'. 1. PURPOSE

  • A simplified functional diagram is shown in Figure 1. The Process Control Program for Shoreham Nuclear Power Station Unit 1 (SNPS-1) provides assurance of consistent quality waste product which is acceptable for shipment and burial by:

- Providing assurance that various waste types produced at SNPS will satisfactorily solidify.

- Providing a method by which sample batch solidification of liquid wastes (evaporator bottoms) or other wet solids may be performed to check process parameters for assurance of satisfactory solidification.

Providing maximum activity limits for different waste classes allowed for burial at disposal sites.

Providing reasonable assurance that dewatered waste products have less than 0.5 percent freestanding water by volume if packaged in something other than a high integrity container (HIC), or less than 1 percent freestanding water if packaged in a HIC.

2. SCOPE Boundary conditions (in the form of process parameters for the waste solidification system) were established within the scope of this Process Control Program such that operation within these limits gives assurance that solidification is complete. Boundary conditions for solidification were determined by chemical tests conducted with typical constituents in the liquid waste streams. These boundary conditions establish measurable physical parameters such as chemical content of the liquid waste being solidified (pH, oil, glycol, citric acid concent, etc.), chemical quality of solidification agents and liquid waste to solidification agent ratios. A boundary matrix of these physical parameters was established. The appropriate waste to solidification ratio is determined by chemically analyzing the liquid or " wet solid" waste streams via plant operating procedures and comparing the results with the established boundary matrix for each type of waste to be solidified.

3. SOLIDIFI'ATION C SYSTEM PROCESS CONTROL 3.1 SOLIDIFICATION SYSTEM DESCRIPTION l

The radioactive waste solidification system provides a complete system to package either radioactive evaporator bottoms (regenerant chemicals and floor drain concentrates) or resins / sludges for disposal.

The radioactive waste solidification system mixes separate feeds of slurried or concentrated radioactive waste and dry cement in a small-volume continuous mixer.

Normal operation of the system includes direct filling of dry masonry cement into the cement storage silo from a bulk cement truck and transfer of a process quantity to the cement batch bin. Waste flows are fixed by preset metering pumps. Flows are also monitored by tachometers installed on the control panel. The resin / sludge is processed from the waste dewatering tank and evaporator bottoms are processed from the evaporator bottoms system.

Cement and evaporator bottoms or resin / sludge are introduced.into the mixer / feeder unit for thorough mixing and discharge into the container to be filled. The small-volume continuous mixer limits the surface contact of the wet cement and also limits the quantity of wet cement in the system at any time. A manual handcrank is provided to permit emptying the mixer / feeder by the operator in case of power loss or equipment malfunction.

Flush water connections are provided inside the mixer / feeder to remove cement residue. The cement-bearing flush water is collected in an empty container and incorporated into the following cement batch.

Functional controls sequence entire operations and interlocks minimize unsafe conditions or operator error. Safety features include:

Filling cannot take place unless the fill pipe is properly inserted into the container fill opening.

  • An ultrasonic level sensor, and timer monitor waste level in the container to prevent overflowing. Cement-bearing flush water cannot be discharged unless a receptacle is in place.

The process control program and plant operating procedures must be strictly followed, however, to ensure correct solidification.

3.1.1 System Testing Thorough bench testing and full scale testing of typical materials will be performed to verify that disposal criteria will be met.

3.2 SAMPLING AND TEST REQUIREMENTS Prior to solidification of a batch, a sample must be obtained and chemically analyzed to determine appropriate waste / cement ratios.

The " Waste Packaging Process Control Form" is then completed and signed by the Radiochemistry Engineer or designee.

s Solidification of a batch begins after a sample has been obtained and chemically analyzed (solidification tested if necessary). The " Waste Packaging Process Control Form" is then completed and signed by the Chief Radiation Chemist or a designee.

If the results of the sample chemical analysis indicate that the waste batch chemistry fails to fall within the solidification test boundaries, the Waste Packaging Process Control Form cannot be completed until new sample solidification tests are run to establish appropriate cement / waste ratios.

Sample solidification is performed in accordance with a controlled plant operating procedure:

  • Liquids are considered as the evaporator concentrates. _ Prior to solidification of each batch of liquids, radioisotopic and chemical analysis sampling is perfomed in accordance with controlled plant operating procedures:

SP 72.002.18 - Radwaste Solidification Sampling SP 78.051.28 - Liquid Sample Gamma Spectral Analysis SP 78.030.30 - PH Determination 3.2.2 Wet Solids 4

Wet solids consist of spent resins and reactor water clean up sludge.

Prior to solidification of each batch of wet solids, radioisotopic and chemical analysis sampling is perfomed in accordance with control-led plant operating procedures:

SP 72.002.18 - Radwaste Solidification Sampling SP 78.051.28 - Liquid Sample, Gamma Spectral Analysis SP 78.030.35 - Solids Determination Sample' solidification tests were performed at SNPS-1 to determine boundary conditions for solidification.

3.3 SAMPLE SOLIDIFICATION TESTS 3.3.1 Liquids Liquid solidification bench tests were based en the two evaporator concentrate streams:

18 percent (weight) sodium sulfate expected from liquid waste i

evaporator 25 percent (weight) sodium sulfate expected from regenerant l chemical evaporator.

3.3.2 let Solids Bench tested resin wastes consisted of Ecodex precoat material and bead resin to be used at SNPS-1. Tests were performed on Ecodex precoat material and bead resins. It is anticipated full scale i testing will indicate a specific amount of " free" water above the

! settled solids volume is necessary to ensure proper solidification

! and waste / cement paste processing consistency.

3.3.3 Test Results The results of the bench tests indicate that good solidification with no freestanding water can be achieved at pH>5 by maintaining the fol-lowing weight / cement (W/C) ratios:

3.4 SOLIDIFICATION SYSTEM OPERATION The SNPS-1 controlled plant operating procedures, SP 23.713.01-Solid Radwaste System, and SP 23.719.01-Liquid Radwaste Evaporator Bottoms are followed to assure that equipment performance and operation con-sistently produce acceptable burial products.

3.5 DISPOSAL OF FILTER CARTRIDGES Solids wastes, such as filter cartridges, solidified samples or other radioactive debris will be immobilized in concrete used to solidify evaporator bottoms wastes in accordance with plant operating pro-cedures SP (later) (Filter Cartridge Disposal), and SP 23.713.01, Solid Radwaste System. Resin-cement mixtures will not be used for this purpose because of the relatively high activity levels asso-ciated with resin wastes.

All solids are placed within an open-mesh metal basket located in the approximate center of the liner. The basket is suspended off the bottom so that the concrete mixture will totally surround the wastes in the basket. Liners that contain solid objects are specifically identified.

4. RADWASTE FILTER SYSTEM PROCESS CONTROL 4.1 RADWASTE FILTER SYSTEM DESCRIPTION The radwaste filter system is used to process the following combined liquid radwaste streams which result from operation of the plant:

Low conductivity equipment drains

- Low conductivity wastes from the condensate demineralizer regeneration systems Ultrasonic resin cleaner backwash Decanted liquid from the phase separator to spent resin tank

- Blowdown from the reactor water cleanup, residual heat removal, and fuel pool cooling and cleanup The radwaste filter units are vertically mounted with horizontal filter discs stacked on an axially located hollow shaft. The filter assembly is spun to remove the precoat and filter residue cakes from the filter discs.

The complete filtering cycle is fully automated and controlled from the Radwaste Filter Panel Board. The precoated filter receives input from the liquid waste feed tank. At a preset condition such as high pressure drop across the filter, maximum cake thickness attained, or preestablished time interval, input from the liquid waste feed tank is discontinued. The cake is air dried, discharged, and the cycle repeated.

The filter assembly is designed for air drying the filter cake and for discharging the dry filter cake into a waste shipping container.

4.2 SYSTEM TESTING Full scale testing will be performed to verify that disposal criteria are met.

4.3 PROCESS OPERATION Controlled plant operating procedure S.P. 23.710.01 - Low Conductivity Liquid Raduaste System, is strictly followed to assure that equipment performance and operation consistently produce dry products.

4.4 DEWATERING PROCEDURE Dewatering liners ensure an acceptable filter cake product with less than 0.5 percent freestanding water in accordance with controlled plant operating procedure S.P. (later) (Dewatering Filter Cake).

Filter media less than IpCi/cc by waste volume and less than 0.5 percent freestanding water can be dewatered in carbon steel containers.

4.5 ACTIVITY LIMITS Waste activity will be sampled per SP 72.002.18 - Radwaste Solidifi-cation Sampling and analyzed per SP 78.051.28 - Liquid Sample, Gamma Spectral Analysis in accordance with classification limits as defined in Appendix B.

5. FLOOR DRAIN FILTER PROCESS CONTROL 5.1 FLOOR DRAIN FILTER SYSTEM DESCRIPTION The floor drain filter system processes the liquid radwaste resulting from operation and maintenance of the station and consists of efflu-ents from the floor land laundry drains.

The filter is a horizontal traveling screen type equipped with air drying prior to filter cake discharge.

The filter cycle is fully automated. Upon an initiating signal, the precoated filter receives wastes from the feed tank. At a preset condition such as high pressure drop across the filter for a pre-established time interval, input from the feed tank and the body feed tank are discontinued. The cake is air-dried, discharged, and the cycle repeated. This sequence continues until it is either manually or automatically terminated. Automatic termination is by a low level signal from the liquid waste feed tank.

The filter assembly is designed for air drying the filter cake and air-aided discharge of the cake (without backflushing) into a ship-ping container.

5.2 SYSTEM TESTING Full scale tests will be performed to verify that disposal criteria are met.

5.3 PROCESS OPERATION Controlled plant operating procedure S.P. 23.711.01 - High Conductivity Liquid Radwaste System, is strictly followed to assure that equipment i performance a.nd operation consistently produce dry burial products.

l 5.4 DEWATERING PROCEDURE Dewatering liners ensure an acceptable filter cake product with less than 0.5 percent freestanding water in accordance with a controlled plant operating procedure S.P. (later) (Dewatering Filter Cake).

. SAMPLE TESTS -

Samples were prepared at SNPS-1 of 18 percent sodium sulfate, 25 percent (by weight) of sodium sulfate, bead resin and powdered resin (Ecodex) at a pH range of 4-10 and with waste to cement (W/C) ratios of 0.8-1.3 (by volume). Testa at SNPS-1 have shown that for 18 percent (by weight) samples of sodium sulfate solidification is possible at a pH range of 4-10 and a W/C ratio of 1.0. Samples of 25 percent (by weight) sodium sulfate can be solidified at a pH range of 4-10 and a W/C ratio of 0.9-1.1 with the most economical W/C ratio of 1.1.

Ecodex and bead resin tested at pH values greater than 5 at W/C ratios of 0.8 to 1.3 produced a freestanding monolith with no free-standing water.

Additional samples of the previous listed sludges were taken con-taining such contaminents as oil, glycol, and citric acid at pH values greater than 5 and W/C ratios of 1.1 to 1.3. In each case, upon solidification, a freestanding monolith with no freestanding water was produced. Additional bench testing may expand the baseline W/C ratio data given.
