t M

I f
jr There are five-license conditions that relate to criticality safety.
Although Rocketdyne did not specifically request that these conditions be deleted, the q
staff has.~ decided to address these conditions.
Conditions 13, 16, and 17 7
.should be deleted from the license.
Condition 15 relates to record retention N
and should therefore remain in the license.
Condition 14 should be revised to remove the portion relating to criticality safety training.
Condition 14 shall read as follows.
14.- All personnel, prior to unsupervised work with special nuclear materials,'shall receive formal training in radiation safety.
The.
j effectiveness _of the training program shall be measured by written examination.
LAdditionally, the staff recommends that Condii, ions 60, 70, 8C, and 11 also be.
.ic Ldeleted.
These conditions pertained to the TRUMP-$ program.. Remaining.
.(
' conditions relate to radiation protection, release criteria, and l
decommissioning, Rocketdyne.had no objection to the deletion of the conditions.
t
' Conclusion / Recommendation ~

4 The staff has_ determined that Ro'cketdyne no longer needs to maintain the
,. criticality control requirements contained in the license.
Therefore, the t
' : staff rAcommends that Condition 9 be. revised to delete Chapter 4 from the
?1icense;l Conditions 6C, 7C, 80, 11, 13, 36, and 17.be-deleted; and Condition 14 i
