Dear Mr. Wrinkle:
This is in reply to your letters of June 14, 1979 to ne and of June 24, 1979 to Chaiman Hendrie expressing concerns about the shutdown of the Rancho Seco nuclear power plant.
Enclosed is a copy of a letter of June 27, 1979 froa me to the Sacramento Municipal Utility District permitting resumption of operation of the Also enclosed is a copy of an Order of June 21, 1979 Rancho Seco plant.
by the ticclear Regulatory Commission directing the selection of a board to determine whether requesters of a hearing in this case meet the requisite personal interest test and to conduct any hearing which may be required.
Resuned operation of the Rancho Seco facility is not stayed by the pendency of these prcceedings.
We are mindful of the economic hardships that can cccur as a result of shutdowns of nuclear power plants and work as hard as we can to avoid any unnecessary delays in the resumption of operations while giving priority to our responsibilities _to ensure the continued protection of the health and safety of the public.
Sincerely, Jg '.,

Dear Mr. Mattimce:
Sy Order of May 7,1979, the Commission confirmed your ur.dertaking a series of actions, both immediate and long tern, to increase the capability and reliability of the Rancho Seco Nuclear Generating Station to resp nd to various transient events.
!n addition, the Order confirred that you w:uld shut dcwn Rancho Seco on April 28, 1979, and maintain the plant in a shut-dcwn condition until the following actions had been satisfactorily cccpleted:
(a)
Upgrade the timeliness and reliability of calivery Acm the Auxiliary Feedwater System by carrying out actions as icentified in Enclosure 1 of ycur letter of April 27, 1979.
(b)
Develop and implement operating procedures for initiatir.g and controlling auxiliary feedwater independent of Integrated Ccatrol System control.
(c)
Implement a hard-wired control-grade reactcr trip that would be actuated on loss of main feedwater and/or turbine trip.
(d)
Complete analyses for potential small breaks and develop and implement operating instructions to define operator action.
(e)
Provide for one Senior Licensed Operator assigned to the control room who has had Three Mile Island Unit No. 2 (TMI-2) training on the B&W simulator.
By submittal of May 14, 1979, as supplemented by seven letters dated May 22, 24,29,30(3) and June 6,1979, you have documented the actions taken in response to the May 7 Order.
We have reviewed this submittal, and are satisfied that, with respect to Rancho Seco, you have satisfactorily co pleted the actions

Mr. J. J. Mattimce.
prescribed in items (a) through (e) of paragraph (1) of Section IV of the Order, the specified analyses are acceptable, and the specified implementing precedures are appropriate.
The bases for these conclusions are set forth in the enclosed Safety Evaluation.
As noted on page 13 of the Safety Evaluation, you will be required to conduct a tast during pcwer operation to demonstrate operator capability to assume manual control of the Auxiliary Feedwater System independent of the Inte-grated Ccntrol System.
Appropriate Technical Specifications for Limiting Conditions for Operation and for surveillance raquirements should be developed as soon as practicable and provided to the staff within seven days with regard to the design and procedural changes which have been completed in compliance with the provisions of the May 7,1979 Commission Order.
The revised Technical Spacifications should cover:
(1) Addition of flow indication to the Auxiliary Feedwater System; (2) Addition of the Anticipatory Reactor Trips; and (3) Changes in set points for high pressure reactor trip and p0RV actuation.
Slithin 30 days of receipt of this letter, you should provide us with your schedule for completion of the icng tem acdifications described in Section II of the May 7 Order, and you should submit for staff review the model used in the analysis for potential small breaks referenced in your letter of May 14, 1979.
My finding of satisfactory compliance with the requirements of items (a) thrcugh (e) of paragraph (1) of Section IV of the Order will permit resumption of operation in accordance with the tems of the Commission's Order; it in no way affects your duty to continue in effect all of the above provisions of the Order pending your submission and approval by the Ccamission of the Technical Specifi-cation changes necessary for each of the required modifications.
Sincerely, f

ORDER Sy a confirmatory Order dated May 7, 1979 the Commission
([)
directed that the Rancho Seco f acility, then in a shutdown condition, should remain shut down until certain actions speci-fied in the Order were satisfactorily completed, as confirmed by the Director, Office of Nuclear Reactor Regulation, The Order also directed the licensee to acccmplish as promptly as practica-ble the long-term modifications set forth in Section II of the Order.
The Order stated further:
Within twenty (20) days of the date.of this Order, the licensee or any person whose interest may be affected by this Order may request a hearing with respect to this Order.
Any such request shall not stay the immediate effectiveness of this Order.
Requests for a hearing have been received from Friends of the Earth and from members of the Scard of Directors of the Sacramento Municipal Utility District.
}
The Commission hereby directs that the Chairman of the Atomic Safety and Licensing Board Panel shall, pur,suant to t
f C ff {
10 CFR 2.10 5 (e), select a board to determine wha:har the requesters
()
=cet the requisite personal interest test and to conduct any hea2-ing which may be required.
The subjects to be considered at the hearing chall include:
1.
Whether the actions required by subparagraphs (a) through (e) of Section IV of the Order are necessary and suffi-cient to provide reasonable assurance that the facility will respond safely to feedwater transients, pending cumpletion of the long-term modifications set forth in Section II.
A contention challenging the correctness of the NRC staff's cenclusion that the actions described in subparagraphs (a) through (e) have been com-pleted satisfactorily will be considered to be wieb4n the scope of the hearing.
However, the filing of such a contention shall not of itself stay operatior of the plant.
O.
2.
Whether the licensee should be required to accomplish, as prcaptly as practicable, the long-term modifications set forth in Section II of the Order.
3.
Whether these long-term modifications are sufficient to provide continued reasonable assurance that the facility will respond safely to feedwater transients.
Resumed operation of the Rancho Seco facility on terms con-sistent with the order of May 7, 1979, is not stayed by the pen-dency of these proceedings.
Contrary to the contention of the Friends of the Earth in their filing of June 8, 1979, the tran-scripts of the Commission proceedings of April 25 and 27 reflect no Commission intent that hearings necessarily precede restart J
of the f acility.
Nor is such a requirement compelled by law or by the f actual circumstances before us.
Mere speculation that the hearing might develop facts indicating the nee or further e $1B
enforcement action decs
.ct suffice to warrant a prohibition cn ra-O start of the facility.
In tho. event that a need for further enforce-ment action beccmes apparent, either in the course of the hearing or at any other time, apprcpriate action can be taken at that time.
NRC staff has now determined that the actions set forth in sub-paragraphs (a) through (e) have been ccmpleted satisfactorily, and it shali provide the Commission with an informational briefing as to the basis for its conclusions prior to permitting restart of the facility.
That briefing will be open to the public'.
In receiving this briefing, the Commissicn will in no manner prejudge the merits of the adjudicatory hearing authorized by this Order.
Any adjudi-catory determination by the Commission that may arise from that hear-ing will be based solely on the record developed in thau proceeding.-
Q It is so ORDERED.

{ecretaryofjtheCommission o
Dated at Washington, D.C.,
this 21st day of June, 1979.
_ / The decision of the Licensing Board will be made on the basis of the record developed before it.
Accordingly, purnuant to our rules, statements made by a.ny person in the course of the staff's informa-tional briefing for the Commission may not be " pleaded, cited, or relied upon" in the adjudicatory proceedings before the Licensing Board, or in subsequent appellate proceedings before the Appeal Board.
If and when Commission review of that adjudi-cation takes place, any party wishing to plead, cite, or rely on the transcript of the informational briefing will be at liberty to do so.
{}
To that extent, owing to the unusual f actual circumstances present here, we' waive the prohibition contained in 10 CFR 9.103, in accor-dance with the provision of that rule authoriring such waiver by the Commission.
