the first semi-eansal operettag report for the period May 1969 thru tesseber 1969. W ". . *

, The operations 4setag this first reporting period for Dait No.1 of ths Oyster Creek Reclear Generating Staties of the Jersey Central power and Light Campany esasisted primarily of events related to the step-wise approach to semanarcial operaties at full license power. A certes of thirty- '

,  ; two start-wp tests were sempleted at warious power levels, seecluded wit.h the ,

ene hundred hour full power deseastration l which was temp 1sted as December 12, 1969, ct 11:00 p.m. i

! Initial criticality wea achieved with the head off the reactor vessel at 2:17 p.m.

on May 3, 1969. With the complettee of low power testing, the insta11atten of hot vibretten testing sensors, and the instal-l latte of moisture separator and stem dryer, the reacter vassal heed was installed j om June 19, 1%9. One quarter power was I. achieved on September 22, 1M93 ene half l pmser on September 26, 1969; three-quarter j power en November 19, 1969, and full power

, en December _7, 1969. The turbins generator l 3 was first synchresised to the traaemission l I system on Septeenber 23, 1969.

I I l During the period of ascension to full power several situations developed which required g shutdooms for eerrective- acties or fu:rther

, investigation end easign modification. la general and in chronological order, the felleving itaus were of major concern.

perary draim systam was tastalled (the permanent drain system was scheduled for

f. completion in 1970). Problems were owperi-j- anced with the tuning-up of the mechanteal pressure regulater and an electric pressure
