Gentlemen:

SUBJECT:

EMERGENCY OPERATING PROCEDURES

INSPECTION AT DIABLO CANYON

UNITS 1 AND 2

This letter

forwards the results

and conclusions of a special

team inspection

conducted

by NRC Region

Y and the Office of Nuclear Reactor Regulation of

activities authorized by NRC Operating License

Nos.

DPR-80 and DPR-82 for

Diablo Canyon Units 1 and 2.

This inspection

was conducted

on November 27,

1989 through December 8, 1989.

At the conclusion of the inspection,

the

findings were discussed

with Mr. Townsend

and other members of your staff

identified in the enclosed

inspection report.

The purpose of this inspection

was to verify that your Emergency Operating

Procedures

(EOPs) are technically correct; that their specified actions

can be

accomplished

using existing equipment,

controls,

and instrumentation;

and that

the available procedures

provide the operator with an effective tool to

manage

and mitigate potential accidents.

The areas

examined during the

inspection are identified in the attached

inspection report.

The inspection

consisted of a selective

examination of procedures,

simulated

emergencies

exercised

on your plant specific simulator, procedure

walk-throughs in the

plant with operations

personnel,

and interviews with a broad selection of your

operations,

procedure writing, and training staffs.

Through direct observation of the performance of selected

procedures

during

the simulator exercises,

and through plant walk-throughs of selected

procedures,

we have concluded that your operating staff can effectively use

the

EOPs to manage

and mitigate serious

operational

events

and that the

EOPs

are technically correct.

However, the inspection did identify numerous

minor deficiencies

in the

EOPs

and areas

where the verification and validation of the

EOPs

was not complete.

These specific items're 'described 'in the enclosed

inspection report for your

staff to review and correct.

These

items are based

on a relatively small

sample of your EOPs.

Consequently

we expect that your staff will expand

upon

this list both qualitatively and quantitatively.

General

areas that need to

be specifically addressed

include improving the verification and validation

program, modifying the writer's guide to make it more definitive, and

improving plant lighting.

Also, during examination of the Operations Traininq Program related to the

EOPs, it was observed that during the requalificat>on cycle your operators

only received

a few hours of simulator training on the Functional Restoration

Procedures

and Emergency Contingency Actions.

Based

on this small amount of

training, the results of the simulator exercises,

and the

EOP walk-throughs

we

believe it is appropriate for your training staff to review the simulator

training progr'am emphasis

to ensure appropriate additional weight is given to

the Functional

Restoration

Procedures

and Emergency Contingency Actions.

Regarding guality Assurance activities related to EOPs, it was determined that

since early 1989 the Action Requests

(AR) initiated by all plant personnel

on

the

EOPs

had been given a blanket deferral to allow for one major change to

the

EOPs.

This practice should not set

a precedent

and

ARs need to be handled

more promptly in the future.

This blanket deferral

reduces

the effectiveness

of the gA program.

In accordance

with 10 CFR 2.790(a),

a copy of this letter and the enclosures

will be placed in the

NRC Public Document

Room.

The response

requested

by this letter and its enclosures

are not subject to

the clearance

procedures

of the Office of Management

and Budget as required

by

the Paperwork Reduction Act of 1980,

Pub.

L.

No.96-511.

Should you have any questions

concerning this inspection,

we will be pleased

to discuss

them with you.

Sincerely,

ennis
