Sentences with phrase «reactor coolant»
Reactor coolant refers to the fluid that circulates through a nuclear reactor to help regulate its temperature. It carries away the heat generated by the reactor's core, preventing it from overheating. Full definition
So has securing delivery on certain components, such as reactor coolant pumps, because they are being produced for the first time.

Tritium is produced primarily from neutron capture by B - 10 in PWRs; that B - 10 (in the form of boric acid) is added to reactor coolant systems as a soluble reactivity agent.
The unit's reactor coolant loop pipe welding and the setting of other key equipment have also been completed, the Emirates Nuclear Energy Corporation (Enec) said yesterday.
Water - cooled systems run at very high pressure, so that a small leak can quickly develop into a large release of steam and perhaps a serious pipe break, with rapid loss of reactor coolant.
Zirconium readily generates explosive hydrogen gas if reactor coolant stops circulating.
This clutter of the commons is a mix of dead spacecraft, spent rocket stages, steel bolts, paint chips and even frozen bits of nuclear reactor coolant.
The integrated design of the NuScale Power Module, encompassing the reactor, steam generators, and pressurizer, and its use of natural circulation eliminates the need for large primary piping and reactor coolant pumps.
The low power output of each NuScale Power Module allows for significant design simplification and elimination of many systems susceptible to sabotage, including the reactor coolant loops, reactor coolant pumps, and active safety systems.
Although SMR - 160 is a pressurized water reactor, it does not use boric acid in its reactor coolant system.
The slow up - flow of water in the reactor vessel insures that little radioactive crud produced from long term operation carries to the above - ground portion of the reactor coolant system.
The nature of density driven flow is such that as the heat generation from the core is throttled, the reactor coolant temperature profile changes but the mean coolant temperature remains substantially constant.
The slow upward flow of water insures that the short lived radioactive gases produced by fission die off before the reactor coolant reaches the above - ground portion of the plant (another bonus of gravity driven flow!).
Except for the reactor coolant system and the fuel pool, the balance of the SMR - 160 plant is essentially sequestered from radiation.
