SUBJECT:

REQUEST FOR PUBLICATION IN BIWEEKLY FR NOTICE - NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY

OPERATING LICENSE, PROPOSED NO SIGNIFICANT HAZARDS

CONSIDERATION DETERMINATION, AND OPPORTUNITY FOR A

HEARING

Pacific Gas and Electric Co., Docket No. 50-133, Humboldt Bay Power Plant (HBPP), Unit 3 Humboldt County, California Date of amendment request

May 3, 2013 Description of amendment request

The proposed amendment would add License Condition 2.C.5 that approves the License Termination Plan (LTP) and adds a license condition that

establishes the criteria for determining when changes to the LTP require prior NRC approval.

Basis for proposed no significant hazards consideration determination

As required by 10 CFR 50.91(a), the licensee has provided its analysis of the issue of no significant hazards

consideration, which is presented below:

2 (1) Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?

No. The change allows for the approval of the LTP and provides the criteria for when

changes to the LTP require prior NRC approval. This change does not affect possible

initiating events for the decommissioning accident s previously evaluated in the Humboldt Bay Power Plant (HBPP) defueled safety analysis report (DSAR), as updated, Appendix

A, "Implications of Decommissioning Accidents with Potential for Radiological Impacts

to the Environment," or alter the configuration or operation of the facility. Safety limits, limiting safety system settings, and limiting control systems are no longer applicable to HBPP in the permanently defueled mode, and are therefore not relevant.

The proposed change does not affect the boundaries used to evaluate compliance with

liquid or gaseous effluent limits, and has no impact on plant operations. Therefore, the

proposed license amendment does not involve a significant increase in the probability or

consequences of an accident previously evaluated.

(2) Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?

No. The safety analysis for the facility remains accurate as described in the HBPP

DSAR, as updated, Appendix A. There are sections of the LTP that refer to the

decommissioning activities still remaining (e.g. removal of large components, decontamination, etc.). However, these activities are performed in accordance with

approved HBPP work packages/steps and undergo 10 CFR 50.59 screening prior to

initiation. The proposed amendment merely makes mention of these processes and

does not bring about physical changes to the facility. Therefore, the facility conditions

for which the postulated accidents have been evaluated are still valid and no new

accident scenarios, failure mechanisms, or single failures are introduced by this

amendment. The system operating procedures are not affected. Therefore, the

proposed changes will not create the possibility of a new or different kind of accident

from any accident previously evaluated.

(3) Does the change involve a significant reduction in a margin of safety?

No. There are no changes to the design or operation of the facility resulting from this

amendment. The proposed change does not affect the boundaries used to evaluate

compliance with liquid or gaseous effluent limits, and has no impact on plant shutdown

operations. Accordingly, neither the postulated accident assumptions in the DSAR, as

updated, Appendix A, nor the Technical Specifications are affected. Therefore, the

proposed change does not involve a significant reduction in a margin of safety.

3 The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff

proposes to determine that the amendment request involves no significant hazards

consideration.
