[Global] Tri nuc hose hot spot caused by debris

[John-Joseph Michael Hertz]

Classification - Non ENEC

I have not had to do that, but here is how I would try to solve it:

  *   Agitate the hose to try and get the material into the filter, which can be controlled/manipulated under water.
  *   Assuming that’s already been tried and failed, raise the hose closer to the water surface and use a long-handled tree trimming shear. Not sure if this picture will go through, but a Walmart search found “Fiskars 8'-12' Extendable Tree Pruner with Rope-Free Design and Rotating Head”

Good morning all,
Has anyone ever had to cut a tri nuc filter system hose under water to remove a piece of highly radioactive material?  We have something lodged in the our tri nuc hose that pegged an AMP 200 at > 10000 rem/hour.
