The major parts of the TRIGA-LASER experiment for collinear laser spectroscopy on exotic fission products from the TRIGA research reactor [1] are now installed and are currently being commissioned. Besides the exploration of unknown ground in the nuclear chart with respect to spins, moments and charge radii, the experiment is the prototype of the the LaSpec experiment [2] at FAIR, GSI and will ...

The Heatpipe Power System (HI%) is a near-te~ low-cost, space fission power system that has been under development at Los Alamos National Laborato~ (LANL) for 5 years. The goal of the HPS project is to devise an attractive space fission system that can be developed quickly and affordably. The primary ways of doing this are by using existing technology and by designing the system for inexpensive...

The aim of this study is to examine a magnetohydrodynamic (MHD) power generation system for the space applications using a nuclear fission reactor as the heat source. This MHD system uses He/Xe mixed gas as coolant instead of alkali-metal-seeded inert gas. The interrelation between the specific heat of the coolant and the mass flow rate was examined. When the specific heat decreases due to incr...

The feasibility of a new approach of laser fusion in plasma without implosion has been proposed and is discussed using an intense laser. The cross section of the nuclear reaction is increased by enhancing the penetrability of nuclei through the Coulomb barrier. In this approach, an intense laser field of more than 100 PW was required to distort the Coulomb barrier to obtain enough penetrability...

S? An impact test was conducted on a 1119 pound 2 foot diameter sphere 05 <f model at the Holloman Sled Track in Alamogordo, New Mexico, This test is part of a study to determine the feasibility of containing the fission products of a mobile reactor in the event of an impact,, The model simulated the reactor core, energy absorbing gamma shielding, neutron shielding and the containment vessel. I...

The contribution describes the new measuring and protection system of the VR-1 training reactor. The measuring and protection system upgrade is an integral part of the reactor I&C upgrade. The new measuring and protection system of the VR-1 reactor consists of the operational power measuring and the independent power protection systems. Both systems measure the reactor power and power rate, ini...

In nuclear reactor design, the most fundamental task is to follow the neutron distribution as a function of space, direction, energy and time, in order to maintain and control the nuclear fission chain reaction. The fundamental equation governing the average behaviour of neutrons is given by the linear form of Boltzmann transport equation, which is an integro-differential equation. The core sim...

The utilization of clean energy is a matter of primary importance for sustainable development as well as a vital approach for solving worldwide energy-related issues. If the low utilization rate of nuclear fuel, nuclear proliferation, and insufficient nuclear safety can be solved, nuclear fission energy could be used as a sustainable and low-carbon clean energy form for thousands of years, prov...
