MAGNESIA-MINERAL-SALT COMPOSITION
HIGH PROTECTED UNDERGROUND NUCLEAR POWER PLANTS
EFFECTIVE MATERIAL FOR IMMOBILIZATION OF RADIOACTIVE WASTES
Magnesia-mineral-salt composition (MMSC) is blended on the base of inexpensive and prevailing natural minerals and wastes of metallurgic production.
MMSC's characteristics significantly exceed technical requirements for materials for nuclear wastes immobilisation (state standard GOST R 51883-2002)
MMSC do not require high power inputs as at vitrification process. This parameter is similar to power inputs at concreting process
Technological equipment for MMSC production and use is similar to serial concreting equipment.
MMSC has similar basic consumer characteristics as "Sinrok" material, but the cost price is much lower
MMSC obtains high-strength, poor-porous special surface layer, with beauty non-inferior to mother-of perl
Methods of nuclear wastes immobilisation are protected by patents and certificates:

HIGH PROTECTED UNDERGROUND NUCLEAR POWER PLANTS
An idea to allocate an atomic power plant under the ground to reduce the risk of radioactive environmental pollution in case of a reactor accident appeared in the 50-es of the 20th century. A reliable shelter for a nuclear power facility and storages of spent nuclear fuel and radioactive waste against any anthropogenic
and natural external forces can be ensured by the thickness of the Earth bowels. In that case the hermetization of the underground volume that incorporates them guarantees that any radiation accident will be localized in such a volume.
This is the essence of the UNPP concept that rates above everything the public safety
and the environmental protection.
HIGH PROTECTED UNDERGROUND NUCLEAR POWER PLANTS
The competitiveness of UNPP is due to the maximum effective (up to 80 %) utilization of its thermal energy and unique radiation services, as
well as thanks to the practiced technologies of construction, operation and replacement upon expiration of service life.
The ecological advantages of atomic power engineering, characteristic of the rated operating conditions of many hundreds of NPP units, on the one hand, and the production capabilities of shipbuilding technology conversion emerged in the late 80-es, on the other hand, became a prerequisite of effective inculcation of the equipment of atomic vessel machine-building and instrument-making in commercial atomic power plants.
HIGH PROTECTED UNDERGROUND NUCLEAR POWER PLANTS
THE FOLLOWING SHIPBUIDING TECHNOLOGIES ARE APPLIED IN UNPP:
• Compactness ensured by the turnkey industrial manufacturing of atomic electric modules, which will allow allocating them under the ground for the period of operation and later withdrawing them for subsequent disposal at a plant.
• Modularity that contributes to unification of the equipment being mass produced and supplied as well as timely repaired in a centralized way at the ship-repair facilities or shipyards.
• Flexibility providing full adaptation of the plant power to any loading schedule of consumer mains.• Approbation of the applied equipment in the fleet that ensures the shortest time possible for equipping UNPP and its attractiveness
for investments.• Shock resistance of equipment that guaranties reliable operation of UNPP in any seismic region.• Universality of technologies that permits allocation of power modules both in the coastal and continental territories.
The plants allocated in mines, adits, and tunnels equally guarantee consumers an uninterruptible power supply and safety.

Social and economic status of UNPP comprises:
• high consumer qualities due to a multi-module structure of UNPP that reliably guaranties uninterruptible production of not just electric power but also marketable heating almost independently of season and transport conditions;
• possibility to install UNPP in the area with any population density due to the fact that the stability of the underground shelter for radiation hazardous elements (reactor facility, storage of SNF and RW) will not be broken under any conditions. UNPPs are invulnerable against any external natural, technogenic and anthropogenic impacts, and any internal accident with radiation hazardous elements will be Localized by a single barrier having strong structure and tight sealing preventing emission of radioactive substances into the environment.
• investments attractiveness of the project that is based upon experience of operating the prototype nuclear facilities, fast manufacturing of the electric power modules at the existing shipyards and their transportability, the industrial methods of sinking and drifting of underground areas that allow to construct and maintain the plant in any region of the planet.
• possibility to maintain the plants with the help of existing ship-repair facilities and shipyards. This makes it unnecessary to build repair-shops directly at the UNPP sites and simplifies decommissioning of UNPP, which will be limited to express substitution of spent electric power modules with the new ones.
The competitiveness of the UNPP commercial parameters based on shipbuilding technologies makes them to be a profitable branch of domestic atomic vessel machine building and instrument making.
When exporting the UNPP equipment the Russian side ensures the following:1. Training of local personnel.Dismantlement of equipment and disposal of spent nuclear fuel at its own plants
