Atomic-powered ship has ability that is environmentally protective, infinitely continuing a journey, and the development of atomic-powered ship is also made to have broad application prospects.
Nuclear reactor is nuclear heart, it is to generate amount of heat by the chain reaction that nuclear fuel rod is fissioned, this
A little heats must be taken out of (or being used effectively, or cooled processing) in time.If this partial heat is not taken out of, heat is just
It can assemble, temperature is stepped up, and leads to core meltdown, and then radioactivity cannot contain, and generates radioactive release, is caused serious
Nuclear accident.
Nuclear reactor has a feature, once fuel rod starts to react, just ceaselessly generates heat, though reactor shutdown it
Afterwards, nuclear reaction is still continuing, and can not stop the short time, and need the long period slowly calms down process, and the release of this process is a large amount of
Heat.On the other hand, even if fission reaction stops completely, those fission generation decays can also discharge heat.Therefore reactor one
Denier is devoted oneself to work, and regardless of whether midway stops working, is required to provide steady and sustained cooling.
Ship is in briny environment, is arranged sea chest (sea suction), taking away extra heat using seawater is
Efficient and conventional means.However atomic-powered ship and normal shipboard except that stranded, the bases such as hit a submerged reef, crash occurring
After quasi- accident, it is still desirable to which the refrigerated sea water to maintain a long-term stability avoids radioactivity to guarantee the Residual heat removal after emergency shut-down
Contain and destroys.
