Radiological Dose Assessment

Chapter 4 Each year the potential radiological dose to the public that is attributable to operations and effluents from the West Valley Demonstration Project (the WVDP or Project) is assessed to verify that no individual could possibly have received a dose exceeding the limits established by the regulatory agencies. The results of these conservative dose calculations demonstrate that the potent...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Determination of radiological map of radionuclides distribution in soils ‎around of Shazand oil power plant

In this study, 34 soil samples were collected from the east of the Shazand power plant to the  Arak city, with a length of 25 km. The specific activities of radionuclides of 226Ra, 232Th, 40K, and 137Cs were determined using gamma-ray spectrometry method. Gamma-ray spectra registered to employ high purity germanium (HPGe) detector with 30% relative efficiency. Specific activities of correspondi...

Aging and Life Management System of Reactor Pressure Vessel

Reactor pressure vessel (RPV), the only key component that can not be replaced in nuclear power plants (NPPs), is the main barrier against the radioactive leakage. The lifetime of NPPs is dependent heavily on the life of RPV, and thus, the aging and life research on a RPV is a key factor in determining the life extension of NPPs. The purpose of this paper is to introduce an aging and life manag...
