This analysis deals with the evaluation of the fuel burnup behavior for PWR-1150
reactor assembly by modifying with changing both, the number of fuel rod which have
burnable absorber (BA) and the percent weight of BA in each rod. The achieved resul
t
presented in this paper enables determine the suitable structure of reactor assembly
when fuel enrichment equal to 4.4%.
The GETERA 90 code was used to perform assembly burnup calculation. For
validation purposes they are compared with selected experimental data for similar
reactor.
The MCNPX and MCNP5-BETA codes were used to simulate the reaction
9Be(p,n)9B in the Syrian cyclotron,to calculate the neutron spectrum emission
from this reaction and for neutronic calculations to design of the thermal
neutron beam for thermal neutron radiography.
The MCNPX and MCNP5C codes are used to simulate the reaction
9Be(p,n)9B. The photons and neutrons intensities resulting of this reaction are
calculated as a functions of the 9Be target thickness. To calculate this intensity,
the protons with energ
y 15.0MeV and protons current 200.0μA are used. In
addition, the angular distribution of the emitted photons and neutrons from the
reaction 9Be(p,n)9B is calculated as a function of the 9Be target thickness. The
maximum value of the photons and neutrons flux is found to be at angle 00 for
thin targets. The calculated values using MCNPX of the neutrons spectrum
emission from reactions of 9Be(p,n)9B and 207Pb(p,n) is compared to
experimental values. There is a good agreement between them.
Hydrocarbon burning nowadays has a great part of the required energy consumed in the world, mainly in the transport vehicle engines, which seems to be the main source in the future. This urges us develop the fuel burning in different internal combust
ion engines according to the environmental increasing requirements nowadays. The carbon fine-dust produced is the main source of the environmental pollutants, which could be considered as
the main cause of cancer. Therefore our present paper deals with the way of carbon fine dust formation during fuel burning in engines and gives a mathematical model describing that complex method, and studying the different function affecting its formation, the aim is to find a way to develop the burning process in engines and increase its working and decrease the pollution produced.
The Sediment microbial Fuel Cell (SMFC) has been studied in terms of electrical power generation, and water treatment. With the aim to design the Sediment Microbial Fuel Cell (SMFC), the sediment was brought from the Al-sonobar River bed, where it wa
s described to indicate the organic content and nutrients in it. The cell was equipped with a surface aeration system and started working in it. Where it monitored the electrical current and water pollution indicators over time. Later the aeration mode was changed and previous measurements of electricity generation, water pollution indicators were carried out, and compared with the previous stage. Results of the first mode of aeration have shown that the greatest value for Short Circuit Current (ISC) was (0.905) mA while the greatest value for Open Circuit Voltage (VOC) was (0.390) V. While a rise in current and voltage values was observed in the second mode of aeration, in which the greatest value of Short Circuit Current was (1.240) mA, and the greatest value of open circuit voltage (0.430) V. When the circuit has been connected to an external resistance R=100 Ω, the values for current, voltage, current density and power density were (0.805) mA, (0.084) V, (3.18) mA/m2, and (0.269) mW/m2, respectively. For water analysis, an increase in pH values of 8.90 was observed. The efficiency of removing of Chemical Oxygen Demand (COD), phosphates, nitrates and Total Dissolved Salts (TDS) has also increased, reaching: 72.11%, 62.70%, 35.60%, and 30.61%, respectively.
