SUBJECT:
REVIEW OF LICENSE Af!ENDMENT APPLICATION DATED SEPTEMBER 11, 1978 AND SUPPLEMENTS DATED NOVEMBER 3, AND DECEI1BER 22,1978 I Background Combustion Engineering (CE) by application dated September 11, 1978 and supplements dated t!ovember 3,1978 and December 22, 1978, requests their SM4 License No.1067 be updated to reflect changes and additions made to the ventilation system and associated monitoring.
The application replaces a previous one dated June 4,1976.
II Discussion A.
Environmental Effects The ventilation in the fuel manufacturing building (Building 17) was provided by three separate exhaust systems:
for (1) the powder preparation and pellet press stations, (2) the recycle and grinder systems, and (3) the furnace hydrogen burn off system. A fourth one has been added to provide ventilation for the annex to the manufacturing area, which includes a new UO2 micronizer operation and equipment relocated from the hydrogen burn off and the recycle grinder ventilation systems. The new exhaust system provides additional capacity to the manufacturing building ventilation system.
The new ventilation system provides 6000 CFil capacity which is approximately 30% more than previously available for the hydrogen burn off and the recycle and grinder systems.
Corrective action is taken whenever the gaseous effluent in any of the four exhaust systens exceeds 25% of the maximum allowable unrestricted area con-centrations as listed in 10 CFR Part 20, Appendix B, Table II, for five consecutive days in any one month.
In addition, a license condition shall be added that requires the licensee to set an action level that would limit the total radioactivity released from all four exhaust systems to 2 pCi/ week.
This level (under very conservative meteorological conditions) corresponds to less than 20 mrem / year to the nearest resident.
Even under the conserva-tive assumed meteorological conditions, the maximum dose to the nearest resident meets the EPA standard (maximum of 25 mrem / year), which becomes effective December 1979.

- B.
Safety considerations fb changes in either the radiological or nuclear criticality safety controls at CE have been proposed in the application. Therefore, no significant change in the safety of the operation should result.
C.
General The amendment application was discussed on October 17,1978 with W. W. Kinney, Region I (IE) Project Inspector, and with P. E. Clemons, Region I (IE) Radiation Specialist, for the CE facility.
They saw no safety or environmental problem with the authorization of the changes made to the ventilation system and associated monitoring.
III Conclusion The addition of the new ventilation system and the corrective action level specified, together with the reconmended license condition, for the gaseous effluent control are adequate to protect the health and safety of the operating personnel, the public and the environment.
Issuance of the license amendment is reconmended subject to the license cor.dition that the corrective action level for gaseous effluent control includes a limit of 2 uCi/ week for the total facility release.
