PHYSICS DEPARTMENT thesis: EFFECT OF ADDITION OF FACTORS PERLIPATAN thorium neutron THE NUCLEAR FUEL TYPE PWR
Kristiana. , 2007. thesis PHYSICS DEPARTMENT, FACULTY OF MATHEMATICS AND NATURAL SCIENCES, STATE UNIVERSITY SEMARANG 2007
Nuclear reactor fuel materials can be split apart like the U-235 can also be used U-233, U-233 but not available in nature as to which U-235.
U-233 can be formed from the conversion of Thorium-232 after reacting with neutrons. Based on the above it is possible to memodisikasi nuclear fuel by adding thorium to obtain the U-233 which will then replace the U-235 burned during reactor operation. It lies behind the author to conduct research on the effect of the addition of thorium to the neutron perlipatan factor in the PWR type nuclear fuel.
Thorium additions made on the type of PWR nuclear fuel with the variation pattern of Almaraz II enrichment level 2.12%, 2.6%, 3.1% U-235, whereas the major determining factor for neutrons due to the addition of Thorium perlipatan on the nuclear fuel PWR type is accomplished using the WIMSD-4, made with WICORD program that is part of the program CORD-2003.
The results showed after the addition of Thorium (1-5%) rates decreased neutron perlipatan factor. The fall in prices caused by factors perlipatan neutron Thorium has the look of high-latitude absorption. On the enrichment of 2.12% U-235 is the addition of Thorium maximum 1.5%, while the enrichment of 2.6% addition of Thorium can be done (1-5%) and at 3.1% addition of Thorium enrichment should be done between (4 - 5%).
The conclusions of this study is that nuclear fuel should be loaded or Thorium is added fuel to the enrichment medium (2.6%). Recommended further research on the addition of Thorium can be done until more than 5%.
