I, INTRODUCTION s
The NUSPSC TRANSPIX System is a mobile filtration /
demineralization system designed to process all of the liquid radwaste at a nuclear power station or to serve as a I backup for installed in-plant systems. The system I
decontaminates wastewater reliably, efficiently and safely, in compliance with all applicable state and federal , ;
regulations. The system is designed, fabricated and
,li operated in compliance with the applicable guidelines of NRC Regulatory Guide 1.143, the waste form requirements of 10 CFR 61 and disposal site regulations.
This document presents specifications and data for the system and major components and describes system operation. It also describes the training to which NUSPSC technicians are subjected and the Quality Assurance program under which TRANSFIX Systems are built and operated.
Finally, this document describes operational experience at six nuclear facilities in the United States.
II. SYSTEM SPECIFICATIONS
- The brochure attached as Enclosure (1) provides general specifications and data, including plant interface requirements for the IRANSFIX System.
A. Performance Criteria ,
The TRANSFIX System decontaminates radioactive waste-water by passing it through vessels containing filtration media and ion exchange resins. The system is designed to process wastewater at flow rates of 20 to 50 gallons per minute through as many as six vessels connected in series. Decontamination factors of 102 to 104 are achieved to allow, if necessary, release of the water to rhe environment without dilution in accordance with 10 CFR 20 requirements.
~-
4 NUSPSC ccn previda eithsr disposcble vascala m;ds cf carbon steel or nondisposable, stainless-steel vessels with resin sluicing capability. The use of disposable vessels eliminates concern with sluicing con-s, "
taminated resins. The disposable vessels have been sized to fit ' four into a 14-170 shipping cask, the standard radwaste shipping cask for - the nuclear power industry. ;
I When the capacity to remove radioactive material is exhausted, the disposable vessels are-dewatered in accordance with disposal site regulations. To ensure total compliance with burial site criteria, the TRANSFIX dewatering system is designed to remove all free or pourable liquids from the vessels. After dewatering, the vessels are loaded into a 14-170 cask, if radiation levels require, and shipped to a low-level radwaste burial site for ultimate disposal.
B. Reliability Reliability. is a key consideration in the system design. The system was designed with an " inherent reliability through simplicity" philosophy. Power plant operations may be restricted if station waste collection tanks are full and waste cannot be processed.
The TRANSFIX _ system requires minimal maintenance and NUSPSC technicians are trained to perform all repairs required to keep the system operating. Components needing repairs beyond the technician's capability are simply replaced and returned to the NUS Process Services maintenance facility. ,

C. Damign Criterin
- 1. Proceaa Piping - All TRANSFIX" procsas piping is designed,' fabricated and tested in accordance with
- ANSI E31.1. - All stainless materials are used in system piping and, where practical, in the * ,
selection of piping components, such as valves gauges, pumps, etc. Thus corrosion which could af fect the system integrity is minimized. The-I waste processing lines are nominally 1 1/2 inch h in diameter and are designed such that radioactive
- material will not collect in low points or crevices.
- 2. Welding - Welding of piping is performed by welders and procedures qualified to ASME Section IX.
System piping is designed for an operating pressure of 150 psig and is hydrotested at 225 psig (1.5 times the operating pressure) for a minimum of 30 minutes in accordance with ANSI B31.1.
- 3. Vessels - All TRANSFIX" filtration and ion exchange vessels are pressure vessels which are designed, f abricated and tested in accordance with ASME Section VIII. The vessels have a design pressure of 150 psig and are hydrotested to 225 psig. A pressure relief is provided on the Control & Sample Panel as required by Sectior. VIII to protect the f system in the event an overpressure condition occurs.
- 4. Hoses - Hoses with quick-connect end-fittings are used to connect system piping units and vessels.
l All hoses are compatible with the radwaste water I
environment and have a minimum operating pressure equal to that of the system pressure (150 psig).
The hoses are hydrotested af ter fabrication to ensure the integrity of the end-fittings and the absence of defects in the hose materials. The hoses are selected to be resistant to the effects of abrasion and abuse during operations.
t
- 5. ElGctricnl - All cyctOn olGetical conponsnto Cr3 colseted cnd inctolled in cccordance with tha National Electric Code (NEC). Motors are totally enclosed, fan cooled types suitable for both' indoor and outdoor applications. Motor and process .
controls are mounted in National Electric Manufacturers Association (NEMA) Type 4 enclosures, designed for indoor or outdoor use. NEMA Type 4 enclosures are designed to meet hosedown, dust, 1 external icing and rust-resistance tests.
D. Radiation Safety TRANSFIX is designed to minimize personnel exposure to radiation in accordance with NRC Regulatory Guide 8.8 (ALARA). The system is designed to be operated remotely and lead shielding is provided to attenuate radiation from the filtration and ion exchange vessels.
In addition, filtration / ion exchange is inherently effective in minimizing radiation exposures. TRANSFIX concentrates radioactive materials in the ion exchange resins which are removed when the vessels are removed from the system.
III. COMPONENT DESCRIPTIONS The TRANSFIX System is composed of the waste processing system, which includes the Plant Connection Skid, the Control & Sample Panel and the process vessels, and the dewatering system. Piping and instrumentation diagrams (P&ID's) for the processing and dewatering systems are presented in Enclosures (2) and (3) respectively. The major components are described in the following paragraphs.
A. Process Control Equipment The process control equipment consists of the Plant Connection Skid (PCS) and the three sections of the Control & Sample Panel (CSP).
Th2 PCS 10 tha interfcca betwasn th2 ctat.an redw2 cts system and cupport corv'ic 2 cnd th2 TRANS?IX" Systca.
Waste is pumped from the plant to the PCS which contains process valving and service conr ctions for electrical power, compressed air and ser" Ice water .
(noncontaminated). The PCS also contains flow meters and a waste totalizer. A centrifugal pump is installed ;
to boost the waste supply pressure as required to maintain the system design flow rates of 20-50 gpm. I This pump can be bypassed if the station pump can provide sufficient pressure to the inlet of the TRANSFIX System.
From the PCS, the waste is directed by hose to the Control & Sample Panel (CSP) which provides valving and hose connections to the filtration and ion exchange process vessels. Pressure gauges to monitor the inlet and outlet pressure of each vessel are located on the CSP. The process flow is mimicked on the panel face to assist the system operator in operating the system safely. A vent line and a pressure relief valve, as required by ASME Section VIII, are also provided on the panel. A sample sink, located at one end of the panel, provides a separate sample point for the inlet and outlet of each vessel thus preventing cross-contamination of samples.
B. Filtration and Ion Exchange Vessels At the heart of the TRANSFIX" System are the vessels containing the media which remove the radioactive material from the waste stream. The vessel fabrication drawing is attached as Enclosure (4).
The TRANSFIX" filtration and ion exchange vessels are disposable pressure vessels which are designed, f abricated and tested in accordance with the ASME Boiler and Pressure Vessel Code,Section VIII. The vessels are constructed of carbon steel, have a design pressure of 150 psig and are hydrotested to 225 psig.
s
- Icn sxchtngsro contcining entien racins h va an intorict protectiva conting to resict corrosiva acid attack.
The standard ion exchangers contain 23 cubic feet of ,
resin or filtration media and have a disposal volume of 29.3 cubic feet. This provides a volumetric efficiency as defined by the resin volume divided by the disposal volume of 78.54. In addition, ion exchanger inlet and outlet' distributors have been designed to provide a uniform flow profile through the vessels, thereby allowing nearly complete utilization of ion exchange resin capacity. Thus, volumetric efficiency is very high and provides maximum concentration of radioactive material for the specific disposal volume.
C. Shielding Process shields designed for use with the TRANSPIX System pressure vessels minimize the radiation exposures of operating technicians in accordance with ALARA guidelines. The process shields are open ended, right circular cylinders constructed of lead with a
. rugged steel skin to provide maximum shielding capability in a minimum amount of. space and to facilitate ease of handling and transport around the power plant. The cylinder shields are located in the process area and the vessels placed into the shields.
Th2 shields are 38 inches in diameter, have an overall height of 72 inches and a weight of approximately 7500 pounds. The wall thickness provides the equivalent of 2 inches of lead in attenuating gamma radiation. The fabrication drawing for the process shields is attached as Enclosure (5).
i D. Dewatering System The TRANSFIX" Dewatering System is a skid-mounted system designed for removing free water from
! TRANSFIX" pressure vessels. The system uses a
[ blower to pull heated air through the vessel to strip and remove free water. The process is described
- moro_ fully in 83cticn IV.F. Th3 piping and instru-CGntction diggram (P&ID) for'th3 TRANSFIX d2wctcring system is presented as Enclosure (3).
The. performance of the system was tested in dewatering ,
TRANSFIX vessels to free-standing water criteria specified by 10 CFR 61 and the low-level radioactive waste disposal sites. Tests were performed with both bead-type ion exchange resin and activated carbon.
I In the testing, a test vessel loaded with non-radioactive ion exchange resin or activated carbon was filled with water. The vessel was dewatered in accordance with the process described . The drain plug was then removed from the test vessel to measure the volume of free water remaining in the vessel. In several of the tests, the test vessel was transported in a truck over the highway for over 120 miles. prior to draining to simulate transportation ' conditions. s The test results demonstrated the effectiveness of the dewatering system in eliminating all free water from TRANSFIX vessels. The testing results have been submitted to and approved by the State of South Carolina Department of Health and Environmental Control.
IV. OPERATIONAL DESCRIPTION All TRANSFIX System operations are performed in accordance with approved operating procedures.
A. System Assembly The system components are assembled in a processing area specified by the power plant. The location selected is based on many factors including space availability, access to the waste source, access to shipping areas and background radiation levels. The i
icad precoco chioldo which weigh 7500 poundo scch cro j lif ted and moved into picce using the chield lif ting I slings and a fork truck or overhead crane. The three sections of the Control & Sample Panel (CSP) are then placed approximately 24" from the shields and the Plant ,
l Connection Skid is placed within 10 feet of the CSP.
Vessels, which weigh approximately 2000 pounds and are filled with the appropriate ion exchange media, are then placed in the shields. System hoses are then 1
connected and all cam-and-groove quick-connects are secured to prevent inadvertant disconnection. The dewatering skid must also be placed in an area where the TRANSFIX vessels will be dewatered af ter ex-haustion. Enclosure (1) contains photographs of a typical TRANSFIX installation at an operating power station.
B. Waste Processing Prior to initiation of waste processing, a valve lineup is performed, with inlet and outlet isolation valves opened for vessels through which waste will be processed. Bypass valves are opened for vessels which will be bypassed during waste processing. The system is then leak tested and any leaks repaired prior to waste processing.
The NUSPSC technician notifies the power station operator that the TRANSFIX System is ready for processing. The station operator makes the lineup to pump waste to the TRANSFIX System and direct decontaminated waste to the station monitor tanks.
When the waste transfer pumps have been started, the NUSPSC technician throttles the flow rate to establish a waste flow rate of 20-40 gpm. If the plant supply pressure is insuf ficient to achieve the desired flow rate, the PCS booster pump is started to increase the system inlet pressure and flow rate. The booster pump is protected against damage from loss of waste flow with a low-pressure trip switch. The pump is also tripped on high pressure (135 psig) in case the pump

The system is secured by turning off the booster pump .
(if on) and notifying the plant operator to secure waste supply to the system and the monitor tank lineup. System valves are then shut for protection against leaks during system shutdown. g C. Chemistry Analysis i System performance is monitored by analysis of grab samples obtained from the inlet and outlet of each vessel in service. The NUSPSC technician performs pH and conductivity analyses and provides samples to the plant chemistry personnel for isotopic analysis. The activity loading of each vessel is calculated using the analyses and the volume of waste processed. -
D. Resin / Filter Media Selection Deep-bed filtration using activated carbon is normally used upstream of the ion exchangers. Activated carbon
,. performs well in removing particulates, such as activated corrosion products, and organic contaminants such as oils and other organic chemicals commonly used in power stations.
Following the filter vessel (s) are normally two cation exchangers containing strong-acid gel resin in the hydrogen form. The cation resins remove the largest :
portion of radioactive material in the waste stream, primarily radioactive cobalt and cesium.
Normally downstream of the cation resins is a vessel containing anion resin and the last vessel in series containing a mixed-bed resin. The anion resin is a
_g.
ctrong-beco gol rocin in hydroxida fora which becomes saturated with boric acid (when present in the waste stream) soon af ter being placed in service.
Decontamination capability' is not af fected, however, as -
the weak boric acid is displaced by the stronger acids in the waste stream. Radioactive iodine is the primary nuclide removed by anion exchangers. The last vessel in service serves as a polisher and contains a mixture g
of the cation and anion resins described earlier.
Another anion resin is of ten used in place of the mixed resin in the polishing vessel. The resin is a macroreticular, strong-based resin in the hydroxide form. The exchange capacity of this particular resin is relatively low, 0.5 meq/ml versus 1.1 meq/ml for a gel resin. The primary function, however, is not ion exchange but filtration of colloidal materials such as cobalt which may not be easily filterable or removed by ion exchange. If decon-tamination f actors begin to decrease for the TRANSFIX System, due to leakage of cobalt, the macroreticular resin may be used to remove the cobalt.
E. Vessel Removal Conductivity and pH measurements provide information regarding the remaining capacity of the vessels in service. This information is used in conjunction with isotopic analyses to determine when vessels are to be removed.
When using redundant cation vessels, the upstream vessel will become exhausted first. The exhausted vessel is then removed from service and the following vessel " moved up" in the process flow path by exchanging hoses. A new vessel is then placed in the backup position, thereby ensuring that older resins are
- exhausted first and that full-capacity new resins are used in a polishing position.
- k. - - - - - - .- --
i F. Dewatering When a vessel is removed from . service, it is blown down initially with service air to remove 'the bulk of the water. Inlet and outlet hoses are then connected -
between the dewatering skid and the vessel, which may be located in another shield for dewatering. The blower and heater, which heats air to approximately 150*F, are started. The suction created by the blower pulls the heated air into the vessel inlet and water-I laden air from the vessel outlet to the dewatering skid. The water is then separated from the air by a coalescing filter and collected in a 15-gallon tank.
The air is filtered through a high-efficiency filter prior to entering the blower. The air
-discharged from the blower may be released to the process area or, if desired, directed to a monitored HVAC system. In the numerous dewatering operations performed with TRANSFIX vessels, no airborne activity has ever been detected.
The volume of water collected in the tank is monitored periodically during the dewatering procedure. When no increase in the water level is observed during a dewatering cycle, all free water has been removed from the vessel and the procedure is terminated. A process control program with detailed procedural instructions is followed during actual dewatering activities.
V. PERSONNEL TRAINING Technicians assigned to field projects are trained and qualified in accordance with the NUSPSC procedure AD-011 entitled, "Pield Technician Training." The program is designed to ensure that technicians have the training and experience necessary to assure that technicians carry out their dutiesin a proper and safe manner. The program reflects a progression in skills from
'Tschnicien-III (entry-level, ralstively little sxperienca)
. to Technician-II (fully qualified for equipment operations)
'to Technician I (fully qualified for equipment setup, operation and supervision). The overall qualification program is divided into four -major areas described in the followingLparagraphs:
A. Pre-employment Review - The technician's academic credentials and previous work experience are verified.
The required security checks are completed.
B. General Employment Training - The technician completes a core' training program on Health Physics, Quality Assurance, Industrial Safety and NUS Process Services administrative instructions.
C. Technical Qualification checklist - This is a progres-sive checklist used to qualify the technician for equipment qualifications. It includes in-depth famili-arization with equipment operating and maintenance procedures and actual equipment operation under qualified supervision. Log-keeping and administrative items are also covered.
D. Technician Certification - At each level of qualifi-cation, the technician is certified by the appropriate operations manager. This certification is a final subjective analysis of the technician's capabilities to assume the applicable technician position and level of certification. Technicians are recertified annually as part of the technician's annual performance evaluation.
A copy of the " Field Technician Training" procedure and the technician certification document are available for review upon request prior to the technician's assignment to the station.
~ VI. QUALITY ASSURANCE A. NUSPSC Quality Assurance-Program The NUS Process Services Corporation Quality Assurance
. Program was established to provide assurance that the design, fabrication, testing and use of processing materials and equipment is accomplished under strict quality assurance requirements, which conform to the extent practicable with the guidelines provided in the U.S. Nuclear Regulatory Commission's Regulatory Guide 1.143. The NUSPSC Quality Assurance Manual defines the program established by NUSPSC to support the applicable sections of Regulatory Guide 1.143 and its referenced documents. This program complies with the requirements of 10 CPR 50, Appendix B and has been successfully audited by NUS and utility quality assurance groups.
It should also be noted that all process control programs which assure that waste products are acceptable to particular burial sites fall under the NUS Process Services QA Program. For example, process control programs related to resin dewatering or waste solidification are backed up with a-data package which provides the assurance that performance of the procedures will result in a product meeting regulatory criteria.
NUS Process Services Corporation has an NRC approved QA Program complying with the requirements.of 10 CFR 71, Subpart H, entitled " Quality Assurance," Regulatory f
Guide 7.10 entitled, " Establishing Quality Assurance Programs for Packaging Used in the Transport of Radioactive Material," and 10 CFR 50 Appendix B.

VII. OPERATING EXPERIENCE Since 1982, over 7,000,000 gallons of radioactive wastewater has been processed by TRANSFIX Systems at six -
facilities in the United States. Table 1 summarizes the actual processing experience with TRANSFIX.
As indicated in the table, the TRANSFIX services provided l at Toledo Edison's Davis-Besse, New York Power Authority's Indian Point III and Florida Power Corporation's Crystal River stations have been full-time applications in which TRANSFIX has processed all of the radioactive wastewater generated at these facilities. The installed plant waste evaporators were not used at all during the periods of TRANSFIX service.
Waste activities vary considerably between the plants but are typically 10-4 to 10-2 microcuries/cc. Effluent activities are typically 10-5 to 10-6 microcuries/cc to less than minimum detectable activity levels (MDA).

HOW DOES TRANSFIX WORK?
TR ANSFIX Service decontaminates radwaste water by passing it through vessels con-taining filtration media and ion exchange resins. We provide either disposable vessels made of carbon steel or nondisposable, stainless-steel vessels with resin sluicing capability. When the capability to remove radioactive material is exhausted. disposable vessels are dewatered or solidified in situ and then shipped to a low-level radwaste disposal site. In both cases. the resulting end product contains zero free-standing water WHY SO MANY and complies with all federal and state disposal regulations. All vessels are fabricated NUCLEAR UTILITIES in compliance with Section Vill of the ASME Boiler and Pressure Vessel Code.
