Abstract: Response Surface Methodology (RSM) is introduced to optimize the control rod positions in a pressurized water reactor (PWR) core. The widely used 3D-IAEA benchmark problem is selected as the typical PWR core and the neutron flux field is solved. Besides, some additional thermal parameters are assumed to obtain the temperature distribution. Then the total and local entropy production i...

The source of all liquid, gaseous and solid radioactive waste in the pressure water reactor (PWR) nuclear power plant (NPP) originate from leakage of fission products out of the fuel rods into the primary coolant and neutron activation of materials within and around the primary coolant system and reactor vessel. The source term design used to determine the concentrations of radionuclides in the...

In this paper, the transmutation of TRUs of the DUPIC (Direct Use of Spent PWR Fuel in CANDU) spent fuel has been studied with the HYPER system, which is an LBE-cooled ADS. The DUPIC concept is a synergistic combination of PWRs and CANDUs, in which PWR spent fuels are directly reutilized in CANDU reactors after a very simple re-fabrication process. In the DUPICHYPER fuel cycle, TRUs are recover...

I knew my PWR 1 course, “Rhetoric, Social Media, and Virtual Worlds,” would attract remarkable students. After all, what would better suit freshmen attending a University in the heart of Silicon Valley than a course focused on the relationship between rhetoric and new frontiers of electronic life? I took it for granted that these remarkable students, whoever they might turn out to be, would be ...

This study investigates actinide burning in a standard lattice PWR. It assumes that after the first loading of depleted uranium, plutonium and minor actinides, only the fission products are removed and only depleted uranium and the plutonium/minor actinide mixture are added. The relative concentrations of plutonium and minor actinide feed are always maintained the same as PWR discharge fuel aft...

A systematic study on long-lived fission products (LLFPs) transmutation has been performed with the aim of devising an optimal strategy for their transmutation in critical or subcritical reactor systems and evaluating impacts on the geologic repository. First, 99Tc and 129I were confirmed to have highest transmutation priorities in terms of transmutability and long-term radiological risk reduct...

There has been a lot of interest in generating electricity using nuclear energy recently. This is due to the features such source energy. The main part system reactor core, especially most widely used Pressurized Water Reactor (PWR). hottest system; security risks and economic possibilities must be considered. Controlling this can increase efficiency power systems. study presents dynamic model ...

Anesthesia for mice is commonly performed through the injection of parenteral agents via the intraperitoneal (IP) route. Variability in anesthetic sensitivities has been noted in mice resulting in inconsistencies in anesthetic depth and/or mortality. Anesthetic protocols that improve consistency and safety are needed. The objectives of this study were to assess the effects of intraperitoneal (I...

Flash photolysis studies have shown that the membrane lipid environment strongly influences the ability of rhodopsin to form the key metarhodopsin II intermediate. Here we have used plasmon-waveguide resonance (PWR) spectroscopy, an optical method sensitive to both mass and conformation, to probe the effects of lipid composition on conformational changes of rhodopsin induced by light and due to...
