DESCRIPTION:
Proposed Amendment No. 183 adds an additional condition to Operating License No. DPR-54 which prohibits the movement of new or spent fuel into the Reactor tu11 ding without prior NRC approval.
REASON FOR CHANGES:
lhttAD.it The Sacramento Municipal Utility District (the District) has determined that l
it is in the customer / owners financial interest to discontinue operation of Rancho Seco Nuclear Generating Station. As such, the District has placed the plant in a cold shutdown mode for the purpose of defueling the reactor.
In order to help ensure the continued protection of the health and safety of the public, the District requests a condition be placeo in the License that I
prohibits the movement of new or spent fuel into the Reactor Building subject to NRC approval.
This License condition will establish that potential problems associated with having nuclear fuel in the reactor vessel are not credible.
EVALUATION AND BASIS FOR SAFETY FINDINGS:
This Proposed Amendment places an additional restriction on the activities allowed under the current Operating License for Rancho Seco.
This restriction which prevents the movement of new or spent iuol into the Reactor Building, in effect restricts further power operation of the unit without prior NRC approval. However, the License condition does not prohibit all other activities under the present License, i
Moreover, this Proposed Amenoment will result in an increase in the protection of the public health and safety by placing an additional restriction on the License affecting the power operation of the facility.
The License condition requiring prior NRC approval for movement of fuel into the Reactor Building ensures an added level of safety above the conditions in the current License.
i NO SIGNIFICANT HAZARDS CONCIDERATION The District has reviewed this Proposed Amendment against each of the criteria of 10 CFR 50.92 and concluded that:
It does not involve a significant increase in the probability or consequences of an accident previously evaluated since it imposes additional operational restrictions (i.e., movement of fuel into the Reactor Building without NRC approval) while not modifying the present plant protection systems and controls.

NO $1GNIFICANT HAZARDS CONSIDERATION (Continued)
It does not create the possibility of a new or different kind of accident from any accident previously evaluated since it does not modify the facility or permit activities of a different kind than those that are presently allowed.
1 It does not involve a significant reduction in a margin of safety since it i
allows no nov activities, keeps present controls and restrictions in place, and adds additional conservative restrictions on plant operations.
l Therefore, the District concludes that Proposed Amendment 183 involves no significant hazards consideration.
