EUNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 104 TO FACILITY OPERATING LICENSE NO. DPR-23 CAROLINA POWER AND LIGHT COMPANY H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 DOCKET NO. 50-261
- 1. Introduction By letter dated August 13, 1986, the Carolina Power and Light Company (the licensee) submitted proposed changes to the Technical Specifications (TS) appended to Facility Operating License No. DPR-23 for the H.B. Robinson Steam Electric Plant, Unit No. 2.
The proposed changes would modify the Technical Specifications to delete the limit on the quantity of fissionable material that may be used in the core, or available onsite in fission detectors.
- 2. Discussion Technical Specification 5.3.1.6 limits to 10 grams the quantity of enriched fissionable material which may be used either in the core, or available on the site, in the form of fabricated neutron flux detectors for the purposes of monitoring core neutron flux. The licensee is installing a new excore neutron monitoring system as required by the NRC pursuant to Regulatory Guide 1.97, Revision 3 and for alternate shutdown. Each of the detectors in the new system will contain a small quantity of enriched fissionable material.
The total quantity of fissionable material onsite would exceed that allowed by TS 5.3.1.6.
Section 2.C of the Operating License was amended on July 30, 1980, to permit
-the licensee, pursuant to the Act and 10 CFR 30, 50 and 70, to receive, process and use at anytime any byproduct, source and special nuclear material such as sealed neutron sources for reactor startup, sealed sources for reactor instrumentation and radiation monitoring equipment calibration, and fission detectors in "amounts as required."
Apparently by oversight, TS 5.3.1.6 was not amended to remove the restriction in the number of grams of enriched fissionable material allowed onsite in neutron flux detectors.
- 3. Evaluation The proposed change to TS 5.3.1.6 would delete this section which limits the quantity of enriched fissionable material in neutron flux detectors to 10 grams.
This limit is inconsistent with Section 2.C of the Operating License which authorizes the use of special nuclear material in sealed neutron sources and fission detectors in "amounts as required."
The intent of this section was 8611140290 861027 PDR ADOCK 05000261; P
-2 to allow the use of identified materials in amounts as required for reactor operation. This change does not impact on safeguards control (e.g., Material Control and Accountability or Physical Security) because any increase in the amount of the material would be small. The licensee has programs in place to control and account for special nuclear material (SNM) and existing physical security systems. These safeguards programs will continue to operate effectively with the small increase in SNM quantity. Deletion of TS 5.3.1.6 will make Technical Specification consistent with Operating License Section 2.C. We, therefore, find this deletion acceptable.
Environmental Consideration This amendment involves a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
Conclusion We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
