In a simulated engineered barrier system consisting of a simulated HLW glass doped with 237Np, a compacted bentonite and water under reducing conditions, leaching of Np from the glass and diffusion of the leached Np through the bentonite were measure

Autor: Shizuo Kikkawa, Hiroshi Kamizono, Yoshihiro Togashi, Shingo Tashiro
Publikováno v: Journal of the American Ceramic Society. 72:1438-1441
The authors discuss the volatility of /sup 137/Cs and /sup 106/Ru from borosilicate glass containing actual high-level waste measured in an almost closed stainless-steel canister. The temperature dependence of the volatility of /sup 137/Cs was close

Volatilization of Cesium from Nuclear Waste Glass in a Canister
Autor: Haruto Nakamura, Shizuo Kikkawa, Hiroshi Kamizono, Shingo Tashiro
Publikováno v: Nuclear Technology. 72:84-88
Volatilization of /sup 134/Cs from simulated high-level waste glass in a canister during several reheatings up to a maximum of 1000/sup 0/C was examined. The results showed that the temperature dependence of the amount of /sup 134/Cs suspended in the

The Void and Hole Effect in D2Moderated Reactor
Autor: Yasushi Nakai, Shizuo Kikkawa, Mitsuo Yokota, Yasuhiko Miyasaka, Osamu Sugimoto, Isao Arase, Denziro Nemoto, Kinichi Hagioya
Publikováno v: Journal of Nuclear Science and Technology. 1:11-17
The reactivity cbange due to increase in the radius of empty hole was measured in a D2O moderated reactor and some results differing from experiments with ZEEP were obtained. It can be concluded that the streaming in a hole is not so effective for re

Experiment of Bubbling Void Importance in the Core of JRR-2
Autor: Yasuhiko Miyasaka, K. Haginoya, I. Araes, D. Nemoto, Osamu Sugimoto, Yasushi Nakai, Shizuo Kikkawa
Publikováno v: Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan. 6:455-459
One of the interesting problems in the core physics of a heavy water moderated reactor is the local importance for mass void and bubbling void. We published already a paper (J. Nucl. Sci. Tech., 1, No. 1, pp. 1117) about the influence of reactivity c
