Operation
Ø
Operator dose is acceptable
·
Projected annual dose must be < 150 mr for operation and maintenance of
unit
Ø
Start up, run and shut down time is acceptable
·
Project manpower required to run unit for one year. Compare to operation of other RW systems.
Ø
Monitoring and operating devices
·
Access to valves, indicators, etc does not present a safety or ALARA
concern.
Ø
Sampling
·
All sample points shall be obtained in an installed sample sink.
Membrane
Ø
Should process 5,000 gallons without requiring a flush
Ø
Evaluate flushing procedure
·
Amount of water used does not increase processing load
Ø
Biofouling control
·
Before and after membrane DP should be equal, if not project membrane life. Lifetime should be > 3 years
·
Amount of water used does not increase processing load
·
Method for chemical cleaning of membrane is acceptable to RW personnel
Permeate Flow
Ø
Should average > 6 gpm for each membrane while processing 5,000 gallons
of wastewater.
SCS Loading
Ø
Process a minimum of 5,000 gallons without requiring solids removal
Ø
Project curie & isotopic loading for full storage container
·
Use Radman to determine shipping class
·
Project system run time to meet burial requirements
·
Determine number of shipments required to dispose of waste each fuel cycle
·
Determine if cost of waste disposal is within budget
Ø
Project annual dose required for change outs
·
Projected annual dose must be < 150 mr for operation and maintenance of
unit
Ø
Evaluate flushing procedure
·
Amount of water used does not increase processing load
Demin Loading
Ø
Project amount of water that can be processed before bed is expired
Ø
Project curie & isotopic loading for each expired bed
·
Use Radman to determine shipping class
·
Project each bed's run time to meet burial requirements
·
Determine number of shipments required to dispose of waste each fuel cycle
·
Determine if cost of waste disposal is within budget
Ø
Project annual dose required for change outs
·
Projected annual dose must be < 150 mr for operation and maintenance of
unit
Ø
Determine maximum acceptable conductivity for system operation
·
Develop action plan to attain required levels
Effluents
Ø
Whole body dose <1.5E-4 mrem/100,000 gallons (0.03 mrem/year / 200
batches)
Ø
Organ dose <5.0E-4 mrem/100,000 gallons (0.1 mrem/year / 200 batches)
Ø
Curies released: <1.25E-3 curies/100,000 gallons (0.25curies/year / 200
batches)
Other Consideration
Ø
Determine if one demineralizer configuration can be used for all water
sources
Ø
Determine if ALF demineralizer system can be used with ultra-filtration unit
during outage
Ø
Evaluate processing secondary water for pri-sec leak
·
Ultra-filtration fits needs of established plans without evaporator
operation
Ø
Dose rates outside of building are acceptable
·
No accessible areas > 2 mr/hr
