摘 要：For a development procedure of an LWR fuel assembly, the accomplishment of a performance target must be verified through out-of-pile tests of a fuel assembly and its components. KAERI constructed a test facility to measure and analyze the pressure loss, the lift force, the flow induced vibration and the fretting wears as well as to verify the compatibility of difference fuel assemblies in a transient reactor core. This test facility of the fuel assemblies is named PLUTO from Performance Test Facility for Fuel Assembly Hydraulics and Vibrations. The design pressure and temperature of the PLUTO are 4 MPa, and 250 oC, and the maximum operating conditions are 3.5 MPa and 210 oC, respectively. The primary circulation loop consists of the main circulation pumps, two test sections, and an expansion tank, a main heat exchanger and auxiliary systems. Flow in the loop is provided by 4 non-seal canned motor pumps in a parallel arrangement, and maximum flow rate is 1400 m3/hr. This paper briefly introduces the PLUTO facility and reports the comprehensive verification results.
