| Summary: | Warm water layer system is a protection system that protect the
environment and the workers above of the reactor pool from radiation exposure
which carried by the primary coolant. The system forms the warm water layer at
the surface of reactor pool for about 1,5 m thick and temperature for about 8 to 10
oC slightly above of the reactor pool temperature.
Computational fluid dynamics can be used to analyze the characteristics of
the warm water layer. One of the powerful computational fluid dynamics software
is FLUENT and it is used to anlayze the warm water layer at the G.A. Siwabessy
multipurpose reactor.
The results show that the increasing of warm water inlet temperature can
increase the warm water layer temperature range which the safety system
required. But it does not effect to the warm water layer thickness and population.
In the other hand, the increasing of warm water layer inlet flow can increase the
warm water layer thickness but not to the warm water layer temperature range.
The effectiveness of warm water layer initially starts at 15 m3/h and 50 oC of the
warm water inlet flow and temperature. At this condition, the warm water layer
can block the primary coolant to reach the reactor pool�s surface. |
