Docket No. 50-220

Gentlemen:

Subject:

Inspection

Report

Number 50-220/86-07

This refers to the modification outage

inspection

conducted

by Mr. C. Anderson

of this office on June 2-13,

1986 of activities authorized

by

NRC License

Number DPR-63 at the Nine Mile Point Nuclear Station Unit Number 1, Scriba,

New York and at the corporate offices, Syracuse,

New York and to the

discussions

of our findings held by Mr. Anderson with members of your staff on

June

6 and June

13,

1986.

The primary purpose of this inspection

was to review Niagara

Mohawk control of

modification activities during the

1986 refueling outage.

Areas

examined during

this inspection

are described

in the

NRC Region I Inspection

Report which is

enclosed with this letter.

The major functional areas

reviewed included:

Design

Control, Installation,

Post Modification Testing

and System Restoration.

Generally,

the inspection consisted of selective

examinations of procedures

and represen-

tative records',

interviews with personnel,

and observations

by the inspectors.

The team observed that

a number of changes

related to the control of modifications

were implemented during the

1986 refueling outage.

These

included the development

of new procedures

and

an increase

in the size of groups responsible

for overseeing

the modifications.

The team concluded that these initiatives provided

a good

mechanism to control modification activities.

However, this inspection identified

several deficiencies.

Four violations were identified and are discussed

in

Appendix A.

In addition, the team inspection findings have

been characterized

as program strengths

or weaknesses,

as appropriate,

and are documented

in

Appendices

B and

C, respectively,

to this letter.

You are required to respond to Appendix A within thirty days of the receipt of

this letter, stating actions

taken or planned to correct the violations.

We

also request that you describe

any proposed

changes

to improve the areas

iden-

tified as weaknesses

in Appendix

C.

We are particularly concerned

about the apparent

inadequacies

in your contractor

quality control activities as evidenced

by the violations found during our

review of the Emergency

Condenser modifications.

In view of this,

and recent

problems with the fai lure of a contractor to properly perform post welding

hydrostatic testing of a primary containment penetration

(Inspection 86-10), it

appears

that the violations identified during this team inspection

may not be

an isolated problem.

Therefore,

as

we discussed

in a July 2,

1986 telephone call with Mr. W. Hanson

of your staff,

we request that you include in your response

the steps

you plan

to take to evaluate

the

scope of contractor

gC deficiencies;

your plans fo'r any

re-inspection of suspect

systems;

and your evaluation of the safety implica-

tions resulting

from inadequate

inspections

by your contractors.

Based

on discussions

with members of your staff at the exit meeting

on June

13,

1986, it is our understanding

that the upgrading of the engineering

assurance

procedures

for Nine Mile Point Nuclear Station will be completed

by October

1986

and will be used for modification design related activities planned for the

next refueling outage.

We also understand

that you plan to complete your

evaluation of the total loads

on the

AC and

DC emergency

busses

by June

1987

and that in the future you will maintain

an

up to date compilation of all

safety related electrical

loads.

In addition,

we understand

that you will

review these

loads to ensure

the assumptions

made in the safety analyses

are

not violated.

If our understanding

of your activities and schedules

related to

the upgrading of the engineering

assurance

procedures

or your evaluation of the

loads

on the

AC and

DC emergency

bus loads is incorrect,

then

we request that you

notify us as

soon

as practical.

The responses

directed

by this letter and the accompanying

Notice are not subject

to the clearance

procedures

of the Office of Management

and Budget

as requi red

by the Paperwork Reduction Act of 1980,

PL 96-511.
