l o t a l Iscram calibration check and found two pressure transmitters were indicating low pres-l 10141 Isure and could have caused the primary coolant high pressure switches to trip above l

lo#sl [ the limits of LCO 4. 4.1, Table 4.4-1.

This is being reported por Fort St. Vrain Tech-l o is l Inical Specification AC 7.5.2(b)1 and AC 7.5.2(b)2.

No affect on public health or l

l li1il iThe pressure transmitters were calibrated.

Once a month, on a temCorary bt.ais ther I

j pressure transmitter voltage outputs will be checked against reactor pressure to J
