It is widely recognized that safety of nuclear power plants is a problem of great relevance for society. If it is not properly managed, the increase in power and complexity of the plants can lead to a catastrophic release of energy and dangerous materials and pollute the environment. To prevent this to happen, the nuclear community always put significant efforts into finding new ways to improve...

The Great East Japan Earthquake and Tsunami in 2011 led to the accident at the Fukushima Daiichi Nuclear Power Plant (1F) and subsequent meltdown of the reactor cores of Units 1, 2, and 3. The Japanese project on material accountancy technology development for fuel debris of Units 1-3 of 1F has been implemented under the roadmap, “Mid-and-long-Term Roadmap towards the Decommissioning of Fukushi...

Abstract In order to establish the variation between results in mass fractions due software implementation, as measured by k 0 -method for INAA, IAEA has organized a intercomparison. A complete set of test spectra and associated information was assembled. Efficiency curves, neutron spectrum parameters, correction factors were calculated with participating programs (k0-IPEN, k0-INRIM, k0-DALAT, ...

Following the IAEA definitions, [1], a passive component does not need any external input or energy to operate and it relies only upon natural physical laws (e.g. gravity, natural convection, conduction, etc.) and/or on inherent characteristics (properties of materials, internally stored energy, etc.) and/or ‘intelligent’ use of the energy that is inherently available in the system (e.g. decay ...
