ROLE: General Construction

COMPLETION: December, 2005


  This project consisted of the construction of a new nuclear spent fuel storage facility, support facilities, and expansion of the Protected Area for Salem Units 1&2 and Hope Creek Unit 1 in Hancock’s Bridge, New Jersey. Included was:
  • Installation of approximately 1,400 “Soilcrete” columns, 3’ x 15’ and up to 50’ in depth. The columns were constructed by injecting a cement/slag slurry through 6 counter-rotating augers, while drilling to the appropriate depth. The structural characteristics of the completed columns are verified by extensive quality assurance checks throughout the process from the initial mixing in a batch plant to the grout injection rate and auger speed measurements. Final verification is through core sampling and laboratory testing of the completed columns. Over 11,000 tons of cement/slag was used.

  • Installation of 3 spent fuel cask pads approximately 3’ x 90’ x 260’ and incorporating 7,800 CY of concrete. The area above the soilcrete columns is filled with 3 ft of compacted engineered fill with geogrid material prior to the slab construction.

  • The pads have integral electrical and control conduit systems for thermal monitoring capability.

  • Construction of a fabrication area for staging and placing concrete in the storage container casks.

  • Installation of a new 100’x 60’ foundation for equipment and storage of the casks.

  • Construction of the Heavy Haul Path required for a crawler to move the casks from the plant and storage pad, including soil stabilization, underground utility protection, roadway improvements, turning pads, and support systems.

  • Construction of a new access roadway about 1 mile long including all site improvements, soil stabilization, drainage, paving, guide rails, signage, etc.

  • Expansion of the existing Protected Area around the spent fuel storage facility and associated Security systems including CCTV cameras, infrared, perifield, high mast lighting, fencing, vehicle barriers, etc.

  • All work performed under a nuclear QA/QC program in accordance with 10 CFR 50 Appendix B and 10 CFR 72.
