COLUMBIA GENERATING STATION, DOCKET NO. 50-397 REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS WITH USE OF FRENCH-DESIGNED AIR-LINE RESPIRATOR EQUIPMENT

Dear Sir or Madam:

Pursuant to 10 CFR 20.1703, "Use of Individual Respiratory Protection Equipment," and 10 CFR 20.1705, "Application for Use of Higher Assigned Protection Factors," Columbia Generating Station (Columbia) is requesting authorization from the Nuclear Regulatory Commission (NRC) to use supplied-air containment suits as respiratory protection equipment with a higher Assigned Protection Factor (APF).

Columbia is specifically requesting authorization to: (1) use French-designed respiratory protection equipment that has not been tested and certified by the National Institute for Occupational Safety and Health; (2) not provide standby rescue persons whenever this equipment is used; and, (3) take credit for an assigned protection factor of 5,000 for this equipment. This request is based on the use of the Delta Protection Mururoa Supplied-Air Suits, models V4 F1 and V4 MTH2, since it has been determined that these suits have benefits associated with contamination control, heat stress reduction, and respiratory protection. provides the documentation supporting the request. As described in this enclosure, use of the Delta Protection suits would improve worker safety in areas of airborne radioactivity and in areas of high potential for facial/skin contamination from hot particles. describes the regulatory commitments Columbia has identified for use of the Delta Protection suits.

REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS WITH USE OF FRENCH-DESIGNED AIR-LINE RESPIRATOR EQUIPMENT Page 2 NRC approval is requested by February 12, 2007. This will allow Columbia to implement the procedure changes and complete training necessary for use of the Mururoa Supplied-Air Suits at their facilities prior to the Spring 2007 refueling outage.

If you have any questions or require additional information regarding the matter, please contact GV Cullen at (509) 377-6105.

1.0 INTRODUCTION

1.1 PURPOSE Columbia Generating Station (Columbia) has identified the Delta Protection Mururoa Supplied-Air Suits, models V4 F1 and V4 MTH2, as having benefits associated with contamination control, heat stress reduction, and respiratory protection. These suits do not have National Institute for Occupational Safety and Health (NIOSH) approval for use as a respirator to limit the intake of radioactive material in the United States. Therefore, pursuant to 10 CFR 20.1703(b), Columbia is submitting this application to the Nuclear Regulatory Commission (NRC) for use of equipment that has not been tested or certified by NIOSH to limit worker intakes. Additionally, since the Delta Protection suits do not have an NRC assigned protection factor (APF), pursuant to 10 CFR 20.1705, Columbia requests to use an APF of 5000. Due to the ease of removal and other features of the Delta Protection suits, Columbia requests confirmation that the 10 CFR 20.1703(f) requirement for dedicated standby rescue personnel would not apply while using Delta Protection suits to limit the intake of radioactive material.

The table provided in 10 CFR 20, Appendix A, "Assigned Protection Factors for Respirators," shows that an air-line suit may be used in a continuous-flow operating mode; however, an Assigned Protection Factor (APF) is not designated. A footnote to the table for this equipment application indicates that the suit can be used in a respiratory protection program if the minimum program requirements are met pursuant to 10 CFR 20.1703, "Use of Individual Respiratory Protection Equipment." 10 CFR 20.1703(b) states that use of equipment not tested or certified by the NIOSH is acceptable to limit the intake of radioactive material only if approved for use by the NRC. Since 10 CFR 20, Appendix A does not specify an APF for these air-supplied suits, 10 CFR 20.1705, "Application for Use of Higher Assigned Protection Factors,"

would have to be applied in order to obtain NRC approval for the utilization of an APF not provided by 10 CFR 20, Appendix A.

The Delta Protection Mururoa Supplied-Air V4 F1 and V4 MTH2 suits have been previously approved by the NRC with an APF of 5000 for use at other plants including the Constellation plants on January 19, 2006 (ML053570243), and the Diablo Canyon plant on December 21, 2005 (ML053340498). The Delta Protection suits have been widely used in western European nuclear power plants (the manufacturer indicates that approximately 60,000 Delta Protection suits are used by these plants each year). The suits received certification for use by the Institute for Nuclear Protection and Security (the European certifying agency which is comparable to NIOSH) in 1996.

1.2 BACKGROUND

1.2.1 Regulatory Requirements The following regulatory requirements are relevant to this request.

REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS WITH USE OF FRENCH-DESIGNED AIR-LINE RESPIRATOR EQUIPMENT Enclosure I Page 3 of 7 10 CFR 20.1703(a), "Use of Individual Respiratory Protection Equipment," states that if a licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material, the licensee shall use only respiratory protection equipment that is tested and certified by NIOSH, except as otherwise noted in this part.

10 CFR 20.1703(b) states that if the licensee wishes to use equipment that has not been tested or certified by NIOSH, or for which there is no schedule for testing or certification, the licensee shall submit an application to the NRC to authorize use of the equipment.

10 CFR 20.1703(f) requires the use of a standby rescue person whenever one-piece air-supplied suits are used which an unaided person would have difficulty extricating himself or herself.

10 CFR 20.1705, "Application for Use of Higher Assigned Protection Factors," requires that a licensee shall obtain authorization from the NRC before using assigned protection factors in excess of those specified in 10 CFR 20, Appendix A.

10 CFR 20, Appendix A, "Assigned Protection Factors for Respirators," Item II, "Atmosphere Supplying Respirators (particulate, gases and vapors)," indicates that for a suit in a continuous flow operating mode, no APF is assigned nor is a NIOSH approval schedule currently available for the evaluation of such 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.

Based on these regulatory requirements, Energy Northwest is required to obtain NRC approval for the (1) use of respiratory protection equipment that has not been tested or certified by NIOSH, (2) the assignment of a protection factor, and (3) to clarify that a standby rescue person is not required whenever these suits are in use.

1.2.2 Suit Construction The Delta Protection Supplied-Air Containment Suit meets International Organization for Standardization (ISO) 8194, "Radiation Protection - Clothing for Protection Against Radioactive Contamination - Design, Selection, Testing, and Use" and the European Standard EN 1073-1, "Protective Clothing Against Radiation Contamination."

The Delta Protection suits have the following desirable features (Attachments I and 2):

One-piece construction, that includes integral gloves and booties,

PVC (Fl) or Ethyfuge (MTH2) skin material with reinforced elbows, knees and crotch areas,

Dual zippers - metal zipper inside and plastic zipper outside,

Clear Poly Vinyl Chloride (PVC) helmet that provides distortion-free vision,

" Welded sleeve to insert communication cable,

REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS WITH USE OF FRENCH-DESIGNED AIR-LINE RESPIRATOR EQUIPMENT Enclosure I Page 4 of 7

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

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

" Air intake located at the waist with a built-in regulator that can adjust, but not block, airflow,

" Two exhaust valves that ensure the suit remains airtight should an event block/pinch the air supply line,

Low noise level,

" Air flow to arms, legs, and face.

Air hoses of any length can be used, but air shall be supplied to the Delta Protection suits at 85 psig +/- 10% measured at the inlet. A regulator at the inlet is used to adjust the airflow. To ensure user safety, the regulator cannot shut off the air supply. There are two patented exhaust valves on the back of the suit - one behind the neck and one at the lower back. The exhaust valves prevent any aspiration of contaminants if supplied air is lost.

The Delta Protection suits are approved for use with 16 different fittings in Europe and can be fitted with Schrader or Foster or CEJN type fittings used at the Columbia facilities.

1.2.3 Safety Features of the Delta Protection Supplied-Air Containment Suits In addition to the features described in Section 1.2.2, above, the Delta Protection Supplied-Air Containment Suits are lightweight (approximately 2 Ibs), and are available with a fire-retardant treatment. The Institute for Nuclear Protection and Security (IPSN) certifies the suit has the appropriate resistance to abrasion, flex cracking, puncture, tearing, and flammability. The noise level at maximum airflow is less than 80 dBa.

Airflow 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 the 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.

The Delta Protection suit's design does not permit its use in an Immediately Dangerous to Life and Health (IDLH) atmosphere. Columbia will use this suit for protection against radioactive particulate contamination, and will not allow use in an IDLH atmosphere.

1.2.4 Implementation Columbia has air-supplied hoods (commonly known as bubble hoods) for use on jobs involving overhead-contaminated water or high potential for skin contamination.

Because the bubble hoods do not cover the hands or feet, workers have to wear additional protective clothing to minimize potential skin contaminations in these areas.

The Delta Protection suits offer a better alternative (with their unitized construction and

REQUEST FOR USE OF HIGHER ASSIGNED PROTECTION FACTORS WITH USE OF FRENCH-DESIGNED AIR-LINE RESPIRATOR EQUIPMENT Enclosure I Page 5 of 7 ease of removal) and would protect the worker much better against facial/skin contamination and airborne radioactivity than the bubble hoods currently in use. Use of the Delta Protection suits would assist in Columbia's efforts to control contamination incidents and to prevent intakes during maintenance activities.

The Delta Protection suits will be integrated into the existing Columbia radiological respiratory protection program using the manufacturer's recommendations described in the "Mururoa V4 Fully Enclosed Suit - General Description" (Attachment 2), the "Instructions for Donning and Removal of the Mururoa V4 Fully Enclosed Suit" (Attachment 3), and the "Mururoa V4F1 and MTH2-V4 Instructions For Use" (Attachment 4). No exceptions will be taken with the minor clarification that the suits will be inspected and removed from their protective packaging outside of the plant's radiological controlled area in a way that maintains the integrity of the suit, but does not lead to the unnecessary generation of solid radioactive waste. Workers will be trained on the Delta Protection suit features, donning, use and removal, and use of mouth strip, and tear off strips for routine and emergency egress. Radiation Protection personnel will be trained on selection, approval, issue, equipment set-up, operation, and maintenance instructions for the Delta Protection suit.

The Delta Protection suits will be discarded after a single use and will not be used in IDLH atmospheres. Standby rescue personnel (i.e., 10 CFR 20.1703(f)) will not be used because the design of these suits provides for easy and effective self-rescue following a loss of supplied air.

Communication channels will be established between the manufacturer and Energy Northwest for the purpose of timely notification of significant problems that may affect suit safety, performance, or function. Any defects discovered will be entered into the Columbia Corrective Action Program and reported to the manufacturer. Industry notifications will be made through the Operating Experience Program.

2.0 TECHNICAL JUSTIFICATION 2.1 EVALUATION Columbia conducted an in-house inspection and demonstration of the suits. This inspection/demonstration indicated that the Delta Protection suits are an improvement over the currently used bubble hoods due to their ease in donning and removal.

Columbia also reviewed the following documents (Attachments) obtained from Delta Protection:

8481X1T for the EC Type Examination Certificate No. 0073/197/162/12/97/0028 (Attachment 9).

Based on a review of this documentation and the in-house inspection, the suits represent a better design than the currently approved bubble hood and provide better worker protection, with the data supporting an APF of at least 5000.

A key element of this review was the application of the European Standard and the Certificate issued by the Institute for Nuclear Protection and Security for the Delta Protection suits. The European Standard (Attachment 5) requires that the suit satisfy requirements associated with resistance to abrasion, flex cracking, puncture, blocking, 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. According to the testing standard, two workers should perform standard tests to determine the practicality of the suit. Standard tests include walking at a rate of 5 km/hr for 5 minutes and loading a bucket of chips from the base of a hopper and emptying it into the opening on top of the hopper repeated 15-20 times in 10 minutes. Additionally, a protection factor for the suit is determined. The testing standard requires two individuals to test two separate suits in a test chamber filled with sodium chloride.

The testing methodology includes the performance of a variety of exercises during the test. Certificate No. 0073/197/162/12/97/0028 (Attachments 8 and 9) states that the Delta Protection F1 suit passed in all categories tested and provided a fit factor of 50,000. Certificate No. 0073/197/162/01/96/0001 (Attachments 6 and 7) states that the Delta Protection MTH2 suit passed in all categories tested and provided a fit factor of 50,000. It should be noted that the term 'fit factor' used in the European Certificate is not the same as the Assigned Protection Factor used in 10 CFR 20. However, the testing associated with the granting of the Certificate supports the assignment of an Assigned Protection Factor (APF) of 5000 which is 10% of the documented fit factor.

The Delta Protection suit's safety features, namely the tear-off mouth strip and the emergency egress strip, allows the suit to be quickly removed making the assignment of standby rescue personnel unnecessary.

J PAGE :1/4 MURUROA SUIT The Mururoa suit is a single use garment designed to be used in radioactively contaminated environments. It has been widely used in western European Nuclear Power Plants for more than 20 years, without any major problem (the French state company: Electricit& de France use

'60,000 garments each year).

The Mururoa suit is a fully enclosed PVC plastic, supplied-air and pressurized suit, that offers excellent protection factor ( -100,000) against any solid, liquid, or gas pollutant, minimizing discomfort and heat stress and increasing the worker's efficiency.

The Mururoa suit is C.E. approved and complies with CE standard EN:1073-1 "Protective clothing against Radioactive Contamination" It also fulfils the requirements of the I.S.O. 8194 standard "Radiation Protection-Clothing for protection against Radioactive contamination-Design selection ,testing and use"

- An airflow control valve, preset to a minimum flow of 250 litres/minute (9 CFM) at 3 bar (42 PSIG), located on the right hip and covered with a protection flap. This flow can be adjusted, from 250 to 1150 litres (9 CFM to 41 CFM) per minute. 1150 litres is obtained with the tap fully opened at the feeding pressure of 6 bar (85 PSIG) (refer to graph in annex 11).

- A silencer bag which attenuates the noise level less than 58 dBa at 250 litres/minutes to 76 dBa at 1150 litres/minute.

- A manifold system welded to the suit and distributing the air to the helmet, the legs and the arms.

An exhaust by two world patented valves placed in the helmet and in the back. These valves ensure a remarkable airtight seal in case of accidental air-feed cut off, or when putting the suit in under pressure through abrupt movements. The valves regulate the overpressure in the garment between 3 mbar (0.042 PSIG) and 10 mbar (0. 142 PSIG) for supply air pressure between 3 bar (42 PSIG) and 6 bar (85 PSIG)

The benefits of this system are High heat removal through superior airflow

- Non irritating diffuse ventilation

- Resistance free breathing

- High level of comfort for long and strenuous jobs in contaminated areas

- Very low noise level

FOREWORD The Mururoa suit is a fully enclosed supplied-air suit; designed for protecting the wearer against radioactive contamination brought about by contact with liquid or solid substances or by atmospheric pollutants such as solid particles, mist gases or vapors.

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. 0 0 At any time: avoid direct contact with objects less than 5°C (410F) or more than 60 C (140 F) 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 safety!

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 thesuit as it will prevent rapid suit removal.

5) An air supply of I to 3 minutes exists inside the suit should the air supply fail.

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.
