- Summary
- DlORIT is a D/sub 2/O inoderated, E/sub 2/O cooled, testing reactor using 6 tons of natural uraniuin at a speeific powcr of 2 to 4 Mw pcr ton. As the effluent froin the individual cooling shrouds overflows into the bulk of the moderator a verv efficient negativc reactivity feedb.ick is cxpected in the pow- er range. The mechanism of this fecdback being of major iinportance for the dynainie properties, a nuclear reaetor siniulator eontaining:i special temperature unit was used to investigate the dynamic behavior of DIORIT. A short descrtption is given of the simulatora and soine coinputations on safety aspects are surainarizcd. ln particular the influenc- of fast changes of primary- and second:iry- cooling r:itcs, possible startup accidents, and the tiinc dependance of power after a fast shutdowan arc investigated. Transfer functions of thc reactor at different power levels are obtaincd and thc performance of the automatic control system is discusscd. The results yield a sound basis for the 1ayout of the control and safcty circuits and the- proper choice of operational conditions. (auth)
