Exit Interview

The inspector

met with the licensee

representatives

denoted in para-

graph

1 at the conclusion of the inspection

on December

7,

1978.

The

scope

and findings of the inspection

were discussed.

During the exit

interview the senior licensee

representative

was informed that one

unresolved

item had been identified during the inspection relating to

the lineup for recirculation of the Boric Acid Storage

Tanks.

Subse-

quent to the inspection

on December

12,

1978,

the inspector

telephoned

the licensee

and informed him that the unresolved

item had been

upgraded

to an item of noncompliance

based

upon discussions

with regional

management.

The licensee

recognized

the problem

and had implemented

temporary corrective action.

(BAST)

Recirculation

During a review of licensee

compliance with Technical Specifications,

on December 5,

1978 the inspector identified an apparent violation of

T.S. 3.6.b.4 involving the

Chemical

and Volume Control System.

The

inspector

determined that the licensee

was routinely isolating the

normal

and emergency

borate

flowpath to the unit 3 reactor

from the

BAST.

This lineup was necessitated

by continuing seat

leakage

through

Emergency

Borate Valve No. 350.

Flow from the running Boric Acid

Transfer

Pump must be isolated

from valve 350 to prevent inadvertent

boration of the Unit 3 during recirculation of the

BAST A.

OP 2601.1

CVCS Boric Acid System Valve Alignment, specifies

a valve lineup which

would have both transfer

pumps

3A and

3B lined up to take

a suction

on

BAST A for Unit 3 through the filter, correspondingly transfer

pumps

4A and

4B are lined up for BAST C for Unit 4 through the Unit 4 filter.

BAST B is specified to remain isolated

from all transfer

pumps

and

receive

continuous recirculation

from the newly installed "mini

recirc" pumps.

The actual valve of alignment of this system varied

significantly from the lineup specified in OP 2601.1.

On December 5,

1978,

the day shift nuclear operator

had isolated

the normal injection

flowpath by closing valves

342 and

341

and leaving the

3B transfer

pump lined up on BAST B. The evening shift nuclear operator

on the

same

date demonstrated

to the inspector

the lineup which he routinely

made during recirculation of the

A BAST.

This lineup involved shifting

the suction

and discharge

of the

3B transfer

pump from BAST B to BAST

A prior to isolating the discharge

of the

3A transfer

pump.

The

latter lineup would insure that the required injection flowpath remained

lined up during recirculation in accordance

with T.S. 3.6.b.4.

The

RII Report Nos. 50-250/78-30

and 50-251/78-30

lineup used

by the day shift nuclear operator

would require nuclear

operator action to restore

the required injection flowpath.

Neither

of these

two lineups

was covered

by an approved plant procedure.

Further discussions

with other nuclear plant supervisors

and nuclear

control center operators

revealed that they were not aware, in all

cases

of the varied lineups which were being used.

The lineup is further complicated

by the fact that the mini-recircula-

tion pumps

have experienced

multiple seal failures

and are therefore

not used to continuously recirculate

the Boron Injection Tank.

The inspector

expressed

his concern that the normal

and emergency

boration flow paths

on Unit 3 have been routinely isolated without

proper administrative control or approved plant procedures.

The

licensee

indicated that isolation of a manual valve in a system required

to be operable

did not, in their previous interpretation of the Technical

Specifications,

make that system or flowpath inoperable, particularly

where operator action from the control

room was necessary

to initiate

emergency

or normal boration.

Based

upon review of this situation

with Regional Office management,

the failure to properly control the

Boric Acid System Valve alignment in accordance

with an approved

procedure

or proper administrative controls

has

been designated

an

infraction (250/78-30-01).

In response

to the concern identified by the inspector,

the licensee

issued

a Special Instruction on December

6,

1978, specifying the

correct Boric Acid System lineup to preclude interruption of one of

the

two required boric acid injection flowpaths.

The flowpath from

the Refueling Water Storage

Tank was not affected by this lineup.

The

licensee

indicated that valve 350 would be repaired during the fo~tB-

coming Unit 3 refueling outage.
