Low-Level Liquid Waste Confinement

associated cooling system. Agitation of tank contents should be
provided, when necessary, to control waste temperature.
Double-walled piping, multi-pipe encasements, and double-walled tanks
should be considered to establish the primary and secondary
confinement boundaries in underground portions of high-level liquid
waste systems. Provisions should be made to detect leakage from the
primary confinement to the interspace.
Installation of spare pipelines between transfer points should be
considered.
Process and waste storage vessels should be vented through appropriate
treatment systems that control the release of radioactive material in gaseous
effluents, ensuring these releases are ALARA. Design of these systems
should consider the following:
Off-gas should be suitably pretreated upstream of off-gas treatment
equipment to remove or reduce the concentration of chemicals that may
adversely affect system operation.
The venting system should prevent overpressure or vacuum conditions
from occurring within vessels.
The venting system should prevent the build-up of hydrogen from
radiolysis.
Tank overflows should be directed to collection systems.
Integrity of the primary confinement boundary should be determined by some
or all of the following measures:
vessel inventory monitoring (e.g., liquid level sensors);
on-line leakage monitoring for the interspace of double-walled vessels
(e.g., airborne activity monitors, sump level sensors, conductivity cells);
I-79
