TECHNOLOGY FOR EXPERIMENTAL EVALUATION OF THE
MECHANICAL COMPRESSION RESISTANCE AT IMPACT
LOAD ON CANDU TYPE FUEL BUNDLE
The paper is referring to the test technology evolution of CANDU
experimental fuel bundle at the Institute for Nuclear Research Piteşti. The outof-
reactor test rig and the special devices for evaluation of the nuclear fuel
mechanical resistance performance at dynamic impact load, using light water at
representative parameters (pressure, temperature and flow rate) for CANDU 6
reactor operating conditions, is described.
This paper describes the original improvements implemented and
practically applied to mechanical resistance of carrier fuel bundle validation
technology. Some results and conclusions are presented at the end.
