Neutron background of composite low-enriched uranium fuel of the IVG.1M research reactor
نویسندگان
چکیده
IVG.1M is a research pressurized water reactor designed to use high-enriched fuel. As part of the core conversion program, will be switched new low-enriched composite uranium Further operation determined by availability fresh fuel replace after next campaign and possibility ensuring safe storage irradiated spent nuclear (SNF) unloaded from core. The SNF conditions are assessed in terms radiation safety. Radiation safety achieved, first all, solving problems protection against γ-radiation, while neutron radiation, as rule, not considered due its significantly lower intensity compared γ-radiation. for reactor, which characterized set elements with low medium atomic masses, on (α, n) reaction possible, assessment component necessary procedure ensure storage. authors article propose calculating characteristics also estimate n)-component. results useful selecting transportation technologies well providing scientific justification using control burnup. was carried out verified computational codes MCNP5 Sources-4C, high-precision experimental EXFOR ENDSF data, evaluated data libraries.

Implementation of neutron radiography in the MNSR Low Power Research Reactor
Neutron radiography is an unique, advanced and useful non-destructive test method in various industries and researches. Nuclear reactors are powerful and stable neutron sources for the neutron radiography system. In this research, the MNSR research reactor has been used as a neutron source for a neutron radiography system, and its neutron beam parameters have been evaluated. Also, using the dir...
متن کاملCurrent Studies of Conversion of Ghana Research Reactor Core to Low Enriched Uranium
The core conversion studies of the Ghana Research Reactor Core started in 2006 and with the objective of designing an LEU core with similar operational capabilities as the original HEU core and with acceptable safety margins under both normal and accident conditions. Steadystate studies for converting the Ghana MNSR facility from HEU to LEU core have been performed using the PLTEMP/ANL V4.1 cod...
متن کاملTwo Methods for Converting Iran’s IR-40 Reactor to Use Low-Enriched-Uranium Fuel to Improve Proliferation Resistance After Startup
This article demonstrates the feasibility of converting Iran’s 40MWt heavy-water research reactor at Arak (the IR-40) to use low-enriched uranium fuel in order to slow the production of weapon-usable plutonium. Two methods are proposed, and both retain identical power density, thermal-hydraulic, and safety profiles as the original design and require no physical alteration of the core. They can ...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
