis. Records indicated that requirements of T. S. 3.3.E and

,-;j

T. S. 4.3.E were satisfied concerning content of chloride ion

3

and conductivity.

b.

Thermal Transients

(1) lieatup and Cooldown

The inspector audited temperature recorder chart records on

a sampling basis for the period September 1, 1973-January 13,

1974. Records indicated that the average rate of coolant

temperature change did not exceed 100*F in any one hour

interval, the T. S. limit.

(2)

Idle Recirculation Loop Pump Start

The inspector audited recirculation loop temperature recorder

and multipoint recorder chart records on a sampling basis for

the period September 1, 1973-January 13, 1974. Records indi-

cated that the 50* T. S. limit was not exceeded. The inspec-

tor noted that multipoint recorder points were in some

instances printing inaccurate temperature indications, i.e.,

0-98*.

The inspector also noted that in some instances

$iQ

charts were not marked to indicate which pumps had been

started.

(Recirculation Loop Temperature recorder provides

a permanent record of any two (2) pumps.)

The inspector

discussed documentation requirements with respect to the

50* limit with a cognizant licensee representative. The

representative concurred with the inspector's comments and

stated that in the future, pumps when started would be iden-

tified to provide adequate documentation. The apparent

multipoint recorder problem was also discussed at the exit

interview.

t

c.

Reactor Coolant System Leakage

Surveillance records for the period September 1, 1973-January 11,

1973 were reviewed, and indicated that limits of T. S. 3.3(d) were

not exceeded. An increased unidentified leakage rate occurred in

January 1974.* Unidentified leakage in general varied from 1.0-

1

2.7 gpm.

Identified leakage for the period was approximately

4.0 gpm.

The inspector's review of A0 73-27 concerning closed cooling water

yp"jj

system leakage to the discharge via a service water path indicated

that procedural changes had not been made as discussed in a licensee

letter.* The licensee issued a temporary change notice dated

January 25, 1974 specifying sampling requirements. The inspector

also discussed potential for generic indications of salt water cor-

rosion with a cognizant licensee representative.

Momentary Loss of 125 V DC Power

. . .

A review of events as described in A0 73-31 dated December 14, 1973

indicated the power loss was momentary. The inspector also reviewed

JCP&L memorandums dated July 14, 1969 and December 11, 1970 describ-

ing jumpers and their usage. Based on the above, the referenced loss

was caused when a jumper installation was improperly conducted and

without using a formal written procedure (VIOLATION) . The licensee

subsequently developed a procedure for jumper installation and removal

in response to R0 Bulletin No. 73-6.

The inspector discussed the level

of management review required (Shif t Foreman) with cognizant licensee

representatives. With respect to this event, the licensee has

  • *#l

written and PORC had approved a procedure to check for ground on the

Battery "A" Bus or'"B" Bus.

The procedure review did not indicate

any apparent deficiencies.

Containment

MSIV Spool Valve Problems

A review of A0 73-32 and A0 74-09 and discussions with licensee

representatives indicated that insufficient residue was available

for analysis. The licensee initiated a new procedure prior to

returning the plant to operation following the failure January 16,

1974 to insure that'N2 has replaced air on the inner MSIV's. Param-

eters are observed during the daily 5% closure tests, as indicative

of possible problems. For operation, the licensee has established

a 100 psi minimum pressure (compressor) to assure a N2 atmosphere.

Chromate Water Storage

As a result of the recent chromate water spill * the licensee has

increased surveillance to one tour / hour in addition to shift tour

rounds. The acceptability of continuing storage was also dis-

cussed at the exit interview.

b.

Fish Mortalities

The inspector visited a local marina and visually observed fish

mortality signs from the marina dock. According to a marina

'

owner, signs of dead fish appearing at the water 's surface had been

evident for several days. Gull activity was also present. The

inspector cbserved no fish in distress and based on state of

putrefaction, the fish sighted appeared to be the result of a pre-

vious shutdown (January 11-12, 1974).

Numbers were estimated by

the inspector to be approximately 2,000 fish.
