“…One of the main advantages of this technique is that the solid fuel is passive to the kinetics of the gaseous reactant material [22]. A method of maintaining the inherent passivity of the solid-gas interface while improving the energy transport efficiency to the laser medium is to mix the gaseous reactant material with fuel in the form of micropellets [18]. Small spherical microspheres of fissile materials ( 235 UC, 235 UO 2 , and 235 U 3 O 8 ) have been shown to be between 60 and 90 % efficient in transporting fission fragment energy to a reactant [15,19].…”

“…Initially (1980)(1981)(1982)(1983)(1984)(1985) the nuclear-pumped photolytically driven laser system research was focused on rare gas excimer fluorescers and gas photolytically driven lasers [18,32,33,69,70]. The fluorescer gas work was centered on the xenon and xenon bromide fluorescers and the xenon fluoride and iodine photolytic lasers [3,22,32,33,69,71,72].…”

This chapter discusses the design of how nuclear reactors are coupled to lasers. The design is complex in that there are many ways to interface the reactor, which serves as a neutron source, to the laser medium. There are issues with the fuel interface to the laser that includes the phase, the type of fuel, how the fuel is put into proximity to the laser medium and the potential chemical interactions of the fuel with the laser medium. The coupling of the optics to the laser medium is also an important consideration and how radiation damage may impact the optical components, structural materials and subsystems. There are also cooling and control issues as well.

Almost all experimental studies of the characteristics of nuclear-excited plasma formed by the products of nuclear reactions were performed on impulse nuclear reactors, which differ in the composition and design of the core, the duration, flux and fluence of the neutron impulse, the volume and configuration of the area for irradiation, and the impulse repetition frequency. This work presents a description of the experimental (methodical and equipment) base of the National Nuclear Center of the Republic of Kazakhstan (Kurchatov) for conducting in-pile experiments at the impulse nuclear reactor IGR. The purpose of these works is to study the spectral-luminescent and spectral-temporal characteristics of optical radiation upon excitation of gas mixtures by 6Li(n,α)3H nuclear reaction products. To conduct in-pile experiments at the IGR reactor, a new experimental facility was developed. The experimental facility functionally consists of: a gas-vacuum system, an in-pile irradiation device with lithium layer, recording and temperature control systems of the device case, and an optical radiation recording system. A technique for carrying out in-pile experiments at the impulse nuclear reactor is described. To justify the design of the irradiation device and the safety analysis of conducting reactor experiments, neutron-physical and thermophysical calculations were carried out.
