Attention: Document Control Desk
Reference:
License R-33, Docket 50-73 Gentlemen:
The Vallecitos Nuclear Center (VNC) requests a change to Section 2.B.(3) of License R-33 which will increase the amount of contained byproduct material permitted for use at the Nuclear Test Reacto. (NTR) from 200 curies to 2,000
(
curies. A full description of the requested change and a safety analysis are included in the attachment to this latter.
If you have any questions concernina this requested change, please contact me at (510) 862-4330. Thank you.
Sincerely,

Pronosed Amendment to License R-33
- 1. Pronosed Chanae The Vallecitos Nuclear Center (VNC) requests that Section 2.B.(3) of License R-33 be modified to read:
.... Licensing of Byproduct Material, (1) to receive, pos ess and use 2,000 curies of either activated solids as contained n but not limited to such items as encapsulating materials, stractural materials and irradiated components or as contained mater als, "
(2) any byproduct....". -
- 11. Eafety Analysis
References:
(1) " Environmental Impact Appraisal, General Elec tric Nuclear Test Reactor"; August 3,1979.
(2) " General Electric Nuclear Test Reactor Safet; Analysis Report", NED0-12727; April,1981.
(3) Safety Evaluation Report, NUREG-1069; Septemter, 1984.
(4) " Calculated Dose Rate at 3 Feet From an NTR Fuel Element, Revision 1"; August 29, 1990.
The bases for this request are: (1) the material is not in a raadily dispersible form; and (7) the crushing of the material could not result in consequences acre severe than those already postulated for the worst accident scer ario for the NTR (i.e., the crushing of the _
core).
The EIA for the NTR submitted on August 3, 1079, notes that the Commission has previously determined that accidents including tle largest core damage and fission product release considered poss ible result in doces of only a fraction of 10 CFR Part 100 guideline; and are considered negligible with respect to the environment (Memo,
" Environmental Considerations Regarding the Licensing of Research Reactors and Critical Facilities", C. R. Muller to 0. skovholt:
January 23,1974).
The SAR for the reactor (Ref. 2) as rc.odified (VNC's June 19. 1984, response to Question 24 of the NRC's letter of June 1, 198 demonstrates thtt the crushing of the entire NTR core does not result in any significant release of fission producte. This is confirmed in Section 1/. 7 of the SER (Ref. 3).

jp The most recent calculations of the fission product inventorv, including volatiles, which were made to demonstrate that th NTR fuel is-self-protecting (Ref. 4) show a core content of 378,000 curies at shutdown and 56,220 curies after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
-The requested material will be in nonreadily dispersible form as is now required by License R-33. These materials are taken to the NTR for neutron radiography. By the nature of the neutron radiography process, the only credible accident would be :ome sort of crushing during handling, III Conclusion If the crushing of the reactor core with its large inventory of fission products will not result in the release of significant quantities of radioactive material to unrestricted areas, any similar scenario withithe requested 2,000 Ci-in the forms permitted by-License R-33 cannot result in significant releases.
