ULTRA-FILTRATION TEST PLAN

Operation

          Operator dose is acceptable

        Projected annual dose must be < 150 mr for operation and maintenance of unit

          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.

          Monitoring and operating devices

        Access to valves, indicators, etc does not present a safety or ALARA concern.

          Sampling

        All sample points shall be obtained in an installed sample sink.

Membrane

          Should process 5,000 gallons without requiring a flush

          Evaluate flushing procedure

        Amount of water used does not increase processing load

          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

          Should average > 6 gpm for each membrane while processing 5,000 gallons of wastewater.

SCS Loading

          Process a minimum of 5,000 gallons without requiring solids removal

          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

          Project annual dose required for change outs

        Projected annual dose must be < 150 mr for operation and maintenance of unit

          Evaluate flushing procedure

        Amount of water used does not increase processing load

Demin Loading

          Project amount of water that can be processed before bed is expired

          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

          Project annual dose required for change outs

        Projected annual dose must be < 150 mr for operation and maintenance of unit

          Determine maximum acceptable conductivity for system operation

        Develop action plan to attain required levels

Effluents

          Whole body dose <1.5E-4 mrem/100,000 gallons (0.03 mrem/year / 200 batches)

          Organ dose <5.0E-4 mrem/100,000 gallons (0.1 mrem/year / 200 batches)

          Curies released: <1.25E-3 curies/100,000 gallons (0.25curies/year / 200 batches)

Other Consideration

          Determine if one demineralizer configuration can be used for all water sources

          Determine if ALF demineralizer system can be used with ultra-filtration unit during outage

          Evaluate processing secondary water for pri-sec leak

        Ultra-filtration fits needs of established plans without evaporator operation

          Dose rates outside of building are acceptable

        No accessible areas > 2 mr/hr
