Legenda - "Research and development work aimed at the reduction of fuel costs for the calder hall type power station. The experimental production of vacuun melted and cast uranium alloys. Different compositions are investigated in the search for alloys having improved strengths and physical properties under the more severe irradiation conditions required for more economical reactor operation. The vacuum furnaces can also be used to develop techniques for reducing the cost of production operations such as machining. Springfields process workers jih jones and bill jonitt are seen lowering the vacuum bell over the furnace in preparation for a helting and casting."
