Shearon Harris Nuclear Power Plant Safety Evaluation Report Confirmator Item 29 Item The applicant has committed to provide details, as they become available, on the polymer binding system.
~Res esse:
As requested in SER Section 11.4.2, the following detailed description of the polymer binder system of the Solid Haste Processing System (SMPS) provides sufficient information for NRC review of system design and acceptability.
Pol mer/Dr Salt Solidification S stem The Polymer/Dry Salt Solidification System (P/DSSS) is designed to solidify the dry salt product generated in the Volume Reduction System (VRS) by application of a vinyl ester polymer product as a solidification agent. The polymer exists in a liquid state, and in combination with the promoter and catalyst, comprises the bulk of the three-element polymer solidification agent. The P/DSSS consists of the following subsystems; (a) Dry Product Storage and Transfer System, (b) Polymer Fill Station and Storage Tank; and (c) Polymer/Dry Salt Drumming Station (Flow Diagram CAR 2165-G-873). A copy of this drawing has been provided to the reviewer.
A. Dr Product Stora e and Transfer S stem The Dry Product Storage and Transfer System includes a small Isolation Hopper interfacing with the VRS, a large Product Storage Hopper and Gas/Solid separator, and a Fluidizing Turbine Air Blower Skid.
- 1) The Isolation Hopper (IH) functions as a surge hopper to the VRS, a dry product staging point to allow for partial temperature decay and a redundantly controlled feeder/eductor that provides air pressure and moisture isolation between the VRS and the dry product storage hopper. Physical isolation and residence time at the bottom of the IH provides for additional temperature decay.
Isolation between the VRS and P/DSSS is accomplished thru a combination of the IH that provides 4 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> reserve capacity for the VRS and a group of specifically designed valves that isolate system pressures. The VRS will operate at about 7.5 to 12 psi while the P/DSSS operates at negative 100 inches of H20 ~
is controlled by reciprocation of a metering piston that accepts material from the IH and transfers it thru a flow barrier and deposits it in a cooling chamber below the IH where it is cooled IH is by fluidization. Residence time of the material in the approximately 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, while residence time in the cooling chamber is approximately 8 minutes. At the end of this time, material is educted to the Storage Hopper.
(217NLU/ccc)
~ ~
P
The IH will accept dry product from the VRS at an operating temperature of 900'F (maximum) as a flow rate of 10 to 20 lb/hr of fines and bed material. Six heaters are installed in the IH to maintain a processing temperature of 180'P (minimum). Temperature is controlled automatically by a combination of a thermocouple and temperature indicator switch. When the IH reaches 180'P the heaters will shutdown and the hopper is ready to receive dry product from the VRS. Most of the heat carried by the dry product is transferred into the air surrounding the surge hopper by radiation and, convection. The hot air is vented to the HVAC exhaust system (equipped with charcoal and HEPA Filters) to maintain temperature in the area at 104'P.
The IH has three (3) level sensors. The Operating Level (OL) sensor works in conjunction with the OL switch to start transfer of dry product from the IH to the fluidizing chamber. The Intermediate Level (IL) sensor works in conjunction with the IL switch to cause an increase in flow rate of dry product from IH to fluidizing chamber. The High Level (HL) sensor works in conjunction with the switch to indicate that the dry product has backed up the IH to a point where it is almost at holding capacity and a shutdown of VRS system is imminent.
Major components of the Product Storage Hopper (SH) are the product hopper, Packflushable filter cell and feeder/eductor system. The SH receives dry product from the IH at a temperature less than 180'P. Residence time in the SH is more than sufficient for the temperature to decay below the limits set by the pretested solidification formula. The feeder/eductor is computer controlled to provide uniform and predictable flow from the SH to the Gas/Solid Separator directly above the downcomer of the polymer drumming station. The feed of the product is controlled at the SH slot discharge by five independently driven pneumatic vibrators.
The redundant feed system assures that the SH can be completely emptied when service is required. Peed from the SH discharge falls into an air acceleration chamber beneath the feeders, which is piped to the Gas/Solid Separator above the drum process enclosure. All air used during transfer of dry product and any residual particulate is returned to the SH via the backflushable filter mounted above it.
The SH is the optimum location for air filtration because powder located anywhere in the pneumatic system including drumming station downcomer can be returned to storage at any time.
The turbine air blower is the primary component of the dry product storage and transfer system. It provides transfer air for moving the dry product from the IH to the Gas/Solid Separator and SH, and from the storage hopper to the drumming station by virtue of the Gas/Solid Separator at the drumming station. The blower is also a component that provides return air from the Gas/Solid Separator to the filter above the SH, returning filtered air to the air stream supply (217NLU/ccc)
A heat exchanger is used to cool the air stream leaving the discharge of the turbine blower. Room air is drawn up thru the heat exchanger radiator to provide necessary cooling of the blower outlet air. The heat exchanger is mechanically connected to the plant HVAC System by ducting.
The turbine blower load limit control valve IV-901 on the blower discharge side is used to prevent motor overload condition and is monitored by the blower load limit control. The system make-up air pressure regulator (PCV-510) will maintain system pressure at or above negative 100 inches of H20. When the system pressure drops below negative 100 inches of H20, the pressure regulator will open to allow instrument air pressure to enter the system,'and raise t'e pressure above the negative 100 inches of H20 ~
The transfer system operates below atmospheric pressure and down to pressure approaching negative 3 1/2 psig, thus minimizing radioactive release from the system under both normal and upset conditions. Dynamic seals, packing and rotating or translating penetrations are ~totall absent from the radioactive portion of the system eliminating need for routine maintenance and/or replacement. Since all penetrations are statically sealed, only catastrophic failure and a particulate release to the off gas systems need be considered. The system supports two transfer modes: a) transfer from the IH to the SH and b) transfer from the SH to the Gas/Solid Separator above the drumming station. Only one transfer mode is used at a time.
Both the IH and the SH are adequately instrumented to provide pressure, high level, low level, and temperature information to the process control computer.
B. Pol mer Fill Station and Stora e Tank The Polymer Filling System performs a number of related functions:
inspection of drum and caps for structural integrity and proper thread line, long-term storage of large quantities of polymer chemicals under controlled conditions, insertion of the in-drum mixing device, application of specifically proportioned quantities of polymer to the drum, recording of drum tare weight and filled weight, drum sealing and assigning a number.
The Polymer Fill Station (PFS) includes all the equipment necessary to actually transfer the waste solidification chemicals in specified proportions from the polymer storage tank into drums. The principal items of equipment include a 5100 gallon polymer storage tank, circulating pump and flow measurement, 6 gallon promoter tank and metering pump, heat exchanger with chiller, drum weighing scale and necessary sensors and valving for process control. Circulation of polymer must'ake place at regular intervals to maximize its storage life and prevent possible polymerization within the piping and monitoring equipment. Recommended intervals of recirculation are: (a) for 10 minutes every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> the binder in the piping is recirculated, and (b) for 400 minutes every 2 weeks the entire contents of the storage tank is recirculated and sparged with air. The sparge air control system, (217NLU/ccc)
activated by the programmable controller, is used to inject 60 scfh of 65 psi air into the binder during tank recirculation. The air is introduced thru a 40 micrometer eductor element located in the binder return line.
Recirculation is controlled automatically by timers in the programmable controller as long as the PFS remains powered in the standby mode.
The circulating pump is also used to add polymer to the drum in the drum filling operational mode.
The circulating pump is driven by a two-speed motor with high speed (875 rpm) employed during recirculation and low speed (430 rpm) for drum filling.
A heat exchanger with chiller is installed in the return line to cool the recirculated polymer prior to its return to the storage tank. This prevents the temperature increase which is a normal result of the recirculating process and maintains the temperature of the binder in the storage tank within the 50 to 75'F range to maximize its storage life.
The heat exchanger is a tube type unit sized for binder flow at a range of 1.5 to 3.0 gpm. Cooling is provided by chilled 42'F water at a flow rate of 1.5-3 gpm. The heat exchanger includes a temperature actuated control valve in the influent chilled water line, which opens the water supply on demand by the programmable controller.
The promoter metering pump assembly is used to apply promoter to the polymer in the polymer mixing mainfold at a ratio of 1 part promoter to 1000 parts of polymer. The pump is a positive displacement unit driven by rotary gear from the adjacent motor assembly.
A magnetic pick-up is used to monitor pump rpm for the variable speed control. The speed control also receives a 4-20 ma signal from the binder flow indicator and based on these data, continuously adjusts motor rpm to deliver promoter at a fluctuating rate that remains in proportion to actual polymer flow.
The ventilation equipment has the required 10 cfm at negative one inch of 0
H 2. (minimum) service from the fill station areas non-radioactive ventilation system to remove potentially dangerous styrene vapors from the polymer filling station. The equipment consists of an activated charcoal filter assembly and butterfly valve. A differential pressure switch is installed around the filter to indicate when it is in need of service.
Although the primary device controlling the amount of polymer applied to each drum is the binder flow totalizer, a scale assembly has been included beneath the polymer filling station conveyor rollers to serve as a weight-activated back-up to end the drum totalizer failure.

C. Pol mer/Dr Salt Drummin Station The solidifcation process is initiated at the PFS by filling a 55 gallon drum with a controlled amount of vinyl ester polymer. A controlled ratio of polymer and promoter are mixed at the time they are metered into the 55 gallon drum. At this time, the polymer feed is stopped, the in-drum mixer is precharged with stabilized catalyst and inserted into the top of the drum, the weight of the drum is recorded, the dxum is capped and a control number is applied to the drum head.
All drum preparation and solidification agents filling operations are performed on the safe side of the shielded wall. The drum is prefilled with solidification agents and sealed. The drum is then conveyed by a conveyer to the drum pick-up point for removal by fixed bridge crane.
The crane transfers the drum to the Polymer/Dry Salt Drumming Station.
This completes the non-radiation-side chemistry process for the drumming operation. The drum is positioned inside the drumming station to engage the mixer drive and to align the seal system at the fill fill port. The drum is provided with a hole as part of the in-drum mixer such that a dust seal is obtained when the drum is positioned against the nozzle. The drumming station enclosure and fill fill nozzle are pressure controlled in such a way as to produce a differential pressure across the drum/nozzle boundary to the extent that the seal system can be continually monitored during the filling process and the leakage of air, if any, will always be from the exterior toward the interior of the drum, thus preventing contamination of the drum exterior.
At the drumming station, once the prefilled drum has been placed in the drum processing enclosure and the hatch closed, all subsequent operations, such as uncapping, filling/mixing, and recapping are performed automatically.
The drum position for capping is assured by a mechanical device which guides the cap flange into the proper position.
When in position, the capper inserts the capper collet into the cap, expands the collet with sufficient force for the cap removal, reverses direction, and turns the cap out of the drum on the same helix as the threads in the cap.
Dry salt/ash from the SH is fed at a controlled rate directly to the 55 gallon drum via the in-drum mixer which mixes the dry salt waste and the polymer until either the drum is determined to be full or the quantity of polymer is exhausted; the flow of dry salt waste materials is then automatically stopped. Process parameters including maximum mixing time is controlled by a micro processor. Maximum mixing time is based on solidification formulas.
Stabilization of the catalyst permits it to be in intimate proximity to the polymer for an indefinite time without catalysis. The catalyst is dispersed into the binder/promoter mixture during the verification phase that takes place within the drum processing enclosure during the drumming process. The three-component binder works as a solidification agent by surrounding the waste stream and physically entrapping it after (217NLU/ccc)

polymerization. Generally, there is no chemical reaction between the waste and the solidification agent as there is with cement and liquid waste. Once addition of the waste stream is complete, reaction of the solidification agent components proceeds by first gelling and finally becomming a solid block.
The polymer waste solidification process is a cross-linking reaction, which is exothermic. The exothermic reaction is not noticeable until the polymer waste mixture has gelled and begun to harden. Solidification is assured thru temperature monitoring.
The automatic drum capper is part of the drumming station and utilized for the capping and uncapping operations at the drumming station.
Upon completion of the drumming process the drum is weighed, radiation levels are recorded prior to drum removal and the drum is then transferred remotely to the drum storage area, During the drum filling process, sufficient surge capacity is available in the XH for approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of feed from the VRS. Polymer drumming time on the other hand, takes from 20 to 45 minutes.

P Shearon Harris Nuclear Power Plant Safety Evaluation Report License Condition No. 4 Item Approval of the VRS is contingent on the applicant's agreeing not to process filter sludge in it.
~Res esse:
Filter sludges will not be processed through the volume reduction system (VRS). Instead, the processing path will be that the filter sludges are sent to the waste processing decanting tanks where the excess carrying water is.
decanted and drained to the floor drain treatment system. The concentrated filter sludges will be transferred to the waste processing cement drumming stations where they will be solidified with cement in accordance with solidification procedures. This has been previously discussed with the NRC staff reviewer and agreed upon. This item should be removed as a license condition.
