Washington, DC 20059 In the Matter of General Electric Co.
(Vallecitos Nuclear Center - General Electric Test Reactor)
Operating License No. TR-1 Docket No. 50-70
Dear Administrative Judges:
Pursuant to the tems of the stipulation executed by counsel for the parties to this proceeding dated May 7,1981, the Staff submits the following list of exhibits which it will offer into evidence in this proceeding.
The first four documents collectively comprise the Staff's Safety Evaluation (SE) for this proceeding as well as Staff Exhibit 1, although for convenience they have been separated into four subparts of the same exhibit in recognition of the fact that the evaluation was sent out in fcur installments. The four sections of the SE were recently sent to the Board and parties again as enclosures with the Staff's prefiled proposed written testimony for this proceeding on !!ay 1,1981. These documents shall be offered as follows:
Exhibit Number Description Staff EL. 1A Geosciences Branch Safety En.luation Report Input dated September 6,1979, originally sent as a status report as an enclosure to a Staff letter to GE dated September 27, 1979.
Note: this proposed exhibit is the same document that was sent to the Board and parties on May 1, 1981, and has the conclusions deleted that were originally included in the Geosciences Branch status report which was sent to GE in 1979. The 1979 status report, with 8105140 M G
conclusions deleted, was incorporated into the Staff's SE (See May 23, 1980 SE (proposed Staff Ex.18), page 4).
Staff Ex. 1 B SE sent as enclosure to Staff letter to GE dated liay 23, 1980.
Staff Ex. 1 C SE sent as enclosure to Staff letter to GE dated October 27, 1980.
Staff Ex. 1 D SE sent as enclosure to Staff letter to GE dated January 15, 1981.
Staff Ex. 2 Letter from M. Plesset of the Advisory Committee on Reactor Safeguards to Chaiman Ahearne dated November 12, 1980, a copy of which is enclosed.
The prefiled written proposed testimony which was sent to the Board and parties on May 1,1981, will be individually sponsored.
It is the. Staff's present intention to offer the prefiled testimony to be received into evidence and bound into the record as though read, rather than treat the pieces of testimony as exhibits.
Sincerely.

REPORT ON THE RESTART OF THE GENERAL ELECTRIC TEST REACTOR
Dear Dr. Ahearne:
During its 247th meeting, November 6-8, 1980, the ACRS reviewed a request by.
the General Electric Company to restart and operate the General Electric Test Reactor (GETR) at pos.er levels up to its rated power of 50 MWt.
A tour of the facility was made by members and consultants in connection with November 14, 1979 and June 16 and 17, 1980 meetings of the Subcomittee and the matter was further considered at a Subcomittee meeting on November 4,1980.
During its review, the Comittee had the benefit of discussions with representatives and consultants of the Licensee and the Nuclear Regulatory Comission (NRC) Staff.
The Committee also had the benefit of the documents listed.
The GETR, which was granted an operating license in January,1959, was shut down on October 24, 1977 in accordance with a Comission order.
This order followed discovery of a fault near the location of GETR and brought into question the plant's capability to withstand the effects of an earthquake that might occur on or near the newly discovered fault.
After extensive study of the geology and seismology of the site, and of the ragion nearby, the NRC Staff concluded that in order to operate the plant it must be shown that it can sustain a ground level acceleration, unaccompanied by surface offset under the foundation, of 0.75g and that it must also be shown to be capable of withstanding a ground level acceleration of 0.69 simultaneous with a surface displacement of one meter of reverse-oblique net slip along a fault plane having a dip between 10 and 45 degrees.
The ACRS agrees that these criteria are sufficiently conservative.
In order to achieve compliance with these criteria, the General Electric Company has proposed some plant modifications and has performed as extensive analytical investigation to demonstrate that the modified plant can survive 1
an earthquake having the characteristics of the Staff's criteria.
The NRC Staff has reviewed and approved the analyses and the modifications.
The ACRS agrees that the plant as modified should be able to withstand the postulated seismic events with no significant release of radicactive material.
D(A P E o t"
?o L.L L % Q
Moe.crable Jchn F. Ahearne 2-November 12, 19EC The.IRC Staff has yet to resolve one issue cf seismic leading which is decen-dent on the characteristics of the soil beneath the GE R fcundation.
Tne Staff and the Licensee are both confident, however, tha: this issue can be resolved after further calculation by the Licensee and review by One Staff.
The ACRS recommends that this issue be resolved to the satisfaction of tne Staff.
Subject to resolution of the above issue, the ACRS believes that the GETR, as modified, can be restarted and operated at its rated sc.eer level cf 50 C:,
without undue risk to public health and safety.
Si ncerely,
Y ed
