EQUIPMENT CLASSIFICATION (ALL OTHER SAFETY-RELATED COMPONENTS).
CALLAWAY PLANT, UNIT 1
- 1. INTRODUCTION On February 25, 1983, both of the scram circuit breakers at Unit 1 of
. the Salem Nuclear Power Plant failed to open upon an automatic reactor trip signal from the reactor protection system. This incident was terminated 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 undervoltage trip attachment. Prior to this incident, on February 22, 1983, at Unit 1 of the Salem Nuclear Power Plant, an automatic trip signal was generated based on steam generator low-low level during plant startup. In this case, the reactor was tripped manually by the operator almost coincidentally with the automatic trip.
Following these incidents, on February 28, 1983, the NRC Executive Director for Operations (ED0), directed the NRC staff to investigate and report on the generic implications of these occurrences at Unit 1 of the Salem Nuclear Power Plant. The results of the staff's inquiry into the generic implications of the Salem unit 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 ) all licensees of operating reactors, applicants for an operating Itcense, and holders of construction permits to 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 Union Electric Company, the licensee for the Callaway Plant, for Item 2.2.1 of Generic Letter 83-28. The documents reviewed as a part of this evaluation are listed in the references at the end of this report.

- 2. REVIEW CONTENT AND FORMAT Item 2.2.1 of Generic Letter.83-28 requests the licensee or applicant to submit, for the staff review, a description of their programs for safety-related equipment classification including supporting information, in considerable detail, as indicated in the guideline section for each .
sub-item within this report.
As previously indicated, each of the six sub-items of Item 2.2.1 is evaluated in a separate section in which the guideline is presented; an evaluation of the licensee's/ applicant's response is made; and conclusions about the programs of the licensee or applicant for safety-related equipment classification are drawn.

- 3. ITEM 2.2.1 - PROGRAM 3.1 Guideline Licensees and applicants should confirm that an equipment classification program exists which provides assurance that all safety-related components are designated as safety-related on all plant documents, drawings and procedures and in the information handling system that is used in accomplishing safety-related activities, such as work orders for repair, maintenance and surveillance testing and orders for replacement parts. Licensee and applicant responses which address the features of this program are evaluated in the remainder of this report.
3.2 Evaluation The licensee for the Callaway Plant responded to these requirements 2
, with submittals dated November 11, 1983 , March 12, 1984,3 May 21, 4
1984, and December 27, 1984 and .lanuary 27, 1987. These submittals 4
include information that describes their existing safety-related equipment classification program. 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. We have reviewed this information and note the following.
t j The licensee states that administrative procedures provide consistency between the Q-List and the Computerized History and Maintenance Planning i
System (CHAMPS), which are used to identify safety-related components. The licensee states that all work requests identify whether equipment is safety-related or not, and identify the proper work restraints.
Additionally, the licensee has stated that safety-related components are 4
' identified as such on design drawings, the Final Safety Analysis Report, work requests and referenced procedures.

- 5. ITEM 2.2.1.2 - INFORMATION HANDLING SYSTEM 5.1 Guideline 4
, The licensee or applicant should confirm that the program for i
. equipment classification includes an information handling system that is j used to identify safety-related components. The response should confirm
- that this information handling system includes a list of safety-related equipment and that procedures exist which govern its development and validation. ,
5.2 Evaluation The licensee's submittals identify the "Q-List" as the computerized index that identifies safety-related components. The description included
~
the methods and procedures used for lts development, verification and validation.
I 5.3 Conclusion We find that the information contained in the licensee's submittals is ,
i sufficient for us to conclude that the licensee's information handling system for equipment classification meets the guideline requirements.
Therefore, the information provided by the licensee for this item is acceptable.

- 6. ITEM 2.2.1.3 - USE OF EQUIPMENT CLASSIFICATION LISTING 6.1 Guideline The licensee's or applicant's description should confirm that their-program for equipment classification includes criteria and procedures which govern how station personnel use the equipment classification information .
i handling system to determine that an activity is safety-related and what procedures for maintenance, surveillance, parts replacement and other activities defined in the introduction to 10 CFR 50, Appendix B, apply to safety-related components.
6.2 Evaluation The licensee states that maintenance planning personnel use the onsite Computerized History and Maintenance Planning System (CHAMPS), which contains the Q-List, to determine when a component is safety-related. It identifies the procedures to be used for maintenance work, routine surveillance testing and other maintenance and testing activities. The CHAMPS is consulted before any maintenance, testing, design changes,
! engineering support, setpoint changes or special tests or studies are initiated. '[
6.3 Conclusion We find that the licensee's description of plant administrative controls and procedures meets the requirements of this item and is, therefore, acceptable.
