1.0 INTRODUCTION
1.1 Purpose 10 CFR 20, 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 to this equipment application indicates that the suit can be used in a respiratory protection program if the minimum program requirements are meet (e.g., 10 CFR 20.1703, "Use of Individual Respiratory Protection Equipment"). 10 CFR 20.1703 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 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 exercised in order to obtain NRC approval for exceeding the requirements of 10 CFR 20, Appendix A.
PPL Susquehanna, LLC 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 2000 when using the suits. Additionally, due to the advanced safety features for emergency breathing and emergency escape built into these suit models, PPL Susquehanna, LLC 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 2000 (TAC NOS.
MB7952, 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.
10 CFR 20.1703, "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.
Enclosure to PLA-5834 Page 2 of 6 10 CFR 20.1703(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.
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 (i.e., 10 CFR 20.1703).
Based on these regulatory requirements, PPL Susquehanna, LLC 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 desirable features that are not available in the "bubblehoods" and "rain suits" manufactured in the United States:
- 1) One piece single use suit that includes welded gloves and booties with tie straps,
- 2) Made of Ethyfuge 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, but not block, airflow,
- 9) Two exhaust valves that provide ventilation, and also protect from overpressure,
Enclosure to PLA-5834 Page 3 of 6
- 10) Very low noise level at maximum air flow, and
- 11) Air flow 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 measured at the inlet. 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 or Foster or CEJN type fittings used at the PPL Susquehanna, LLC 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 All Mururoa suit models are lightweight (2.5 lbs.), 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. PPL Susquehanna, LLC 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.
Enclosure to PLA-5834 Page 4 of 6 1.2.4 Implementation PPL Susquehanna, LLC sites have respiratory programs in full compliance with 10 CFR 20. The Mururoa V4 MTH2 suits will be integrated into the PPL Susquehanna, LLC 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. Undervessel activities such as CRD and LPRM exchange, reactor cavity decontamination, and equipment decontamination are specifically targeted for the use of the Mururoa suit.
PPL Susquehanna, LLC will use the Corrective Action Program (CAP) to document and evaluate any unexpected problems with the suits. 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.
PPL Susquehanna, LLC currently uses air- supplied hoods, (commonly known as the bubble hood) for jobs involving overhead 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 two 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 2000 for the Mururoa suits would allow use of the Mururoa suits in PPL Susquehanna's, LLC efforts to control contamination incidents and prevent intakes during operational activities at all of the PPL Susquehanna's, LLC facilities.
Enclosure to PLA-5834 Page 5 of 6 2.0 TECHNICAL JUSTIFICATION 2.1 Evaluation PPL Susquehanna, LLC reviewed the following documents obtained from Delta Protection:
- General Description of the Mururoa Model V4 MTH2 Ventilated Suits (Attachment 5.1),
- European Standard EN 1073-1:1998 for Ventilated Protective Clothing (Attachment 5.2),
- Certificate No. 0073/197/162/01/96/0001 for Mururoa Model V4 MTH2 Issued by the Institute for Nuclear Protection and Security (Attachment 5.3),
- Protection Factor Determined During Fit Test Exercises for Mururoa Model V4 MTH2 (Attachment 5.4), and
- Donning and Removal Instructions for Mururoa V4 MTH2 (Attachment 5.5).
Based on a review of this documentation, 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 2000.
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 5.2) 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 5.3) 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
Enclosure to PLA-5834 Page 6 of 6 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.
PPL Susquehanna, LLC 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 2000 for the Duke Energy Corporation in June 2003 (TAC NOS. MB7952,
- MB7953, MB7954, MB7955, MB7956, MB7957, and MB7958).
3.0 CONCLUSION
PPL Susquehanna, LLC requests the approval for the use of the suits as per 10 CFR 20.1703(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, PPL Susquehanna, LLC 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 nearly impossible, 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 minimizes the potential for personnel contamination events.

- 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
