Calculated estimation of explosion pressure for uranium nitrogen aerosol

Calculated estimation of explosion pressure for uranium nitrogen aerosol.

Sokolov I. P.

The analysis of the methods recommended in the regulatory document for calculation of excessive explosion pressure was carried out. A number of precision reducing simplifications were noted during calculation formulas justification, which reduce the accuracy of determining the values of excessive explosion pressure for combustible dusts.
The comparative analysis of maximum explosion pressure was carried out for aerosol pyrophoric materials used in chemical processing in nuclear fuel cycle facilities. The standard reaction heat effects for oxidation of pyrophoric materials in the air were calculated. The correlation dependences between maximum explosion pressures, reaction heat effects, concentration of pyrophoric materials particles in the air were determined.
Values of maximum explosion pressure and corresponding concentration of uranium nitrogen particles, which is the primary component of the nitrogen fuel, were estimated. Values of excessive explosion pressure of uranium nitrogen aerosol as a function of its mass increase and distance from the epicenter of the explosion were estimated.
