A process vessel ventilation system is being installed in a facility that houses two tanks that will process decontaminated salt solution at the Saltstone Production Facility.
AIKEN, S.C. – The EM program and its liquid waste contractor at the Savannah River Site are improving salt waste disposition work and preparing for eventual operations of the Salt Waste Processing Facility (SWPF) currently being constructed.
EM and Savannah River Remediation (SRR) are installing a process vessel ventilation system in a facility that houses salt solution receipt tanks at the Saltstone Production Facility. When operational, these tanks will receive decontaminated salt solution, which will be turned into a grout mixture and permanently disposed of in disposal units.
“The process vessel ventilation system is a vital part of the success of SRR’s liquid waste mission and an enhancement to the safety of our project,” said SWPF Project Integration Manager Keith Harp. “The system being installed has an environmental monitoring system that prevents any breakthroughs into the environment.”
The ventilation system will keep the facility housing the salt solution tanks in a negative pressure to prevent release of unwanted contamination into the environment. Outside air is pulled through the tanks by the ventilation system, which prevents buildup of hydrogen gas inside the tanks. The system is designed to filter and monitor the air from the tanks before it is released into the environment.
SRR President and Project Manager Stuart MacVean says the new system will be of great assistance to the start of SWPF.
“Not only is it going to help SWPF operations, but this new system will also improve the flexibility of current salt processing within the liquid waste facilities,” MacVean said.
The tanks will aid the Modular Caustic Side Solvent Extraction Unit as it increases production rates. This unit’s equipment takes high-activity salt solution and divides it into two waste streams. One stream, the decontaminated salt solution, is transferred to a 4,000-gallon vessel at the Saltstone Production Facility. The salt solution receipt tanks, which are scheduled to be operational in July 2015, will provide up to 120,000 gallons of space with improved ventilation.
