Fabrication, Pre-Irradiation Characterization and Base-Irradiation Data of Test Fuel Rod Group PK1X: The Super-Ramp Extenstion Project.

摘要

For the extension of the SUPER-RAMP Project KWU will supply three PWR test fuel rods and two additional spare rods of the same rod type denoted PK1X, which correspond to the fuel rod type PK1 used in the SUPER-RAMP Project. The PK1X rods were fabricated and characterized during fabrication in the year 1977, in parallel with the PK1 rods. The base-irradiation of both rod groups in the nuclear power plant Obrigheim (KWO) started in June, 1977. In Part A this report presents the data on fabrication and pre-irradiation characterization and in Part B the data on base-irradiation history of the PK1X rods. Since the design of these rods, the fabrication process and the most part of the materials used for rod components as well as the irradiation conditions in KWO are identical to that of the rod group PK1, only the data being particular for the PK1X rods are outlined here. 2 refs., 5 figs., 6 tabs.
