The Analysis of TRACE/PARCS in the Simulation of Ultimate Response Guideline for Lungmen ABWR

In this research, the TRACE/PARCS model of 
Lungmen ABWR has been developed for verification of ultimate 
response guideline (URG) efficiency. This ultimate measure was 
named as DIVing plan, abbreviated from system depressurization, 
water injection and containment venting. The simulation initial 
condition is 100% rated power/100% rated core flow. This research 
focuses on the estimation of the time when the fuel might be damaged 
with no water injection by using TRACE/PARCS first. Then, the 
effect of the reactor core isolation system (RCIC), control 
depressurization and ac-independent water addition system (ACIWA), 
which can provide the injection with 950 gpm are also estimated for 
the station blackout (SBO) transient.
