Abstract: the length of the refueling water tank heater (PTR heater) in the reactor refueling pool and fuel pool cooling and treatment system (PTR system) of a nuclear power plant is more than 2 meters. Limited by the site conditions and installation location, the site operation space is small, so it is impossible to use the conventional way to repair, install and reassemble the heater. According to the characteristics of the installation site of PTR heater, without changing the design parameters and dimensions of the original heater, we will soften the heater heating pipe, so that the heater heating pipe can be bent to any angle and in any way, so as to solve the problem of installation and maintenance of heater small space. The improved heater has been tested and achieved good results.<br>Key words: nuclear power plant, heater failure, flexibility<br>
