Project Description
This project is one of six that Parsons has completed at the Hanford Nuclear Reservation.
The 100 BC pipeline remedial action project represents the last major phase of remediation at the location of the 100 B and 100 C nuclear reactors at the Hanford Nuclear Reservation. These reactors were the first production reactors to be brought on line in the 1940s as part of the Manhattan Project.
The project entailed excavating and containerizing more than 100,000 cubic yards of low-level radioactive soil and hazardous waste and excavating more than 250,000 cubic yards of overburden soil to expose the 5 miles of single-pass, 60-in. radioactive steel and concrete reactor cooling water piping and associated structures. Pipe size reduction and concrete structure/outfall unit construction were also part this contract, along with container packaging and transportation to the staging queue. The project also included backfilling the excavations and completely restoring the site.
