SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR R_E_GULATION RELATED T0_ AMENDMENT NOS. 58 AND 57 T_0 FACILITY OPERATING LICENSE NOS. DPR-32 AND DPR-37 VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION,_ UNIT _NOS. 1 AND 2 DOCKET NOS. 50-280 AND 50-281 htroduction By letter dated August 31, 1979, the Virginia Electric and Power Company (the licensee) requested a change to License Condition 3.G.2.b for the Surry Station steam generator repair program.
The current license condition requires the use of temporary containment and ventilation systems whenever cutting and grinding operations involving components with removable radioactive contamination > 2200 DPM/100 cm are being performed. The change requested would allow the Health Physics Coordinator to determine the need for these systems on a case-by-case basis.
Discussion and Evaluation The purpose of the original license was to protect the workers and the environment from airborne contaminants released as a result of cutting and grinding operations.
The installation of temporary containment systems can, however, result in a higher occupational radiation exposure to personnel when compared to direct operations without the use of the temporary conta inments. This can occur because the radiation exposures received by personnel installing and removing the temporary contain-ments may exceed the exposures caused by the spread of radioactive contamination, especially for operations involving low contamina-tion level components in relatively high direct radiation fields.
In addition, samples taken during cutting operations have shown that airborne activity generated tended to be localized to the extent that only those workers performing the operation would be exposed to the contaminants. Adequate protection could be provided by use of respiratory equipment.
This technique would allow for protection from airborne contamination while subsequently reducing exposures caused by the installation of temporary systems.
The proposed change will provide further assurance that occupational-expostres will be maintained As low As Reasonably Achievable (ALARA).

2-We have reviewed the licensee's submittal and the basis for the proposed c ha nge.
In addition, we have discussed the subnittal with the licensee and OIE inspectors during site visits. Based on our review and discussions, we conclude that the licensee's proposal is in keeping with the ALARA principle and is acceptable.
Environmental Consideration We have determined that the amendments do not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendments involve an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR 51.5(d)(4), that an environmental impact statement or negative declaration and environ-mental impact appraisal need not be prepared in connection with the issuance of these amendments.
Conclusion We have concluded, based on the considerations discussed above, that:
(1) because the amendments do not involve a significant increase in the probability or consequences of accidents previously considered and do not involve a significant decrease in a safety margin, the amendments do not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be conducted in compliance with the Commission's regulations and the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
