One of the oldest research reactors was launched over forty years ago. The WWR-M reactor started operating in December, 1959 at Petersburg Nuclear Physics Institute (PNPI) in Gatchina. Ever since it has been normally operating without replacement of the tank. Russia’s concern for this reactor as a stationary neutron source was significantly increased, when many research reactors were shut down ...

Introduction One of the oldest research reactors was started some forty years ago. WWR-M reactor started operating in December 1959 at St. Petersburg Nuclear Physics Institute (PNPI) in Gatchina. Since then it has been operating normally without replacement of the tank.

The Nigeria Research Reactor-1 (NIRR-1) is the nation’s first nuclear reactor and it is sited at the Centre for Energy Research and Training, Ahmadu Bello University, Zaria, Nigeria. It is a Miniature Neutron Source Reactor (MNSR) that attained criticality on February 03, 2004 and was licensed to operate at a maximum power of 31 kW three days a week in June 01, 2004. This presentation enumerate...

This project will examine inert fuels containing ZrO2 and MgO as the inert matrix, with the relative amount of MgO varied from 30 % to 70 % in ZrO2. Reactor physics calculations will be used to examine suitable quantities of burnable poisons from the candidate elements Gd, Er, or Hf with reactor grade Pu providing the fissile component, with up to 10 % of Pu. Ceramics will be synthesized and ch...

Increasing complexity in reactor designs suggests a need to reexamine of methods applied in spent-fuel characterization. The ability to accurately predict the nuclide composition of depleted reactor fuel is important in a wide variety of applications. These applications include, but are not limited to, the design, licensing, and operation of commercial/research reactors and spent-fuel transport...
