At first glance, it may appear similar to SQL. However, MDX is a completely new language. SQL was designed to query dimensional data structures, called tables, where data are organized in rows and columns. In OLAP, data are organized around multiple measures, dimensions, hierarchies, and levels.
Yield (in megatons) of the B83 nuclear weapon, which is the largest nuclear weapon currently in the U.S. stockpile. 1.24. Shortest range (in miles) of a U.S. nuclear shell. Known as the âDavy Crockett,â the W54 weapon, a small nuclear warhead with a weight of 51 pounds, was fired by a recoilless gun mounted on a jeep. Number of U.S. nuclear weapons used in wartime, against Hiroshima on August 6, 1945 and Nagasaki on August 9, 1945.
This report estimates how soon Iran could fuel a nuclear weapon. With its thousands of gas centrifuges, Iran now has the ability to enrich uranium to a grade suitable for use in nuclear reactors or to a higher grade suitable for use in nuclear warheads. Before using uranium in a warhead, it must be enriched to weapon-grade (90 percent or more U-235) and processed into a metallic shape sufficient to explode in a chain reaction. 2  This assessment assumes that Iran would use 16 kg of weapon-grade uranium (~90 percent U-235) in the finished core of each nuclear weapon.
