• Note (General): A plant transient analysis code has been developed to analyze the thermal hydraulics in the primary cooling system, coupled with dynamic characteristics of the residual heat removal (RHR) system and the reactor core isolation cooling (RCIC) system. A new numerical scheme named "flow distribution function" has been developed to calculate long term transients quickly. Prediction accuracies of the code for each function of components, such as thermal transient of a heat exchanger, thermal transport in a pipes, and flow control characteristic of a control system were examined by the experimental data obtained from the tests using the full mock-ups of the advanced thermal reactor (ATR) and the prototype reactor "Fugen". Prediction accuracy for the whole plant behavior was verified by the test simulating the loss-of-power-transient with succeeding RCIC injection at the "Fugen". Main parameters of the plant are predicted within $\pm$10\% error. The CPU time needed for the calculation is about 1/30 - 1/300 of the physical time when a super computer VP-100 is used.; None
