Minimization Of Reactor Dead Time By Power Monitoring In Slow Shut Down Mode

Research outputpeer-review


A study on minimization of the dead time when a research reactor can not be restarted during ~ 40 hours due to xenon-135 poisoning is presented. Theoretical considerations based on reactor dynamics equations together with the SCALE4.4a modules system are used to choose an optimum power monitoring regime in a slow reactor set back. Utilizing different power monitoring scenarios in an extended shutdown period of 1520 hours a reduction of the reactor dead time up to 68% in comparison with sudden shutdown mode (scram) is obtained at energy savings (MW.d) equivalent to ~ 15 hours of full power operation.
