Of 44 tripping tests ran for both relays in-the loop techniques, the breakers near the fault tripped and the other breakers remained closed in 34 cases, and backup relays tripped when primary relays did not trip in 10 cases (backup tests).
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.
In the simulated trip test, the circuit assumes a 220 V ac power contact with a transition current of 1 Arms and the response time of the thermistor is measured under a range of ambient temperatures.
However, more than ten participants were employed and they finished a round trip test on each road, and therefore, the distance travelled by these drivers approximated 1500 km, which could remedy the defect of insufficient participants sample to some extent.
