One of the methods detetmining shut down of control reactor rod is rod drop test. The Analysis data has been done using the inverse reactor kinetic aquestion, and KINIK computer code to find shut down reactivity value. The shut down reactivities of reactor TRIGA Mark II-Bandung rods are 2,357% dk/k (safety rod), 0.830% dk/k (shim I rod), 0,656% dk/k (shim II rod) and 0,136% dk/k (regulatory rod…
