Docket No. 70-7001 Monthly Update on Progress of Seismic Upgrades to Buildings C-331 and C-335 i
Dear Mr. Pierson:
In accordance with USEC's commitments in our April 15,1998 letter (Reference 1), the purpose of this letter is to provide the monthly update on the progress of the installation of the seismic upgrade modifications to Buildings C-331 and C-335.
Issue 36 of DOE /ORO-2026, " Plan for Achieving Compliance With NRC Regulations at the Paducah Gaseous Diffusion Plant"(the Compliance Plan) requires that the modifications to increase the seismic capacity of Buildings C-331 and C-335 be completed by June 30,1999. As identified in our previous monthly status reports (Reference 2), USEC had anticipated that an additional 12 months would be required to complete the seismic upgrades to account for unanticipated construction difficulties and reduced worker productivity due to high temperatures. A Certificate Amendment Request (CAR) was submitted on January 12,1999 (Reference 3) to request NRC review and approval of a change in the schedule for completing these upgrades to June 30,2000. On June 30,1999, NRC issued a Notice of Enforcement Discretion to allow USEC to continue plant operations until the NRC can issue the amended Certificate of Compliance for the this CAR.
During recent discussions with the NRC staff, USEC identified that additional time may be required b
to complete this project due to delays in relocating fissile /potentially fissile materials stored in DOE Material Storage Areas (DMSAs) in areas of the two buildings in which steel removal e.nd/or installation must occur. DOE questions about the handling of fissile /potentially fissile material in the DMSA's from a nuclear criticality safety standpoint have delayed the movement of these h
materials from areas affecting construction. There are 46 work locations which remain inside fI DMSAs from which these materials must be relocated prior to beginning construction activities.
USEC is in the process of preparing a CAR to request an additional extension to September 30, i
2000. This request will be submitted to DOE by October 1,1999 for their concurrence. The CAR will then be submitted to NRC within oneyp3; of obtaining DOE concurrence, j

During~ August,47 locations were completed. A total of 357 out of 723 locations have been L
completed. An average completion rate of 29 locations per month is necessary to support the proposed September 30,2000, completion date. However, the current monthly completion targets are higher than the required average because some locations scheduled to be worked near the end of the project are expected to be more difficult to complete. The goal for September is 50 locations.
- USEC has authorized the construction contractor to add two additional crews (21 additional workers) to assist in meeting the proposed schedule. A revised schedule, showing the proposed new completion date of September 30,2000 will be included in the next monthly status report.
The enclosure to this letter provides a list of new commitments contained in this submittal. Should you have any questions related to this subject, please contact me at (301) 564-3250.
