HUMBOLDT BAY UNIT NO. 3 N DATE: July'17 thru July 20, 1989 x
LOCATION:. Humboldt Bay Plant, Eureka, California PURPOSE: TO VISIT AND PARTICIPATE IN NRC INSPECTION OF THE FACILITY BACKGROUND: PG&E's Humboldt Bay Power Plant is located four miles southwest of.EureR in the King Salmon area of Humboldt Bay. The plemt currently employs seventy-five people.
The Humboldt Bay Power Plant has two operating units which are fueled by natural gas or fuel. oil.. These units can generate'a .
total of 105,000 kilowatts of electricity for PG&E customers. i Two mobile gas turbine generators, each with a capacity to <
produce 15,000- kilowatts, are also located at the plant to assist in meeting peakfsystem demand. In addition, the plant includes a nuclear unit (Unit 3) which has been shut down since 1976. Unit 3 is now in SAFSTOR with fuel storage on site, awaiting final decommissioning in the future.
The nuclear unit at Humboldt Bay began operating in August 1963 and ran for the next 13 years. It was a small unit with a capacity of 65,000 kilowatts electric.
The nuclear reactor was taken out of service in July 1976 for routine refueling and to complete studies and modifications to meet new standards. The new regulations that were imposed after 1976 greatly increased the cost to put the reactor back in. service. PG&E concluded that buying replacement power would ;I cost less than restarting the unit, and decided to decommission
- i t.
OBSERVATIONS: The nuclear fuel has been removed from the reactor and placed in the spent fuel storage pool. The storage pool is a concrete j pool 26 feet deep lined with stainless steel. Leakage from )
the pool, and ground water seepage is collected in the liner {
gap and processed in the plant's radioactive waste processing system,. The liner' gap level is maintained low, so that leakage will be inward from both sides. Total leakage is approximately l 1-1/2 to 2 gallons per day. In addition, ground water seepage {
of approximately 100 gallons of water per day is collected in ]
the caisson at the bottom of the reactor and is also processed in the plant radioactive waste system.

. The reactor and plant piping systems have been drained. Most of the low-level waste has been shipped to licensed radioactive waste disposal facilities. Slightly contaminated waste such as coveralls and gloves are packaged and shipped'to ifcensed radioactive waste disposal facilities during the SAFSTOR period.
Approximately a dozen 55-gallon drums of.LLW are in storage, some stored since 1984.. Several steel boxes of waste are also in storage.-
In addition,LLLWM staff participated in the plant inspection with the Region V Inspector. The inspection areas which we participated in addressed: quality assurance; training;, fire protection; and radiation protection.- In all of these areas some concerns were noted and the regional inspector discussed these on several occasions and on his closing exit interview with plant officials. Specific concerns addressed items such as: (1) records recording in permanent ink; (2) additional training for fire protection engineer; (3)~ storage of combustible materials'in designated cabinets; (4) maintenance of fire protection equipm6nt and (5) proper marking of high radiation areas. Most of the concerns raised regarding the
' fire protection' systems were concerns raised regarding Units 1 and 2 but'could impact Unit 3. However, a violation was cited regarding a high radiation area not being properly identified.
Details will be included in the Inspection Report by Michael C1111s, Region V.
