Nuclear Process Chemistry at Hanford
Hosted by U.S. EPA - Region 10

The principal objectives of this course are to help and assist students to learn the following subjects:
  • Radiological and radiochemistry fundamentals,
  • Reactor Physics, e.g., N-Reactor,
  • Data Quality Objectives (DQO) process, especially on using radiochemical data,
  • Properties of Irradiated Fuel, (e.g., K-Basin spent fuel),
  • Chemical properties of Hanford Tank Waste, and
  • Recent developments in the field of Radiological fuel and its potential application in radio-analytical chemistry field.
