31. Shipping fuel elements to the submarine fleets. 32. In the early 60's, he investigated stress phenomena in nuclear fuel elements for the UK Atomic Energy Authority. 33. It then pivoted and turned to lie horizontally on the racks of fuel elements stored in the pool. 34. Each channel held up to 4 fuel elements and extended completely through to the inside of the cylinder. 35. Since mid-1994, they have denied all licenses to civilian nuclear plants for shipping fuel elements to the submarine fleets. 36. Each fuel element is encased in extremely tough iridium metal and then embedded in high-strength blocks of heat-resistant graphite. 37. Our analysis indicated that the material came from a failed fuel element or an element prepared for research purposes. 38. The plant uses U235 ) as a raw material which is processed to produce the final MTR-type fuel elements . 39. It is then turned into a hard ceramic oxide ( UO 2 ) for assembly as reactor fuel elements . 40. Each fuel element is placed inside a thin-walled stainless steel tube along with a small amount of sodium metal.
