- 1. §20.1703(b) requires prior authorization from the Nuclear Regulatory Commission (NRC) for the use of equipment that has not been tested or certified by National Institute for Occupational Safety and Health (NIOSH).
- 2. §20.1705 requires prior authorization from NRC before using assigned protection factors in excess of those specified in §20, Appendix A.
Model V4 MTH2 provides for better worker protection in areas of airborne radioactivity and in areas of high potential for facial or skin contamination from hot particles. Other benefits include improved contamination control, reductions in heat stress, and better respiratory protection over existing equipment. Model V4 MTH2 has no current NIOSH approval for use as a respirator in the United States; therefore, TVA requests that the NRC review this special equipment for approval for respiratory protection and also assign a protection factor for its use. The enclosure to this letter provides TVA's detailed "Request for Approval."

1.0 INTRODUCTION
1.1 PURPOSE 1 OCFR20, Appendix A, "Assigned Protection Factors for Respirators," states that an air-supplied suit may be used in a continuous-flow mode; however, an Assigned Protection Factor (APF) has not been designated. A footnote (g) to this equipment application indicates that the suit can be used in a respiratory protection program if the minimum program requirements are met (e.g., 10CFR20.1703, 'Use of Individual Respiratory Protection Equipment). 10CFR20.1703 states that use of non-National Institute for Occupation Safety and Health (NIOSH) equipment is acceptable only if approved for use by the Nuclear Regulatory Commission (NRC). Since 1 OCFR20, Appendix A does not specify an APF for these air-supplied suits, 10CFR20.1705, "Application for Use of Higher Assigned Protection Factors," would have to be exercised in order to obtain NRC approval for exceeding the requirements of 10CFR20, Appendix A.
Tennessee Valley Authority (TVA) proposes the use of the Mururoa "fully enclosed suit" model V4 MTH2 manufactured by Delta Protection, France. The purpose of this submittal is to request approval for the use of these particular suits and for authorization to use an APF of 2,000 when using the suits. Additionally, due to the advanced safety features for emergency breathing and emergency escape built into these suit models, TVA may choose to use the Mururoa suits without dedicated rescue personnel being assigned.
The Mururoa suit was accepted by the NRC in June 2003 for use by the Duke Energy Corporation as a respiratory device with a protection factor of 2,000 (TAC NOS. MB 7952, MB7953, MB7954, MB7955, MB7956, MB7957, and MB7958). The Mururoa suits have been widely used in Western European nuclear power plants (the manufacturer indicates that approximately 60,000 Mururoa garments/suits are used by these plants each year). The suits received certification for use by the Institute for Nuclear Protection and Security in 1996.
1.2 BACKGROUND
1.2.1 Regulatory Requirements The following regulatory requirements are relevant to this request.
10CFR20.1703, "Use of Individual Respiratory Protection Equipment," requires that if a licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material, (a) the licensee shall use only respiratory protection equipment that is tested and certified by NIOSH.
10CFR20.1703(b) allows 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.
10CFR20.1705, '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 1 OCFR20, Appendix A.
Page 3 of 12 10CFR20, 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 (i.e., 10CFR20.1703).
Based on these regulatory requirements, TVA is required to obtain NRC approval for both the use of and a protection factor for the Mururoa model V4 MTH2 suit.
1.2.2 Suit Construction The Mururoa Model V4 MTH2 suit meets ISO 8194 and the European Standard EN.NF 1073-1. The manufacturer is ISO 9002 certified.
The Mururoa single use suits have the following features that are not typically available in the "bubblehoods" and "rain suits" manufactured in the United States and currently in use at TVA:
- 1)
One piece single use suit that includes welded gloves and booties with tie straps
- 2)
Made of polyethylene (Ethyfuge 2000) with reinforced elbows, knees and crotch areas
- 3)
Dual zippers - metal zipper inside and plastic zipper outside
- 4)
Helmet made of clear Poly Vinyl Chloride (PVC) material that provides distortion-free vision and large enough for wearing a headset
- 5)
Welded sleeve to insert communication cable
- 6) A removable strip near the mouth that could be used for emergency breathing in case of loss of supplied air
- 7)
An egress strip stretching from left arm, over the head, to right arm that is used for undressing and for self-rescue in an emergency, such as loss of supplied air
- 8) Air intake located at the waist with a built-in regulator that can adjust airflow (but not block it).
- 9) Two exhaust valves that provide ventilation and protect from overpressure
- 10) Very low noise level at maximum air flow
- 11)
Air flow distributed to the arms, legs, and face Air hoses of any length can be used, but air shall be supplied to the Mururoa suits between 40-85 psig as measured at the inlet.
Page 4 of 12 A regulator at the inlet can adjust the airflow from 43 CFM maximum to 9 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 airflow to 58 dB at minimum airflow. 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 lower back. The exhaust vents have patented magnetic seals to prevent any aspiration of contaminants if supplied air is lost. The Mururoa is approved for use with different fittings in Europe and can be fitted with Schrader, Foster or CEJN type fittings used at the TVA facilities. The Mururoa Model V4 MTH2 suit is made of Ethyfuge material, which is incinerable. Examination of the suit shows there are two air vents near the chin for cooling the face, as well as a distribution network for air to go to the arms and the legs.
1.2.3 Safety Features of the Mururoa Model V4 MTH2 Suit The Mururoa suit is lightweight (2.5 Ibs), made of fire-retardant material and can be used in temperatures up to 1400 F., as per EN 1073-1. The suits have built-in gloves, booties with binding ties, and have reinforced elbows, knees and crotch. A transparent helmet with 6-inch X 8-inch clear faceplate provides distortion-free view. Dual magnetic ventilation valves provide needed ventilation and relief of excess pressure in case suit is squeezed/pinched unexpectedly. Noise level at maximum airflow is less than 80 dB.
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 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.
The Mururoa suit's design does not permit its use in an Immediately Dangerous to Life and Health (IDLH) atmosphere. TVA plans to use this suit for protection against radioactive particulate contamination only. 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.
1.2.4 Implementation TVA sites have well developed respiratory programs in full compliance with 10CFR20.
The Mururoa V4 MTH2 suits will be integrated into the TVA respiratory program using the information provided by the manufacturer. New lesson plans will be developed to train workers on the 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 for selection, approval, issue, equipment set-up, operation, and maintenance instructions for the Mururoa 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 personnel. Additionally, in many cases, workers are in direct contact with Radiation Protection or support personnel via audio headsets.
The ability to eliminate the rescue worker is an ALARA consideration since the work areas where air-supplied suits are used are typically areas with higher radiation and contamination levels. Steam generator platform work, reactor cavity decontamination, and equipment decontamination are specifically targeted for the use of the Mururoa suit.
Page 5 of 12 TVA will use the Corrective Action Program (CAP) to document and evaluate any unexpected problems with the suits. In addition, TVA will advise Delta Protection of any unexpected problems with the suits, if they arise. The manufacturer is subjected to checks from the IPSN (Institute for Nuclear Protection and Security) to insure the product has no risk of injury to the user. A second organization called ASQUAL (an advisory group to regulators) performs annual inspections of the factory to certify that the manufactured product is of the same quality approved by the IPSN. 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 by Delta Protection, and are reported to licensees using our suits on a quarterly basis. Customers are notified of significant problems and products are recalled if necessary. This information is made available to ASQUAL for their annual inspections.
TVA currently uses air-supplied hoods, (commonly known as the bubble hood) for jobs involving overhead contamination, contaminated water, high potential for skin contamination from discrete radioactive particles, and to prevent intake of airborne contaminates. Because the bubble hoods do not cover the hands and the feet, workers have to wear additional protective clothing, including multiple pairs of gloves, rubber shoes and booties and tape for sealing. Chances of cross contamination during undressing/exit from the contaminated areas are high. The Mururoa suits offer a better alternative (with their unitized construction and ease of removal) and should protect the worker much better against facial/skin contamination and airborne radioactivity.
Approval of a protection factor of 2,000 for the Mururoa suits would allow use of the Mururoa suits in TVA's efforts to control contamination incidents and prevent intakes during operational activities at the TVA's nuclear facilities.
2.0 TECHNICAL JUSTIFICATION 2.1 EVALUATION TVA reviewed the following documents obtained from Delta Protection:
General Description of the Mururoa Model V4 MTH2 Ventilated Suits (Attachment 1)
European Standard EN 1073-1:1998 for Ventilated Protective Clothing (Attachment 2)
- Certificate No. 0073/197/162/01/96/0001 for Mururoa Model V4 MTH2 Issued by the Institute for Nuclear Protection and Security (Attachment 3)
Protection Factor Determined During Fit Test Exercises for Mururoa Model V4 MTH2 (Attachment 4)
Donning and Removal Instructions for Mururoa V4 MTH2 (Attachment 5)
Based on a review of this documentation and physical examination of the Mururoa Model V4 MTH2 suit, the suits represent a better design than the currently approved "bubble hood" and "rain suit" combination and provide better worker protection with the data supporting an APF of 2,000.
C.
Page 6 of 12 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 Mururoa suits. The European Standard (Attachment 2) requires that the suit material be tested for 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, three workers should perform standard exercises, each wearing two different suits inside a chamber filled with a test agent (Sodium Chloride) and measure the leakages during the exercise regimen lasting 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 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 air flow rates. Certificate No. 0073/197/162/01/96/0001 (Attachment 3) states that the Mururoa Model V4 MTH2 passed in all categories tested and provided a protection factor greater than 50,000. It should be noted that the term 'protection factor' used in the European Standard is equivalent to the 'fit factor' used 10CFR20.1003 and is not the same as the Assigned Protection Factor used in 10CFR20 Appendix A.
TVA also conducted an in-house inspection and demonstration of the suits. This inspection/demonstration indicated that the Mururoa suits are an improvement over the currently used suits due to their ease in donning and removal.
Additionally, the NRC approved the use of the Mururoa Model V4 MTH2 suit with an APF of 2,000 for the Duke Energy Corporation in June 2003 (TAC NOS. MB 7952, MB7953, MB7954, MB7955, MB7956, MB7957, and MB7958).
3.0 CONCLUSION
TVA requests the approval for the use of the suits as per 10CFR20.1703(a), which requires use of respiratory protection equipment that is tested and certified by NIOSH or alternatively which is approved for use by the NRC. Based on in-house inspection of suits and review of industry and manufacturer test documentation, TVA has determined that the Mururoa V4 MTH2 model air supplied suits offer a safer and more efficient means to protect workers in areas of either high radiological contamination and/or high potential for airborne contamination. The existing rain suits and bubble hoods provide cooling only to the head and force workers to wear the ensemble in a manner that makes self-rescue very difficult, thus requiring a rescue worker to be stationed nearby.
Ease of removal of the Mururoa suit provides for more desirable self-rescue features.
Additionally, the Mururoa suits provide a means to undress that minimize the potential for personnel contamination events.

PAGE :2/4 VENTILATION / EXHAUST In the supplied-air Mururoa suit, the ventilation system is composed of 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

NO/841 442T INDICE: e M.T.H..2 DATE: 12/00 PAGE: 1/1 INSTRUCTIONS FOR USE Preliminary remarks: This clothing is to be used under the authority of the person responsible for issuing the equipment for its dedicated use:
- the clothing offers the necessary protection for it's intended use.
- Breathable air *network, hoses with connectors compatible with that of the clothing, are actually available on site and that they are capable of supplying a sufficient quantity of air:
minimum flow rate 500 liters/min. +/-10% at 6 Bars; (17 cfm at 85 psig) maximum flow rate 1100 liters/min. +/- 10% at 6 Bars; (38cfm at 85 psig)
DRESSING
- The wearer, with a helper, visually inspects the condition of the garment and its components, then removes the shipping protection (cardboard on the visor and inside the garment, and removable 'plastic protection" from the visor).
- He enters through the rear opening of the garment and insures that his legs are in the garment.
- Connects to the breathable air network by passing the supply line through the loop at the rear of the garment, at the same height as the supply valve.
- Connects,a communication device, if applicable, through the safety loop and communication loop and finishes dressing.
- The helper zips up the dual zipper system and applies a large strip of adhesive tape to the upper extremity of the second zipper at the top to ensure air tightness. He then, ties the over boot laces around the ankles.
- The wearer can control the air supply by turning the adjustment knob. The correct functioning of the supply flow valve and the over pressure valves can be verified by crouching down rapidly a few times.
- He then is free to enter the work zone.
UNDRESSING
- Undressing may be done in the following manner. While the garment is still being supplied with air, the helper pulls on the orange undressing strip, which runs from one wrist to the other over the hood. Once the undressing strip is removed, the helper can split the suit shell by pulling on the hooded area and separating the suit into two identical pieces. The helper rolls up the front and rear parts in a way that traps the contamination and avoids all contact with the wearer of the garment. (Please consult our video for detailed undressing techniques).
IMPORTANT
- Leave the work zone immediately if the clothing deflates during the work phase evolution.If the helmet fogs, or if the person has a feeling of excessive warmth.
- Remember that the clothing remains pressurised for a few minutes in case of an air supply failure STORAGE In the original packaging; out of the light; between + 5C and + 45°C.( 41eF and 113'F)
USAGE The air supply should be between + 15'C and + 45°C. ( 59°F and 11 37F)
EXPIRY DATE The clothing should be used by the third year from the date of manufacture.
CLEANING Not necessary for this type of equipment which is for a single use only.
EMERGENCY FEATURES
- Air outside of the garment can be breathed by removing the safety strip at the front of the helmet/hood.
- The undressing strip, removed by the wearer, enables the wearer to self escape t in less than 5 seconds.
' Breathable air: see the EN 132 standard.
