ANSWER 0F AEC REGULATORY STAFF T0
" MOTION.OF MAPLETON INTERVENORS REGARDING VISIT TO NATI0llAL REACTOR TESTING STATION, IDAHO, AND DEPOSITIONS RE ECCS TESTS" l
On October 7,1971, the Mapleton intervenors served a motion for an order (1) directing-the AEC regulatory staff to produce " copies of all documents and data which will be relied cpon in its reevaluation of the emergency core cooling system of the proposed Midland Plant, including, but not limited to, the documents and fata relating to Tests 845-850 and the results of the series of experiments conducted for the AEC at its National Reactor Testing Station in Idaho, in flovember and December of 1970,"
and (2) authorizing the intervenors _"to visit the hational Reactor Testing Station....., to take the depositions of the personnel who conducted such
/
tests and experiments, and to examine and receive copics of the documents and data. generated by such tests and' experiments."
We have not yet completed our reevaluation of emerconcy core cooling system (ECCS) effectiveness with respect to the Midland Plant.
We are, at this time, still awaiting the applicant's response to our letter of-July 14, 1971, requesting additicnol information relating to the applicant's

2-proposed ECCS.
Accordingly.the Mapleton intervenors' general request for all documents relied upon by the staff in this reevaluation is premature
.and'should be denied.without prejudice to' renewal at an appropriate time
~
O after the staff's reevaluation is completed As regards the ECCS semiscale tests 845-850, we would point'out that
- extensive infonnation on these tests is already available to the inter-venors.
By letters dated May 21' and' June.10,1971, we transmitted to the Board and all~ parties copies of six Idaho ~ t!uclear Corporation nonthly reports-containing information on the semiscale testsk Additionally, during the course 1of the' hearing in July, l'971 (Tr. 3707-08), ve made available t;o the Board and all parties bopies 'of the Idaho fluclear Corporation document, "Semiscale Tests 845 through 851,"' dated Jun'e 29, 1971, wh'ich sets forth-detailed test data, including a description of the single-loop semiscale
. system, a discussion of theitest series, a compilation of selected digi-2
~ tized- ~ data--for each of. the. tests, aqd a brief description of the computer
-. codes used:for ~ analysis of the ~ test results.
Further pertinent information,'--
inclu' ding presentations' by personnel involved.in the conduct of the.
~
- semiscale -tests, is -set forth in the transcript of the 1971 annual Atomic jf. We would also point out that motions"for the prnduction of documents'
' by the staff must be filed under-10 CFR 2.744-and cinnot be filed under 110'CFR 2;741, the section. invoked by the Mapleton intervenors.
2/ Welshall'soon transmit to the Board and all parties copies of four
- subsequent monthly, reports.

available for/publicl inspection at the-AEC Public Document Room,1717 -

n The-Conmission's regulations in 10 CFR 2.740' require a showing of " good Jcause" in~ connection with a motion for the taking of depositions. Consider-Ling the ' availability of above-mentionbd sources of inforniat. ion on the semi-1 scal'c Jtes ts,.we belicve that t.he. _intervenors have not shotin. good caust-
'for the taking of. depositions at ;the National Reactor' Testing Station.
In ou'r view, zthe 'available information is adequate to. enable a properly quali-fied individual to; understand the tests and 'to evaluate their significance, if any, with respectato the Midland: plant ECCS. design.
[For~t'he foregoing reasons, w'e respectfully request-that the'liapleton inter-venors' motion be~ denied.
