Abstract
The paper provides an overview  of technical solutions for using of heat pipes in nuclear power plants both  developed and operating. The review based on the scientific, technical and patent literature shows wide application heat pipes as heat transfer  devices. Using of them for small and super-small power plants seems to be  especially effective, because of high specific cost of plants with circulating  coolants.
  A heat pipe is a  device transferrind the heat by means of evaporation and condensation of a  coolant circulating automatically under the action of capillar or gravitation  forces. Heat pipes are used rather widely, both abroad and in Russia. The first  application of a heat pipe principle in nuclear power plants was published in  1957, even before the emergence of the term "heat pipe".
  Now, there are about 300 patents in the world  related to heat pipes application in nuclear power plants. Theare are seweral  thouthands articles on the development of nuclear reactors with heat pipes have  been published in the scientific and technical literature. 
  One should expect that fifth-generation nuclear  reactors cooled by heat pipes without any mechanisms and machines for the circulation of the coolant, as well  as without the consumption of mechanical and electrical energy, will be  appeared in this decade.
