Dear Mr. Moscicy:

H. B. ROBINSON UNIT NO. 2 LICENSE DPR-23 RO:II:50-261 FAULTY OVERCURRENI TRIP DEIAY DEVICE IN CIRCUIT BREAKERS FOR ENGINEERED SATETY SYSTEMS I

In our letter to you of April 26, 1973, we stated that the over-current trip devices would be installed during this current outage. At this time the vendor has informed us that these trip devices will not be availabic for approximately two months. This schedule will not allow us

'[ i to complete this modification during this outage. We will continue our monthly surveillence of the affected equipment, and the overcurrent devices will be changed out as soon as they are availabic. In addition, we are inspecting each of the overcurrent trip devices during this outage to insure that the installed devices are not cracked.

Very truly yours, b

E. E. Uticy -
