The gas circulators trip tests, in which position of control rods are kept unchanged, are simulation tests of anticipated transients without scram (ATWS).
While the exposure of patients to effective novel treatments is a benefit of clinical trials, this must be balanced against the fact that in randomised studies patients may experience greater inconveniences (trips, tests, etc).
Family road trips test everyone's patience.
The tests contain (1) loss of feedwater heater test, (2) one feedwater pump trip test, (3) one reactor internal pump trip test, (4) three reactor internal pumps trip test, (5) loss of offsite power and turbine/generator trip test, (6) turbine trip test, (7) load rejection test, (8) fast load winddown test, and (9) reactor full isolation test.
In this article some typical power tests simulation and comparison results are presented for (1) one feedwater pump trip test, (2) one reactor internal pump trip test, (3) load rejection test, and (4) reactor full isolation test.
The coolant flow reduction test consists of the partial loss of coolant flow test and the gas circulators trip test.
A selected computation case is the turbine trip test conducted at 40% electric power of the prototype fast reactor "Monju".
In the current paper, a contribution to the assessment and validation of coupled code technique through the Kozloduy VVER100 pump trip test is performed.
In the gas circulators trip test one and two out of three gas circulators are run down, simulating coolant flow reduction events.
In this study, an all-gas-circulator trip test was analyzed as a loss of forced cooling (LOFC) test with an initial reactor power of 9 MW to demonstrate LOFC accidents.
