Experimental test facility enabling exposition of materials to radiation environment is described. The facility enables research on behaviour of materials and water chemistry of PWRs and BWRs.

High pressure water loop RVS-3 is operated in LVR-15 test research reactor. The loop was designed as a universal facility providing wide experimental possibilities. Loop is designed for 16.7 MPa pressure, 334°C temperature, 10 t/hour water flow rate and 1.1014 cm−2. s−1 neutron flux. Water chemistry used corresponds the PWRs with boric acid and pH control by potassium/lithium, hydrogen control by gas or ammonia.

BWR loop is designed for investigation of structural materials and Water chemistry in conditions of boiling water power reactors. Loop has following parameters: 10 MPa pressure, 300°C temperature and 2 t/hour water flow rate.
