DEMONSTRATION REPORT - MPW INDUSTRZAL SERVICES, INC. ]FOR WESTINGHOUSE HANFORD CORPORATION

i

I. BACKGROUND - Westinghouse Hanford Corporation has been pursuing strategies to break up and retrieve the radioactive waste material in single shell storage tanks at the Hanforcl Nuclear Reservation, by working with non-radioactive ''saltcake'' and sludge material that simulate the actual waste.

It has bleen suggested that the use of higher volumes of water than used in the past (10 gpm nozzles at 10,000 psi) might be successful in breaking down the hard waste simulants. Additionally, the application of these higher volumes of water might successfully be applied through commercially available tooling using methods similar to those used in the deslagging of large utility boilers.

MPW Industrial Services, Inc., has proposed a trial consisting of three approaches each to dislodging both the solid (saltcake) simulant and the sludge simulant.

11. TRIAL PLAN - Under ithis proposal, MPW would attempt to dislodge the solid simulant in three &foot square x 2-foot deep beds (see Fig. 1 in appendix for pan configurations) with these approaches:

A. Rotary tooling approaching straight down from above the center - four nozzles, 12.5 gpm each at nominal 10,000 psi - 45 degree angle of attack - four-sided box (see Fig. 2 in appendix.)

B. Rotary tooling in at a 45 degree angle from above and to the front, starting at several feet - two nozzles, 25 gpm each at nominal 10,000 psi - three-sided, open fiont (see Fig. 3 in appendix.)

C. Straight in to the exposed edge of the material with an articulated "water cannon" - flow rates of 25 and 50 gpm at nominal 10,000 psi - three-sided box, open fiont (see Fig. 4 in appendix.)

The trial, points above would be repeated with three pans of sludge simulant, each 4-f;oot square x 1-foot deep.

Pressures, flow rates, stand-off distances, and a description of the results would be recorded for each trial.

111. SAMPLE PREPARATION - A. S,altcake - Samples of the hard (saltcake) simulant were prepared using 7’20 - 50 lb. bags (18 tons) of potassidmagnesium sulfate “langebeinite”, (product trade name “Dynamate”, obtained fiom Ingredient Resource Cop., 1-800-729-7290), per WHC recommendations. Two 3-cubic foot cement mixers were used, mixing at a ratio of 7 bags Dynamate (350 lbs) to 8 gallons of water (66.7 lbs), for a total weight per mix of 416.7 Ibs, and a solids ratio of 84 percent.

Each chlarge was allowed to blend for 20 minutes, after which it was lump free and homogeneous. 240 bags were used to fill each 8-foot square pan. An electric compactor was inserted at intervals and held for 2-5 seconds, or until the: air bubbles ceased to rise. Each pan was covered with plastic and the top of the plastic filled with water, to prevent evaporation during curing.

It should be noted that the original figure of 90 Ibdcubic foot supplied by WHC was incorrect; the 240 bags (12,000 lbs.) filled the 8’ x 8’ x 2’ pans to an approximate depth of 20 inches (1.67 feet), for a dry material weightlcubic foot of 112.3 lbs, and a wet weight density of 133.7 Ibdcubic foot.

Sample mixing began Monday, September 25, and concluded Tuesday, Septem’ber 26; the trial took place October 10, for a minimum 14-day cure time.

B. Sludpe - Samples of the sludge shulaut were prepared using 80 - 50 lb. bags of Kaolin Clay (“EPK - pulverized Kaolin”) purchased fiom Feldspar Cop. (904-48 1-242 1).

The c1a.y was blended at a ratio of 66 percent clay, 34 percent water, by a professiional blending company, E.C. Moms, in Wadsworth, Ohio, and returned to MPW in 55-gallon open-top drums.

The resulting mixture was emptied, two drums each, into three pans each 4- foot square x 1-foot deep. It was necessary to use a shovel and hoe to smooth the material, which was the consistency of peanut butter.

IV. TRIAL SET-UP -

1

1

A 20-ciubic yard roll-off box with 12-feet of the center cut out of one side, and the remaining sides extended up 8-feet, was the choice for a backdrop against which to blast the material. A track was installed horizontally approximately 12-feet above the bottom of the box, in the center of the opening perpendicular to the length of the roll-off box. Rollers were installed on the hangers, permitting the waterblast hose attached to the tooling to move both in and out as well as up and down. See Fig’s 5a and 5b in appendix for photos of trial set-up.

Winches were installed to position the tool horizontally, as well as vertically.

StoneAge MJV rotary heads were used, each capable of up to 100 gpm at 10,000 psi, although the trial plan called for flows to only 50 gpm. The original trial plan was to hang these heads fiom the waterblast hose with a supplementary weight; the stability, with balanced nozzles, would have been adequate for normal cleaning operations, such as that done in large boilers. A typical head set-up is shown in Fig. 6 in the appendix.

All nozzles in the trials are Rankin Shapejets with triangular openings except the 50-gpm water cannon nozzle, which is a standard round (Leach and Walker) carbide nozzle.

A 350 HP waterblast truck unit was staged at the trial site, and fed by a diesel-powered pump fiom a water supply tank. (This is due to the lack of availabdity of a 50 gpm water supply close to the trial site.) A hand-held tachometer was used to directly read pump rpm, which equates to flow rate. Fig’s. 7a and 7b in the appendix show the buck and water supply configuration.

A high-volume foot pedal was used as the primary pressure relief device.

As the pressure drop in the 1/2” waterblast hose was calculated to be approximately 1400 psi at 50 gpm, at this point in the trial it was decided to change to 1-inch hose; this would present a neghgible pressure drop, thereby increasing nozzle pressure.

Tool lifts when pressure is applied due to contraction of hose; tool was lowered after start-up to where nozzle streams hit corner of material - no erosion

Trial No. 2(b) - -- Up to this point, as mentioned previously in this report, the tool had been allowed to swing fiee from the hose, as is done in some cleaning operations; however, it was felt the lack of repeatedly cutting into the same path contributed to our inability to break up the hard simulant.

Therefixe, it was decided to iix the tool to a stationary crossmember - this more nigid attachment could be reasonably duplicated in the actual cleaning of a tank. The rest of this trial is executed with this configuration. See photos, Fig. 10 and Fig. 1 1.

At this point, it was impractical to lower the nozzle further, as the nozzle configuration would not permit lowering. The decision was made to change back to the 4-node configuration to see if the more stationary tooling set-up would ]permit continuation of the cutting to a greater depth. See photo, Fig. 16.

VI. CONCLUSIONS - The dltcake simulant turned out have more tensile strength than expected; where it was thought that hitting it with a high volume of high pressure water would open up natural cracks in the material, this did not happen. Where concrete breaks down in hydrodemolition by eroding the interface between cement and aggregate, there are not interfaces of this nature in this simulant; the product is very cohesive, and the bonds appear to be more difficult to break.

While i3 machining action such as effected by the University of Missouri - Rolla brids appears to be more appropriate for this material, as would the stronger cutting actions of ultrahigh pressure jetting (30,000 psi and higher), the effective standoff distances decrease. sigmtlcantly over the goals of this demonstration.

I

i

Possiblc: reasons for the difliculties in breaking down the material, other than it possibly being an exceptionally strong sample compared to previous simulant samples, are as follows:

1.

2.

The angle of attack of the rotary tooling - a nominal 45 degrees - was too great, resulting in a glancing action against the hard material.

The use of larger volumes perhaps results in a less precise force on the material; an analogy would be the use of a butter knife as opposed to a surgeons scalpel to open up the bond within the material. This parallels our experience in hydrodemolition at 20,000 psi, where a nozzle at 21 gpm has been demonstrated to be superior in some cases to one at 43 gpm in breaking the cement-aggregate bond.

Suggestions for follow-up trials with the already-existing simulant beds are as follows:

1 . Increase volumes to 100 gpm at 10,000 psi. This would mean a nninimum of 25 gpm in a four-nozzle configuration, and up to 100 gpm i n a water cannon arrangement. (Note that the water cannon at 100 gpm would represent 200 gpm in an actual tank retrieval, considering the opposing nozzle, unless an arm capable of a 500-600 pound reactive force is used.)

2. IJse a rotary tool with radial nozzles 90 degrees to the axis of the tool, resulting in an angle of attack moving through 90 degrees to the material.

3. IJse a polymer additive, resulting in a more focused nozzle pattern, and therefore increased forcdunit area to separate the material. The proposed polymer is biodegradable and non-hazardous.

4. lJse hot water - to 180 degrees - to blast the material at the pressures and volumes used in this demonstration.

5 . lJse 20,000 psi, which is usually the pressure used for hydrodemolition of concrete.

The above approaches all constitute approaches now in commercial use by h4PW Ihdustrial Services, Inc.

It also should be noted that it is unlikely that the simulant is a true representation of the material in the tanks at Richland; it is suspected that the actual material lacks the monolithic, homogenous nature of the simulant as

11

i

1 .

seen in this demonstration. A true simulation of the in-gomd mated would most probably offer stress cracks and other interfaces and areas of lower strength which would permit a process of blasting the material apart a greater opportulnity of success.

HAZARD BY ROUTES OF EXPOSURE:

INHALATION: WARNING: These products contain crystalline silica. Repeated, prolonged inhalation of dust may cause delayed lung injury which may result in silicosis or pneumoconiosis. The International Agency For Research On Cancer in its publication, "IARCMonograph On The Evaluanon Of The Carcinogenic fisk To Humans - Silica and Some Sdicates" - Volume 42, 1987, has concluded that there is sufficient evidence for the carcinogenicity of crystalline silica in experimental animals, and limited evidence for the carcinogenicity of crystalline silica in humans, and has, therefore, classified crystalline silica in Group 2A of Probable Carcinogens. The National Toxicology Program's ("NTP's") Six* Annual Report on Carcinogens lists crystalline silica (respirable) as a substance which may reasonably be anticipated to be a carcinogen. In support of this listing, NTP cited the IARC conclusions mentioned above. The animal studies found mcreased tumors m rats resulting from inhalation, intratracheal instillation, and interpleural or intraperitoneal injection. In humans, a number of studies have found an association between lung cancer and exposure to dust containing respirable crystallme silica. These studies only rarely, however, included data on smoking, potential confounding exposures, and assurance of the comparability of the referent population. -- INGESTION Nausea nmy result from accidental mgestion May cause cancer, based on m a l data
