含氚废水是重水堆产生的放射性废水之一,氚水与普通水的物理,化学性质一样,要从放射性水中除去氚是很困难的。经初步实验,用水泥的水化作用固化含氚废水是有效的办法。模拟含氚废水,采用425~#矿渣硅酸盐水泥,经混合(水/灰为0.3—0.7)制成的水泥固化体,其抗压强度均大于98×10~6Pa。以石膏粉作添加剂,克服表面泌水,用沥
Tritium-containing wastewater is one of the radioactive waste water produced by heavy water reactors. Tritiated water, like the physical and chemical properties of ordinary water, is very difficult to remove tritium from radioactive water. After a preliminary experiment, using cement hydration curing tritium-containing wastewater is an effective way. Simulation of tritium-containing wastewater, the use of 425 ~ # slag Portland cement, mixed (water / ash 0.3-0.7) made of cement cured body, the compressive strength were greater than 98 × 10 ~ 6Pa. To gypsum powder as additive to overcome the surface bleeding, with Lek
