Radiation tolerance assessment of in-reactor equipment [at Sizewell B]

The operation of electrical and electronic equipment within Sizewell B requires that the equipment withstands the environment within the reactor. In particular, this places stringent limitations on the temperature and radiation tolerance of the system. The author considers the operations likely to be carried out within Sizewell B, describes some of the effects of radiation on electrical and electronic equipment and provides some guidance for increasing radiation tolerance to the desired levels
