Physical launch of the WWR-M reactor in the branch of Physical-Technical Institute of AS of the USSR in Gatchina took place on the 29th of December in 1959. However the first work on nuclear spectroscopy was carried out before the reactor was launched; namely, gamma-radiation was measured of short-lived isomeric nucleus with lifetime of some tens of minutes produced by irradiation in the reacto...

Nuclear reactors have, during the first twenty years of their existence, achieved an impressive safety record, possibly exceeding that of any comparable industry. As revealed in apaper byHenriB. Smets of the European Nuclear Energy Agency, there have been recorded during this period of time but six fatalities and less than 30 persons seriously irradiated from reactor accidents. Three of the fat...

Increasing the distance from which an antineutrino detector is capable of monitoring the operation of a registered reactor, or discovering a clandestine reactor, strengthens the Non-Proliferation of Nuclear Weapons Treaty. This report presents calculations of the reactor antineutrino interactions, from both quasi-elastic neutrino-proton scattering and elastic neutrino-electron scattering, in a ...

The Daya Bay reactor antineutrino experiment is designed to make a precision measurement of the neutrino mixing angle θ13, and recently made the definitive discovery of its nonzero value. It utilizes a set of eight, functionally identical antineutrino detectors to measure the reactor flux and spectrum at baselines of ∼ 300 2000m from the Daya Bay and Ling Ao Nuclear Power Plants. The Daya Bay a...
