NARRATIVE REPORT UNIT 1 Sept. 4th Rx scram at 14:39 due to false high MSR level; scram ' caused by equipment failure of the LS on the MSR; LS was grounded Sept. 4th Startup from above shutdown, #80-46; Rx critical at 20:55, and generator on line at 01:49 on Sept. 5th.; unit -returned to 80% conditions at l

07:00 on Sept. 7th c

_q-Sept. 7th Reduced load in order to perform final rod pattern adjustment from above startup; unit returned to 80% conditions at 12:00 on Sept. 8th

Sept. 12th Redu*ed load in order to perform weekly turbine tests and rod pattern adjustment; unit returned to 80% conditions at 21:30 on Sept. 13th i

Sept. 21st Rx auto scram at 12:53 due to the transferring of RPS channel "B" bus from alt to normal and a l spurtous trip on RPS channel "A"

. Sept. 21st Startup from above shutdown, #80-50; Rx critical at 23:05,- and generator on line at 04:44 on Sept. 22nd; unit returned to 80% conditions at t ;

3 18:45, Sept. 22nd ,

Sept. 23rd Reduced load in order to perform a rod pattern adjustment; unit returned to 80% conditions at 02:45 on Sapt. 24th Sept. 27th Reduced load due to debris 4

stopping up PSW strainers

There was no single ' release of radioactivity or single radiation exposure which accounts for more than 10% of the allowable annual-values during September of 1980.
