1.0 PURPOSE AND DESCRIPTION 1.1.
Purpose The purpose of this calculation is to verify the allowable value and nominal trip setpoint for the Reactor Dome Pressure Scram in the Technical Specifications.
1.2.
Setpoint Bases 1.2.1.
Loop Descriptions This loop consists of the instruments 1 B21 -PT-N078A/B/C/D and 11B21-PIS-N678A/B/C/D.
1.2.2. Design Bases Pressure sensors are furnished which, in conjunction with the Reactor Protection System, scram the reactor if reactor pressure increases, encroaching on the required margin of safety established for safety/relief valve setpoints. (Ref. 2.2.22, 2.2.23, 2.2.27) 1.3.
Desin Bases Event(s) 1.3.1.
The DBE for the high dome pressure scram setpoint is the closure of the MSIV's with pressure scram. The normal scram path associated with MSIV closure and High neuron flux are assumed to fail. (Ref. 2.2.45) 1.3.2. When the reactor is operating at less than full power, the high neutron flux scram may not be initiated. Under these conditions, the high dome pressure scram is credited. (Ref. 2.2.29) 1.3.3. Per Reference 2.2.39, the components in these loops are seismic category 1 instruments. Per Reference 2.1.1, seismic effects are not required to be considered for setpoint loops because the reactor will be shutdown following a seismic event.
Therefore seismic effects will not be considered for the subject loops.

4.0 ASSUMPTIONS 4.1.
All uncertainty values are assumed to be 2 sigma values unless specified otherwise.
4.2.
The M&TE values are assumed to be less than or equal to the reference accuracy of the individual devices unless the actual M&TE values are greater, in which case the more conservative value will be used.
4.3.
Because of the low dose rate associated with the normal environment for these locations (Total 40 Yr TID < 104), they are not considered "Harsh Conditions" and radiation drift will not be considered. (Ref. 2.2.38) 4.4.
Environmental Uncertainties for the transmitters are assumed to be determined by normal environmental conditions. The transmitter is not required to act under accident (LOCA) conditions, since this condition would lead to depressurization of the Reactor Vessel and prevent loop trip actuation. Containment pressure and temperature are assumed to remain at their normal operating values until the trip occurs.
4.5.
Not Used 4.6.
Not Used 4.7.
The over pressure analysis takes into account the pressure difference between the RPV bottom and the reactor steam dome pressure when establishing the high pressure scram setpoint. Therefore, no additional process measurement accuracy allowance is needed for the pressure difference between the RPV bottom and the steam dome. The process measurement accuracy allowance due to instrument line temperature is estimated to be less than one inch of water. Further, no primary element exists within the loop which could produce a primary element uncertainty; therefore no primary element uncertainty need be considered. (Ref. 2.2.45) 4.8.
The transmitter is not required to function in LOCA accident conditions. Any exposure to an elevated temperature for a short period of time is assumed to produce a negligible insulation resistance (IR) change. In addition, any insulation resistance losses will produce a positive bias which will tend to reduce the calculated uncertainty. (Ref. 2.2.24) Therefore it is conservative to assume IR losses are negligible.
4.9.
The loop power supply is a 24VDC safety related power supply. (Ref. 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.10). The power supply has a full load to no load variance of 23 VDC to 28 VDC.
The power supply is assumed to supply a nominal voltage of 24 VDC. Therefore, the maximum voltage variance will occur from the nominal voltage setting condition to a no load condition. The voltage variance used in the calculation will be 4.5 volts. This allows for the 4 volt change from the nominal condition to the no load condition and a 0.5 volt nominal voltage uncertainty to account for voltage ripple effect.
4.10. Not Used

[-ENTERGY SHEET 16 OF 33 CALCULATION NO.
JC-01B21-N678-1 REV. 002 4.11. The accuracy of the Rosemount trip units (+/-0.20% span) is valid for six months (Ref.
2.2.13). A calibration interval of 92 days plus a 25% grace period (115 days) will be assumed for the trip units (Ref. 2.2.33). Therefore, drift is included in reference accuracy.
4.12. The model number of the trip unit is not specified on the PPD 164C5150 (Ref. 2.2.9). It is currently a 510DU2 (except for 1B21N678A which is identified in the EDB as a 710DUOTT) based on the EDB (Ref. 2.2.39) and PERR91-6068 (Ref. 2.2.46). However, this PERR authorized replacement of the obsolete 510DU2 with the 71ODUOTT. The accuracy specifications of the 51ODU can still be assumed after the replacement since the 71ODU has better accuracy specifications.
4.13. Overpressure effects are not applicable because the maximum pressure that the transmitters are subjected to is a pressure of 1100 PSIG (Ref. 2.1.5, 2.2.6), which is below the URL of the transmitter (Ref. 2.2.40).
4.14. A 24 month refuel cycle will be assumed for the transmitters in this calculation. Applying
+25% margin (per Reference 2.1.1) yields a calibration interval of 30 months.
4.15. MTE Per Reference 2.1.1, the M&TE error is normally considered equivalent to the reference accuracy of the trip unit. Per Reference 2.1.4, a Rosemount 710DU Readout Assembly (+/-0.01 mAdc, per Reference 2.2.13) is used to calibrate the Rosemount Trip Unit.
The actual M&TE error (MTE2) for the Rosemount Trip Unit is = +/-0.01 mAdc, which is equivalent to +/- 0.9375 PSIG Output Range = 4 to 20 mAdc Input Range = 0 to 1500 PSIG 1500 PSIG 93.75 PSIG 93.75 PSIG x 0.01 mnade = 0.93 75 PSI 16 mAdc mAdc mAdc This value is less than the equivalent trip unit reference accuracy of +/-0.20% Span = 3.0 PSIG However, Per Reference 2.1.3 and 2.2.39, the trip unit is calibrated to +/- 0.04 mAdc which is equivalent to:
1500 PSIG 93.75 PSIG 93.75 PSIG x 0.04 made = 3.75 PSI 16 mAdc mnAdc mAdc This value is greater than the equivalent trip unit reference accuracy of +/-0.20% Span =
3.00 PSIG and the more conservative of the three values will be used.
MTE for Trip Unit = 3.75 PSIG Per Reference 2.1.4, a Heise pressure gauge (0-2000 PSIG) or equivalent (accuracy +/-
3.75 PSIG) and a Fluke model 45 Digital Volt Meter (accuracy +/- 0.04 mAdc) are used to calibrate the transmitter. The setting tolerance is specified as +/- 0.04 mAdc.

+/- (2/3)*[(0.0075*3000 PSIG) + (0.005*1500 PSIG)]* (15°F/100°F)
+/-13.00 PSIG Where AT is the maximum temperature variation during normal conditions.
The temperature variation is based on the maximum containment temperature above the normal value. For this case the maximum temperature variation is 150F (105'F
- 90'F). Therefore AT is 150F. The temperature variation assumed during calibration (90'F - 65'F) will be included as a temperature drift. (Ref. 2.1.1)
Temperature Drift TD,
+/- (0.75% URL + 0.5% Span)* AT/100°F (3a)
+/- (2/3)*[(0.0075*3000 PSIG) + (0.005* 1500 PSIG)]* (25°F/100°F)
= +/- 5.00 PSIG Where AT is the maximum temperature variation assumed during calibration. For this case the maximum temperature variation is 25°F (90'F - 65°F). (Ref. 2.1.1)
Therefore AT is 25°F.
