Attachment to SMQ-Oll-99 May 4,1999 Page 4 of 5 TROJAN NUCLEAR PLANT SCHEDULE OF ACTIVITIES During the first quarter of 1999, Transition Period activities continued to follow the schedule as updated by Revision 6 of the Trojan Decommissioning Plan.

The Independent Spent Fuel Storage Installation (ISFSI) project continues with fabrication, testing, and training activities. Fabrication of PWR baskets commenced. Delivery of Concrete Cask line s and fabrication of Concrete Casks continues. Pre-operational testing activities commenced and were observed by the NRC. The NRC issued a license to operate the ISFSI.

Fuel loading is expected to start in early 1999 and complete in early 2000.

The Reactor Vessel and Internals Removal (RVAIR) project continues on schedule. Cutting operations to sever piping connections to the reactor were completed. Plates were welded over pipe and instrument penetration openings. Heavy lifting equipment was assembled inside and outside of the Containment Building and successfully load tested. Two inch thick and five inch thick shielding was attached to the reactor vessel. The reactor vessel was raised and lowered to facilitate installation of the shielding. Fabrication continued on the support steel and cradle assembly that will hold the reactor vessel during transport. Fabrication and delivery ofimpact limiter segments continues. The project is expected to be completed during the third quarter of 1999.

Removal of components in the Auxiliary and Fuel Buildings continues as part of ongoing decommissioning activities. Surface remediation activities to remove contamination from concrete surfaces continued in the Containment and Electrical Penetration Area. Cleaning of embedded piping in the Auxiliary and Fuel Buildings continues.
