BOARD NOTIFICATION REGARDING ASCO SOLEN 0ID VALVES FOR V0GTLE UNITS 1 AND 2 (80ARD NOTIFICATION NO. 86-lI)
In accordance with the NRC procedures for Board Notifications (BNs), this BN is being provided to forward infonnation pertinent to the Vogtle contention the qualification of A3C0 solenoid valves. By letter cated August regarding(enclosed),
12, 1986 the staff forwarded a request for additional infonnation on the applicant's main steamline break (MSLB) analysis. The staff's request in part questioned the applicability of the methodology used for the qualification of ASCO valves exposed to superheat conditions following an MSLB outside of containment.
The applicant has infonned the staff that ' documentation discussing ASCO valve qualificaticn would be forwarded in approximately one week for staff review.
The staff will infonn the Bcard of final resolution of this issue promptly.

Dear Mr. Conway:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION ON CONFIRMATORY ITEM 9, "STEAMLINE BREAK ANALYSIS OUTSIDE OF CONTAINMENT" By letter dated June 25, 1985, Georgia Power Company submitted an analysis of steamline breaks outside of containment in response to confirmatory item 9. The staff has ' reviewed this submittal and requires additional information detailed
- in the enclosure to complete its review.
The staff suggests a meeting during the week of August 25 to discuss the issue with your staff. I will contact your staff to finalize arrangements.
If there are any questions, I can be reached at (301) 492-7357.
Sincerely, Melanie A. Miller, Project Manager FWR Project Directorate #4 Division of PWR Licensing-A

ENCLOSURE N REQUEST FOR ADD.ITIONAL INFORMATION
, V0GTLE ELECTRIC GENERATING PLANT, UNITS 1 AND 2
, MAIN STEAM LINE BREAK OUTSIDE CONTAINMENT -
The staff has reviewed the applicant's June 25, 1986 submittal concerning '
the MSLB analysis outside containment. Th~e staff believes that the therrral analysis presented in Attachmerit 2 of the June 25, 1986, submittal requires further justification. The specific concerns'are discussed below:
- 1. The staff finds that the Westinghouse approach for calculating the time a component remains at saturation temperature may not be appropriate. Section 3.2.2 of Attachment 2 to the June 25 submittal describes the Westinghouse model. Equation 2 in Section 3.2.2 is given as:
m Ah, = in 3h d t w ith terms defined in Section 3.2.2. The Westinghouse model further specifies' that m = mass cf water on component -
= 0.021 lb
'm mass flowrate of steam impinging on component
= 0.71 lb/hr 4
2 .
Therefore, Equation 2 becomesA = b.0296 Ah,/h 3
, which implies that the time at saturation (4t) is a function of enthalpy only; this is contrary to the physical meaning of the original equation which says that 4t is a function of In and m. Additional information is needed to justify that 4t is independent of flow conditions, heat transfer, and the configuration of the component.
- 2. The staff has also reviewed other documents cited by the applicant in the June 25 letter, namely, WCA."-8687, Supplement 2. "ASCO Solenoid Valve l Qualification t'o a Derated Westinghouse Generic LOCA/MSLB Profile," and h0 REG /CR-3424, " Test Program and Failure Analysis of Class IE Solenoid Valves."
The staff notes that there is insufficient data to support the general applica-bility of' Equation 2. In WCAP-8687, Supplement 2, Westinghouse used one set of test data from MUREG/CR-3424 to calculate m and In for one component. This empirical approach is unique to that component for the test conditions. This
~
test cannot be extrapolated to other components, under different flow conditions.
The applicant should provide further jurtification to support the general application of Equation 2.
- 3. Similarly, Equation 1 in Section 3.2.1 of Attachment 2 of the June 25 letter, with a constant value of Q equal to 4.29 Btu /sec, does not appear acceptable for calculating t other than for the specific component and test condition under which the value Q was derived. The applicant should provide further justificaticns for use of this equation in other applications.

- 4. Theequation(=[Acomponen't ', *
(
A 8316 is stated by Westinghouse without proof. The applicant should provide further justification concerning the applicability of this equation.
- 5. It appears to the staff that the complicated vaporization process in a superheated environment with strong blowdown flow has been overly simplified by the Westinghouse model. The acceptability of the Westinghouse approach, which, in effect, uses one set of test data to derive a generic equation, is questionable. If the applicant continues to promote .this approach, further justification is needed.
- 6. The Westinghouse model is not consistent with staff recomendations in NUREG-058'8, Appendix B. The applicant should provide a thermal analysis using the methodology of NUREG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," or provide explicit justification for an alternative approach.
