L-Area Cask Decontamination Perma-Con® System

Project Scope:

  • Project requires deconnable modular panel facility for decontamination of spent fuel shipping casks.
  • Containment of high pressure water spray and steam cleaning decon system’s airborne and effluent discharge.
  • HEPA air filtration system and liquid effluent collection system required to support project.
  • Facility capable of passing leak rate criteria and operational testing to customer requirements.

RPS designs and delivers a turn-key modular facility:

  • Deconnable modular panel containment system.
  • One module, 18’ wide x 24’ long x 12’ high, stainless steel panels.
  • Welded stainless steel drip pan floor container system with grid decking.
  • Liquid collection and pump transfer system.
  • Spent fuel cask support stand.
  • 12’ wide x 24’ long roof access opening.
  • HEPA ventilation system designed and delivered to provide 23 room volume air changes per hour and impose laminar air flow for vapor removal.
  • Facility assembled in 2 weeks.
  • Facility air leak tightness test: =<0.1 inch water column.
  • Applications engineering, radiological engineering, mechanical design.
  • Project management and cost control expertise applied.
