【美国《核安全》1981年11-12月号第728页报道】在三里岛核电站事故以后,几个调查小组专门研究过这次事故。这些研究普遍提出仪表需要一定的改进,特别是在如下几个方面: 1.参数的直接而清楚的测量,例如反应堆压力容器中的水位和卸压阀的位置。 2.扩大重要参数(例如堆芯热电偶和辐射监测器)的测量范围,包括运行和事故 [U.S. Nuclear Security, November-December 1981, page 728] Several investigation teams have studied the incident after the accident at Three Mile Island. These studies generally raise the need for some improvements in instrumentation, especially in the following areas: 1. A direct and clear measure of parameters, such as the water level in the reactor pressure vessel and the location of the pressure relief valve. 2. To expand the measurement range of important parameters (such as core thermocouple and radiation monitor), including operation and accident
