4. Path to Achieve the Goal • Establishing Nuclear Safety Laboratories in Universities / Institutes. • These laboratories will not use any Nuclear Fuel. • No issues are related to the Safety of the Laboratory or its employees. • We will train students with the help of Nuclear Reactor Simulator known as RELAP5. SCDAP Development & Training Program Page 4

5. Introduction to RELAP5 • RELAP – Reactor Excursion & Leak Analysis Program, • Developed at the Idaho National Engineering Laboratory (INEL) for the U.S. Nuclear Regulatory Commission (NRC), • Basis for a nuclear plant analyzer, • Calculates the behavior of a reactor coolant system during a transient, • Used for simulation of a wide variety of hydraulic and thermal transients. SCDAP Development & Training Program Page 5

6. Introduction to RELAP5 • Both nuclear and non-nuclear systems involving mixtures of steam, water, non-condensable, and solute can be simulated. SCDAP Development & Training Program Page 6

7. Introduction to RELAP5 • RELAP5 code is based on a nonhomogeneous and nonequilibrium model for the two phase system. • This system is solved by a fast, partially implicit numerical scheme. • RELAP5 MOD 3.3 has been developed jointly by the NRC and a consortium consisting of several countries. SCDAP Development & Training Program Page 7

8. Introduction to RELAP5 • Various Department of Energy sponsors, including the INTEL laboratory- directed discretionary funding program. • The mission of the RELAP5 MOD 3.3 development program was to develop a code version suitable for the analysis of all transients and postulated accidents in LWR systems. • Code includes component models from which general systems can be simulated. SCDAP Development & Training Program Page 8

9. Introduction to RELAP5 • Special process models are included for effects such as: • Form Loss, • Flow at an abrupt area change, • Branching, • Choked Flow, • Boron Tracking, • Non Condensable Gas Transport. SCDAP Development & Training Program Page 9
