6 1979 In that order we indicated the four matters of concern 7

to the Board which had been set forth in our order of November 8

30, 1979, and equested that the parties furnish immediately 9

in many cases or as soon as possible documentary infor:ution 10 and other data which the Board daccad necessar/ for it to mahs' 11 a decision as to the continued or rect _med interin operation 12 of the Trojaa nuclear facility.

The facility is doun and has 13 been down since October for reasons stemminc initially from g

14 some repairs that were required for the stonn supnly system 15 but other matters have como up in the ncantine which vill be 16 addressed.

17 In the !!otaco of !! earing we advised the parties 18 and the pt ~olic that we considered that the public ( 'terest 19 required the e=peditious consideration and resolution of those 20 issues which were either expressed or implic?.t in our order 21 f November 30, 1979, the triggering order.

We indicated 22 that they had be en addressed by the parties in subsequent b

filings, that a hearing would be held on these matters,

which we have just concluded, which will pats upon the signi-3 ficance of the information thus, supplied, which will pass upon u

Th re has been scr.c updating on that l

13 There was a detailed report dated November 13, 14 1979 entitled "Neuly discovered problems with reaction forces 15 on certain concreto block or non-shear walls at Trojan,"

16 which had been furnished b'/ the Staff to the Doard and to the 37 parties, and l' gave cortain information.

18 The order of November 30,1979, further stated 39 that the noard took cognizance of the fact that I&B was 20 performing its own independent responsibility and had entered 21 a letter at any rate to the effect that operations should not 22 resume until their studies had been completed, but we indi-W.. *

asked the Staff further to give a juctificction cnd an e:c-gi planation for any further slippage in regard to its completion 12 13 and filing of its SER.

We asked all parties to state and to document 14 their reviews cs to how long interim cperation of the Trojan 15 facility chould be parmitted in the absence of the submission 16 of firm or final plans for control room modifications which g7 w uld be adequate from the safety standpoint to bring the 18 facility into substantial compliance with its licence.

That's the evidentiary record on which these 13 14 motions were considered by the Eoard.

15 The first question that arose portains in a sense 16 to jurisdiction or poucr of the Docrd.

The pocition uas 17 taken in certain rcepects, at least by the staff, the Licensee 18 and the State of Oregon, that the interir. hearing and the 19 Partial Initial Decision on interin operation divested the 20 Board to a certain extent of continuing jurisdiction.

21 He don't think it necescary to get in detail into 22 some of these natters because we think our ruling is not D

23 necessarily bottomed upon this question of jurisdiction, but y

says the Commission, are deemed waived until June 1,1979.

So when they were speaking of interim operation, it is very ovident that that interim was one of rather short g

11 And that is why we have indicctsd that we regcrd l

l 12 interim operation as being time limited and that the terminal 13 period is fast approaching.

14 Now, in order to accomplich an end of interim, it i

15 is the decision of this Board that will be expanded upon by 16 Dr. McCollom, that interir operation may be resumed, but in 17 order to insurc that we are not going to have interim regarded 18 or handled otherwise than as temporary, we have decidei first gg of all we are going to ret a firm date for the co:.mencement 20 of the evidentiary hearing on Phasa Two, where we go into the 21 ocope and timeliness and -- of modification required, and y

that timeliness has meaning, for April 1, 1980.

g We intend to start April 1, 1980.

How in order to do that, the parties are going to have to speed up very y

g substantialjy and very materially their preparation for trial.
