Information management of operation history for the fuel elements in SPRR-300

It is decided that only singular table is used to record the power history of the reactor, and one table is used to record the ratio of the relative neutron flux of every load for one element. Three kinds of tables in the database are linked by the field of Load ID. The element operation data of the inquiry can be derived to a pure text file which may easily be treated further. Because of the simplification of the structure of the operation history database for fuel elements, both a lot of unnecessary repetitive work in analysis and input and arduous manual calculation are avoided. So the data treatment for source term calculation of any element can be done in a relatively short time.
