Abstract

In due time the SSC RF-IPPE exercised the scientific supervision and directly participated in the development, fabrication, space flight test and maintenance of the direct energy conversion nuclear power plants (NPP) for space application under the, BUK“ and ,,TOPAZ“ programs. We have used the acquired experience and the high technologies developed for the, BUK“ NPP with a thermoelectric conversion of thermal (nuclear) energy into electrical one in the development under the order of RAO ,,GAZPROM“ of the natural gas fired self contained thermoelectric current sources (AIT-500) and heat and electricity sources (TEP-500). These are intended for electrochemical rust protection of gas pipelines and for the electricity and heat supply to the telemetric and microwave-link systems located along the gas pipelines. Of special interest at the moment are the new developments of self contained current sources with the electrical output of -500 We1 for new gas pipelines being constructed under the projects like the, Yamal - Europe“ project. The electrochemical rust protection of gas pipe-lines laying on unsettled and non-electrified territory of arctic regions of Russia is performed by means of the so-called Cathodic Protection Stations (CPS). Accounting for a complex of rather rigid requirements imposed by arctic operating conditions, the most attractive sources of the electricity supply to the CPS are the thermoelectric heat-into-electricity converters and the generators (TEG) on their basis. This paper deals with the essential results of the development, investigation and testing of unconventional TEGs using the low-temperature bismuth-tellurium thermoelectric batteries assembled together as tubular thermoelectric batteries with a radial ring geometry built into the gas-heated thermoelectric modules, which are collected to make up either the thermoelectric plants for heat and electricity supply or the self contained power sources. One of peculiarities of these plants is the combination of the CPS proper function with a number of additional service possibilities, among them the use of natural gas directly from the high pressure gas pipeline, the remote monitoring, the utilization of heat etc.
