The current regulations for nuclear power plants focus on light water reactors (LWRs), and as such they may not be properly applied to non-LWR reactors such as Generation IV Reactors. For instance, there is no plant state comparable to core damage in pebble bed reactors [1]. As a result, the surrogate safety goal based on core-damage frequency (CDF), as being applied to LWRs in many countries d...

Nuclear reactor pressure vessels are often required regular inspection and maintenance in order to ensure the safety of the reactors. Failing to carry out proper maintenance could cause severe casualty. The usual way of carrying out inspection in these hazardous environments is using long reach fixed base manipulators. However, these manipulators suffer from low payload capacity and relatively ...

Calibration neutron fields have been developed at KAERI (Korea Atomic Energy Research Institute) to study the responses of commonly used neutron survey meters in the presence of fast neutrons of energy around 10 MeV. The neutron fields were produced by using neutrons from the (241)Am-Be sources held in a graphite pile and a DT neutron generator. The spectral details and the ambient dose equival...
