4 CALLAWAY PLANT, HNIT 1 GENERIC LETTER 83 7R, ITEM 7.7 (pADT 11 EQUIPMENT CLASSIFTCATION IPD0 GRAMS FOR ALL 5AFET) RELATED COMPONENTS)
TNTRON'CTION AND
SUMMARY
.g Generic Letter 83-98 was issued by th'e NDC on.1uly 8, 1983,.indictting actions to be taken by applicants and licensees based on the generic implications of the Salem ATWS events.
Item 2.? (part li states a sta'f position which r ui res licensees and applicants to describe their program f.or ensurino that all componer.ts of sa'ety-related systems necessary for accomplishing required safety functions are identified as safety-related on informational and procedural materials. The licensee's submittal is required to specifically describe five sub-items pertaining to (1) the criteria for identifying components as safety-related; (5) the infor-mation handlino system used to identify safety-related components; (31' tbe way in which station personnel use the information handling system; (d) the management controls used to verify that the procedures for preparation, validation and util-ization of the infomation handling system have been followed; and (5) specifi -
cations for procurement of t?.4ty-related components.
The licensee for the Callaway Plant, Unit 1, submitted responses to item 2.?
(part 1) of Generic Letter 83-28 by letters dated November 18, 1083; March 12, 1484; May 71, 198a; December 27, 1984; and January 27, 19R7 Our evaluation of these responses find then to be acceptable.

P
..O 9-EVALUATION The licensee identifies the r)-List and the Computerized History and Maintenance Planning System (CHAMPS) as the informational sources for identifyino safet"-
related components. Work requests identify when equipment is sP fety related, and designate the procedures to be used for safety-related activities.
Addi-tionally, safety-related components are identified as such on desian drewinas, in the Final Safety Analysis Peport, and on referenced procedures.
The licensee responses to the five sub-itens of Iten 2.? (Part 1) will be in-dividually discussed and the five then considered in combination.
1.
Criteria For Identifyina Safety-Related Components The licensee indicates that the criteria for identifyino safety-related components is essentially the same as those described in the SNUDPS (Standardized Nuclear Unit Power Plant System) environmental qualification program for the electrical equipnant list.
7 Information Handlino System The licensee's submittals identify the "0-list" as a compilation at the component level of all the equipnent incorporated within the SNUPPS design.
The SNUPDS safetv-related components have been identified by the Architect Engineer (Rechtell and by the Nuclear Steam Supply vendor (Westinghousei.
Union Electric through its representatives on the SNUPPS Technical Conmittee
has the overall desion review responsibility. The 0-list is developed in accordance with SNUPPS Administrative Control Procedures and compliance with these procedures are audited en a recular basis.
3.
Use of the Information Handlino Svstem The licensae states that maintenance planning personnel use the onsite Cogputerized Pistory and Maintenance Planning System (CHAMDS), which contains the safety-related components of the 0-List, to determine when a component is safety-related.
It identifies the procedures to be used for maintenance work, routine surveillance testing and other mainten-ance and testing activities. The CHAMPS is consulted before any maintenance, testina, design changes, engineerino support, setpoint changes or special tests or studies are initiated.
4 Manacerent Controls The license
- states that the 9-List will be controlled, maintained and updated in accordance with the SNUPPS DA program procedures. The Pechtel, Westinohouse, and SNUPPS components of the 0-list are subiect to internal licensee audits as part of the SNUPPS DA program. The procedures are sub-ject to audit by the quality assurance department. The licensee also states that written procedures will call for routine use of the 0-list.

.t-5.
Procurenant Specifications The licensee's submittals stata that specifications 'cr safety-related components include outlification testina and analysis for environmental conditions. These tests and analyses are documented in a historical f i 'i e. The qualified lives for equipment and preventative maintenance activities are included in the licensee's surveillance and maintenance program. The licensee states that specifications imposed by administra-tive procedures on safety-related items specify the appropriate technical and quality requirements, including environmental and seismic testing.
Our review cf the licensee's responses to the five sub-itens of item 2.2 (Part
- 1) of Generic Letter 83-?8 finds that the licensee has an adecuate orocram to classify and document safety-related components and to utilize this documentation for safety-related activities, including repair, maintenance, surveillance testfnq and procurement.
CONCLUS!0N Our review of the licensee's responses to item 7.? (Part II of Generic letter 83-28 for the Callaway Plant, Unit 1, finds that the licensee has an adecuate program for classifying safety-related components and for controlling safety-related activities. We find the licensee's responses are consistent with the staff position of the generic letter and are acceptable, i
