SUBJECT:

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET NOS. 50-445 AND 50446 REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS PURSUANT TO 10CFR20.1705 WITH USE OF FRENCH DESIGNED AIR SUPPLIED RESPIRATOR EQUIPMENT Gentlemen:

Pursuant to the provision of I OCFR20.1705, "Application for use of higher assigned protection factors," TXU Generating Company LP (TXU Power) hereby requests authorization to use French designed air supplied respiratory equipment (Delta Protection's Mururoa suit) with an assigned protection factor (APF). A detailed request for authorization is included as an Attachment to this letter.

Specifically, pursuant to IOCFR20.1705, TXU Power must obtain authorization from the Nuclear Regulatory Commission before using assigned protection factors in excess of those specified in Appendix A of IOCFR20. Appendix A to IOCFR20 specifies that an air-supplied suit may be used in continuous flow mode at a licensee's facility, but without using an assigned protection factor. Since these suits have no assigned protection factor, TXU Power is requesting authorization for their use as respiratory protection equipment with an assigned protection factor of 5000 based on a fit factor of 50,000 per the manufacturer's testing results (Enclosures 3 and 6 of this letter). National Institute for Occupational Safety and Health (NIOSH) approval for these air-supplied suits is not required per the provisions of IOCFR20, Appendix A, Footnote g. Based upon easy egress from the suits, and their prohibited use in immediately dangerous to life or health (IDLH) environments, CPSES does not plan to provide standby rescue persons when this equipment is used.

V TXX-05163 Page 2 of 4 By letters dated January 25, 2005 and March 14, 2005, Florida Power and Light Company (FPL) requested authorization (1) to use French designed respiratory protection equipment that has not been tested and certified by NIOSH, and (2) to take credit for an assigned protection factor (APF) of 5000 for this equipment. By letter dated April 8, 2005, the NRC staff concluded that authorization of these requests was acceptable, and within the provisions of Title 10 of the Code of Federal Regulations, Part 20. ADAMS Accession Numbers for the above letters are ML050310410, ML050760313, and ML050980119 respectively. This authorization request by TXU Power includes supporting documentation that is similar to that provided by FPL in their request.

TXU Power intends to integrate the use of the Mururoa suits into our existing respiratory protection program that satisfies 10 CFR Part 20 requirements. The following summary of controls and program elements contains the following new commitments which will be completed prior to use of the Mururoa suits at CPSES.

Since TXU Power has a viable and ongoing respiratory protection program, only those items specific to the use of the Mururoa suits are discussed below.

Commitment Number Commitment 27365 The Mururoa V4 Fl and V4 MTH2 suits will be integrated into TXU Power's respiratory program using the information provided by the manufacturer. New lesson plans will be developed to train workers on Mururoa's features, donning, use and removal, cautions, and use of mouth strip and tear off strips for routine and emergency egress. Radiation Protection personnel will be provided additional training on selection, approval, issue, equipment set-up, operation and maintenance instructions for the Mururoa suit.

27366 TXU Power will use the site's Corrective Action Program to document any unexpected problems and track corrective actions taken. Problems associated with the suits will be communicated to the manufacturer to ensure that operating experience is shared with other users. A relationship with the manufacturer (or its representative) will also be developed that allows operating experience from other users to be incorporated into TXU Power processes.

TXU Power will share this experience with the NRC and other utilities that may be interested in the Mururoa suit.

TXX-05163 Page 3 of 4 27367 Section 20.1703(c)(4)(vii) requires, among other things, written procedures governing respirator storage and quality assurance. TXU Power shall implement the provisions in the manufacturer's "Instructions For Use," with the minor clarification that the suits will be inspected and removed from their protective packaging outside of the plant's radiological controlled areas, in a way that maintains the integrity of the suit, but does not lead to the unnecessary generation of solid radioactive waste.

27368 The Mururoa suits are single use only, and are not approved for use in atmospheres that are immediately dangerous to life and health (IDLH). TXU Power will discard each suit (other than those segregated for training purposes only) after one use.

TXU Power would like to begin using the Mururoa V4 F4 and V4 MTH2 suits during the October 2005 CPSES Unit 1 refueling outage. Therefore, TXU Power is requesting the subject authorization by October 1, 2005.

1.0 INTRODUCTION

1.1 PURPOSE TXU Generating Company LP (TXU Power) requests NRC authorization to (1) use and take credit for the protection provided by two French-designed air-supplied respiratory protection suits during normal (non-emergency) operation, and (2) take credit for an assigned protection factor (APF) of 5000 at the Comanche Peak Steam Electric Station (CPSES). The suits are manufactured by Delta Protection, 30200 Bagnols su C'eze, France, and are identified as Mururoa V4 Fl and Mururoa V4 MTH2. Both models are single-use suits (a suit that is disposed of after one use). TXU Power proposes to use the suits in the approved configurations relative to the suits' form, fit, and function.

This attachment provides evidence that the material and performance characteristics of the Mururoa suits are capable of providing the proposed degree of protection under anticipated conditions of use as demonstrated on the basis of reliable test information.

1.2 REGULATORY REQUIREMENTS 1.2.1 Requirements of 10 CRF 20.1705, and Appendix A to Part 20 The following regulatory requirements are relevant to this request.

10 CFR 20.1705 Application for Use of Higher Assigned Protection Factors, requires that the licensee shall obtain authorization from the Commission before using assigned protection factors in excess of those specified in Appendix A to Part 20. The Commission may authorize a licensee to use higher assigned protection factors on receipt of an application that:

a) Describes the situation for which a need exists for higher protection factors; and (b) Demonstrates that the respiratory protection equipment provides these higher protection factors under the proposed conditions of use.

Appendix A to Part 20, Assigned Protection Factors, lists as item 11, Atmosphere supplying respirators (particulate, gases and vapors), "Suit" in a continuous flow operating mode, with reference to Note g. Note g states: "No NIOSH approval schedule is currently available for atmosphere supplying suits. This equipment may be used in an acceptable respiratory protection program as long as all the other minimum program requirements, with the exception of fit testing, are met (i.e., 10 CFR 20.1703)."

Therefore, based on the above requirements, TXU Power requests authorization to use the Mururoa respiratory protection suits and to take credit for an assigned protection factor of 5000 for this equipment.

Attachment toTXX-05163 Page 3 of 8 2.0 TECHNICAL JUSTIFICATION 2.1 SCOPE 2.1.1 Situations for Which a Need Exists for Higher Protection Factors TXU Power currently uses bubble hoods forjobs involving high potential for skin contamination from discrete radioactive particles and to prevent intake of airborne contaminants. Because the bubble hood covers only the face and torso, workers have to wear additional protective clothing, two pairs of gloves, rubber shoes and cotton booties and tape for sealing. Chances of cross contamination during undressing/exit from contaminated areas are high. The Mururoa suits offer a better alternative (with their unitized construction and ease of removal) and will protect the worker much better against facial/skin contamination and airborne radioactivity. Approval of a protection factor of 5000 for the Mururoa suits would allow use of the Mururoa suits in TXU Power's efforts to control contamination incidents and prevent intakes during operational activities at CPSES Units I and 2.

2.1.2 Demonstration that the Respiratory Protection Equipment Provides these Higher Protection Factors under the Proposed Conditions of Use.

TXU Power reviewed the following documents from Delta Protection, France:

• Technical information on Mururoa V4 model ventilated suits (Enclosure 1)

• European Standard EN 1073-1 for ventilated protective clothing (Enclosure 2)

• Protection Factor determined during fit test exercises for V4 F I (Enclosure 3)

• Certificate No. 0073/197/162/12/97/0028 for Mururoa V4 Fl issued by the Institute for Nuclear Protection and Security (Enclosure 4)

• Protection Factor determined during fit test exercises for V4 MTH2 (Enclosure 6)

• Certificate No. 0073/197/162/01/96/0001 issued for Mururoa V4 MTH2 by the Institute for Nuclear Protection and Security (Enclosure 7)

• Donning and Removal Instructions for Mururoa V4 MTH2 and V4 Fl (Enclosure 8)

As discussed in the Florida Power and Light Company (FPL) letter of March 14, 2005 (ML050760313), the manufacturer has indicated that the "Instructions for Donning and Removal of The Mururoa V4 Fully Enclosed Suit" (Enclosure 5 to this submittal) are now outdated and are no longer supplied. The manufacturer's representative further indicated that the "M.T.H.2 Instructions for Use" (Attachment 8 to this submittal) are adequate for both the Mururoa V4 MTH2 and V4 Fl suits.

Attachment toTXX-05163 Page 4 of 8 The European Standard (Enclosure 2) requires single-use suit materials to be tested for resistance to abrasion, puncture, tear and flammability, strength of seams, joins and assemblies, damage resistance of exhaust valves, designed flow rates for pressure range of supplied air, noise level and quality of the visor. The protection factor (average inward leakage or fit factor) is measured according to draft prEN 941 -1 (Annex A).

According to the testing standard, test subjects perform standard exercises inside a chamber filled with a test agent (Sodium Chloride). Inward leakage is then calculated during an exercise regimen lasting approximately 20 minutes. Operating parameters are set to manufacturer's instructions. Standard exercises include walking on a treadmill at 2 mph (3 minutes), moving arms up and down above the head while looking upward (3 minutes) and squatting continuously (3 minutes). To ensure worker's comfort, two additional practical exercises, walking at 2 mph (5 minutes) and loading a bucket with wood chips from the base of a hopper and emptying it into the opening on top (15 minutes), should be performed by two workers at specified airflow rates.

Certificate No. 00731197/162/12/97/0028 (Enclosure 4) states that the Mururoa V4 F I passed in all categories tested and provided a protection factor greater than 50,000.

Certificate No. 0073/197/162/01/96/0001 (Enclosure 6) states that the Mururoa V4 MTH2 passed in all categories tested and provided a protection factor greater than 50,000. Please note that the term 'protection factor' used in the European Standard is equivalent to the 'fit factor' used in the United States and is not the same as the Assigned Protection Factor used in 10 CFR 20.

Based on TXU Power's review of the manufacturer's documentation, the Mururoa V4 Fl and V4 MTH2 suits represent a better design than the currently approved "bubble hood" and "rain suit" combination and provide better worker protection with data supporting an assigned protection factor of 5000.

The Mururoa suit's design does not permit its use in an immediately dangerous to life and health (IDLH) atmosphere. The Mururoa suit is also not designed for use with any personal cooling units such as a Vortex tube, but can be used with a cooling vest supplied by the manufacturer, if desired.

Attachment toTXX-05163 Page 5 of 8 2.2 DISCUSSION Evidence that the material and performance characteristics of the Mururoa V4 Fl and V4 MTH2 encapsulated single use suits are capable of providing the proposed degree of protection under anticipated conditions of use is provided in Enclosures 1 through 8. A summary of material and performance characteristics follows.

2.2.1 Suit Construction The Mururoa suit models V4 F1 and V4 MTH2 meet ISO 8194, European Standard EN 1073-1, and the manufacturer is ISO 9001 certified. The manufacturer indicates that approximately 60,000 Mururoa garments/suits are used by European Nuclear Power plants each year.

The Mururoa single use suits have the following desirable features that are not available in the "bubble hoods" and "rain suits" manufactured in the United States:

1) One piece single use suit that includes welded gloves and booties with tie straps

2) Fireproof (up to 65 deg C)

3) Made of PVC or Ethyfuge with reinforced elbows, knees and crotch areas.

4) Dual zippers - metal zipper inside and plastic zipper outside

5) Helmet made of clear PVC material that provides distortion-free vision and large enough for wearing a headset

6) Welded sleeve to insert communication cable

7) A removable strip near the mouth that could be used for emergency breathing in case of loss of supplied air

8) An egress strip stretching from the left arm, over the head, to the right arm that is used for undressing and for self-rescue in an emergency, such as loss of supplied air

9) An air intake located at the waist with a built-in regulator that can adjust, but not block, air flow

10) Two exhaust valves that provide ventilation and also protect from overpressure

11) Very low noise level at maximum air flow

12) Air flow to hands, feet, face and chest Air hoses of any length can be used, but air shall be supplied to the Mururoa suit (model V4 Fl) at 85 psig measured at the inlet. A regulator at the inlet can adjust the air flow from 43 CFM maximum to 19 CFM at the minimum. To ensure user safety, the regulator cannot shut off the air supply. Noise level is kept between 76 dB at maximum air flow to 58 dB at minimum air flow.

Air flows through manifolds to the chest, hands and feet. There are two exhaust vents on the back, one behind the neck and one at the lower back. The exhaust vents have patented magnetic seals to prevent any aspiration of contaminants if supplied air is lost.

The suit is made of non-flammable PVC, but should not be brought in direct contact with any material colder than 41 deg F or hotter than 140 deg F. Open flames or sparks could melt or perforate the suit.

Attachment toTXX-05163 Page 6 of 8 There is a shelf-life of 3 years for this suit and storage between 32 deg F and 140 deg F in original packing is required by manufacturer. The Mururoa is approved for use with 16 different fittings in Europe and can be fitted with the Hansen fittings used at CPSES.

The Mururoa suit model V4 MTH2 is made of Ethyfuge material which is fully incinerable. This material is more flexible than the PVC used in V4 Fl. It is constructed the same way as the V4 Fl. Breathing air is required at about the same pressure (85 psig).

The regulator can adjust air flow between 19 CFM and 43 CFM. Noise level varies from 58 dB at minimum air flow to 76 dB at maximum air flow. There are two additional air vents near the chin for cooling the face. The suit is also fire-retardant and can be used in ambient temperatures up to 140 deg F. Storage requirements are the same as the V4 Fl.

These suits are also available with multiple fittings.

2.2.2 Safety Features of V4 F1 and V4 MTH2 Models Both Mururoa suit models are light-weight (2.5 Ibs), made of fire-retardant material and can be used in temperatures up to 140 deg F. Contact with open flames or grinding/welding sparks is prohibited. Built-in gloves, booties with binding ties, reinforced elbows, knees and crotch protect against accidental tear, puncture and cracking. A transparent helmet with 6" X 8" clear face plate provides distortion-free view. Dual magnetic ventilation valves provide needed ventilation and relief of excess pressure in case the suit is squeezed and/or pinched unexpectedly. Noise level at maximum air flow is less than 80 dB. Length of air hose supplying Grade D breathing air is not stipulated, but the pressure of air at the inlet is required to be 85 psig for V4 FI and for V4 MTH2. Air flow can be adjusted by the user for his/her comfort, but cannot be shut off. In case of loss of air, the user can remove the mouth strip and move the opening close to his face, or enlarge the opening, to breathe outside air. Alternately, the user can pull the escape strip from either forearm, over the head and towards the other forearm, and rip the suit in two halves. This escape strip is normally used for egress from the suit when the work activity has been completed.

2.2.3 Implementation TXU Power has a respiratory protection program in full compliance with 10 CFR 20.

The Mururoa V4 F1 and V4 MTH2 suits will be integrated into TXU Power's respiratory program using the information provided by the manufacturer. New lesson plans will be developed to train workers on Mururoa's features, donning, use and removal, cautions, and use of mouth strip and tear off strips for routine and emergency egress. Radiation Protection personnel will be provided additional training on selection, approval, issue, equipment set-up, operation and maintenance instructions for the Mururoa suit.

Attachment toTXX-05163 Page 7 of 8 One deviation from the manufacturer's "M.T.H.2 Instructions for Use" (Attachment 8 to this submittal) is also requested. Under the "Dressing" section of the instruction, the manufacturer describes performing a visual inspection before removing the shipping protection (cardboard on the visor and inside the garment, and removable "plastic protection" from the visor)". TXU Power proposes to perform a visual inspection of the garment and its components afer the shipping protection material (cardboard and plastic protection) have been removed. This will allow removing the shipping protection material outside of a contaminated area and thus reduce potential radioactive waste.

According to the manufacturer's representative, both the cardboard and the plastic are only used to maintain the integrity of the visor, particularly during transit and storage.

This is done so that during the shipping process the visor does not become damaged, scratched or disfigured. The cardboard adds rigidity, and the plastic offers protection to the visor. Both must be removed prior to use of the suit.

The Mururoa suit's safety features, namely the tear-off mouth strip and the emergency tear-off strip, make it unnecessary for any standby rescue person. However, workers wearing air-supplied suits are typically under continuous surveillance by Radiation Protection technicians using remote video monitoring, or under direct Radiation Protection surveillance at the job location due to radiological conditions. Additionally, in many cases, workers are in direct contact with Radiation Protection and Steam Generator support personnel via audio headsets. The ability to eliminate the standby rescue person is also an ALARA consideration since the work areas where air-supplied suits are used are typically areas with higher radiation and contamination levels.

The Mururoa suits are single use only, and are not approved for use in atmospheres that are immediately dangerous to life and health (IDLH). TXU Power will discard each suit (other than those segregated for training purposes only) after one use.

Steam Generator platform work, reactor head work, cavity decontamination, and equipment decontamination are specifically targeted for the use of the Mururoa suit. TXU Power will use the site's Corrective Action Program to document any unexpected problems and track corrective actions taken. Problems associated with the suits will be communicated to the manufacturer to ensure that operating experience is shared with other users. A relationship with the manufacturer (or its representative) will also be developed that allows operating experience from other users to be incorporated into TXU Power processes. TXU Power will share this experience with the NRC and other utilities that may be interested in the Mururoa suit. Delta Protection has in place a vendor-user alert system so as to report any deviations, or deficiencies with the product and manufacturing process should they arise. The manufacturer is subjected to checks from the IPSN to insure the product has no risk of injury to the user. A second organization called ASQUAL performs annual inspections of the factory to certify that the product manufactured is of the same quality approved by the IPSN Notified Body. Several destructive/non-destructive tests are performed by the manufacturer for each order received from clients. Any defects reported by clients, investigations and corrective actions are documented. Customers are notified of any problems and products are recalled if necessary. This information is made available to ASQUAL for their annual inspections.

3.0 CONCLUSION

TXU Power requests authorization, pursuant to 10CFR20.1705, to use French designed respiratory equipment with an assigned protection factor of 5000. Based on reliable test information discussed earlier in this attachment, TXU Power has determined that the Mururoa suits offer a safer and more efficient means to protect workers in areas of high radiological contamination and in areas where there is a potential for airborne contamination. Pursuant to IOCFR20.1705, TXU Power requests authorization to use an assigned protection factor of 5000 with the Mururoa V4 F l and V4 MTH2 respiratory protection suits. Testing and associated manufacturer's documentation has shown that these suits provide design and protection considerations that support the requested assigned protection factor.

Made of non-flammable PVC sheet Its mechanical and chemical resistance Is good enough for working In most of the nuclear environments, acids, bases or low concentration solvents.

Caution should always be used around sharp edges and tools to avoid tearing of the Mururoa.

Contact with open flames or grinding spark ray for instance must be avoided to prevent perforation by melting of the PVC skin.

At any time: avoid direct contact with objects less than 5eC (41 0 F) or more than 600C (1401F) temperature. It Is the responsibility of the supervisor to qualify, by preliminary test, the ability of the suit to protect the wearer against the harmful atmosphere In each specific environment CAUTIONS

1) Care must always be taken due to the asphyxiation hazard.

2) The buddy system must be In effect with the use of this suit fed with a sufficient breathable air source with either both persons In it or the second person nearby In view with a particulate respirator ready.

3) Suit removal under ordinary circumstances requires an assistant.

4) Thorough knowledge of the safety features of the Mururoa are essential for safetyl a) a safety strip for breathing can be pulled open should air supply be restricted.

b) a safety strip for suit egress in an emergency is available by using pull tab on each elbow.

c) do not over tighten any tape applied to the suit as Itwill prevent rapid suit removal.

5) An air supply of 1 to 3 minutes exists Inside the suit should the air supply fall.

During that time, due to the magnetic exhaust valves, the garment will remain overpressurised, avoiding penetration of harmful atmospheres as long as portions of the remaining air have not been forced out of the suit such as if the wearer bends over and forces air out the discharge valves.
