Attachment: Arak conceptual design
Fundamental Principles:
• Maximize use of the current infrastructure of original design of Arak research reactor, designated by the IAEA as IR-40, according to their respective ratings.
• Modernizing of the original design in order to be a multi-purpose research reactor comprising radio-isotope production, structural materials and fuel (pins and assembly prototypes) testing and able to conduct other neutronic experiments which demand high neutron fluxes (more than 1014).
• Using heavy water as coolant, moderator and reflector. Light water would be utilized as an annular ring around the compact new core for safety reasons if necessary.
• Around 78 fuel assemblies in a tight hexagonal grid spacing with the following preliminary characteristics will be loaded.
• Up to 3.67 percent enriched UO2, in the improved assembly design, will be used as fuel.
• Power will not exceed to 20 MWth.
• Adding different types of beam tubes to the existing beam tubes which being extended to the edge of the new compact core.
• Having one central channel in the center of the new core with passive cooling system for the purpose of structural materials and fuel pins and assembly prototypes testing with neutron•10 flux beyond 2 14, twelve in-core irradiation channels (IIC) inside the core and twelve lateral irradiation chennals (LIC) just next to the outer ring of fuel assemblies.
• The location of the in-core and lateral irradiation channels should be designed and fixed to meet the best anticipated performances.
• Consistent with relevant section of Annex 1, sibsidiary laboratories are part of the modernization project of the Arak Research Reactor. In Addition, Annex III reinforce design and construction of subsidiary laboratoties.
• The highest tolerable pressure for the first and second loop is 0.33 Mpa (at the interance of the reactor pit).
• The highest possible flow rate for coolant is 610 kg/s at the pressure of 0.33 MPa in the main piping system and 42 Kg/sec for Moderator with the same conditions.
