General The plant was shutdown on March 25, 1979, for a scheduled six week refueling outage.

During the first outage week, eight spent fuel assemblies were shipped to General Electric Company's Morris Operation. The licensee plans to examine the peripheral shroud and if there is no indication of further cracking, it will not be changed out this outage.

It will be changed out after the new spent fuel racks are installed late in 1979.

This will permit unloading the core and reducing personnel exposure during the shroud replacement work.

3.

Plant Operations Review The inspector observed plant outage conditions, irradiated fuel cask loading and shipping, control room manning, and equipment tag out status during a plant tour.

Additionally, the following records were reviewed from February 26 - March 26, 1979, to determine compliance with Technical Specifications and regulations 2311 051 2-

Spent Fuel Pool Activities, Routine l'se of Shippine Packages, and DOT Regulations Because of limited storage space in the spent fuel pool, it was necessary for the licensee to ship cight spent fuel assemblies to the General Electric Company's Morris Operation.

These shipments were made between March 26 and April 3, 1979, in two Nuclear Assurance Casks (NAC-1), Model NFS-4, Certificate of Compliance No. 669S, Revision No. 7, dated August 14, 1978.

The carrier was Tri State Motor Transit.

The fuel selected for shipping had been out of the reactor for fcur or more years with the decay heat generation estimated to be 0.2 KW and thus the cask was shipped dry.

Because of a restriction in one side of the internal cannisters, each shipment contained only one assembly.

During the first cask loading it was determined that the cannister spacers provided by NAC were over an inch too long, preventing the cask head to close.

The fuel assembly was removed, the spacers shortened and the assembly reloaded without further problems.

The second cask loaded, NAC-1C, had been shipped to LACBWR from Nuclear Fuel Services, New York, with the cask full of water.

Ice had formed under the cask lid with some formation also present inside the cannister. After removing the ice and completing the loading, the cask passed both the required quarterly ten minute

"0-ring" test at 200 psig and the cavity pressure test at 80 psig.

The inspector observed the loading and handling of the first two shipments and reviewed the shipping records per-taining to them.

Dose rates and removable contamination were within Department of Transportation (DOT) Regulations as follows:

The inspector determined that DOT requirements for records, labeling and placarding were in the procedure and were followed during the shipping campaign.

No items of noncompliance were identified.
