.2 ALGORITHMS USED FOR SETPOINT/0VERSMDOT DETERMINATION
.4.2.1 Setpoint Determination for Mass Input Transient
Determination of a relief valve setpoint which will not result in a peak pressure In excess of the Appendix 6 linit, for the case of miass Input as applied to a specific operating plant, Is accompl1shed with a procedure based on the following simplified interpolating equation:
aP (V, S Z, X) E APREF (x) * FV FS * FZ
The procedure for determining the relief valve setpoint Is described below. To illustrate the application of the procedure, -a set of sample input parameters will be considered, and the results of the sequential application of each step of the procedure to these parameters will be noted.
PARAMETERS FOR KASS INPUT EXAMPLE
Relief Valve Setpoint * 500 psig Relief Valve Opening Time = 2.0 seconds. Mass Input Rate 60 lb/sec RCS Volume * 10,000 cu.ft.
Applying the r-ass input procedure:
AI
- ATTACf4. rTA
p. 217 1523 70
t Procedure Example Apication
I Select relief valve setpoint Setpoint * 500 psig
operating range
2 For limiting mass input rate, APREF-' 82 psi for mass input
obtain &PREF from Figure rate (x) * 60 lb/sec
4.2.1
3 For total RCS volume, obtain F . 0.71 for total RCS volume
F factor from Figure 4.2.2 (V) = 10,000 cu.ft. V
4 For the relief valve opening FZ = 0.733 for relief valve
time (total, including delay), opening time Z = 2.0 seconds
obtain Fz factor from Figure
4.2.3
5 For the relief valve setpoint F5 a 1.14 for relief valve
selected, obtain FS factor setpoint = 500 psig
from Figure 4.2.4
6 Calculate the product of fac- AP (10,000 cu.ft., 500 psig,
tors aPREF' F , F5, and Fz 2 seconds, 60 lb/sec) £ 49
determined in Steps 2 through psit
5 (application of Equation 1).
This is'the setpoint overshoot,
AP.
t Conservative - LOFTRAN analysis for these conditions gives an overshoot
equal to 25 psi.

BUL Procedure Example Application
7 Add AP (Step 6) to the relief a 515 psia (relief valve valve setpoint (Step 1) to setpoint) plus 49 psi, or 564 obtain maximum transient pres- psia. Frofn Figure 4.2.5 at RCS sure, P MAX - temperature 100F Appendix Appendix G limitation, se- pressure limit 540 psig + 15, lected relief valve setpoint or 555 psia. Thus, is acceptable. If PMAX Appendix G limitation. Appendix G limitation, go to Step 8.
8 if PMAX > Appendix G limita- Reducing setpolnt by 10 psi tion. selected relief valve (564 psia - 555 psia ) to 490 setpoint It too high. Reduce psig and repeating Steps 2 setpoint and repeat Steps 5 through 6 results in AP e 49.4 through 7 until an acceptable psi and P 505 psi + setpoint is determined. 49.4 554.4 psia. Since 554.5
psia < Appendix limit, 490 psig is an acceptable setpoint.
