On the effect of the specific heat release of a mixture of radionuclides on the relative mass transported in the “self-delivery” of spent nuclear fuel mode during space burial

The issues of disposal of radioactive waste (RW) are currently one of the serious environmental challenges. One of the ways of disposal can be the space burial of radioactive waste, which reduces the pollution of the Earth. The paper considers the issues of transportation of radioactive waste, representing a mixture of isotopes of spent nuclear fuel (SNF), estimates of the mass-energy costs of SNF transportation using electric rocket engines (ERD). A variant is considered in which the transported mixture of SNF isotopes is both a payload and an energy source – “self-delivery”. The relations for calculating the relative mass of the transported SNF at various parameters are obtained.
