Superintendent, and Mr. D. Reeves, Chief Engineer. Messrs..Sullivan,

j

Swift, Riggle. Growney and Skalsky were also in attendance for JCP&L.

'

Items discussed are summarized below:

A.

General

r

The' inspector summarized the scope of the special inspection, as

restricted to a review of circumstances surrounding the reactor

startup of January 20, 1974, a review of surveillance records

concerning environmental areas and off-site instrumentation, and

.'

scheduled on shift; observations of routine plant operations. Licen-

see representatives were informed that within the scope of the

inspection, no violations or safety items were identified.

B.-

Observations of Plant Operations

,

The inspector stated that in general, plant operations appeared

,

smooth.

Specific comments were as follows:

,

%=

Plant appearance appeared to be. improving and substantial

1.

painting and housekeeping work was noted in progress.

2.

Smoking and cigarette butts required attention. The. inspector.

stated that the 4F panel in the control room was not secured,

-

and cigarette butts were observed near electrical' cables. The

inspector further stated that this was unacceptable.-

,

3.

Required reading files and standing orders should be reviewed,

specifically to remove obsolete material and to clearly define

J

the authority of standing orders in administrative procedures.

A licensee representative concurred with the inspectors state-

ments.

(Report Details, Paragraph 7.b.)

,

10.

Instrument Panel-Problem

The inspector stated-that his review of circumstances surrounding

the instrument panel fire which. occurred January 21, 1974; indicated

a procedural deficiency which required resolution. :The inspector

further steted his understanding based on previous discussions with

cognizant licensee representatives that procedure 103.12 Revision 1

dated 1/15/74 would be revised to clearly describe shift turnover

Operations

On January 20, 1974, the reactor was critical, following a shutdown

which began January 13, 1974.* At 7:28 P.M. a reactor scram

occurred due to high flux from coldwater injection, when the second

stage reheat valve opened.

Feedwater flow was reduced and subse-

again critical at 10:50 P.M., and in the run mode at 10:00 A.M.

January 21, 1974. At approximately 4:00 P.M. January 21st, removal

of leads from the LPRM downscale inhibit circuit caused a flashover

in the rear of Panel 4F and tripped a breaker which caused a loss of

power to the 4F recorders.

Power was reduced to monitor instrumentation

response and the breaker was reset. On January 22, 1974 power was

again redue. d to less than 50% when the torus atmosphere was not

less than Ehk as required by the Technical Specifications, due to

an inadequate N2 supply.*

Reactivity Control and Core Physics

a.

APRM Down Scale Rod Block Inhibit

f

The licensee had disabled the downscale inhibit block leads

previously installed. Lead removal was conducted in accordance

vith a PORC approved procedure charge request dated January 18,

1974.

This change was reviewed by the inspector. The instru-

ment log indicated that on January 21, 1974 while verifying

'

the leads to be removed, the lead on the involved terminal

board lug (Rear 4F panel) was touched and a loose wire strand

contacted ground, which resulted in a trip of the power feed

breaker in instrument panel 4.

(Interrupting power to nuclear

instrumentation recorders.)

Continuity checks and resistance

to ground were performed and the breaker and circuit was re-

energized.

The inspector visually examined the panel and

-

s

.

,

-6-

observed a small amount of charring and burned lead wires.

Discussion with personnel involved indicated that one operator

heard a " cracking noise" and observed a " flash".

Log records

and charts reviewed indicated that recirculation flow was

reduced to observe instrument response. A licensee represen-

a

Ml

tative stated that all instruments functioned normally during

'

the interval of the occurrence. Plant Records indicated no

scram occurred. Discussion indicated that one licensee repre-

sentative at the control panel was unaware that instrumentation

technicians were performing work. This occurrence happened

during a shift change. The inspector discussed requirements

of the Shif t Turnover Procedure with a licensee representative.

Inclusion of briefing concerning definition of maintenance

activities which could affect plant operation was discussed

at the exit interview. Additionally, the licensee issued a

memorandum during the inspection to operations personnel, to

insure shift changes are performed with minimal confusion and

to complete or defer work and surveillance testing until on-

coming shift personnel have assumed responsibilities.

was determined to be noisy during operation. The valve was

repacked and did not appear to open fully during testing. The

valve was being de-energized from the torque switch rather than

from the limit switch. After disassembly, the stem was found

to be bent, and was subsequently straightened and the valve

reassembled and tested on January 20th. According to licensee

representatives, electricians and operators assisted with the

bulk of this work due to the unavailability of sufficient

maintenance personnel,

b.

Second Stage Reheater PRV Control

On January 20, 1974 a reactor scram occurred from IRM High Flux,

when control of the PRV's was switched without balancing the

system at the " manual loading station". With the manual regul-

ator set at zero psig and the automatic signal at 30 psig, and

the transfer to " auto" was made, both PRV's fully open creating

a steam flow transient requiring feedwater addition. Records

indicated that an IRM trip occurred at greater than 120% on

Range 9.

Reactor pressure was about 350 psig and turbine vacuum

was less than 20"Hg at the time of the scram. Discussion with

involved personnel indicated that switching was performed by a

Effluent Temperatures

The: inspector reviewed bridge temperature and discharge canal

g,;

temperature' charts for the period January 18-24, 1974. Tem-

fio

perature fluctuations wera caused during this interval by a

l'IU

reactor scram, a load reduction and pump actions. One unaccount-

able temperature rise on January 19th was observed.

Miscellaneous

j

.

a.

Labor Problem

Discussion with cognizant licensee representatives indicated

that a dispute occurred with respect to maintenance worker. lunch

periods on January'13, 1974.

On this date according to _ licensee

representatives, some personnel left'for an unauthorized lunch

'

.

break.

As a result, on January 18, 1974, following a. meeting

with plant management, 15 maintenance personnel were suspended

for the remainderlof an eight (8) hour shift. Discussion with

t

maintenance foreman and a workman also indicated that no walk-

outs occurred with the exception of the unauthorized lunch break-

on January 13.

b.

Observation of Shift Operations

During the course of the inspection, the inspectors partici-

WWrf -

pated in on-shift coverage and accompanied shift foreman on

tours of the reactor. The following observations,and deficien -

,

cies which required resolution were discussed at the exit interview.

!

(1) Housekeeping

The licensee's program of repainting and cleaning of the

-

facility is continuing and improvements were noted.

Some

areas toured were in disarray and were attributed to the

cleanup in progress. Painting work is being completed by

outside contractor. The inspectors noted that the 4F panel

front cover at the control console had been removed and

observed cigarette " butts" near electrical cables. Licensee

i

representatives were advised that this was unacceptable.

(2) Required Reading Files

Review of control room files indicated that obsolete material

was maintained in addition to current items, i.e. outdated

radio transmitter license. The current-licensee was conspic-

uously posted in the control room. The inspector discussed

review and updating of these files with n' licensee representative.
