Dear Mr. Sirr'ons:
Thank you for your letter in which you expressed concern related to the need for deconmissioninq !!unboldt Bay Power Plant, Unit No. 3.
nn July 2,1976, the Hunboldt Bay Plant was shutdown for replaceaent of sono of the fuel in the core. By Order dated May 21, 1976, the NRC required that before resuning operation, the Pacific Gas and Electric Company (the licensee) complete certain activities. The licensee was required to upgrade as necessary, the seisnic capability of safety-related equipment (e.g. the reactor coolant pressure boundary) to current requirements, and to resolve vore recent seismic concerns having to do with carthquake vulnerability that had arisen since the time an operating license was issued on August 29, 1962.
The licensee has replaced the fuel in the core, undertaken extensive geological investigations, and completed some plant modifications. The future operation of the Hunholdt Day Plant is before a Licensing Board which on February 16, 1982 issued a Menorandum and Order which established a time table for the licensee to decide whether it would resune operation of the plant or decon-nission it.
Before approving resumed operation of the Humboldt Bay Plant the NRC staff would have to be assured that the health and safety of the public is adequately protected with the plant in operation. While the plant is shutdown the NRC staf f nust be satisfied that the health and safety of the public is adequately protected with the plant in the shutdown condition.
Since the time that the Ilunboldt Day Plant was shutdown, the standard inspec-tion (surveillance) progran for a shutdown reactor has been perfomed by the tIRC Regional Office at the !!unboldt Bay Nuclear Power Plant.
This inspec-tion consists of inspections of design changes and r'odifications, activity of the Onsite Review Comittee, QA progran, overall training progran, fire prevention and protection, surveillance of equipment during extended shutdown, security and materiaf accountability, radiation protection program, trans-portation of radioactive materials, and radioactive waste nanagement. Inspec-tions have not revealed any major problems at the plant.

/l,.r, 1 l The consequences and types of accidents possible at the Humboldt Bay Plant are greatly dininished because of the present shutdown condition of the plant. Staff studies show that Ifumboldt Ray fuel has decayed sufficiently that air cooling is adequate to preserve fuel cladding integrity. There-fore, measures to assure core cooling or mitigate loss of coolant consequences are unnecessary. Due to the long period since shutdown, mobile radioactivity has decayed very significantly.
Issues regarding economic inpacts on ratepayers of a decision to deconnission do not lie within the purview of the !!RC, and therefore, cannot be considered by the NRC in requiring decommissioning. However, we can assure you that all safety issues pertinent to an operating reactor will be resolved before the Connission would pemit future operation of the liunboldt Day facility.
With the plant in its present condition the staff considers that the health and safety of the public is adequately protected, and finds no basis to require deconnissioning the plant.
.I hope this infomation will be of use to you.
Sincerely, onci.uisis.%
