.n MEMORANDUM AND ORDER ST\\.6 i
j In an order entered on July 14, 1981, the Atomic Safety and-Licensing i
Scard (Sbard) directed Pacific Gas and Electric Company (Licensee) to submit a writ +.en statement setting forth its intentions regarding plant modificatiens neceswy to bring Humboldt Bay Power Plant, Unit 3, into ccmpliance with current NRC requirements and, if it wished to retain the operating authority provided in Facility Operating Li, cense No. DPR-7, a proposed schedule for ccmpleting such plant modificaticns.
In response theretc, en August 13, 1981, 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 decomissioning options. Licensee has aiready embarked upon such a program which should be completed by December 15, 1981.

+c 2-However, an additional six months will be required, to reassess the costs associated with various alternatives being evaiuated, after the Commission determines backfit require'ments' for older plants such as Humboldt and n.
~~~
i.ssues 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 sys' tem anc with the Essertion 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 oper'ating 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 cf 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 to provide answers to the following Board questions:
1.
What regulatory requirements apply to a plant in cold shutdown mode.
2.
Are applicable regulatory requirements currently ~ being met by Licensce?
3.
Has the Staff given consideratior, to the question of whether the exceptionally long shutdown of Humboldt Bay Unit No. 3 might give rise to the potential for significant safety problems? What unusual problems might arise?
4.
Has there aeen any evidence whatsoever of seismic effects within the exclusion area? If so, please describe.
t
1 e,
3 5.
What physical security measures are currently in force? What.
was date and nature of last change to physical cecurity procedures?
What changes are planned between now and end of CY 19827 (Assume no change in operational status).
^
6.
What surveillance is being routinely performed by I&E? What was date andmature7f-hst ch'ange-in Toutine surveillence? What changes are planned between now and end of CY 19S27 What.non-routine surveillance has been performed? What were the results of surveillance efforts in 1980, 1981?
(Assume no change in operational status) 7.
What is status of facility, including components and systems that are routinely operated; and including location and conditions of storage of all new, partially used, and spent fuel? What is currently being done.to maintain fuel integrity and assure its safety with respect to security, criticality and thermal stability?
8.
Describe physical and preventive maintenance being performed to assure continued integrity of safety related components. What is size, makeup (by discipline) and duty cycle of standby crew?
What will be required to return facility to operational readiness?
Is there known deterioration of any components such that replacement is contemplated in order to retain adequate standby conditions -
in order to_ achieve operational readiness? Has state of technology advanced to such an extent-that any significant ccmponents on instrumentation and control systems will need to be modified to t
achieve operational readiness?
ORDER It is this 20th day of October 1951 i
ORDERED That within thirty (30) days of the date of service cf this Order, the NRC staff shall file written reshenses te the Board's questiens set for:5 above. Other parties may file their. comments regarding the questions or th'e Staff's responses thereto within fifteen (15 days) efter service of the Staff's responses.
