Minimizing Power Peaking Factor of BEAVRS-based Reactor Using Polar Bear Optimization Algorithms

چکیده

Abstract Fuel loading pattern optimization is a complex problem because there are so many possibilities for combinatorial solutions, and it will take time to try one by one. Therefore, the Polar Bear Optimization Algorithm was applied find an optimum PWR based on BEAVRS. The desired new fuel that has minimum Power Peaking Factor (PPF) value without compromising operating time. Operating proportional multiplication factor ( k eff ). These parameters usually contradictive with each other make hard solution. reactor modelled Standard Reactor Analysis Code (SRAC) 2006. pins assemblies PIJ module cell calculations. One-fourth symmetry used CITATION X-Y core done 200 populations 50 iterations. PPF selected solution should never exceed 2.0 in every burn-up step. Out of 28 best optimal had maximum 1.458 0.916 at day 760 calculated (corresponding cycle length 479 days). 27.1% lower than safety factor, same as standard been achieved.

Estimation of the Power Peaking Factor in a Nuclear Reactor Using Support Vector Machines and Uncertainty Analysis

The monitoring of detailed 3-Dimensional (3D) core power distribution is a prerequisite for the operation of nuclear power reactors to ensure that various safety limits imposed on the fuel pellets and fuel clad barriers, such as the Local Power Density (LPD) and the Departure from the Nucleate Boiling Ratio (DNBR), are not violated during the reactor’s operation. The LPD and DNBR need to be cal...

Multi-objective Optimization of a Solar Driven Combined Power and Refrigeration System Using Two Evolutionary Algorithms Based on Exergoeconomic Concept

This paper deals with a multi-objective optimization of a novel micro solar driven combined power and ejector refrigeration system (CPER). The system combines an organic Rankine cycle (ORC) with an ejector refrigeration cycle to generate electricity and cold capacity simultaneously. Major thermodynamic parameters, namely turbine inlet temperature, turbine inlet pressure, turbine back pressure, ...

The Stream Cipher Polar Bear

We propose a new stream cipher called “Polar Bear”. It combines constructions used successfully in other situations. The key initialization uses Rijndael, the steady state uses a dynamic table as in RC4 and we guarantee a long period through the use of a linear feedback shiftregister. The efficiency for short messages is better than that of RC4 while for long messages Polar Bear is about a fact...
