3. High and Low Pressure Injection Analog Channel Test (3 .y

'k/ The inspector reviewed Surveillance Procedure 1303-4.11, Rev. 8 dated 8/12/75. This procedure is used to implement the monthly test required by Technical Specification 4.1-1, item 1 The three ,

'

Reactor Coolant Channels are tested by applying an analog voltage F signal to the pressure trip bistables and verifying that the vol-

,

tage required to trip them corresponds to pressure trip points of 1540 to 1550 psig and 540 to 550 psig. Technical Specification 3.5.3.1 requires these setpoints to be, respectiver 1500 psig and 500 psig, or greate The inspector revieued the surveillanc'e records for SP 1303-4.11 which were perforced on 7/6/75, S/6/75 and 9/5/7 The data shcets indicated that the procedure was completed at the required frequency (monthly), and that the pressure setpoints were in accordance with T.S. 3.5. .

.

iE The inspecto'r found no inadequacies in this are . Reactor Building Spray Actuation Setpoint The inspector reviewed Surveillance Procedure 1302-5.11 "Rea.ctor Building 30 psig Pressure Channel" which is used to adjust or check ('~'} >

the Reactor Building Spray actuation setpoint bd be less than or -

equal to 28.5 psi Technical Specification 3.5.3.1 requires this (_cj value to be less than or equal to 30 psi The inspector reviewed the surveillance records for SP 1302-5.11 which was performed on .

• ~

1/15/74. These records are still applicable since the channel calibration is required each refueling period (T.S. 4.1.-1 T21).

This.vas the initial calibration and the pressure sett.oint was set at 28.5 psi .

The inspector found no inadequacies in this are . Reactor Protection System Channel Bypass Key The inspector determined, by discussion with the licensee, that only one channel bypass key was in the control room in accordance with Technical Specification 3.5. Plant keys are kept in a key locker adjacent to the Shift Foreman's desk. This key locker is normally locke When any key is removed, the person charged with z.; .

any given time. The inspector also observed that only one such key fll E!:T!.?

was available in the key locker. By inspection and discussion, the inspector determined that the licensee scheduled RPS surveillance _

,

testing on a one channel per week basis and therefore the surveil-lance schedule aids in preventing any attempt to bypass two channels J34

Pumps were shutdown from 9/27/75 to 9/30/7 By discussion with sj the licensee and review of the Shift Foreman's log the inspector "

f s_ It ha 1 Variable Low Coolant Pressure Trip Setpoint The inspector review'ed SP 1303-4.1, " Reactor P: icction System Surveillance," which is used to check and/or ad3ust the Variable Low Coolant Pressure Trip Setpoint at a value greater than or equal

,

to the requirements of T.S. 2.3-1T6. (16.25T out-7756). Procedure 1303-4.1 Section 6.8.5 verifies that at a Reactor Coolant Outlet temperature of 5900F the pressure trip setpoint is greater than or equal to 1831.5 psig and at a temperature of 604cr t.he setpoint is .g greater than or equal to 2059 psi The procedure steps perform @

this verification by inputing to the trip bistable the voltage E value corresponding to the temperature listed above and then de- _

creasing the voltage input which simulates a decreasing reactor E pressure until the bisttbic trips. Tae trip voltat;c is then re- f corded and compared to licensca determined voltages.which correc-pond to the pressure values listed abov gjj

+a The inspector reviewed those Data Sheet 6, items 4 and,7 of SP 261 1303-4.1 which were completed in July, August and September of 1975 for each pressure and verified that the "as found" Variable Low Coolant Pressure Setpoint based on an analog input voltage was greater than required by T.S. 2.3-1T6. The inspector noted thet for Data Sheet 6 step 6, completed on 7/22/75, the analog voltage (, ) used to simulate reactor temperature was recorded as -0.084, how-

) ever, the required accuracy is +0.0002. The li.densee stated that y; 6 the value should have been recorded as -0.0840 and that Data Sheet .

"

the licensee to implement Technical Specification 2.3-1T1, Nu-lear Power Trip Setting of 105.5%. SP 1303-4.1, " Reactor Protection System Surveillance," is performed monthly on each RPS Channe Section 6.5.8 of that procedure verifies that the High Flux trip bistable is set at less than or equal to 105.5% and adjust the trip setting to be 104.75%. SP 1302-1.1, Power Range Amplifier Calibra-tion, is performed on a minimum of twice weekly and is used to i adjust the output of the power range amplifier to a value equal to j core power as determined by a heat balance calculatien. The power 'l range amplifier providas the analog input to the dirh Flux trip bistabic and therefore, the calibration of this sapitfier is necessary to i;he accuracy of the Nuclear Overpower Irip Settin Q J 90012533 cv V

comment on these surveillance records,

"# RPS surveillance test SP 1303-4.1 was performed 12 times during July, August and September of 197 The inspector

reviewed Data Sheet 3 for each of these surveillance tests to determine that the High Flux Eistable was set at 1 css then or equal to 105.5%.

1he licensee stated thct recording of the bistable input was a " backup" to the previous-ly recorded value of the input to the linear amplifier and therefore, since that value had been recorded, the bistable trip was in compliance with T.S. 2.1-1T1 (105.5% overpower trip).

Technical Specification 6.2.3 states in part: "rit . t en procedures shall be strictly adhered to in all matters re-lating to nuclear safety." Contrary to this Technical Spec-ification, the requirements of SP 1303-4.1 Data Sheet 3, item 3, were not adhered on two occasions 7/22/75 and 9/24 7 / .:
