Reactor Cooling System



 The Reactor Cooling System of the HTTR is composed of a main cooling system (MCS) , an auxiliary cooling system (ACS) and a vessel cooling system (VCS). The MCS consists of a primary cooling system (PCS), a secondary helium cooling system (SHCS) and a pressurized water cooling system (PWCS), as schematically shown in the figure below.
 Under the normal condition, the heat of 30 MW generated in the reactor core is removed by the MCS.
