In an order entered on July 14, 1981, the Atomic Safety and. Licensing-Board (Bbard) directed Pacific Gas and Electric Company (Licensee) to subInit a written statement setting # orth its intentions recarding plant modifications necessvy to bring Humboldt Bay Power Plant, Unit 3, into compliance with current NRC requirements and, if it wished to retain the operating authority j
provided in Facility Operating Li, cense No. DPR-7, a proposed schedule for ecmpleting such plant modifications.
In response thereto, on August 13, 1981, Licensee filed an affidavit executed by its Senior Vice President for l
Facilities Development.
i According to Licensee, additional studies are necessary to evaluate various alternatives for the plant. These studies include updating Licensee's analysis of those actions which must be taken in order to resume power operation as well as various decommissioning options. Licensee has already embarked upon such a program which shocid be completed by December 15, 1981.

MEMORANDUM AND ORDER In an order entered on July 14, 1981, the Atomic Safety and. Licensing' Board (Board) directed Pacific Gas and Electric Company (Licensee) to sub'mit a written statement setting forth its intentions regarding plant modifications necessvy to bring Humboldt Bay Power Pltnt, Unit 3, into compliance with current NRC requirement's and, if it wished to retain the operating authority.
provided in Facility Operating Li, cense No. DPR-7, a proposed schedule for completing such plant modifications.
In response thereto, cn August 13, 1931, Licensee filed an affidavit executed by its Senior Vice President for Facilities Development.
According to Licensee, additional studies are necessary to evaluate various alternatives for the plant. These studies include updating Licensee's analysis of those actions which must be taken in order to resume power operation as well as various dedommissioning options. Licensee has already embarked upon such a program which should be completed by December 15, 1981.

1ssues guidance on those requirements.
Licensee's response concludes with the statement that it is extremely reluctant to abandon a proven source of generation located in a relatively isolated area within its system and with the assertion that:
'"Since the unit, it its present cold shutdown condition,
~
presents no risk to.the health and safety of the public, PGandE believes that there is no compelling reason for this Board to issue an Order to Show Cause why the operating authority for Humboldt Bay Unit No. 3 should be revoked..
We are convinced that it is beneficial to maintain the plant in an operational status pending a decision.on NRC backfit requirements and an assessment of their effect on the.
economics of returning the Unit to operation."
Before taking further action in this proceeding, the Board would like to have the views of the NRC Staff on Licensee's assertion that the Humboldt Bay nuclear plant in'its present cold shutdown conditien, presents _no risk to the health and safety of the public. Specifically, the Staff is directed I.
to provide answers to the following Board questiens:
1.
What regulatory requirements apply to'a plant in cold shutdown mode.
2, Are applicable regulatory requirements currently being met by
' Licensee?
3.
Has the Staff given consideration to the question of whether the exceptionally long shutdown of Humboldt Bay Unit No. 3 might give rise to the pctential f,or significant safety l
problems? What unusual problems might arise?
l 4.
Has there been any evidence whatsoever of seismic effects within the exclusion area? If so, please describe.
