Nuclear Rocket Engine Reactor

This book covers the problems of theory and practice of developing core elements for a high-temperature Nuclear Rocket Engine reactor (NRER). As a concept, the problem is solved through a non-separable interrelation of the structure, properties and performance patterns of the structural elements. Due to high brittleness of materials used in a structure, on the basis of interstitial phases, i. […]

History Creation of a Nuclear Rocket Engine Reactor

The high pace of development and the high scientific and technological level of atomic power engineering achieved in the USSR in the second half of the 1950s created objective prerequisites for the construction of fundamentally new types of stationary and mobile nuclear energy reactors and facilities intended, in particular, for cosmic purposes, such as nuclear rocket engines (NREs) and small-size […]

Mechanical Properties of Fuel and Structural Materials

4.3.1 Strength of Materials at Different Loading Mode The change of loading mode from tension to bending and compression for ZrC, NbC, ZrC+NbC at the deformation rate 10-3 s-1 decreases brittle-ductile transition temperature Tb-d and rises the level of ductile deformation. The strength level of ceramics in brittle condition in most cases depends on the stress state considerably so while […]

Bearing Capacity of Elements’ HGA

7.1 Fracture Criteria of Thermally Loaded Bodies Temperature stresses inevitably appearing during the NRE operation are one of the main factors that can cause the destruction of ceramic units of HRAs [1]. In some cases, temperature stresses determine the construction features and output parameters of a device being developed and the possibility of using one material or another. Therefore, to […]
