PHYSICS DEPARTMENT thesis: DETERMINATION OF THE DISTRIBUTION OF POWER REACTOR FUEL NPP loaded thorium
Fuzaeatun. , 2006. Thesis PHYSICS DEPARTMENT, FACULTY OF MATHEMATICS AND NATURAL SCIENCES, STATE UNIVERSITY SEMARANG
One of the growing utilization of nuclear technology in the field of energy is nuclear power. Power generated from the fission reaction. Some of the atoms that can react U235 and U233 fission is. U235 materials found in nature, whereas the U233 does not exist in nature, but the results obtained from neutron capture in Th232. The success of making a new fissile material U233 from Th232 bring people to the idea to create a reactor with a fuel modified by adding Th232 for U233. The device is fuel modification can affect the behavior of the reactor, one of them on the distribution of power.
Determination of the distribution of nuclear power reactors with thorium fuel is loaded using the CORD-2 program. CORD-2 program is a computer program to design a terrace reakor PWR type. CORD-2 program consists of procedures to prepare the input data file for WIMS program to group constant data file for input GNOMER program. WIMS program for calculation of group constants data and program data GNOMER for homogenizing global constants in the core group and the calculation of the power distribution at zero power and full power. In the CORD-2 program requires a code that has many functions, such as: maintenance of libraries, the name of the type of data and preparation of input for reactor physics codes.
The results obtained from the program files CORD-2 form the reactor core design and reactor core power distribution. From these results, due to the addition of thorium to uranium-235 as fuel for power reactors led to falling prices on the outskirts of the reactor core (3% enrichment). This is because the number of fission neutrons in the reactor core partially absorbed by thorium which has the look of high-latitude absorption of heat result in decreased production in the reactor core.
Can be concluded that the distribution of power due to the addition of thorium at the highest level of enrichment to be small compared with no added thorium. The addition of thorium can extend the life of the reactor operation.
