Miller, Chief Standardization and Special Project Branch Division of Licensing U.S. Nuclear Regulatory Commission s Washington D. C. 20555

Dear Mr. Miller:

Enclosed please find three copies each of a revised Appendix C,

" Fuel Elemen' Cladding Failure - Assessment of Exposure Doses" and Appendix D, "Liract Radiation Dose at the Etcheverry Hall Patio Due to Loss of Pool Water", to the Berkeley Research Reactor Emergency Plan dated July 25, 1977, sent to your office as part of the relicensing procedure of our TRIGA III Reactor, on August 5,1977.

Revisions in Appendix C are based on = ore up-to-date fission product fractional release of 1.5 x 10-5 he old Appendix C applied a fr3c-tional release of fission product of 10-2, The revised Appendix D applies a more nearly realistic but still conservative reactor operation history of 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> continous opera-tion at 1 MW before the cooling water is lost. The old calculations were based on infinite time operation whereas average operation are less than L Edh per week.

If you have any further questions in this regard, please contact Dr. Tek H. Lim at (415)642-5213 or myself at (415) 642-5341.
