O IMPROVED SRV DISCFARGE LOAD DEFINITION (OBJECTIVE #1) 801002040><
IfiPROVED DESIGN LOAD SPECIFICATION FOR SINGLE VALVE DISCHARGE:
o DERIVED FROM STATISTICAL ANALYSIS AND ENGINEERING EVALUATION OF CAORSO TEST DATA; o
CONFIRt1ED 'dITH TOKAI-2 TEST DATA.
LOAD CHARACTERISTICS FOR MULTIPLE VALVE DISCHARGE:
o OBTAINED FROM ENGINEERING EVALUATION OF CAORSO AND TOKAI-2 TEST DATA.
IMPROVED DESIGN LOAD SPECIFICATION FOR MULTIPLE VALVE DISCHARGE-o DERIVED FROM ENGINEERING JUDGEMENT; o
SUPPORTED BY CAORSO AND TOKAI-2 TEST DATA.
I s
l SINGLE VALVE DISCHARGE IPPROVED DESIGN LOAD SPECIFICATION CONSISTS OF:
I.
MAXIMUf1 PRESSURE Af4PLITUDE; II.
NORMALIZED PRESSURE TIi1E HISTORY (FREQUENCY CONTENT); AND, III.
SPATIAL DISTRIBUTION FOR PRESSURE.
t
LOAD DEFINED AS " RIGID WALL" PRESSURE IMPROVED SRV DISCHARGE LOAD IS DEFINED AS " RIGID WALL" PRESSURE, P (T), ACTING ON THE Whi tED PERIMETER g
OF A MARK II SUPPRESSION CHAMBER:
P;(T) = P (T) - Ppg ((T)
T TECHNICAL REASONS:
o AVAILABILITY OF MEASUREMENTS (P (TD PROM CAORS0* IN T
A GEOMETRY SIMILAR TO WNP-2.
o ENGINEERING EVALUATION INDICATES THAT FSI EFFECTS ARE NEGLIGIBLE FOR THE CA0RS0'S CONCRETE CONTAINMENT (Ppg ((T)ct: 0).
PRACTICAL REASON:
o SIMPLER /MORE ECONOMICAL WAY TO DEVELOP AN IMPROVED LOAD DEFINITION.
IN THE CAORSO PLANT THE SRVDL's ARE EQUIPPED NITH CROSS-QUENCHERS AS EXIT DEVICES, SIMILAR TO WNP-2.
~
EVALUATION OF FSI E:FECTS IN CAORSO INTERACTIVE PRESSURE COMPONENT, p 3;(T), OBTAINED FROM:
p Ppgi(T) = 11]5(T);
WHERE:
= THE ADDED MASS MATRIX, AND
.~.
,U(T)
= THE EOUNDARY ACCELERATION VECTOP..
a AN UPPER BOUND ESTIMATE IS:
Ppgi T) st: 2.84 ?
- 0.100 a = 0.23 Psi ;
t MAX.
WHERE:
2.84 y = LARGEST COMPONENT OF ADDED MASS MATRIX (CORRESPONDING TO ZERO HARMONIC) 0.100 a = LARGEST RECORDED CONTAINMENT ACCELERATION (CORRESPONDING TO SENSOR A13x/AMN)
CONCLUSIONS _:
?pg1(T)
NEGLIGIBLE o
o PRESSURE RECORDED ON CA0RSO SUPPRESSION POOL BOUNDARY MAY BE CONSIDERED AS " RIGID WALL PRESSURE.
