December 31, 1979 Page 1 of 1 CONTROL OF MAINTENANCE AND ESSENTIAL EQUIPMENT Description of Circumstances:

Enclosed is a copy of a recent enforcement action against Duguesne Light Company. A copy of this action is being forwarded to all utilities with a power reactor operating license or a construction permit.

This is being done to apprise you of a serious condition which revealed an apparent weakness in facility control of maintenance and essential equipment.

You should review your existing procedures and control "for independent verifi-cation of operability of redundant counterpart equipment when an essential component, subsystem, or system is determined inoperable.

Operability is defined as follows:

A system, subsystem, train, component or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified function(s).

Implicit in this definition shall be the assumption that all necessary attendant instrumentation, controls, normal and emergency electrical power sources, cooling o.r seal water, lubrication or other auxiliary

. equipment that are required for the system, subsystem, train, component or device to perform its function(s) are also capable of performing their related support function(s).

I.f you have any questions regarding this matter, please contact the Director of the NRC Regional Office in which your facilities are located.

No written response to this IE Information Noti~e is required.

Letter to Duguesne Light Company from V. Stello, Jr., dtd. 12/5/79

Attachment to Informa-Notice No. 79-35 Docket No. 50-334 December 5, 1979 Duquesne Light Company ATTN:

Mr. Stanley G. Schaeffer President 435 Sixth Avenue Pittsburgh, Pennsylvania 15219 Gentlemen:

On November 27, 1979, the Beaver Valley Power Station, Unit 1, was operated for about two (2) hours in a condition which exceeded the Limiting Conditions for Operation.

This matter was brought to the attention of our inspector at your facility in a timely fashion, and your subsequent action to correct the condition was expeditious.

Nevertheless, this condition rendered a part of the emergency core cooling ~ystem (ECCS) unavailable for automatic start and injection of coolant into the reactor coolant system (RCS) if the need had occurred concur-rent with the loss of offsite power (the design basis). This unavailability of ECCS constitutes a serious matter which reveals an apparent weakness in your control of maintenance and essential equipment.

Therefore, we propose to impose a civil penalty for the item of noncompliance set forth in Appendix A to this letter in the amount of $5,000.

Appendix B is a Notice of Proposed Imposition of Civil Penalties.

You are required to respond to this letter and in preparing your response, you should follow the instructions in Appendices A and B.

In addition to the civil penalty, we are issuing the enclosed Order (Appendix C) effective immediately.

This Order requires that your administrative control of licensed activities involving operating and maintenance of safety equipment verifies availability of all required equipment when a counterpart is removed from an operable status. This Order further requires that you formally review and report your actions to prevent recurrence.

It also requires that you meet publicly on January 25, 1980, with the Director, Office of Inspection and Enforcement, at a location near the Beaver Valley Power Station, to discuss your evaluation of this conditon and your corrective actions to prevent recurrence.

We will inform you of the location and time of the meeting.

Attachment to Informa. Notice No. 79-35 Duquesne Light Company In ac~ordance with Section 2.7~0 of the NRC 1s "Rules of Pract1ce 11, Part 2, Title 10, Code of Federal Regulations, a copy of this letter and its enclosures will be placed in the Commission 1s Public Oocument Room.

Duquesne Light Company Pittsburgh, Pennsylvania 15219 Attachment to Informat~ Notice No. 79-35 APPENDIX A NOTICE OF VIOLATION Docket No. 50-334 License No. DPR 66 This refers to the inspecti'onconducted by the NRC Resident Inspector at the B.eaver Val 1 ey Power Station, Unit 1, of activities authorized by NRC License No. DPR 66.

During the inspection conducted on November 27, 1979, the following item of noncompliance was identified.

Technical Spec.i fication 3. 5. 2 states that with the pl ant in Mode 1 (Power Operation), two separate and independent ECCS subsystems shall be operable, and further states in section 3.5.2.c that each subsystem shall include an operable flow path capable of taking suction from the refueling water storage tank upon initiation of a safety injection signal.

Technical Specification 1.6 defines "operable 11 to include the assumption that all necessary attendant instrumentation, controls, electric power, cooling or seal water, lubrication or other auxiliary equipment that are required for the system, subsystem, train, component or device to perform its function(s) are also capable of performing their related safety function(s).

Contrary to the above, on November 27, 1979, from approximately 8:30 a.m. to 10:30 a.m., maintenance activities rendered both ECCS subsystems inoperable in that a) refueling water storage tank isolation valve MOV-CH-1150 was closed and incapable of automatic opening in response tQ a safety injection signal, and b) refueling water storage tank isolation valve MOV-CH-1158, in the redundant subsystem, was closed, had no emergency power available, and thus was incapable of automatic opening in response to a safety injection signal if there had been a condition of loss of offsite power.

This violation had the potential for causing or contributing to an occurrence related to health and safety (Civil Penalty $5,000).

Attachment to Infcirmat. *Notice No. 79-35 APPENDIX B NOTICE OF PROPOSED IMPOSITION OF CIVIL PENALTIES Duquesne Light Company Pittsburgh, Pennsylvania 15219 Docket No.

50-334 License No. DPR-66 This office has considered the e*nforcement options available to the NRC including administrative actions in the form of written notices of violation, civil monetary penalties, and orders pertaining to the modification, suspension or revocation of a license.

Based on these considerations, we propose to impose civil penalties pursuant to Section 234 of the Atomic.Energy Act of 1954, as amended, (42 USC 2282), and to 10 CFR 2.205 in the cumulative amount of Five Thousand Dollars ($5,-000) for the specific items of noncompliance set forth in Appendix A to the cover letter.

In proposing to impose civil penal-ties pursuant to this section of the Act and in fixing the proposed amount of the penalties, the factors identified in the Statements of Consideration published in the Federal Register with the rule-making action which adopted 10 CFR 2.205 (36 FR 16894) August 26, 1971, and the "Criteria for Determining Enforcement Action, 11 which was sent to NRC licensees on December 31, 1974, have been taken into account.

Duquesne Light Company may, within twenty (20) days of the receipt of this notice pay the civil penalties in the cumulative amount of Five.Thousand Dollars ($5,000) or may protest the imposition of the civil penalties in whole or in part by a written answer.

Should Duquesne Light Company fail to answer within the time specified, this office will issue an order imposing the civil penalties in the amount proposed above.

Should Duquesne Light Company elect to file an answer protesting the civil penalties, such an answer may (a) deny the items of noncompliance listed in the Notice of Violation in whole or in part, (b) demonstrate extenuating circumstances, (c) show error in the Notice of Violation, (d) show other reasons why the penalties should not be imposed.

In addition, to protesting the civil penalties in whole or in part, such answer may request remission or mitigation of the penalties.

Any written answer in accordance with 10 CFR 2.205 should be set forth separately from the statement or explanation in reply pursuant to 2.201, but may incorporate by specific reference (e.g., giving page and paragraph numbers) to avoid repetition.

Duquesne Light Company's attention is directed to the other provisions of 10 CFR 2.205 regarding, in particular, failure to answer and ensuing orders; answer, consideration by this office,. and ensuing orders; requests for hearings, hearings and ensuing orders; compromise, and collection.

Upon failure to pay any civil penalty due which has been subsequently determined in accordance with the applicable provisions of 10 CFR 2.205, the matter may be referred to the Attorney General, and the penalty, unless compromised, remitted, or mitigated, may be collected by civil action pursuant to Section 234.c of the Atomic Energy Act of 1954, as amended (42 USC 2282).

(Beaver Valley Power Station, Unit 1) )

ORDER MODIFYING LICENSE EFFECTIVE IMMEDIATELY I

Docket No. 50-334 The Duquesne Light Company (the 11 licensee 11 ) is the holder of Operating License DPR-66 (the 11license 11 ) which authorizes operation of the Beaver Valley Power Station, Unit 1, at steady state reactor core power levels not in excess of 2652 megawatts thermal (rated power).

The license was issued on January 30, 1976.

The facility consists of a pressurized light water moderated and cooled reactor (PWR), located at the licensee's site in Beaver County, Pennsylvania, on the southern shore of the Ohio River.

II On November 27, 1979, from about 6:30 AM to 1:20 PM while the reactor was operating at about 30% of rated power, Emergency Diesel Generator (EOG) 1 was*

. out of service for routirie maintenance.

This EDG supplies emergency power to suction valve, MOV-CH-1158, in the line from the refueling water storage tank (RWST) to the High Pressure Safety Injection System (HPSIS) pumps.

In addition to the EOG being out of service, resulting in loss of one Emergency Core Cooling System (ECCS) flow path, as described above, the redundant suction valve, MOV-CH-1150, was removed from service for maintenance which resulted in loss of the redundant ECCS flow path from the RWST from 8:30 a.m. to 10:30 a.m.

During this time the facility was operated in noncompliance with the Limiting Condition for Operation specified in ~echnical Specification 3.5.2.c. This condition resulted from inadequate control of maintenance activities and its

Appendix C Attachment to Informa.n Notice No. 79-35 occurrence suggests that the licensee has n6t adopted appropriate controls to assure that maintenance activities do not defeat required safety features.

This in turn undermines the basis for determining that there is reasonable assurance that redundant safety features will function under design basis conditions.

In view of the significance to safety of adequate controls to assure that maintenance activities do not defeat required* safety features, I have deter-mined that the public health, safety, or interest requires, effective immediately, modific~tion of License No. DPR-66 as stated in Part III of this Order.

III Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and the Commission's regulations in 10 CFR Parts 2 and 50, License DPR-66 is modified as follows:

(1) Administrative Procedures shall be adopted and implemented to require redundant independent verification of the operability of the remaining engineered safety features whenever any safety system, or subpart thereof, is intentionally removed from -service.

(2) A detailed review of existing procedures and controls shall be performed to assure that limiting conditions for operation are not defeated by maintenance or other activities.

(3) A report of the administrative procedures required by paragraph (1) above and the detailed review required by paragraph (2) above shall be submitted by January 11, 1980, to the Director of NRC's Region I office.

Attachment to Informa~ Notice No. 79-35 Appendix C

- 3.-

(4) The licensee shall meet with the Director, Office of Inspection and Enforcement, on or before January 25, 1980, in a meeting open to the public in the vicinity of the Beaver Valley site to describe how the above requirements will be implemented.

The Director, Region I, will inform the licensee at least one week in advance of the specific time and location of the meeting.

IV The licensee, or any other person who has an interest affected by this Order, may, within twenty-five days of the date -0f this Order, request a hearing.

A request for a hearing shall be addressed to the Director, Office of Inspection

- and Enforcement, U.S.N.R.C., Washington, D.C.

20555.

If a hearing is requested by the licensee or an interested person, the Commission will issue an Order designating the time and place of hearing.

Such~a request for hearing SHALL NOT STAY THE IMMEDIATE EFFECTIVENESS OF THIS ORDER.

Resumption of operation on terms consistent with this Order is not stayed by the pendency of any proceeding on this Order~ In the event that a need for further enforcement action becomes apparent, either in the course of any proceeding on this Order or at any other time, the Director will take appro-priate action.

v In the event the licensee or any other interested person requests a hearing as provided above and a hearing is held, the issues to be considered at such a hearing shall be:

Attachment to Informa~n Notice No. 79-35 Appendix C (1) whether the facts set forth in Part II of this Order are correct;

and, (2) whether this O~der should be sustained.
