A Comprehensive Survey on Particle Swarm Optimization Algorithm and Its Applications
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 Particle swarm optimization (PSO) is a heuristic global optimization method, proposed originally by Kennedy and Eberhart in 1995. It is now one of the most commonly used optimization techniques. This survey presented a comprehensive investigation of PSO.

Mathematical Models for Investigation of WWER-1000/320 Transients
Nuclear and Radiation Safety, 2018 The paper presents mathematical models of the reactor WWER-1000/320, which are designed to investigate non-stationary operating modes of the reactor. The models in relative state variables include a point model of neutron kinetics with six groups of delayed neutrons and models of thermal processes, gradual heat generation, change in xenon concentration.

The Use of Th in HTR: State of the Art and Implementation in Th/Pu Fuel Cycles
Science and Technology of Nuclear Installations, Volume 2009, Issue 1, 2009., 2009 Nowadays nuclear is the only greenhouse‐free source that can appreciably respond to the increasing worldwide energy demand. The use of Thorium in the nuclear energy production may offer some advantages to accomplish this task. Extensive R&D on the thorium fuel cycle has been conducted in many countries around the world.
