1983年10月30日英国温斯克尔后处理厂(B205)停产进行年修。11月10日在一班将结束时,发现水相中混有有机相和界面污物,但在交班时,没有交待此情况。结果这批废液进入了规定为盛低放液体的排放槽(B241)里。尽管操作手册规定,只有在事先分离掉有机相,并且水相中放射性小于150居里(β-γ放射性)时,才能排入排放槽。但至今不知由于什么原因,实际却未进行这一步操作。直到辐射监测器发 October 30, 1983 British Winsker post-processing plant (B205) discontinued for annual repair. At the close of the class on November 10, it was found that the organic phase and interfacial contaminants were found to be mixed in the aqueous phase, but this was not explained at the time of shift. As a result, the waste enters the discharge tank (B241), which is designated as the drop liquid. Although the operating manual states that the discharge tank can be discharged only if the organic phase is separated beforehand and the aqueous phase has a radioactivity of less than 150 Curie (β-γ radioactivity). But for now I do not know for what reason, but actually did not carry out this step. Until the radiation monitor hair
