Operation and control strategies in pre-series testing of cold circulating pumps for ITER Bhattacharya R.1, Vaghela H.1, Sarkar B.1, Srinivas M.1, Choukekar K.1 1ITER-India, Institute for Plasma Research, Near Indira Bridge, Bhat, Gandhinagar-382428, India, Abstract Cryo-distribution system of ITER is responsible for the distribution and control of forced- flow supercritical helium for cooling of the superconducting magnets and the cryo-pumps. The requirements of cold circulating pumps (CCP) for mass flow rates and performance are much higher than presently existing and commercially available one used at 4.0 K helium. Design up-scaling with pre-series test of CCP has been proposed including test infrastructure. Operation and control strategies for the test distribution box (TDB) of test infrastructure have been developed and analyzed using steady state and dynamic process simulation to cope with the functional requirements of CCPs. Off-normal scenario with CCP inlet pressure variation is an important concern, dynamic process responses during such scenario have been evaluated to verify the operability of CCP. The paper describes process simulation to cope with the functional requirements of CCPs along with evaluation of off-normai scenario to verify the operability of CCP.
