b Enclosure 1 NOTICE OF VIOLATION Boston Edison Comoany Docket No. 50-293 Pilarim Station License No. DPR-35 During an NRC inspection conducted on February 25 through April 18,1998, three violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions, "NUREG-1600", the violations are listed below:

1. Pilgrim Technical Specifications, Section 6.8, " Procedures", requires that written procedures be implemented for activities covered by Regulatory Guide (RG) 1.33, Appendix A. RG 1.33, Appendix A, Section 9, " Procedures For Performing Maintenance," requires that maintenance be performed in accordance with written procedures or instructions that are appropriate to the circumstances. BECo procedure 1.5.20," Work Control Process," step 7.4.2[5] specifies that work plan details shall be commensurate with the complexity of the task.

Contrary to the above, the work plan to replace the external cooling water flexible hoses to the "A" core spray pump motor was not commensurate with the complexity of the task. As a result, physical damage occurred to an internal upper motor cooling coil resulting in significant rework and additional worker radiation exposure.

This is a Severity Level IV violation Supplement 1.

2. 10 CFR 50, Appendix B, Criterion Ill, " Design Control," states that measure shall be established to assure that the design basis of components are correctly translated into procedures and instructions. These measures shallinclude provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such documents are controlled.

Contrary to the above, the design basis of a component was not correctly tr.mslated into procedures in that Field Revision Notice 94-02-27, which installed the new "A" salt service water pump motor, did not address the unique configuration of the pump pedestal (weld pads). As a result, the pump motor shaft failed twice in 1997 due to misalignment of the pump and motor.

3. 10 CFR 50, Appendix B, Criterion XVI, " Corrective Actions," states that, measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, defective material and equipment, and non-conformances are promptly identified and corrected.

Contrary to the above, the NRC identified that appropriate measures were not being implemented to assure prompt identification and correction of several conditions adverse to quality, including:

ADOCK 05000293 PDR  ;

1. a broken conduit on the high pressure coolant injection system turbine that exposed and stretched electrical leads for an oil temperature alarm;

2. a leaking instrument air line supply for valves in the spent fuel pool system;

3. an oil leak caused by a defective weld in the "A" reactor recirculation system motor generator (MG) set oil line;

4. excessive vibration in an oil line on the "A" reactor recirculation set MG set caused by a loose U-bolt piping clamp;

5. loss of operating status indication light on the local electrical switchgear for the "B" fluid drive oil pump for the "B" reactor recirculation MG set, this condition existed for 3 days and went undetected; This is a Severity Level IV violation (Supplement 1)

Pursuant to the provisions of 10 CFR 2.201, Boston Edison Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region 1, and a copy to the NRC Resident inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for each violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation or severity level, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved. Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response. If an adequate reply is not received within the time specified in this Notice, an order or a Demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.

If you contest this enforcement action, you should also provide a copy of your response to the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001.

Because your response will be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction. If personal privacy or proprietary information is necessary to provide an acceptable response, then please provide a bracketed copy of your response that identifies the information that should be protected and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of withhold-ing (e.g., explain why the disclosure of information will create an unwarranted invasion of

I t

3 personal privacy or provide the information required by 10 CFR 2.790(b) to support a l request for withholding confidential commercial or financial information). If safeguards I information is necessary to provide an acceptable response, please provide the level of

l. protection described in 10 CFR 73.21.
