Abstract

At the present time the direct nuclear energy conversion into optical radiation is realized in gas media in which filling of energy levels takes place in the low-temperature plasma (nuclear-excited plasma) induced by ionizing radiation. The research of optical radiation of the nuclear-excited plasma induced by products of nuclear reactions is interest for development of an alternative outlet method of energy from the nuclear reactor, creation of control and regulating bodies for parameters of nuclear reactors as well as creation of one of diagnostics of high-temperature plasma in fusion reactors. The purpose of this work was to obtain new experimental data about processes of nuclear energy conversion into optical radiation with the optimal gas media having high coefficient of nuclear energy conversion into optical radiation and also with a possibility of outlet method of energy from the nuclear reactor core. In this article, description of the reactor experimental bench (LIANA) and the experiment scheme, the irradiating ampoule device (AD) with surface source of charged particles is provided, and the procedure of reactor experiment is presented. This paper presents the results of the reactor experiments of studying the spectral-luminescent characteristics of unary noble gases (Ne, Ar, Kr, Xe) and binary Kr-Xe gas mixture in a 200–975 nm spectral range with ionization gaseous media by products of 6Li(n,α)T nuclear reaction under irradiation at research water-cooled heterogeneous reactor (the IVG.1M).

Highlights

The efficiency of converting nuclear energy into light energy depends largely on the choice of the active gaseous media excited by nuclear reaction products [1]

Summary

Introduction

The efficiency of converting nuclear energy into light energy depends largely on the choice of the active gaseous media excited by nuclear reaction products [1]. If a suitable composition of the gaseous media is found, it is possible to ensure selective level filling of impurity gas in these collisions where laser generation can be obtained [2]. Efficient excitation of the gaseous media needs isotopes interacting with neutrons in direct contact with this gaseous media. Exothermic neutron nuclear reactions such as 3Не(n,p)T, 10B(n,α)7Li and 235U(n,f)F were used to generate a nuclear-excited plasma. The Branch of Institute of Atomic Energy of National Nuclear Center of RK (Kurchatov, Kazakhstan) is currently conducting the experiments on studying the spectral-luminescent properties of a nuclear-excited plasma induced by nuclear reaction products of 6Li(n,α)T, by using surface sources of charged particles.
