Conventional oil sewage treatment methods can achieve satisfactory removal efficiency, but energy consumption problems during the process of oil sewage treatment are worth attention. The integration of a constructed wetland reactor and a microbial fuel cell reactor (CW-MFC) to treat oil-contaminated wastewater, compared with a microbial fuel cell reactor (MFC) alone and a constructed wetland re...

An SPND (Self-powered Neutron Detector) is commonly used for neutron detection in NPP (Nuclear Power Plant) by virtue of un-reactivity for gamma-rays. But it has a drawback, which is that it cannot detect neutrons in real time due to beta emissions (about > 48 s) after reactions between neutrons and Rh in an SPND. And Generation IV reactors such as MSR (Molten-salt reactor), SFR (Sodium-cooled ...

This paper attempts to summarize the actual problematic of reactor antineutrino energy spectra in the frame of fundamental and applied neutrino physics. Nuclear physics is an important ingredient of reactor antineutrino experiments. These experiments are motivated by neutrino oscillations, i.e. the measure of the 13 mixing angle. In 2011, after a new computation of the reactor antineutrino ener...

A roadmap for developing accelerator driven systems (ADS) in India was prepared in 2001. The first phase of the activities under the program began with the commencement of the tenth plan in 2002. This involves the development of a 10 MeV (upgradeable to 20 MeV), 30 mA proton linear accelerator, the setting up of a lead bismuth eutectic (LBE) loop for target and coolant studies and a reactor phy...

BACKGROUND This work presents an initial proposed design of a Prompt Gamma Activation Analysis (PGAA) facility to be installed at the TRIGA IPR-R1, a 60 years old research reactor of the Centre of Development of Nuclear Technology (CDTN) in Brazil. The basic characteristics of the facility and the results of the neutron flux are presented and discussed. FINDINGS The proposed design is based o...

The assumption that the shape of the epithermal neutron spectrum can be described, in any research reactor, by the 1/E1+α function is a fundamental starting point of the k0 standardization. This assumption may be questioned from a reactor physics viewpoint. The type of moderator, the existence of neutron reflectors, the additional production of (γ, n) neutrons and resonance capture by construct...

The research reactor IRT-2000 at the Institute for Nuclear Research and Nuclear Energy (INRNE) in Sofia was built and put into operation in 1961. It was temporarily shut down in 1989 for improvement. The reconstruction into IRT-200 is being carried out under the decision of the Council of Ministers of Republic of Bulgaria in 2001. The strategy for sustainable utilization considers the IRT-200 a...

Increasing economic globalization and mounting time and cost pressure on the development of new raw materials for the chemical industry as well as materials and environmental engineering constantly raise the demands on technologies to be used. Parallelization, miniaturization, and automation are the main concepts involved in increasing the rate of chemical and biological experimentation.

This paper analyzes the power loss of magnetically controlled reactor based on the basic theory of the electromagnetic field. In a variety of magnetic valve structure model as the object, physical simulation models of the reactor are built. Using Ansoft Maxwell simulation software, various magnetic valve structures of the reactor are studied by the analysis of the magnetic valve type reactor co...
