LICENSEE'S ANSWERS TO F0E'S INTERROGAT'ORIES SERVED SEPTEMBER 25. 1978 General Electric (GE) hereby responds-*/ to Friends of the Earth's (70E's) interrogatories , served September 25, 1978, which were received by counsel for GE on September 28, .

1978, as follows:

1. Detrimental effects from radiation in the piping materials in systems required for safe shutdown of the GETR in the case of the mmem"m postulated seismic event have not been observed during the 21 years since the GETR's construction.

• / GE is furnishing these responses in the hope of expediting this proceeding. In doing so, GE has purposefully limited its obj ections only to the most obvious cases, and unless otherwise noted, GE does not concede either (a) that the infor ation sought by any of the subj ect interrogatories is relevaat to any of the three specific issues identified in the Cocnission's i

Memorandum and Order, dated February 13, 1978 (Cf. Tr. 36-87),

to which the inquiry in this proceeding is lisiEed, or (b) that this information is even reasonably calculated to lead to the discovery of admissible evidence. Cf. 10 CFR

2. Ti:e original piping design for the piping required for safe shutdown of the GETR in the case of the taxicus l postulated seismic event was based on the code noted in response to Interrogatory 6. The new piping restraint designs were based in part on ASME Section III values; specific references used are enumerated in EDAC report 117-217.05.

3. No.

4. No erosion ha's been observed in the pipe or pipe walls required for the safe shutdown of the GETR in the case of the mavdmum postulated seismic event, nor have significant amounts of corrosion been found.

5. The original piping specifications are described in the specifications for the construction of the General Electric Test Reactor at Pleasanton, California, September 1957, R. M. ? arsons Cocpany. Piping corrosion is not normally a design factor for aluminum piping carrying demineralized water at low temperature; allowances for corrosion for the original piping design are not known.

6. The code employed for the original piping design for GETR was American Standards Association, Code for Pressure Piping, ASA 331.1-1955.

Friends of the Earth contact Mr. W. T. Crawford at the I l

Vallecitos Nuclear Center in order to =ake the necessary a

arrangements for such inspection and copying. Reproduction i

copying at GE's customary rate.

l 8. The rigid-body motion was considered in the analysis of potential sliding and tilting of the reactor building. \

l

! The model for the rigid-body motion is described in l EDAC reporr 117-217.03 which has been forwarded to all parties.

9. Yes.

1 10. The original piping was designed to the code referenced in response to Interrogatory 6. Installation stress lead cacacities in the GETR pipes are not known to have been measured, and this comparison with design values not nade, i 11. The GETR piping restraints required for safe shutdown ,

to assure that piping stresses are within allowable

[ values for a 0.8g peak ground acceleration and. a one meter surface offset. The'value of offset and vibratory ground motion at which these components would exceed their material deformation capacities has not been determined.

15. The flexible connections, at the locations where the fuel flooding system piping penetrates the GETR conen +nment , are provided in order to prevent loading ,

the piping during a seismic event. This is the only piping that penetrates the containment which is required for the safe shutdown of the GETR in the case of the maximum postulated seismic event and is described in EDAC report 117-217.08.

16a. The original piping supports for systems required for safe shutdown of the GETR in the case of the naximum postulated seismic event have been supplanted by new restraints which have been or are being installed.

These are described in EDAC reports 117-217.05, 117-217.06, and 117-217.07 previously sent to'all parties.

18. The piping support anchors for the piping systems required for the safe shutdown of the GETR in the case of the mav4== postulated seismic event are described in l l

EDAC reports 117-217. 05, 117-217. 06 and 117-217. 07 previously senti to all parties. ,

19. The proposed modified piping supports will be installed prior to reacton startup.

20. The new piping supports adhere to the Quality Assurance a

requirements described.in the Safety Analysis Report, NELO 12622 which has been. forwarded to you. 10 C.F.R. 50, 4

Appendix 3 was used.as a guide in formulating the above quality assurance requirements.

21. The modifications that are planned in relation to systems required for the safe shutdown of the GETR in the case of the maximum postulated seismic event are described in the July 20, 1978 submittal (Darmittel to Stallo) copies of which were sent to all parties.

No piping replacements are necessary to sssure safe shutdown of the GETR in the case of the na:ci=um postulated seismic evenr. -.

22. GE does not plan to take photographs for verification of primary and secondary pipe and support locations ,

.. the original counting design, and pipe and support i modifications. However, photos of selected equipment i may be taken after modifications related to systems i

required.for the safe shutdown of the GETR in the case i

i of the maximum postulated seismic event have been s

completed.

j 23. No. The only access points for photography are the 4
