本标准提供了指导，并规定了确定压水堆MTC的标准。ANSI/ANS-19.6.1-2011（R2016）中介绍了热零功率（HZP）条件下反应性等温温度系数（ITC）的测量。因此，本标准涉及HZP的ITC计算以及功率下MTC的计算和测量。本标准仅涉及压水堆中MTC的计算和测量，因为这是目前美国唯一需要测量MTC的动力反应堆类型。

This standard provides guidance and specifies criteria for determining the MTC in PWRs. Measurement of the isothermal temperature coefficient of reactivity (ITC) at hot-zero-power (HZP) conditions is covered in ANSI/ANS-19.6.1-2011 (R2016). This standard therefore addresses the calculation of the ITC at HZP and the calculation and measurement of the MTC at power. This standard addresses the calculation and measurement of the MTC only in PWRs because that is the only type of power reactor currently sited in the United States for which measurement of the MTC is required.
