Cooper Danger Will Robinson: if you change cell locations you may break the VB code!

SealType 0 Reactor coolant pump seal type tBatt 4.00 Battery depletion time (not used in the current formulation - tLong is what is actually used) tCoreUncovery 0.50 Core uncovery time tDGR50 4.00 Median diesel generator repair time tEPFail 0.00 Emergency power failure time (generally assumed to be 0.)

tLong 4.00 Long-term recovery time (this will generally be the battery depletion time!)

tShort 0.00 Short-term recovery time LOOPClass(1) TRUE Plant centered LOOP LOOPClass(2) TRUE Grid-related LOOP LOOPClass(3) TRUE Severe weather related LOOP LOOPClass(4) TRUE Extreme weather LOOP (1032 only, 5496 does not model this class)
