采用液体金属冷却剂的645型核潜艇核反应堆采用液体金属冷却剂,能够有效地提高核反应堆的功率。645型(N级改进型K-27号)核潜艇搭载有2座VT-1型核反应堆,总功率高达35000马力,比 627／627A型(N级)核潜艇搭载的VM-A 型加压水核反应堆增加了4．3％。液体金属 (一次冷却材料)的循环为自然循环,不需要以往成为噪声源的冷却泵。另外,二次冷却系统的压力要高于一次冷却系统, 因此即使蒸汽发生器出现故障,也不用担心放射能会泄漏至二次冷却系统。 645型核潜艇最初是在佩莱格多夫少
The use of liquid metal coolant 645 nuclear submarine nuclear liquid metal coolant reactor, can effectively improve the power of nuclear reactors. The Model 645 (N-Modified K-27) nuclear submarine is equipped with two VT-1 nuclear reactors with a total power of 35,000 horsepower, an increase over the VM-A pressurized water nuclear reactor equipped with a 627 / 627A 4.3%. The circulation of liquid metal (primary cooling material) is a natural cycle, eliminating the need for a cooling pump that used to be a source of noise. In addition, the secondary cooling system pressure is higher than the primary cooling system, so even if the steam generator fails, do not have to worry about leakage of radiation to the secondary cooling system. The 645 nuclear submarine was originally less in Pellegrod
