O'Reilly, Director Regulatory Operations, Region I U. S, Atomic Energy Commienion t,31 Park Avenue King of Prussia, Pennsylvania 19406 Dear Mr. O'Reilly; In accorde.nce With the requirements of section 6.12.2a of the Technical Spoo.ifications of Facility Operating License No.
DPR-26, the fol10 wing report is submitted.
Periodic survei13ance test PT-M2, " Reactor Coolant Temperature hhalog Channel Functional Tee,b -L\\T Overtemperature and T QVer-power", was performed on Februnry 13/16, 1974 with Unit No. 2 in the cold shut.down condition.
The limiting safety systen set-e: j t.$ nga of Cha nnhl.a. 11 and IV of the Dvertemperature AT Re&otor
?.9 ;
Trip circuitry were found to be be10e thht h9 quired by Technical
).j:[.?
' Q('l Specification 2.3.).B (4).
Channal.; 1 and 111 were f ound to be Qi Operhting om rently.
Channele 11 and IV were recalibrated and tested satisfactorily, f Se*
Q :-
Safety Jwp).iostione of thie discrepancy are considered rJ ight "d 9 sinon the reactor was in a cold shutdown condition and the re-yC maining' trip circuits would have provided complete reactor pro-fii41s
,. M tection ogninnt an excecnive flux tilt even if this had not boon the eace.
The maximum error f ound would havn rnaulted in the ac-1 -k 0.30 P in achieving an U '. f 0
tual reactor 4T exceeding the limit by overtomparatt,arnA T trip for channele 11 cud IV.
hC kN in an effort. to data.rmine the cause of these deviationr, and pre-viously repor Wd onee of a similar natore, our investigation into this matter as discussed in our letter to Mr. John F, O ' 7..- a r y dated January 25, 1974 is continuing.
