Another problem is the low thermal inertia and poor heat removal capability at low helium pressures, although these issues are shared with thermal reactors which have been constructed.
22.
Crews had installed temporary submersible seawater pumps and hoses to supply cooling water to the residual heat removal system heat exchangers as the main seawater pumps were heavily damaged by the tsunami.
23.
Additionally, as there was heavy damage to electrical equipment in the basements from flooding, temporary power connections had to be made to the residual heat removal system main loop pumps.
24.
Recent version of the Russian VVER have added a passive heat removal system to the existing active systems, utilising a cooling system and water tanks built on top of the containment dome.
25.
A much less common definition is : 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton ( i . e ., ) of water at in.
26.
Examples of isolation groups include the main steamlines, the reactor water cleanup system, the reactor core isolation cooling ( RCIC ) system, shutdown cooling, and the residual heat removal system.
27.
In contrast to current commercial fission reactors, hybrid reactors potentially demonstrate what is considered inherently safe behavior because they remain deeply subcritical under all conditions and decay heat removal is possible via passive mechanisms.
28.
In addition the mirror may heat simply because the edge of the diode laser which is electrically pumped is in less-than-perfect contact with the mount that provides a path for heat removal.
29.
The fuel pool and reactor core are now being cooled simultaneously, the fuel pool by the Fuel Pool Cooling System and Equipment Cooling Water System and the reactor core by the Residual Heat Removal System.
30.
In addition, the mirror may heat simply because the edge of the diode laser which is electrically pumped is in less-than-perfect contact with the mount that provides a path for heat removal.
