Blaine Construction Corp.

Scope Of Work

 Spallation Neutron Source (SNS) is an accelerator-based neutron source that is built on an 80-acre  adjacent to Oak Ridge National Laboratory  Oak Ridge, Tennessee. This one--a-kind  provides  most intense pulsed neutron beams in  world for scientific research  industrial .

Blaine ’s participation   SNS  included    nine  over a six year period. These include the Front End /LINAC,  Ring Tunnel /HEBT/RTBT,  Target , Beam Lines 13 & 14,  Central Exhaust ,  CHL/RF Cryo ,  Central Laboratory      Center  Nanophase  Sciences.

 Ring Tunnel installation comprised  1,900 LF radius cast--place concrete tunnel, foundations for 5’ thick foundations  walls for inactive beam dumps. Also included was  5’ thick basement foundation for  Injection Dump. Also included was  20’ x 20’ Injection Dump Beam Vault which was lined with .750” carbon steel plate  a stainless lined tank vault.

 Target  included installation  some   most sophisticated equipment   world.   had to be closed  to allow for all trades to  prior to  equipment erection. A removable rolling roof section was designed to allow for     Target to be accessed while maintaining  enclosure. This required that all lifting be in  blind  by radio communication. Blaine performed over 1,000 lifts in excess  20,000 lbs, 100 lifts  excess  50,000 lbs  50 lifts  excess  100,000 lbs. This was without a single incident. Heavy weight concrete was utilized in  Target monolith  hot cell walls up to 14’ thick  elevated slabs to 5’ thick.  aggregate for this concrete is barged from Brazil,  batched at a cost  $690.00 per cuyd. Due to  weight, 260 lbs per cuft, only four yards can be hauled by a ready mix truck. Extensive form  was required to support  concrete placements. Within  same walls, imbeds weighing as much as 80,000 lbs had to be held within .0001 inch. Grouting was accomplished on most   equipment utilizing a grout that contained ground up engine blocks as an aggregate, weighed 290 lbs per cuft  at  cost  $1,600 per cuyd.
