* a zirconium-steel sheath of fuel assembly
which does not allow the products of fission of fuel to enter the coolant of the main circulation circuit;
A numerical investigation of the thermal and hydro dynamical processes which take place inside the fuel channel of the RBMK-1500 reactor during interaction between the coolant and the fuel assembly
, was presented in .
The temperature distribution in the solid region which includes the graphite of fuel assembly
, reflector, and reactor vessel is calculated by the three-dimensional heat conduction model.
Tatarkin noted that the fuel will be loaded one-by-one in the remaining cells, instead of fuel assembly
dummies, in accordance with the operating schedule.
The supply chain team reported that decreased forces in the fuel assembly
reduced the propensity for the assembly to bow and eased the on- and off-loading of the reactor core.
As was the case with the first nuclear fuel assembly
taken out Wednesday, TEPCO used a crane to remove the second one from the pool on the fifth floor of the reactor building, cleaned it with pure water and put it into a special container, the sources said.
During the Commission's investigation, concerns materialised as to possible effects on potential competition in the fuel assembly
markets of the combination of Toshiba's stake in GNF with its control of Westinghouse.
Unlike the first survey, made by inserting a camera 5 feet into the core area, the latest pictures were made possible by feeding the pencil-like 9-inch-long camera down the narrow passage between the side wall of the reactor vessel and the core's fuel assembly
. What the fist-sized rocklike fragments (imaged in the center of photo) are made of is still unknown, according to Lisa Robinson, a GPU Nuclear spokesperson.
Tenders are invited for a contract for post-reactor studies of the central rod of the fuel assembly
Lightbridge Corporation announced that it has received a Notice of Allowance for a new patent in Japan related to Lightbridge's innovative metallic fuel rod and fuel assembly
In order to decrease complicated solving parameters in using compressible fluid method, geometry of every fuel assembly
could be turned into a single heated channel (SHC).
The fuel assembly
of the BWR reactor has a quadratic cross section and usually consists of the 64 fuel elements.
