The purpose of tests is experimental validation of VVER-1200 power unit operation in a daily load schedule and to work out a method of controlling and checking the operation of the equipment. A method of controlling the reactor based on the principle of localization of xenon processes in the top half of the core in combination with soft temperature control was tested. The method allows control of reactivity by changing the coolant temperature in the primary loop at the expense of steam pressure variations in an extended range in the secondary loop. The tests confirmed that VVER-1200 power units can actually operate in a daily load schedule at the end of a fuel run without actually increasing the volume of the radioactive coolant withdrawn from the primary loop.

测试的目的是对VVER-1200动力装置在每日负荷计划中的运行进行实验验证，并制定出一种控制和检查设备运行的方法。测试了一种基于氙过程在堆芯上半部局部化的原理与软温度控制相结合的控制反应器的方法。该方法允许通过改变主回路中的冷却剂温度来控制反应性，以蒸汽压力在副回路中扩展范围内的变化为代价。测试证实，VVER-1200动力单元实际上可以在燃料运行结束时按每日负荷计划运行，而无需实际增加从主回路抽出的放射性冷却剂的量。
