High heat flux test facilities of various kind are being used worldwide to investigate the performance of plasma facing materials/ mock-ups/ components under estimated thermal load conditions in various plasma fusion devices. A new high heat flux test facility is being set-up at IPR to perform thermal load testing of plasma facing materials/ mock-ups /components. It will be equipped with a high power cylindrical electron beam used as heat source having maximum beam power of 200 kW @45kV having static and dynamic deflection angle of +/- 25 and +/-10 degree respectively that allow testing of large size components up to 1m x 1m surface area. The beam can be operated to simulate quasi-steady state as well as transient heat loads over test objects by either rastering it over test object at high frequency (up to 10kHz) or by operating it in pulsed mode (t > 1ms). The electron beam is horizontally mounted on a large volume (~ 5 m3) D-shaped double-walled vacuum chamber with target-handling facility that can handle large sized test objects weighing up to 1 ton. High pressure Water loop system, High pressure Helium loop system, Thermal diagnostic systems and Data Acquisition & Control system will be integrated with the facility for testing water cooled as well as helium cooled plasma facing components.

PHT-WCS (Tested and Commissioned)
The high pressure high temperature water circulation system (HPHT-WCS) has been designed to cool down the test mock-up which is connected to the HHF test facility. The test mock-up connected to the water circulation loop has a maximum heat load of 210 kW. In this test loop de-mineralized water (D.M water) is used as a working medium and system can operate in the pressure range of 5 bar to 60 bar and the temperature range of 25 degree C to 160 degree C with a maximum flow rate of 300 LPM. Inert gas pressurization method is used to pressurize the DM water in the pressure vessel using nitrogen. The nitrogen source (bank of nitrogen cylinders) connected with pressure vessel and a pneumatic pressure regulator controls flow of nitrogen in to the pressure vessel. The data acquisition system (DAS) with instruments is installed along with the test facility to record and control the test parameters pressure, temperature and flow rate. The test loop is designed as per relevant safety standards.
The major components of the test loop are reservoir tank, two positive displacement pumps with motor, pressure vessel with accessories, bank of nitrogen cylinders, two booster pumps with variable frequency drive, vortex type flow meter, heater bank, cooling unit, different types of valves at various locations, safety devices, pressure, temperature, level and other sensors/ indicator/transmitters with controllers. A detailed engineering design of various components like pressure vessel, heat exchanger, cooling tower along with thermo hydraulic analysis has been carried out.
