EQUIPMENT CLASSIFICATION FOR ALL OTHER SAFETY-RELATED COMPONENTS: '

LIMERICK-1/-2

1. INTRODUCTION 9

On February 25, 1983, both of the scram circuit breakers at Unit I of the Salen Generating Station failed to open upon an automatic reactor trip signal from the reactor protection system. This incident was terminated g manually by the operator about 30 seconds after the initiation of the automatic trip signal. The failure of the circuit breakers was determined to be related to the sticking of the undervoltags trip attachment. Prior I

to this incident, on February 22, 1983, at Unit 1 of the Salem Generating l Station, an automatic trip signal was generated based on steam generator t

low-low level during plant start-up.. In this case, the reactor was tripped y

[ manually by the operator almost coincidentally with the automatic trip.

uim L Following these incidents, on February 28, 1983, the NRC Executive Director for Operations (EDO) directed the staff to investigate and report

, on the generic implications of these occurrences at Unit 1 of the Salem Generating Station. .The results of the staff's inquiry into the generic i

implications of the Salem Unit 1 incidents are reported in NUREG-1000,

" Generic Implications of the ATWS Events at the Salem Nuclear Power plant." As a result of this investigation, the Commission (NRC) requested (by Generic Letter 83-28 dated July 8,1983 1

) that all licensees of operating reactors, applicants for an operating license, and holders of construction permits respond to the generic issues raised by the analyses of these two ATWS events.

This report is an evaluation of the responses submitted by the Philadelphia Electric Company, the licensee for Unit No. I and the applicant for Unit No. 2 of the Limerick Generating Station, for Item 2.2.1

' of Generic Letter 83-28. The documents reviewed as a part of this L evaluation are listed in the References (Section 11) at the end of this

[ report.

3. ITEM 2.2.1 - PROGRAM i 3.1 Guideline s

Licensees should confirm that an equipment classification program is

'in place that will provide assurance that safety-related components are designated as safety-related on plant documentation. The program should ,

provide assurance that the equipment classification information handling system-is used so that activities that may affect. safety-related components are designated safety-related. By using the information handling system, personnel are made aware that they are working on safety-related components and are directed to, and are guided by, safety-related proceoures and constraints. Licenses responses that address the features of this program '

are evaluated in the remainder of this report. i

,1 3.2 Evaluation -

v The licensee (applicant) for the Limerick Generating Station provided responses to Generic Letter 83-28 on November 10, 1983,2 May 29, 1985,3 June 7,1985,' and April 13, 1989.5 These submittals describe the safety related equipment classification program and its Q-List and Quality -

. Assurance Drawings. In the review of the licensee's response to this item, it was' assumed that the information and documentation supporting this program.is available for audit upon request.

i I

The licensee should confirm that their program used for equipment classification includes the criteria used for identifying components as safety-related.

'l 4.2 Evaluation .

]

1 The Itcensee's submittals provide the classification criteria used to determine whether a structure, system, or component is safety-related. I These criteria encompass the-criteria given in'the footnote to Section 2.2.1 of-the generic letter. Administrative Procedure A-129.2,

" Classification-and Engineering Evaluation of Items and Off-Site Services,"

directs the process of determining the safety classification and '

. procurement level of components not previously classified.

i 4.3 Conclusion ,

5. ITEM 2.2.1.2-INFORMATI00HANDLINGSYSTEM 5.1 Guideline .

The licensee should confirm that the program for equipment classification includes an information handling system that is used-to '

identify safety-related components. Tha response should confirm that this information handling system includes a list of safety-related equipment and ,

that procedures exist to govern its development and validation; -

5.2 Evaluation The licensee's response identifies the information handling system as consisting of the Limerick Project Q-List which is a single controlling '

document that identifies those systems and components that are

,g safety related. All safety-related components are identified as safety-related on Quality Assurance Drawings. The licensee has provided a j detailed description of the process for making changes.to the Q-List and how the list is maintained and distributed. The licensee will have incorporated all safety related components into the Q-List by the end of 1990.

5.3 Conclusion The licensee's responses describe a system that meets the

' recommendations of this item. Therefore, we find the licensee's responses for this item acceptable.

ITEM 2.2.1.3 - USE OF THE EQUIPMENT CLASSIFICATION LISTING

- F 6.1 Guideline The licensee's description should confirm that the program for equipment classification includes criteria and procedures that govern how station personnel use the equipment classification information handling system to determine that an activity is safety-related. The description shoul.d also include the procedures for. maintenance, surveillance,, parts replacement, and other activities defined in the introduction to 10 CFR 50, Appendix B.

6.2 Evaluation The licensee's response states that safety-related activities are conducted in accordance with Administrative Procedure A-26, under the I maintenarce request form (MRF) system. The MP.F system uses an equipment database management system (the Computerized History and Maintenance Planning System [ CHAMPS]) to prepare the MRF. The CHAMPS will not P

automatically insert the Q-list status of the component into the MRF; Plant Maintenance Staff Engineers consult a controlled hard copy of the Q-list and other documentation and enter the safety-related status onto the MRF.

Surveillance procedures are conducted in accordance with Administrative Procedure A-43, " Surveillance Testing Program." Other activities use the MRF system in accordance with Administrative Procedures A-41 and A-23,

" Generation of Special Procedures," and Administrative Procedure A-37,

" Procedure for the Control of Instrument Setting Changes."

6.3 Conclusion We find that the licensee's description of plant administrative controls and procedures meets the requirements of this item. Therefore, we find the licensee's responser for this item acceptable.

7.1 Guideline The licensee should briefly describe the management controls that are -

used to verify that the procedures for the preparation, validation, and routine utilization of the information handling system have been, and are .

being, followed. .

7.2 Evaluation '

The licensee's response specifies that the control, handling, and use of the Q-list and associated activities are verified through audits and  ;

surveillance to show that procedures for the preparation and use of the Q-list have been followed. The Engineering and Research Department Quality .1 Assurance Section audits Q-list activities at least every two years to determine that the Q-list has been maintained and used. Further management-assurance is~provided by th'e Electric Production Department Quality Assurance Division, which audits the Engineering and Research Department Quality Assurance Section at least every two years to ensure that Q-list.

activities are properly conducted. Routine audits of plant procedures and i the MRF system assures that plant activities regarding safety-related equipment are properly implemented.
