Advantages of this reactor include easy loading and removal of catalyst, a high conversion with large throughput, tight temperature control, no hot spots in the bed, uniform catalyst distribution, and longer catalyst life. 5420 Tubular Reactor with Touchscreen Control, Apparatus for Vapor Pressure Determination. [1], The PARR-I Reactor was supplied by the United States government in 1965 under the Atoms for Peace program. Applications of fluidized bed reactors include but are not limited to Fisher-Tropsch synthesis, catalytic cracking of hydrocarbons and related high molecular weight petroleum fractions. The Pakistan Atomic Research Reactor or (PARR) are two nuclear research reactors and two other experimental neutron sources located in the PINSTECH Laboratory, Nilore, Islamabad, Pakistan. 4; pg. The reactor was made critical on 31 October 1991 under the supervision of Dr. Ishfaq Ahmad and Dr. Iqbal Hussain Qureshi, and attained power level of 10 MW on 7 May 1992.

The PARR-II Reactor's design is similar to Miniature neutron source reactor (MNSR) and SLOWPOKE reactor. The test yield of a nuclear devices was reported to be 12–40 kt. This is advantageous when the solids bed must be removed and replaced frequently. Vol. [12], In 1961, the United States Government led the establishment of ICF-based Fusion power experimental source near at Nilore, before the establishment of PINSTECH Institute. The desirability of using fluidized beds is dependent on achieving good mixing between the solids and the suspending fluid. Same as the first reactor, the reactor is designed to use the High Enrich Uranium (HEU) fuel. This site uses cookies to ensure that we give you the best experience on our website. Compared to packed bed, a fluidized bed has notable advantages such as better control of temperature, no hot spot in the bed, uniform catalyst distribution and longer life of the catalyst. The reactor was indigenously designed by the PAEC as the chairman Munir Ahmad Khan and his team of engineers and scientists also led the construction of the reactor. [13], Location of Pakistan Atomic Research Reactor. The second stage, consisting of various laboratories, workshop, library and auditorium, became operational in 1974. The new Tubular Reactor with Touchscreen Control from Parr was designed with researchers in mind and offers a compact footprint, easy set-up and integrated touchscreen control, all at a budget-friendly price. In the first stage, reactor building and ancillary facilities were completed with the reactor becoming critical on 21 December 1965. Fluidized beds have been significantly utilized in chemical processes, in which parameters such as diffusion or heat transfer are the major design parameters. Mastermind of the MRF

The plant was completed in 1981 and cold reprocessing tests for producing plutonium took place at New Labs in 1986. It was officially commissioned in December 1963 and left service in January 1967. The distinguishing feature of a fluidized bed reactor is that the bed of solid particles or catalyst is supported by an up flow of gas. Recent additions to this line have included new sizes, new temperature and pressure combinations and new self-sealing closures, all designed to provide convenient vessels for laboratory procedures that must be performed under pressure at […] Parr Instrument Company Parr Tubular Reactors use continuous reactant feed, a variety of heating and product handling options, with automation and data collection options. [3] The first reactor went critical on 21 December 1965 under the supervision of Hafeez Qureshi, Dr. M. N. Qazi, Naeem Ahmad Khan and Saleem Rana. The PARR-II Reactor is an indigenously designed and constructed reactor owned by the Pakistan Atomic Energy Commission. Gasification in a fluidized bed can be utilized to convert coal, biomass and other waste materials into synthesis gas. (800) 872-7720. [12], The particle facility is designed to implantation of 42+Mo,51+Sn, and46+Pb ions into steel, friction can be reduced by up to ~50%. Parr tubular reactors are especially appropriate where high pressures, high temperatures, or exotic alloy materials of construction are required. However, to ensure the continuity of the nuclear fuel, PARR-I was converted to use the ~20% Low-enriched uranium (LEU) from the 235U in October 1991[4]
