TMI UNIT II SPENT RESIN LINER DEWATERING I.
Background
There is considerable concern in the Nuclear Industry for the shipment and disposal of radioactive waste.
Of particular note is the existence of water in shipping containers.
Licensed burial ground facilities such as in Richland, Washington and Barnwell, South Carolina require that no water be buried.
Although the precise definition of this statement has not be,en specified in terms of chemical and physical properties of matter, it is critical that all efforts be made to minimize free standing water in shipping liners.
Occurrences over the past few years has demonstrated that spent resin containers had free standing water upon arrival at burial grounds.
This is detected by puncturing containers and observing liquid spillage.
This resultu in a violation of burial ground requirements.
It is with this concern that the dewatering of resins at TMI-II has been investigated.
A dewatering program was developed with two primary objectives:
1.
To understand the mechanism by which water exists in a resin bed and confidently determine the amount of water.
1784 078 2.
To perform various tests of removing water from the bed so as to remove free standing water from a container.
~
~
These objectives would develop a decision-making process by which we would understand the presence of water in resin containers to be shipped from TMI Unit II in a dewatered state.
II.
Discussion A.
Mechanism of Water Retention One of the main reasons that resin is used in the processing of radioactive water is 'its excellent capability to cleanse this water of ionic and non-ionic impurities.
This process in~volves strong electro-chemical interaction between water impurities and resin.
Therefore, the removal of water and/or impurities from a used resin bed involves energy and/
or chemical interaction to return resin to a pure, dry state.
Various tests were performed to evaluate how best to accomplish this process without detri-mentally affecting the sorbtion of radioactivity on the resin.
When a resin liner is filled with water, water exists in two predominant states :
1.
Free standing within the liner 2.
Electro-chemically bound by resin.
k784079'
~
Table 1 shows the breakdown of water in each of these two main states.
Table 2 is the detailed calculations in support of Table 1.
Table 3 is a graphic display of the existence of water in an EPICOR Resin Liner.
Free Standing Water The 6'x6' liner used for the dewatering tests contained 518.4 gallons of free standing water.
This is typical of the 6x6 EPICOR I and II Radwaste System Liners.
This is water that exists in space above the resin and within resin interstitial void space. The amount of water within resin void space is highly dependent upon the compaction of the resin, resin type, and exhaustive level of the beads.
This water is not bound to the resin and, therefore, can be removed from a liner relatively easily.
A pump is typically used to draw or decant the water of f the bottom of the liner through the normal liner effluent lateral arrangement.
These laterals are located on the very bottom of the liner and allow water and not resin to pass through.
The sand piper pumps used for dewatering have the capability of drawing a vacuum such that water is pulled into the laterals throughout the entire cross sectional area of the liner bottom.
The laterals are specially de-signed and tested to verify this actually occurs.
6 1780 080
Water will naturally drain to the bottom of the liner and with pumping can be removed.
There-fore, with relatively a small amount of energy input, free standing water is easily removed from a liner.
It is the removal of the water that is the objective of dewatering programs.
Electro-Chemically Bound Water This water is strongly bound electro-chemically by resin beads.
The water is predominantly chemically held in the matrix of hydration.
There are 433.8 gallons of water existing in this state in he resin.
The liberation of this water is achieved by chemical or heat treatment of resias.
Introduction of large amounts of energy will overcome the bond of hydration thereby releasing this water.
However, this process will also upset the bond between resin beads and various impurities removed from processed water by the resin.
It is, the,refore, possible to liberate radio-isotopes held by resin beads.
The amount of release would be dependent upon the extent of func-tional breakdown of the resin.
Because it is un-desirable to release radio-nuclides, there is no advantage to removing the chemically bound water.
Therefore, the dewatering process should not intro-duce large amounts of energy or chemical adjustmenIt which could alter the stability of radio-nuclides.
1784 08l'
Dewatering Testing Objectives Shipping and burial requirements state that free standing water is not allowed.
Realizing this, it is the goal of any dewatering process to remove as much of the free water as possible. 'To remove any more of the water content is self-defeating for two (2) main reasons:
1.
Removal of any electro-chemically bound water could result in the liberation of radio-nuclides from a resin bed.
2.
Drying a resin bead makes the bead more mobile such that, should th'e integrity of a resin container be breached, a dry resin is more likely to mi' grate than a wet, dewatered resin bed.
Both reasons tend to defeat a basic premise of radio-active material handling, which is:
Radioactive material should be fixed to an im-mobile medium so as to concentrate it and prevent its spread.
It is with this understanding that the various de-watering tests were conducted at TMI Unit II.
It was the objective to determine how efficient various dewatering techniques were in removing the approximate 518.4 gallons of free standing water existing in the resin liner.
NBA 082
III.
Resin Liner Dewatering Tests Several dewatering tests were conducted to determine the ability to remove free standing water in liners.
Efficiency was measured in term's of percentage of free standing water removed and gallons of water re-maining in the liner.
These tests used various sources of energy input to accomplish liquid removal.
These were:
Hydraulic:
Water pumping Pneumatic:
Air drying Thermal:
Hot air injection Mechanical: Vibration during road transit Another aspect of energy testing was the length of application.
Varied time frames were also utilized to determine effectiveness. provides the re-sults of these tests.
These test results show that 1.63 gallons of free standing water still exists in a resin liner following completion of dewatering processes.
This represents 0.3%
of the total free standing' water in the resin bed.
Some other points of interest are:
1.
Road vibration liberated only 2 quarts of water more than the dewatering process employed for the test.
2.
Although the use of heat reduced the relative humidity through the bed, it had an insignifi-cant effect on overall drying effectiveness.
3.
Altering the direct 1on of the air flow through the bed reduced the liquid drainage.
It could not.
1784 083
be verified whether this action just dis-persed the water to different parts of the bed, thereby simply delaying when it might be liberated, or not.
4.
The time the bed experienced air drying appeared to have little effect on total liquid removal.
IV.
Theoretical Dewatering Verification A.
Establishing a Mathematical Model Although the tests demonstrated how much water re-mained in the liners, addi.tional studies and tests were conducted to verify the ability to predict free standing water removal.
The precise resin mix was reviewed with respect to its state of exhaustion, electrolytical charge, compaction capability and resistence of interstitial void' space.
Laboratory tests were set up to pnme the predictability and repeatability of the conditions to insure the mathematical model was' accurate and reliable.
From this thorough analysis a mathematical model was established which calculated that 312.7 gallons of water exists as free stand #.ng water within the resin bed used in the dewatering tests.
This is the amount of liquid which has to be ren.oved by the dewatering process.
B.
Field Test Verification In parallel with this effort the resin bed.used for testing underwent several more tests.
The parameter.s 178.4 084
_g-of this test are discussed in Enclosure 4.
It was
'shown that 326.8 gallons of water were removed from the resin under conditions as assumed for the mathematical model.
This included vibrating the resins, adjusting for temperature conditions, lancing the bed to liberate trapped air, and estab-lishing proper resin compaction condition.
It is extremely difficult to establish field conditions to exactly match laboratory assumed condition.
C.
Comparison of Results It was hoped that the two independent analytical and empirical results would agree within 10% since many variables existed.
However, the results show very close (within 4. 3%) agreement, which shows not only a sound understanding of water retention in a resin bed, but also confidence in the ability to predict water removal efficiencies!
V.
Moisture Absorbtion Program With the realization that a very small finite amount of the free standing water is not removed by the dewatering procedure, a program was developed to investigate alterna-tives of insuring that absolutely no water would exist in a liner upon leaving TMI and upon arrival at the burial location.
This investigation involved testing various drying agents that could be readily pumped into and mixed within an ex-hausted resin bed following dewatering.
The, basic criteria' 1784 085
-9 used for calculating these substancas were:
1.
Non-reactive to resin beads and impurities fixed on resin.
2.
Highl' moisture absorbant.
3.
Easily pumpable.
4.
Able to mix within a resin bed.
Various laboratory tests were performed on a variety of substances.
From these tests two materials were identified acceptable (one silicate and one cellulose).
Additional tests were conducted and analysis performed to determine how much absorbant material would have to be pumped into a bed to absorb a given quantity of water that might be liberated.
In this manner, knowing the amount of free standing water that might be retained.in a liner folles-ing dewatering and shipping to the burial ground (1.63 gallons), a given amount of absorbant material could be added to eliminate the free standing state.
Also, to be conservative, a greater than necessary amount of material could be added to absorb any water that could be produced from an upset condition.
This provides added assurance and confidence of shipping no free standing water.
Should it be decided that 0.31% of free standing water is an excessive amount for shipping purposes, absorbant material could be added to a liner to reduce this to the point of elimination.
i784086
VI.
EPICOR I Liner Experience A.
Additional Dewatering EPICOR I liners produced during the early stages of Water Processing were not dewatered per the pro-cedure found in Enclosure 2.
Five liners were selected and dewatered for a second time per this updated (Rev.2) procedure. shows that no more than 0.75 gallons of water were removed by a more sophisticated procedure after the liners had been in storage for approximately five (5) months.
This shows that the free standing water is, in fact, relatively easily removed even by earlier, less string-ent dewatering procedures.
This test also showed that all liners should be dewatered per the Rev.2 procedure prior to shipping.
B.
Decanted Water During the additional dewatering procedure employment, effluent from the liners were sampled to determine what the radionuclide and chemical characteristics of the free standing water in the liners were.
In actuality, this decanted water is dependent upon the equilibrium of various water characteristics and the resin itself.
It therefore could vary dependent upon the exhaustive stage of the bed.
However, for infor-mation purposes, Enclosure 5 is provided for reference purposes.
Of particular interest is the relatively low concentrations of the radionucli.'es.
Most are less than 10 CFR-20 MPC concentrations.
This informa-tion provides a measure by which it is understood what 1784 087
impact release of free standing water from the liner might have.
VII.
Cogclusions The resin liner lewatering testing program shows that the various tec..niques can successfully dewater resins.
Weepage and handling vibration would produce less than 0.3% free water in the liner following dewatering.
This water when sampled on an EPICOR I demineralizer had very low levels of acti' city.
Under existing shipping and burial guidelines, the Dewatering Procedure employed satisfies requirements.
Should additional margin of safety be de-sired, additional moisture drying techniques can be em-played.
