Sentences with phrase «reactor vessel for»

Considering the condensing ability of the steam generators, water inventory in the HA - 2 tanks was chosen so that coolant inventory essential for reliable cooling of fuel can be maintained in the reactor vessel for 24 - 280 hours (depending on leak size).

When a chemist needs a novel reactor vessel for an experiment, Ramsey heads to his workshop and fires up his precision flamethrower.

Yes, the reactor vessels for all these nuclear plants, and many others worldwide, were manufactured by Combustion Engineering at their factory in Chattanooga, Tennessee.

Not exact matches

The faulty bolts were discovered during an in - depth inspection of the Indian Point nuclear reactor vessel scheduled for once every decade.

Radiation levels are too high for an inspection, but the damage is thought to have been to a doughnut - shaped tank directly beneath the reactor vessel.

Sheron said — for example, the concrete supports for the reactor vessel that are subject to radiation exposure.

Put it this way: If you're designing a nuclear reactor containment vessel, do you design it for the 5 % chance that the pressure in a meltdown is 100 atmospheres or the 5 % chance that the pressure in a meltdown is 10 atmospheres?

Containment vessel submerged in an ultimate heat sink for core cooling in a below grade reactor pool structure housed in a Seismic Category 1 reactor building.

The vacuum also enhanced steam condensation rates on the inside surface of the submerged containment in the case where steam is vented from the reactor vessel, which in turn provides for very effective heat removal from the primary system.

In other words we have to look elsewhere for reactor vessels, steam generators, pressurizers, etc..

Long term waste disposal seems a major sticking point for a lot of people, leaving aside short term, insane choices such as storing spent fuel high in the air on top of reactor vessels so as to save plumbing and thus money.

Flouride salts hold heat almost as well as water, so make for good coolant, but remain liquid up to 1300C, so unlike water - cooled reactors can operate at higher temperatures, for better efficiency, and without pressurized vessels, making them both safer and less costly.

In fact, certain of TEPCO's actions in the aftermath of the explosions have been confused and, some might opine, lacking discipline of purpose to the extent that expedient decisions have been made without proper forethought and judiciousness to avoid knock - on consequences: for example, the injection of seawater may have resulted in salt deposits sufficient to foul cooling flows in the lower regions of the RPV [reactor pressure vessel]; the liberation of hydrogen from seawater is more rampant than from freshwater and radiolysis of oxygen from the cooling water could provide stoichiometric conditions and ignition with hydrogen in the absence of air in the containments; and the latest and most recent announcement to deploy a nitrogen purge to the Unit 1 reactor seems yet another ill - explained and unjustified desperate measure».
