Nuclear Power Applications

H3D® products are perfectly suited to the nuclear-power industry. Our systems are used at over 75% of US nuclear power plants as well as other plants worldwide. Through cooperative development with the nuclear-power community over the past 8 years, many applications have been explored. A few of our favorites are shown below.

Verify the Adequacy of Temporary Shielding

H400 with shield wall
  • Determine whether or not shield is effective
  • Verify shield reduced radiation to safe levels or below that of another source
  • Search for gaps in shield
  • Recommended series: H or P

Co-60 with and without shield

Waste & Hot Spot Characterization

Characterize a barrel
  • Fast identification decreases scan time
  • Find direction and character of sources
  • Localize without exposing operator to high-radiation field
Characterize a spill
  • Quickly characterize waste drums
  • Recommended series: A, H, or P

Monitoring Contamination in a Pipe

Characterize a pipe
  • Quickly characterize sources in pipes
  • Fast identification of source buildup
  • Provides real-time ratios and isotopics
Characterize a pipe
  • Replaces need for chemistry samples
  • Quickly view distribution of sources along pipes
  • Recommended series: H, P, or S

Cargo inspection
  • Quickly locate where in container needs shielding
  • Ensure cargo meets shipping and receiving requirements
  • Scan for radioactive contamination
  • Fast imaging allows easy preparation of shipments

Site Surveys

  • Locate and characterize sources inside buildings, vehicles, containers, etc.
  • Assess threat level prior to entry
  • Recommended series: A or H
A series with valves

Contamination Control

  • Ensure contamination stays in designated areas
  • Characterize contamination
  • Recommended series: A, P, or H
