, FOREIGN CONTAMINATES IN UF6 CYLINDERS AND PROCESS' SYSTEMS o

The presence of. foreign contaminates in UF cylinders.and process 6

. systems is~ prevented through controls' associated with UF

receipt, 6

processing, cold trapping, maintenance, storage and transportation.

The -first. category, UF receipt, describes these controls associated 6

with receipt of UF in Model 30 shipping packagir.gs.

This categnry also 6

-covers cylinder procurement.

The second category, UF6 processing, describes controls associated with processing cylinders. (vaporization by both IDR or ADU systems).

This category covers preoperational cylinder and process checks, processing and post operational cylinder checks.

The third category, UF old trapping, describes controls associated 6

with cold trapping operations Dom Model 30 to Model 8 UF cylinders.

6

.This category specifically addresses the controls that are maintained to prevent oil additions to UF cylinders.

6 The fourth category, UF6 process and cylinder maintenance, describes the aspects of maintenance involving UF6 cylinder (valve replacement and decertification) and process systems (oil filled pressure gauges).

The fiftn category, storage and transportation, describes the controls associated with on-site storage of cylinders and, in addition, transport of cylinders off-site to be refilled, washed or decertified.

1.14.1 UF6 RECEIPT UF is received in Model 30 cylinders in NRC/ DOT authorized packagings.

6 These cylinders are inspected for damage upon receipt so as to ensure cylinder integrity. Cylinders (non-Westinghouse) are further inspected to determine that they are constructed and decertified in accordance with ANSI N14.1, " Packaging of Uranium Hexafluoriae for Transport."

w Valve covers are removed for weight verification; at this time, the tamper safe seal is inspected.

If the seal has been compromised, the cylinder will not be accepted for processing, Cylinders that are acceptable (meet defined requirements) are dispositioned for storage to await processing.

New cylinders (Westinghouse-owred) are designed, fabricated,

tested, inspected and cleaned in accordance with ANSI N14.1 to assure that foreign contaminates are eliminated prior to initial use of each cylinder.

Thereafter, cylinders are washed and recertifieo within the frequency as defined in ANSI N14.1.

1.14Property "ANSI code" (as page type) with input value "ANSI N14.1.</br></br>1.14" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process..2 UF6 PROCESSING l

Cylinders are transferred from storage to the UF bay where they are 6

staged for process checks.

Cylinders are cold vacuum checked to ensure cylinder integrity through the transportation and storage period.

Cylinders that do not have acceptable vacuum are tagged for engineering disposition.

l Cylinders are then placed in vaporization chests for processing.

Pigtails are inspected for cleanliness and connected to the cylinder valve and process line to permit the flow of UF from the cylinder to the 6

conversion procers system.

Connections are made while the cylinoer valves are closed.

Cylinder line UF pressure is monitored via a olaphram 6

pressure gauge.

These pressure gauges are limited to halocarbon oils that are compatible with UF *6 011 additions to line pressure gauges are identified in area operations procedures.

These procedures specifically describe that halocarbon oils are to be used.

In addition, halocarbon oils and grease are used elsewhere on process lines that niay contain UF.

Actuator valves with 6

interlocks on process lii ensure that foreign contaminates will not backflow to the UF6 cylinders.

' After. cylinder processing, an on-line eduction system is used. to further reduce.the uranium : content of the cylinder.

This eduction process uses g

only nitrogen.

After educt. ion, - the cylinder valve is closed. and the pigtail. removed..

After cooling, a vacuum check is performed.

If the cylinder is not under acceptable weight or vacuum, the cylinder is dispositioned for cold trapping.

Acceptacle weight and vacuum cylinders

'then 'have tamper safe seals applied to valves and are dispositioned for storage.

1.14.3' UF6 COLD TRAPPING The UF cold trapping systems (IDR and ADU) are designed for further 6

eduction of UF (to " heel" quantitles) from Model 30 UF cylinders.

6 6

The systems consist of the following:

(1) refrigeration compressor, (2)

Model 8 or 12 cold trap cylinder, (3) refrigeration chamber for Model 8 or 12 cylinder, (4) alumina packed columns, (5) oil trap and (6) vacuum pump.

In addition, the IDR cold trapping system is equipped with a heat exchanger for heating model 12 cylinders on-line.

UF6. gas flows from Model 30 cylinder to Model 8 or 12 cylinders by vacuum transfer where it is cooled and condensed to solid UF.

at 6

(steam or hot water) is often applied to the Model 30 cylinder to enhance this transfer process.

Uncondensed UF is collected in one of two 6

alumina packed columns connected in series between the Model 8 and 12 cylinders and the oil trap.

This process continues until the Model 8 and 12 cylinders are filled to an approved limit.

Once filled, the Mcdel 8 and 12 cylinders are processed on a conversion line.

To prevent foreign contaminates (oils) from entering the Model 8,12 and 30 cylinders, oil traps are installed between the cylinders and the vacuum pumps.

This oil trap has a volume capacity of approximately 1.5 times the oil volume capacity of the vacuum pump.

Oil traps are provided with drain valves to allow inspection and removal of materials prior to oil addition to the vacuum pump.

To further safeguard colo trap operations, only oils and greases compatible with UF (halocarbon) are useo in the vacuum 6

system.

Cold -trapping Model 8 and 12 cylinders are also designed, fabricated,-

inspected and tested in accordance with ANSI N14.1, Standard for packaging

'of UF for transport.

6 1.14.4-UF6. PROCESS AND CYLINDER MAINTENANCE Foreign. contaminates are eliminated from UF process systems and 6

cylinders through an effective maintenance program.

Maintenance on UF6 process systems encompasses process lines, valves and gauges.

Process lines and valves are maintained to ensure their integrity from leakage and possible entry paths for foreign contaminates.

Maintenance of pressure gauges involves routine calibrations and additions of oils compatible with UF (i.e.,

when oil type gauges are used on 6

UF6 process lines).

Foreign ' contaminates in UF cylinders are minimized or eliminated 6

through detailed procedures describing UF6 cylinder valve replacement, in addition to washing and decertifying of cylinders in accordance with ANSI N14.1 guidelines.

When cylinder valves are shown to be defective, the cylinder is dispositioned for valve replacement.

The procedure for valve replacement involves:. 1)' ice down of cylinder, 2) clean cylinder top after ice down,

3) position ventilation tent over vaporizer, 4) nbtain, inspect and clean, if necessary, replacement valve, 5) remove valve under ventilation tent,
6) immediately install replacement valve, 7) establish cylinder vacuum prior to processing.

This procedure ensures that foreign contaminates will not enter UF6 cylinders during valve replacement.

Breached cylinders remain under continuous operations and/or maintenance surveillance until secured (i.e.,

valve replaced).

The new valve is then equipped with a tamper safe seal, if disposition for storage.

4 UF cylinders are also routinely washed, inspected and decertified in 6

p accordance with ANSI N14.1 guidelines.

This will ensure removal of any L

foreign contamination that may have entered the cylinders.

'1.14.5 UF6 STORAGE AND TRANSPORT UF cylinders are stored in approved areas while awaiting processing or 6

j transport.

Tamper. safe seals are placed on all cylinder valves and plugs to detect tampering and possible entry of foreign contaminates, of cylinders that are dispositioned for storage outside the facility.

However, cylinders in the UF Bay are excluded from tamper sealing, as 6

well as: cylinders dispositioned for decommissioning or washing.

Cylinders in the UF Bay are considered in prot, ass until released for storage.

6 Cylinders dispositioned for transport (full, beel and decertified cylinders) are inspected for damage and the integrity of appropriate tamper safe seals established prior to release.

Cylinders in good condition (i.e., valves and plugs) will not permit entry paths for foreign contaminates.

Transportation of cylinders off-site (full, heel and decertified only) generally require sole use of the transport vehicle.
