PURPOSE The purpose of the Process Control Program is to provide reasonable assurance of the'omplete solidification of processed radioactive wastes and of the absence of free water in the processed waste product.
Details of the design or construction of the radwaste solidification system are not included.
This information may be found in the appropriate design
~
drawings for Susquehanna SES and the UNC Nuclear Industries TOPICAL REPORT for the radwaste solidification system, as referenced in section VIII.'of this document.
Process Control Program Page 4 of 14 Il. RESPONSIBILITY The.responsibility for implementation of the Process Control Program is as follows:
A.
Radwaste Supervisor (Operations)
The Radwaste Supervisor is responsible for assuring that the solidification equipment is operated in accordance with applicable plant operating procedures and the Proceds'ontrol Piogram.
The Radwaste Supervisor. is also responsible for assuiing that periodic calibrations and inspections are performed within the. schedule established by'he Process Control Program and that the'appropriate waste solidification records are generated and retained.
The Shift Supervision performs. these duties in the absence of the Radwaste Supervisor.
B.
.Chemistry Group The Chemistry Group is responsible for prescribing'the appropriate mixing ratios and approving any changes of the solidification agents, i'.e.,
cement type, sodium silicate concentration, etc.
C.
Plant Engineering'Group
'he Plant Engineering Group is responsible for reviewing and approving all changes to the. Process Control Program and the radwaste solidification system.

Process Control Program Page 5 of 14 SOLIDIFICATION VASTE STREAMS A:
Vaste Inputs to thy Radvaste Solidification System In general, radioactive waste material collected:from the Reactor,
- Turbine, and Radwaste Buildings by the Liquid and Solid Radioactive Vaste. Handling Systems is eventually routed to the waste mixing tanks of the Radwaste Solidification System.
Plant laundry wastes are normally processed and released to the
'environment,
- however, these wastes may be processed to the Radwaste Solidification System as well.
Figure 1, located in Appendix D, is a schematic diagram of the radioactive waste
'lowpaths for the Radwaste Solidification System of Susquehanna Steam Electric Station.
Inputs to the waste mixing tanks are as follows:
l.
~ Evaporator Concentrates 2.
Filter/Deminezalizer Media 3.
Vater and Chemical Additives
- l. 'vaporator Concentzates Evaporator concentrates are 'up to 25 weight/ solids solutions which consist. primarily of sodium sulfate as solids due to the regenerant chemicals used for condensate demineralizer resin regeneration.
The solids content may be less concentrated during certain operational conditions.
The evaporator concentrates will also periodically contain decontamination agents and laboratory wastes.
Laundry vastes.
may also be'resent.
2.
Filter/Demineralizer Media Filter/demineral.izer media will be added on a batch basis to the waste mixing tanks by gravity from the LRV Filte'r located
'bove each waste mixing tank.
The filter/demineralizer media is normally dewatered to approximately 50 weight.X moisture by.air drying on the LRV Filter elements, and then discharged to the waste mixing tanks.
In certain operational conditions.
the filter cake may not be air dried, but vill be discharged directly into'the waste mixing tanks following draining away of the gross water volumes.
The filter cake may consist of fouled diatomaceous earth oz powdered resin from the
" filtering of liquid waste waters or combinations of filter precoat materials and filtezed solids from dewatering slurry vastes.
The LRV Filters are typically pzecoated with clean diatomaceous earth or powdered resin pr'.< z to dewatering
e Process Control Program Page 6 of 14 slurries.
Slurries may consist of bead resins from the Radwaste Deminer'alizer and the Condensate Demineralizers (Spent Resin Tank) or of powdered resins from the Reactor Water Cleanup'and Fuel.Pool Cleanup Filter/Demineralizers (Phase Separators}.
The Phase Separators may include filter sludges from the Condensate Demineralizers and the LRW Filter's as well.
3.
Water add Chemical Additives 1
Water may be added to the waste mixing tanks to slurry the dewatered filter c'ake in the ev'ent evaporator concentrates are hot available (see section III.B.2).
Water is also used to flush the system piping and pumps after processing is complete.
A chemical'ddition funnel is pr'ovided for each waste mixing tank for waste pretreatment and system decontamination solutions as necessary.
B. 'dentification of Waste Types in Each Batch The contents of the waste mixing tank are determined and recorded
'y the following methodology.
This discussion is typical for both solidification trains.'
7 2.
pre..
(
(cf I (t'~~
The operator records the initial status of the waste mixing tank level, which would normally be 0$ or empty, on the Radwaste Solidification Data sheet, If the tank is not empty, the amount and type of material present in the tank is recorded.
cia. /A 4'gg The operator then adds li uid wa te to the waste mixing tank in order to slurry the solid wastes when.they are received from the filter discharge.
Two sources of li uid are available, either chemical liquid radwaste or condensate.
Evaporator concentrates are normally used and may be pumped from the evaporator concentrate storage tank or either of the two evaporator shells.
In the event chemical wastes are not available or are not desired, condensate would be added to the waste. mixfng tank.
The waste mixing tank level is again recorded to determine the amount of liquid added.
3.
Solid waste additions are then. made to the waste'ixing tank by batch solids discharges from the associated LRW filter.
The level in'the waste mixing tank is recorded before and after the filter discharge to determine the amount of solids added.
A typical filter precoat layer of diatomaceous earth prior to.waste filtering is about 0.15 pounds of precoat material per square foot of filter surface
- area, which is equivalent to.a uni'form precoat thickness of 3/32".
This results in about 19 gallons of solids for the Susquehanna SES
Process Control Program Page 7 of 14 LRW filters, which have a nominal surface area of 300 square feet.
As waste and filter aid material are removed by the filter, the cake thickness willbuild up to a maximum of
. 15/16".
This results in a maximum filter discharge of about 175 gallons of filter cake.
The live capacity of each waste
~ mixing tank is about 840 gallons.
The precoat material and
'the t
e of waste removed during each filter run is also recorded on t e adwaste Solidification Data Sheet.
The filter cake is dewatered on the LRW filter's horizontal elements by draining the free liquid from the filter shell.
The filter cake is normally further dewatered by blowin'g air through the LRW filter and actually drying the cake.
The air being exhausted from the filter is monitored by a.moisture detector which indicates the exhaust dew point on the LRW filter control panel.
At the end of the cake drying operation, the dew point of the exhaust air is recorded by
.- the. operator and is us'ed to determine the moisture content of the filter cake. If the filter cake is not dried by this for'ced air method, a typical value of cake moisture content'<Pc2~(
A maximum amount of solids per waste mixing tank will be determined'ased on startup experience to ensure solids loadings are not.too high for acceptable solidification and
(.
tank mixing.
Additional liquid may be added to the waste mixing tank if desired or necessary to maintain an acceptable slurr'y, with each addition to the waste mixing tank being recorded as to type of waste and the change in tank level.

. Waste Preconditioning il
'ertain wastes may require

('olidification.
Examples'of this might be evaporator concentrates with a very'low pH or'adwaste Demineralizer resins which were not fully spent..
The Chemistry Group will advise the Operat'iona Section'of any waste P'econditioning which should be done.
The.specific Solidif'ication Instructions address any preconditioning required for. predetermined waste types and include limits. for batch processing based on vendor, startup or operational experience.
P',l,)S In general, the following areas of concern will be addressed to assure satis factory solidification:

given 'to the Operations Section for normal waste processing.
.These ratios, called Solidification Instructions, are based on guidelines from the solidification system vendor (United Nuclear industries), pre-operational testing and operational'xperience at Susquehanna SES~ or laboratory-testing of non-radioactive waste specimens.
Wastes which do not meet the predetermined ranges or wastes types, that have not been addressed. in. the specific Solidification Instructions provided will.be handled on a case by case basis by'the Chemistry Group.
Satisfncdgg;g mixing ratios will be determined and forwarded to the Operations I'
c Section or alternate methods for handling the batch will.be given.
~~ /j The. Radwaste Solidification Data Sheet'is used to determine the final batch composition.
The various additions to the waste mixing tank are categorized and totalled on the data sheet.
The specific Solidification Instruction which applies to the typ'es and ran'ges of the<,~
batch of waste to be processed is determined and verified by the Radwaste Supervisor or Shift Supervisor.

forwarded to the Chemistry Group.for resolution and the batch in the waste mixing tank is placed on hold i.e.
no further additions are made
- without the approval of the Chemistry Group.
The Chemistry Group will
'esearch th'e batch and prescribe the appropriate mixing ratios which l will result in satisfactory solidification or specify alternate measures to be taken to handle the batch, e.g., dilution of the tank or addition of caustic.
After the proper mixing ratios are determined and all required preconditioning is complete, the operator adjusts the speed control potentiometers on the solidification control panel to provide the prescribed flow rates of cement,
- waste, and sodium silicate.
Thi's is done thxough the use of the most recent equipment calibration data for the various pumps and the cement rotary feed valve.
The prescribed flow r'ates, the speed. control potentiometer settings, and the identification number of all waste containers processed from that batch are recorded on the Radwaste Solidification Data Sheet.
Solidification P'roduct'quality The qualit'y of the solidification product is of prime importance.
Product quality is the key to fulfillingthe purpose of the Process Control Program, which is to provide reasonable assurance of the'omplete solidification of processed radioactive wastes and of the absence of free water in the processed waste product, as stated in Section I'.
Solidification 'is defined as the conversion of radioactive materials from liquid systems to a monolithic immobilized solid with definite volume and'hape, bounded by a stable surface of distinct outline on all si'des (free-standing).
This definition does not exclude the processing of multiple batches of waste product into a single container at different times or the placement of wet or dry filter cartridges in the solidification waste container to achieve shielding or immobilization.'atisfactory solidification is quantitatively defined as less than 0.5$ of the container volume or one gallon as free water, whichever is less'.
Pl Solidification 'product quality is assured by the use of predetermined~-+~!,'roven mixing'ratios of waste,
- cement, and sodium silicate. 'ixing ratios are, based on actual testing, done before system contamination
';~
,j'~
with radioactive mat'erials'r during operation by laboratory testing p"
using non-radioactive waste materials.
Ranges of waste properties are established which guarantee satisfactory solidification for the given mixing ratios.,
The actual waste material is compared to the established
- ranges, theieby determining the proper mixing ratios to be used to 'guarantee satisfactory solidifica'tion.

solid waste or the processed waste/cement/silicate product would result
~ in excessive radiation exposure.to plant personnel and is contrary to station ALARA (As Low As Reasonably Achievable) policies; The use of non-radioactive waste for verification of sol.idification is used as a
reasonable and adequate method for assurance of solidification produc~
quality.
Curing. Time The 'solidified product may not achieve ult'imate strength until several weeks after processing.
For the purposes of most testing,
'the product is assumed to be cured within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Some wastes may require longer curing times. 'he radwaste Solidification Instructions'will include the required curing time for each waste category to achieve satisfactory solidification.
Waste containers will not be shipped off" site. until they are adequately cured.
Handling of Unsolidified Waste Containers In the unlikely event a waste container is discovered which does not meet the criteria for satisfactory solidification, several options for '
h'andling
'the container are available. If the reason for unacceptability is excessive free water, the free wa'ter may be removed or extra cement and/or s'odium silicate may be added to solidify the.
free water.
Zf portions or.all of the product did not solidify, the waste container may be handled by the addition of solidification agents until satisfactory solidifi'cation is achieved or the waste container may be overpached by the use of a larger container filled with.
solidifaeB cement or concrete to encase the unsolalified container in a solidified capsule.'
~ N Process Control Program Page 11 of 14 V;
SOLIDIFICATION AGENT CONTROL Portland cement and sodium silicate'(Liquid form) are the two agents which are used to soli'dify the wet radioactive wastes.
A.
Procurement of Solidification Agents The agents which are used at Susquehanna SES will be purchased to the following specifications:
Portland Cement - ASTM C-150, Typ'e II Sodium Silicate - Philadelphia quartz
- Company, Weight Ratio: Si02/Na20 Percent Na20
'Percent S:02 Degrees Baume Density, lb/gal Viscosity TypeiN, oi equivalent 3.20 8.90 28.70 41.00-11.60 180.00 Portland Type I 'or V cement may be purchased if Type II is not available, with prior Chemistry approval.
Any deviations shall be approved by Chemistry Supervi'sor.
B.
Receipt Inspection Both the Portland cement and the sodium silicate will be inspected upon.
receipt to verify that the shipment being received is the correct material.
A copy. of the supplier's bill of material shall be retained and stored with the records of the waste solidifications.
C.
Periodic Inspection The sodium silicate will be sampled each time water is added to the tank to ensure the contents of the tank are at the proper concentration of.40 - 42 degrees Baume'. If the sodium siLicate is not at'the proper concentration, the Chemistry Supervisor. will advise'Operations personnel of the proper corrective action.
The sodium silicate tank will be resampled to verify the proper concentration is attained if chemical adjustment is performed.
0 Process Control Program Page 12 of 14 Vl. CALIBRATION OF SOLIDIFICATION EQUIPMENT Equipment which is adjustable and iinportant to the proper operation of the radwaste solidification system must be periodically calibrated to assure satisfactory solidification is achieved.
Calibration of most of the system must be done at reasonable intetvals to meet the objectives of the station ALARA program (As Low As Reasonably Achievable) for reducing personnel radiation exposure.
yI I
Appendix B, "Radwaste'Solidification System Calibration Requirements",
specifies the equipment which must be calibrated and the frequency of calibration.
The system pumps are calibrated annually by flow tests to account for wear of the pump stators, which are made of an elastomer.
The cement rotary feed valve is calibrated using valve speed only because wear is not. expected for this component.

.Equipment Operation
~
The Radwaste Supervisor or the Shift Supervisor supervises the operators of the radwaste solidification system.
Each operator is trained in <he operation of the system pri'.or to processing wastes.
Written procedures are provided detailing the operation of the solidification system.
Processing is normally semi-automatic
'equir'ing operator action only to initiate the process and flush modes by pushbutton and mon'itor system peiformance.
Manual operation is fully desc'ribed in'he system operating procedure.
All important injormati'on is recorded on the Radwaste Solidification Data Sheet and is initialled by the system operator.
Radwaste Solidification Data Sheets are reviewed by the Radwaste Supervisor or.his designee to ensure the process requirements were met.
I B.
Records Records o'f the types and amount of radioactive waste processed, including the Radwaste Solidification Data Shee'ts, are retained for a period 'of two years 'subsequent: to the shipment of the waste material, off-site for disposal.
The procedures and instructions for processing the wastes are also retained for the same time period.
C.
Waste Container Numbering Each waste container is.uniquely numbered on the exterior to permit indentification of the, particular waste batch and for inventory p'urposes.
The. container number is recorded on.the Radwaste Solidification Data Sheet'during the container filling step.
D.
Changes'to the Process Control Program Any changes to the Pro'cess Control Program shall be p'rovided in the Semiannual Radioactive Effluent Release Report filed with the NRC. 'll changes shall be reviewed and approved by'the Plant Operations Review Committee.
