Nuclear Reactor Core Problems:

Material problems in a nuclear reactor plant could be grouped into at least two classifications, one concerning the nuclear reactor core and one which will apply to all plant materials. This lesson elaborates exact material problems related with the reactor that involves pellet-cladding interaction, fuel- cladding embrittlement, fuel densification and effects on the fuel because of inclusion and core burnup.

STATE nuclear reactor core problems and causes related along with the following:

a. Pellet-cladding interaction

b. Fuel densification

c. Fuel cladding embrittlement

d. Fuel burnup and fission product s welling

STATE measures taken to counteract or minimize the effects of the following:

a. Pellet-cladding interaction

b. Fuel densification

c. Fuel cladding embrittlement

d. Fission product s welling of fuel elements
