Abstract
High Heat Flux Test Facility (HHFTF) at Institute for Plasma Research in Bhat in India is established for testing thermal performance of plasma facing materials and components under intense heat loads expected in plasma fusion devices. It mainly consists of the following sub-systems like vacuum system, high power electron beam system, diagnostic and calibration system, data acquisition & control system and high pressure high temperature water circulation system (HPHT-WCS). In order to test the water cooled test mock-ups or components at ITER like relevant parameters in HHFTF, HPHT-WCS is established that can supply water at desired pressures, temperatures and flow rates. HPHT-WCS, is capable of providing demineralised water up to 160°C temperature, 60bar pressure and 4.85kg/s mass flow rate. The loop is designed on a skid base frame which has piping connected to various process components and the system is operated remotely through a data acquisition and control system. The main requirements and characteristics, design and development of the HPHT-WCS are presented.
