Analysis of JUPITER experiments
- 1. Power Reactor and Nuclear Fuel Development Corp., Tokyo (Japan)
Description
The ZPPR-9, 10 experiments were analyzed with JENDL-2B, and the following results were obtained for physics parameters. (1) k sub(eff) values were underpredicted by about 0.8%. (2) Radial dependences were observed in reaction rate C/E distributions, which had peak values near the inner core-outer core boundary. 238U(n, f) was overpredicted by more than 10% at the innermost blanket region. (3) Material reactivity worths of heavy nuclides were overpredicted by 5 to 13%, and worths of nuclides of structural materials were overpredicted by about 20%. UO2 Doppler reactivity worths were underpredicted by about 12%. (4) Sodium void reactivities were overpredicted by about 30%. (5) The average C/E value for control rod worths was 1.02 +- 0.04.
