Studies of Control Rod Worth of TRIGA Mark-II Research Reactor Using Evaluated Nuclear Data Library JENDL-4.0u

The Japanese Evaluated Nuclear Data Library (JENDL) is the successful data library to study the important parameter of TRIGA Mark II research reactor. TRIGA Mark II research reactor is the successful reactor in our country. Controlling safety is very domineering to operate any nuclear reactor. The willpower of the reactivity worth of individual control elements and the effects of such elements on the power distribution in the core is important to the safe and efficient operation of a reactor. Once a control rod is calibrated, it is possible to evaluate the magnitude of other reactivity changes by comparing the critical rod positions before and after the change. The control system of a reactor must have the ability of shutting the reactor down safely at any time. Proper control rod worth analysis will provide the safety control analysis of the reactor. In this work the control rod worth of TRIGA Mark II research reactor is calculated using the evaluated nuclear data library JENDL-4.0u through the successful chain code NJOY99.0, WIMSD-5B and CITATION, and the calculated value are compared with the MNCP values. The obtained results of control rods worth are compared with experimental results of TRIGA at Atomic Energy Research Establishment, Savar, Dhaka, Bangladesh; and the reliability of the method was confirmed.
