Dear Mr. O'Reillyt f
I In accordance with the requirements of Section 6.12.2.a of F
the Technical Specifications of Facility Op3 rating License No. DPR-26, the following report is submitted.
v I
Periodic surveillance test PT-M2, " Reactor Coolant Temperature Analog Channel Furictional Test -d T Overtemperature anddT V
Overpower,'was performed with Unit No. 2 in the cold shutdown cozidit4.on.
The limiting safety system settings of Channels I i
and III of the Overp3wer6T Reactor 'lrip circuitry were found
[
to be below that required by Technical Specification 2.3.1.B i
(5),
channels II and IV were found to be operating correctly.
[
Channel III was recalibrated and tested satisfactorily.
Re-E pair of Channel No. I will be completed prior to reactor start-1 up.
E Safety implications of this discrepancy are considered slight since the reactor was in a cold shutdcwn condition and the re-au E
maining trip circuits would have provided complete reactor pro-tection again6t an excessive flux tilt even if this had not been g
the case.
The maximum error found would have resulted in the 0
{
actual reactor 6T exceeding the limit by 0.15 F in achieving an overpowera T trip.
In an effort to determine the cause of these deviations and pre-E viously reported ones of a similar nature, our Engineering De-E partment is continuing the investigatlon mentioned in our letter to you dated December 18, 1973.
