( ,s. NRC Staff Request for Additional Information 1. When qualifying supports with test data, you must show that the support displacements are not going to cause impact damage or render any cable not functional. 2. When a support cannot be qualified by test data, then an analysis of the support will be performed using alternate criteria. 3. A detailed check list should be used to fully document why each support is qualified when comparing to one of the configurations tested. Include the number and size of trays, length, height, bracing, hardware, dead-load weight, etc. f 4. Clearly reference in the program any documents that the NRC has already reviewed and accepted to eliminate reviewing them again. 5. Document in the program how the longitudinal displacement of the cable tray supports fDPm the test will be used to qualify as-built configurations. 6. Document in the program that horizontal bracing is better than diagonal bracing.

e lo -2 7. Review the cable tray records to determine if any of the cable trays exceed the 40% volume limit for 100% full. 8. Discuss the basis for the quantity of individual connection tests performed. 9. Provide additional detail on connection test procedure and results including applicability to analytical models.

10. Provide examples of supports which are qualified directly by test.
11. Document the member stresses recorded during the dynamic tests.
12. What approach is used to address M in cable tray supports.

SUBJECT:

Meeting Summary On March 19, 1986, representatives of PSNP and others met with the NRC staff to present and discuss the applicant's proposed cable tray qualification program. Attendees are listed in Enclosure 1. are the handouts which the applicant used to present and discuss the applicant's proposed cable tray qualification program. A At this meeting the applicant committed to provide the following information for staff review: a) Responses to NRC request for additional information (RAI) resulting from discussions during this meeting (The RAls are listed in ), b) The Program Peport that provides details on dynamic testing, connection testing, test input, analytical techniques and qualification documentation, and c) Provide a copy of the ANC0 I.aboratory Test Report, which contains test procedures, inputs and results of all dynamic testing. At the conclusion of the applicant's presentation and discussions pertaining to the presentation, the staff indicated that provided the staff received the information the applicant committed to formally provide and the staff confirmation of the adequacy of that information they considered the applicant's Cable Tray Support Qualification Program as acceptable.
