HFETR—回路水的辐解研究

本文对 HFETR 冷却剂——水的辐照分解做了细致的研究。监测了10—80MW 运行功率下氢及过氧化氢的生成量,以及同一功率状况下氢及过氧化氢随时间的变化情况、辐解量与水质的关系等.实验表明:辐解产物——氢及过氧化氢的量随功率的升高而增加,但功率提升至30MW 以后,其量变化缓慢。在同一功率状况下,自达到功率的瞬间开始,辐解量随时间迅速增加,但很快趋于稳定。反应堆在10—80MW 功率下运行,正常状况的氢含量不超过15mL/L(H_2O),过氧化氢最大为26.6ppm.

Radiolysis researeh of the Primary Circuity for HFETR

In this paper the radiolysis of reactor coolant water of HFETR was resea-rchde in detail.The amounts of hydrogen and hydrogen peroxide at power of 10 to 80 MW were determined.The amounts of hydrogen and hydrogen peroxi-de in the water and the relation between the amounts of radiolytic products with the quality of the coolant water are researched.The results of experiments shew that the amounts of radiolytic products hydrogen and hydrogen peroxide increased with the reactor power,and increased slowly after the reactor power up to 30MW,and at the reactor power level of 10 to 80MW,the amounts of hydrogen is not more than 15 mL/LH_2O,the maximum amount of hydrogen peroxide is 26.6 ppm.
