Determination of the Ideas and Expectations of the Students Taking the Laboratory Animal Breed-ing Course towards their Clinical Skills Acquisition and their Achievements and Anxiety Levels at the end of the Application

This study aimed to determine the thoughts and expectations of the students who took laboratory animal breeding courses about clinical skill acquisition and their achievements and anxiety levels at the end of the application with a survey study. One hundred thirtyeight students participated in the survey. The questionnaire method was applied to the propositions and questions created using the State-Trait Anxiety Scale and the literature. A statistically significant difference (P&lt;0.05) was found between the students' total scores of opinions and expectations towards the practice before and after the practice course. The total score of opinion and expectation towards the application after the application lesson was found to be higher (P&lt;0.01) than the total score of opinion and expectation towards the application before the application lesson. State anxiety (P&lt;0.05) and trait anxiety total score (P&lt;0.01) were lower after the applica-tion lesson than before the application lesson. It was concluded that the applied education made a difference in the students' clinical skill acquisition and positively affected their mood.</p

Neutronic Analysis of LBE-Uranium Spallation Target Accelerator Driven System Loaded with Uranium Dioxide in TRISO Particles

This study presents the neutronic performances of fissile breeding and energy production of a gas cooled accelerator-driven system with LBE-uranium dioxide (UO2) spallation target. The accelerator-driven system is designed and optimized by considering various target materials, in terms of neutronic. Two different materials, LBE + natural UO2 and LBE + 15% enrichment UO2 are selected as target materials. The target zone is divided into two parts, one within the other; the outer part is pure LBE target part, and the inner part is UO2 target part cooled with the helium gas. Tristructural-isotropic (TRISO)-coated fuel particles, containing UO2 fuel, are embedded in a carbon matrix pebble with the packing fraction of a 29%, and the pebbles are placed in the UO2 target part and in the fuel core with the packing fraction of a 60%. The fuel core is cooled with helium that is a high-temperature coolant. The target is bombarded with the continuous beams of a 1 GeV protons to produce high-flux neutrons that enter the fuel core. The fuel core is surrounded with a graphite reflector zone serving as both effective moderation and reflection of these neutrons. Furthermore, the whole system is enclosed by boron carbide, B4C (shielding zone), to prevent the neutrons leakage out of the accelerator-driven system. The high-energy Monte Carlo code MCNPX along with the LA150 library is used for neutronic calculations. The numerical results bring out that the investigated accelerator-driven system has a high neutronic performance, from the energy production and fissile breeding points of view. Namely, it can be obtained over the thermal power of a 350 MW and produced over the fissile breeding of a 300 g/day
