Pressure and temperaturd were maintained was raised to 340*F. On 2/22/84 pm, primary loop temperature RCS piping snubbers. During inspection minor interference was identified on above 350*F) was expected for 2/24/84They appear to be not significant. Mode 3 (R on lower end turns of motor.During this period RCS pump 1-3 was out of service repaired at site. Preliminary analysis indicates that motor can be Hot System testing is planned for week of 2/26/84 Information is current as of 2/24/84 pm.

SUBJECT:

DAILY HIGHLIGHT Diablo Canyon Units 1 & 2 The reactor vessel head is installed 'and the first pass of the bolt tensioning is complete. The only problem with installation of reactor intervals was with two control rod clusters that were slightly bowed, did not pass the drag test and had to be replaced. After-the second pass of bolt' tensioning is done and the reactor coolant pumps operable, the plant will be ready for cold testing.

All contruction activities inside containment have been halted until fuel loading has been completed and the vessel head put into place.

Asof0700(PST)onNovember 17, 1983, 50 fuel element assemblies had been loaded. By 0700 (PST) on November 18, 1983, a total of 77 fuel element assemblies have been loaded. Approximately 119 fuel element assemblies remain to be loaded. There has been a delay due to the air drive motor on the transfer trolley seizing. The motor s is being replaced and fuel load restart is anticipated to begin at '
