Lead filling is a process in which lead is introduced into a container designed to contain radioactivity and/or store radioactive materials. Depending upon the container’s geometry, the lead application process can be carried out in various ways, including lining with sheet lead, lead bricks and casting molten lead.
Canada Metal is a leader in this field and its expertise is sought from the design phase through completion to ensure the feasibility and methodology of the lead filling operation.
A prime example of the company’s expertise was demonstrated when it was asked to fill several (18) vessels of different configurations with lead. Upon completion, the vessels were to be RT tested for porosity.
Two of the vessels required approximately 43,000 lbs. of lead shielding each, using a continuous pour. Canada Metal accomplished this, with zero porosity in the 7+ inches of lead filling.
In another example, the company was tasked to provide lead shielding, with the additional assurance of adhesion of the lead to the base metals of at least 50% of the “wetted surface” area. Complicating matters further, two metals were involved, each having distinct heat coefficient transfer properties. After some experimentation, Canada Metal was able to guarantee adhesion to a minimum of 75% of the wetted surface, as confirmed by Ultrasound Testing (UT).
