Dear Mr. Skovholt:

This letter is to confirm Mr. Harlan K. Hoyt's telephone conversation with you on September 18, 1972, concerning the torus vacuum breakers on Quad-Cities Units 1 and 2. .

The lever arm modification, which will improve the torus N, vacuum breaker operation, is in progress on Unit 2 at the present

  • time. Unit 2 is currently out of service for repairs to the jet pumps. Unit 2 will not be returned to service until the vacuum breaker lever arm modification is complete.

Current plans for Quad-Cities Unit 1 call for the lever -

arm modification to be installed between October 8 and October 15, 1972. This schedule is dictated by the return to service of Quad-Cities Unit 2 as mentioned above and Joliet Unit 8. Joliet Unit 8, a 600 Mw fossil fueled unit, suffered the loss of its main trans-former last week. Should any change in these plans be required, we will contact you immediately. .
