Gentlemen:

Subject: Inspection No. 50-334/88-08

This refers to the special operational safety inspection conducted by a tecm

of NRC personnel led by Dr. P. K. Eapen of this office on March 21-April 1,1988

at the Beaver Valley Power Station Unit No. 1, Shippingport, Pennsylvania of ,

activities authorized by NRC License No. OPR-66 and to the discussion of our

findings held by Dr. Eapen with you and members of your staf f at the conclusion

of the inspection.

Areas examined during this inspection included systems and plant personnel

actions required to mitigate the consequences of several accident sequences

which have the potential to result in core melt. The systems and accident

sequences were selected from generic probabilistic risk studies for pressurized

water reactors and ware modified to reflect specific features at Beaver Valley

Power Station Unit No. 1. The systems selected for this inspection were the on

site and off site electrical power system, emergency core cooling system,

and the auxiliary feedwater system. The inspection focused on the availability

of critical components in the above systems as evidenced by plant conditions,

-

operating experience, and the implementation of surveillance and maintenance

programs. In addition, this inspection assessed the ability of the licensee

staff to use procedures and equipment to respond to and recover from certain

'

postulated accidents. The assessments were made by conducting procedure

walkthroughs with licensee personnel in the facility and by observing the

performance of qualified licensee personnel during selected scenarios on the

licensee plant specific simulator.

Within these areas, our inspectors examined selected procedures and

representatives records, conducted interviews with personnel, inspected plant

equipment and observed personnel actions during simulated accident scenarios.

These areas are described in the NRC Region I inspection Report which is

enclosed with this letter.

OveraT1, the results of this inspection indicate that the plant equipment and

licensee staff are capable of reliable response to loss of onsite and offsite

power events and to loss of coolant accidents. This conclusion assumes that

the existing management initiatives and maintenance efforts to reduce equipment

down time will continue in the future. The inspection report summarizes other f

positive attributes such as senior management initiatives to maintain high

reliability for plant equipment, and highly capable operations, maintenance

and engineering personnel.

Based on the results of this inspection, it appears that certain of your

activities were not conducted in full cor,nliance with the NRC requirements, as

set forth in the notice of violation, enclosed herewith as Appendix A. This

violation has been categorized by Severity Level in accordance with the General

Statement of Policy and Procedures for NRC Enforcement Actions, 10 CFR Part 2,

Appendix C (Enforcement Policy 1987). Your are required to respond to this

letter and in preparing your response, you should follow the instructions in

Appendix A.

In addition, the team identified three unresolved items requiring action.

Two of the unresolved items discuss an apparent lack of documented basis for

1) maintaining the containment pressure between 8.9 psia and 14 psia during

LOCA accidents, without assuring that the low head safety injection pumps will

have sufficient net positive suction head (NPSH) at 8.9 psia, and 2) not incor-

porating several of the vendor recommendations in the plant procedures for the

turbine driven auxiliary feedwater pump. The third unresolved item discusses

the inability af the existing vibration monitoring program for pumps to provide

consistent readings and to detect possible degradation between tests. Please

provide details of the actions you plan to take to resolve these items with

completion dates in your response to this letter.

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

required by the Paper Work Reduction Act of 1980, PL 96-511.

Your cooperation with us in this matter is appreciated.

Sincerely,

Or.isinal Sisued ry t
