NRC-Document Control Desk 4
October 2,- 1990 Page 2 In completing the detailed engineering and investigating the 3
' availability.of qualified valves and components to provide these modifications, we have determined that our schedule to1 install these' modifications.during the 1991 Unit.1 refueling. outage 1
cannot 1xt satisfied.
The primary difficulty involves the lead.
time-necessary to-procure the safety-related valves.needed for
- )
these piping changes.
Our detailed engineering and design of these modifications was also delayed by other staff commitments.
We expect to have-the material available to do the Unit 2 modifications in the fall of 1991 as scheduled;'however, this letter is to inform you that we are rescheduling these.
i modifications for Point Beach Unit 1 to'the spring 1992 refueling outage.
Please contact us if you have any' questions.concerning this
- 1 change to our proposed schedule or regarding our. proposed modifications as discussed in the referenced letters.
Very truly yours, 47^f.
