SNM-ll74 TERMINATION PLAN - PART III (Revised November 29,1978) 1.0 Solvent Extraction Glovebox and Equipment 1.1 Introduction j
The solvent extraction (S.X.) area floor plans are shown on pages 9-5 and 9-8 of our application of August 7, 1976.
The S.X. glovebox is' designated as number 2.A.
This U shaped box, if rectangular, would measure about 36' x 36' x 2.5' deep.
The basement portion of the S.X.
system is in room B-05 while the above g und level portion is indi-cated to be part of room 127.
The U shan box surrounds a personnel working area. This working area has two tal floored levels above the basement level.
Each level has a door. When these doors are closed, the S.X. area is isolated from the rest of the building.
Drawing No. CPP-600M-114-0 (attached) shows the floor plan view of the S.X. glovebox 27A, its air supply and its air exhaust glovebox No. 27B.
The S.X. system was sized for scrap recovery feed rates much larger than the amounts generated during the operations of the plutonium plant.
The system was seldom used and is considered obso-lete even if the plutonium plant were to return to. operating status.
The S.X. area was cleaned in preparation for the standby status of the plant.
The cleaning methods inside Box 27A included complete draining of all vessels and piping, sludge removal, circulating fresh TBP and dodecane through the equipment (twice), followed by a trichlo-roethane rinse.
The box walls were pressure spray cleaned with trichloroethane.
Analysis of the collected cleaning solutions showed that the concentration of plutonium in them never exceeded 10 grams per liter.
These solutions were properly disposed of.
Monitoring, contamination controls, administrative controls, precautions and procedures will apply as described in our letter of November 8, 1977
" General Aspects of the Termination Plan", and our letter of October 11, 1977 " Termination Plan Part I".
In addition, the following actions will be taken to accomplish the removal and disposal of the S.X. process.
1.2 Description of S.X. Equipment Within glovebox 27A are four inch (I.D.) tanks and pulse columns most of which are made of stainless steel.
Some have flange fitted glass sections.
The stainless steel. piping ranges in thickness from schedule 80 to thin
. all tubing.

tanks, and six pulse columns all of which are approximately 32 feet tall.
There are two agitator equipped organic - acid wash tanks each 10 feet tall, two overflow and catch tanks each 10 feet tall, two feed break tanks six feet tall,16 miscellaneous tanks three feet tall and 18 smaller tanks (Pots) ranging from six inches to one foot tall.
Of the glass columns, there are four which are eight feet tall, six are four feet tall and six which are two feet tall.
There is approximately 1,550 feet of piping.
b
1 There are six pulse generating remote-head diaphragm pumps outside of l
the glovebox each with a slave unit housed within the box, coupled through a hydraulic line. Similarly, there are 29 feed and circulating pumps.
Other equipment within the box includes valving, liquid level control sensors, fire suppression equipment (Halon system) and ventilation ducts.
The box itself is made of stainless steel with plexiglass windows and glove ports. Ventilation within the box will be maintained until the box no longer exists. The halon fire extinguishment system within the box will be preserved until all other equipment has been removed and until i
the inner box surfaces have been cleaned. The halon system protecting the personnel working area will be preserved until the box disassembly is completed.
Room working area ventilation shall be maintained throughout the S.X. box dismantling activity.
Lighting by fluorescent lamps and high intensity lights will provide good j
visibility through the ample number of glove box windows.
If needed, flashlights can be bagged into the box.
.l.3. Special Equipment J..
Prior to further glovebox cleanout or'disassemblyj ~special equipient as described below shall be constructed, tested and evaluated.
Personnel training to assure proper and safe operation shall be accomplished before the equipment is committed to the disassembly activities.
1,3.1 N.D.A. Glovebox and Shipping Container " Bag-Out" Box
^~
Provisions are to be provided which will permit pieces of equipment to be transferred from the S.X. glovebox into a new gl.ovebox or tunnel which has N.D.A. instruments. After the equipment pieces have been measured, they will move directly into a new drum loading glovebox, exiting the box through the drum liner sleeve which is attached to the box bag-out port.
The pieces are thusly placed into the drum.
The drum has two plastic liners. The first is a bag liner placed into the drum forming the sleeve described above, while an inner liner (with lid) is a heavy self supporting plastic insert. This insert protects the i
1.ighter bag from puncture.
After the drum is loaded, the lid is placed on the heavy plastic insert and the drum is rotated, twisting the sleeve above the drum contents.
The twist is taped and cut. The outer drum lid, with a gasket, is then secured in place.
The drum is then transferred to the vault or to room 121, awaiting shipment to a licensed disposal site.
The drum is tampersafed (using the two men rule) and identified as

e qv An especially designed rotating fixture will be provided to permit a plasma arc cutting torch to slowly encircle a four inch (I.D.) pipe.
When cutting, the torch and the fixture are in a non-combustible enclosure or shroud into which a nitrogen rich atmosphere is provided.
A long length i
of pip.e, suspended in:a vertical posit on, is lowered into the fi.xture and a section cut'off which can be safely handled, N.D.A. counted and 1
N.
t packaged. The pipe is again lowered and cut repeatedly until the pipe is completely sectioned.
l 2.0 Further Cleaning of the S.X. Area Before dismantling the S.X. equipment, gloves and bags will be placed on Box 27A which will permit the placement of a single five inch diameter, i
two or four liter poly bottle in the bottom of the box into which hydra-ulic pump oil will be placed. Only one bottle will be permitted in the i
box at a time. The bottles will contain absorbant in a quantity sufficient to absorb twice the amount of oil in the bottle. The filled bottle will be bagged out of the S.X. box before another empty bottle is bagged into the S.X. box.
Filled bottles will be stored in a safe array not to exceed 10 bottles separated one from the other with a minimum of 2 feet of air space.
The bottles will be individually counted using N.D.A. equipment.
l The bottles will be cemented into 55 gallon drums in guch a manner as not i
to exceed an average concentration of 5 grams per ft.
in the drum.
The S.X'. pumps and piping external to the S.X. glovebox will. be removed.
Instrumentation, control cabinets and unneeded electrical circuitry external to_the: box will also be removed from box 27A.
A small electric

' solutions to' box 27A. The 'used decontamination solutions' will' be pumped from the bottom of the box and transferred to two or four liter five inch diameter poly bottles which are then cemented into drums in the manner l
used for pump oil.
j
' Additional gloves will be placed on box 27A as needed to facilitate the 4
final cleaning of equipment and ' surfaces inside of the box.
Cleaning will j
start at the top of the box and progress downward. Spray nozzles will be used as well as manual cleaning methods.
Previous cleaning.of this box by these methods never produced solutions with plutonium concentrations exceeding 10 g/1.
Plutonium solutions at 10 g/l has a safe slab thickness exceeding 12 inches. The liquid accumulating in th5 bottom of the box will i
be maintained less than two inches deep. A liquid level probe / alarm is installed at a height of one inch above the bottom of the box. This alarm i
i will be maintained until box 27A is empty of equipment and has had its a
final wash.

un fasteners or cutting into pieces fitting the shipping drum. This will make room for working on the larger and heavier five inch (0.0.) columns and tanks. Eye bolts or other devices will be fastened into the top of the box above the five inch diameter vertical pipes. A chain fall or similar device will be attached snugly to tie bolt and the pipe.
The pipe supports will then be cut from the pipe. The pipe will then be lowered by 10 to 18 inch increments into the plasma arc cutter.
Only one column at a time will be sectioned in this manner.
Glass column sections will need to be removed whole. Those sections too long for drums will be removed using conventional bag out methods or by window removal using " greenhouse" techniques. They will then be N.D.A.
evaluated and packed in Specification 7A boxes.
At the end of each working shift, or more frequently, cuttings which have accumulated in the bottom of the box.will be collected in a single quart ice cream container, N.D.A. counted and drummed to assure that a safe slab of two inches is not exceeded. This will be repeated until the gross accumulation of the cuttings are properly disposed of. The quart containers are cylinders with diameters < five inches. -

9.0 Additional Security Measures In addition to the security measures authorized in our " Standby" license dated July 15, 1977, the following will.be accomplished:
a)
The ' sample." pass through window" locsted on the east exterior wall of laboratory room #140 will be completely covered with steel from the outside to prevent anyone from reaching through this window. The use of the SNM detector and alarm for this location may be discontinued.
This will be done before_ equipment removal from box 27A.
b)
When the NECO truck arrives, the guard checks the driver's credentials,
~
requires him to sign "in" on the log, and performs his routine " frisk",
etc. After acceptable reception, the guard permits the truck to pass through the fence gate and park at the dock.
The driver then promptly exits the fence gate and returns to the guard, all while in view of the guard or an escort. The driver waits in the lunchroom or office area until his truck is loaded and sealed. After passing the guards i
exit check, the escorted driver returns to his truck through the j

j The NECO truck is' loaded by Cimarron Facility employees.
During truck l
loading, packages moving at any one time from room 121 to the truck will be limited to the space available in the airlock (room 120).
)
First, the overhead door ("A" door) separating room 120 from 121 will be opened, packages moved into room 120 and then "A" door will be closed._ A H.P. technician will then survey all. persons moving the packages with a G.M. instrument and a metal detector before moving the packages from room 120.
Next, the overhead door ("B" door) between room 120 and the outside dock will be opened to allow the material to move to the truck.
The "B" door is then closed before the "A" door is again opened.
Person-nel re-enter room 120 using trie man door in the "B" door. During the truck loading, persons are not permitted to exit the fence gate.
1 The fence gate is controlled by the armed guard. The above procedure is repeated until the truck is loaded. Personnel return through the plant and guard station before leaving the Facility.
c)
No empty or partly filled drums (or other shipping containers) will be placed in room 121.

The individual requirements for data collection, measurements and sampling requirements are outlined in appropriate safeguard procedures. The e
collection and processing of this data is the responsibility of the' Health & Safety Supervisor. Typical N.D. A. measurement procedures are illustrated in Appendix K of our application for the Standby license, a
dated August 7,1976.
This is supplemented with the use of procedure KM-NC-15-56 titled " Limit of Error Manual". ' Low-level liquid wastes are measured by N.D.A. or radioassay techniques as required by procedure 2
KM-NP-15-46. Thh procedure also covers' check weighing.
The interpretation, analysis and reporting of the measurement results to i
management is the responsibility of the Health & Safety Supervisor.
i physical inventories of the plutonium will be under the direction of the Health & Safety Supervisor. This individual is also responsible for the investigation and reporting to the Manager all shipper and receiver differences.
i j
The accumulation and reporting of the inventory data in compliance with 10 CFR 70.51 (3)(5) will be completed by the Health & Safety Supervisor.
The final reporting of the results to the Nuclear Regulatory Commission is'the Tesponsibility.of.the Plant Manager. 'The inventory report _is sub-S

10.4 Management of Materials Control System 4
At least once each year, an internal review of the overall system of i
Special Nuclear Material Control will be conducted for corporate Management, and reported to the Plant Manager. The audit will cover accuracy, com-l pletness and adherence to accountability and safeguards procedures and existing regulatory requirements.
i An apparent loss of a discrete item or container of Special Nuclear Material which cannot be resolved by an immediate investigation shall be reported to the plant Manager, who shall promptly notify the Nuclear Regulatory Commission, Director of Inspection and Enforcement, Region III, Glen Ellyn, j
Illinois and shall conduct an investigation of the loss. The Plant Manager shall report the results of his investigation to the General Manager, Nuclear Manufacturing.

SNM Material Transfer Carts, Nuclear Safety ' Analysis Pu-G-2 Battelle Pacific Northwest Laboratories provided an extensive criticality analysis for the general use of the transfer cart in the plutonium plant.
The degree of ;ubcriticality for the material and conditions assumed showed a K-eff F 0.747 for Pu02 powder unreflected and 0.945 with full water reflection.
12 SNM carts in a 4 x.3 array is considered to be the most reactive arrangement for. SNM carts possible anywhere in the plant.
The 42 Pu02 powder can is the most reactive of the fissile materials and was used in the solid angle neutron interaction calculation.
Due to the designed spacing of cart storage rings, the fissile material from SX clean out, and the previously described analysis--BNWL-Pu-G-2, there;should not be limited movement of carts containing SNM material in proximity of other SNM material.

1.
Cart must be loaded with only one type of material.
2..
The 2 or 4 liter bottles must be located in the two central location rings.
3.
Cart loaded with plastic bags containing scrap: Use the single parameter limits given.in TID-7016. A 200g total plutonium load verified with NDA measurements meets the criteria.
Place about 1/2 of the load on the bottom shelf.
4.
Space carts 2 ft (minimum) from other fissile material.
3.
SNM material may be stored in single arrays.
Because of maintenenace scheduling and/or instrument failure, any array formed without NDA measurements must be "so marked, dated and recorded in the Facility Manager's Log." -Array spacing is 24" edge to edge.
Arrays formed without NDA measurements are limited to three items of like kind.
4.
Scrap material "such as piping" must be taped and packaged in 5" bundles or less.
Maintain 2-foot spacing from other fissile materials.
