Tc-99m is produced from Mo-99 decay. Global demand for Tc-99m is expected to grow at an average annual rate of 3 ¿ 8 %. Therefore we need to increase the total production of Mo-99. Mo-99 is produced mainly by irradiating U-235 target fission in a nuclear reactor. Mo-99 is also created in the reactor fuel, but is not usually taken. Uranium enrichment dropping from ¿90% to ¿19.8% demands modifications on process operations to compensate for the resulting loss in output. The dropping of uranium enrichment is due to nuclear non-proliferation. Mo-99 production in the aqueous homogeneous reactor (AHR) offers an alternative method, because all of the Mo-99 can be extracted from the reactor fuel solution. Fresh fuel reactor solution consists of Uranyl Nitrate dissolved in water We propose a new design of AHR through the MCNP 4C and ORIGEN 2.2 computer code to simulate AHR. We analyze the output of MCNP 4C and ORIGEN 2.2 as a base to design AHR as Mo-99 production system.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659646430\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659646430","offer_id":39467466031197,"sku":"9783659646430","price":35.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ca5fd82d-dda4-41b5-8b11-c8f1785f6ebe.jpg?v=1773725800","url":"https:\/\/shop.autorenwelt.de\/products\/mo-99-production-analysis-of-ahr-using-mcnp-and-origen-computer-code-von-arif-isnaeni","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
