Evaluations on power ramp data of PWR fuels by FROST and THERMOST codes

Description

Power ramp data of Mitsubishi's PWR fuel rods tested in R-2, Studsvik were analyzed by FROST and THERMOST codes. The predictions of both codes show relatively good agreement with many measurements during or after irradiation. Especially detailed behaviours of the fuel related to axial PCMI, such as rod elongation-relaxation during ramp test, are predicted successfully. Axial and radial deformations of claddings are simulated so well that calculated stresses in claddings are considered to be reliable. The ramp data used in present analyses were obtained in two joint programs with five Japanese PWR utilities (KEPCO, KYEPCO, SEPCO, HEPCO, and JAPCO). (author)
