Division of Licensing U.S.fluclear Regulatory Commission Washingten, D.C.
20555 Docket 50-142 g
Dear Mr. Bernard:
This is to advise you that UCLA recently transferred off-site a quantity of unirradiated U-235 reactor fuel sufficient te reduce the total jnventory of U-235 at the UCLA facility to 4.92 kilograms - 3.53 kilor, rams irra6hted, and 1.39 kilograms uni rra dia ted.
The off-site transfer was completed on July 21, 1982.
I have enclosed copies of the fuel transfer forms for this shipment.
1 As you know, UCLA had br ining for sone time to make this fuel transfer in order to remove an unnecessary constraint on future facility operations..In connection with this, in January 1981, the Commission infarned UCLA that in order for UCLA to remain exempt from the Commission's upgraced safiguards regulations which became effective in flovember 1979, UCLA would sither have to naintain 'the. self-protecting conditions for the "in-core" fuel (100 Rem /hr at 3 feel, unshielded) or reduce its inventory of " fresh" fuel in storage [J. R. Mi7ler letter to W.'F. Wegst, January 12, 1981].
In response, UCLA informed the Commission that reactor operations were being scheduled to maintain the self-protecting conditions for the in-core fuel but that UCLA was also planning to reduce its Lnirradiated fuel inventory [W. F. Wegst letter
}
to J. R. Miller, January 29,1981].
UCLA has determined that under normai reactor operating conditions the self-protection criteria are generally sat?sfied. However, now that. the total inventory of reactor fuel at the facility has been reduced to below 5 kilograms, UCLA need not maintain the self-protecting conditiores to remain exempt from the safeguards requirements contained in 10 CFR 73.60.
As a result UCLA need not be concerned with the possibility that the reactor may have to be shut down for an extended period of time _ at some time in the future.
Sincerely, 1
tti h/
