Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 1
1.0 INTRODUCTION
Arizona Public Service Company (APS) is the licensee of the Palo Verde Nuclear Generating Station (PVNGS). APS is aware of the advantages in the radiological, personnel cooling, and respiratory protection afforded by use of Mururoa single-use, supplied-air suits (Models MTH2 and V4F1) (subsequently, this equipment") to persons working in areas of airborne radioactivity.
From an evaluation of the applicable regulations, APS concludes that an application to the Nuclear Regulatory Commission (NRC) is necessary. This application must include:
Request for authorized use of this equipment.
Request for the authorized use of an assigned protection factor for this equipment.
Consideration of the need for a standby rescue person.
Evidence of the equipments performance and capability for worker protection.
A list of commitments from the licensee regarding use of this equipment and training of personnel.
The NRC has found similar proposals from numerous other licensees to be acceptable, as documented in Safety Evaluations [References 17, 18, 19, 20, 21, 22, 23, and 24 for Duke, Entergy, Florida Power and Light Company (FPL), Union Electric Company, Pacific Gas and Electric Company (PG&E), Constellation Energy Generation Group, Progress Energy, and DTE Electric Company (DTE), respectively].
This equipment was originally manufactured by Delta Protection, a Bacou Dalloz Company; however, since 2013, they have been manufactured by Honeywell Safety Products, Inc. As previously reported to NRC by Southern Company (Reference 25),
the change in manufacturer does not impact the manufacturing form, fit, or function of the suits.
APS anticipates using this equipment within a viable, ongoing respiratory protection program for the PVNGS site.
To meet regulatory requirements for use of this equipment, APS proposes to revise certain aspects of the respiratory protection program. These proposed actions are captured in associated Regulatory Commitments described in Table 1 of this Enclosure.
2.0 REGULATORY EVALUATION
Title 10 of the Code of Federal Regulations (10 CFR) Part 20, Standards for Protection Against Radiation, Subpart H, Respiratory Protection and Controls to Restrict Internal Exposure in Restricted Areas, concerns the use of respiratory protection equipment for protections against airborne radioactive materials.
Section 20.1703, Use of individual respiratory protection equipment, paragraph (a),
requires that respiratory protection equipment used by a licensee to limit the intake of radioactive material be tested and certified by the National Institute for Occupational Safety and Health (NIOSH). Section 20.1703(b) states that a licensee
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 2
shall submit an application to the NRC for authorized use of respiratory protection equipment that has not been tested and certified by NIOSH.
Appendix A to Part 20, Assigned Protection Factors for Respirators, does not provide an assigned protection factor (APF) for atmosphere supplying respirator suits in a continuous-flow operating mode. Instead, it references footnote (g) that 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., §20.1703).
Section 20.1705, Application for use of higher assigned protection factors, states that a licensee shall obtain NRC authorization before using assigned protection factors in excess of those specified in Appendix A to Part 20. The application is required to describe the situation for which a need exists for higher protection factors and to demonstrate that the respiratory protection equipment provides these higher protection factors under the proposed conditions of use.
Therefore, based on the above requirements, APS must obtain approval for the use of this equipment and for the associated use of an assigned protection factor.
Section 20.1703(f) requires that standby rescue personnel be provided whenever respiratory protection equipment from which an unaided individual would have difficulty extricating himself or herself is used.
3.0 TECHNICAL JUSTIFICATION According to the guidance provided in Section 4.12.1 of Regulatory Guide 8.15, Acceptable Programs for Respiratory Protection (Reference 6), and Section 4.10.3 of NUREG/CR-0041, Manual of Respiratory Protection Against Airborne Radioactive Material (Reference 7), the NRC believes that, in certain nuclear industry applications, supplied-air suits might be the best overall choice, considering respiratory protection, contamination control considerations, heat stress, and trying to maintain worker dose as low as reasonably achievable (ALARA).
3.1 Explanation of Why Existing NIOSH-Certified Equipment Does Not Meet Identified Need According to the guidance in Section 4.2 of Regulatory Guide 8.15 (Reference 6), an application to use a noncertified device should explain why no existing NIOSH-certified device meets the licensee's need.
APS has identified a need for a respiratory protection device that is not NIOSH-certified. APS believes there are advantages in the respiratory protection afforded using Mururoa single-use, supplied-air suits, Models MTH2 and V4F1, to persons working in areas of airborne radioactivity. APS is interested in both models due to supply chain flexibility considerations. The two models are identical in all respects other than material of construction. Model MTH2 is made of Polyethylene (Ethyfuge) while Model V4F1 is made of Polyvinyl Chloride (PVC).
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 3
In the area of respiratory protection, APS believes that the Mururoa supplied air suits give a well-defined advantage over other NIOSH certified products by providing a substantially higher APF. Other NIOSH certified respirators have APFs ranging from 10 (for tight fitting half face negative pressure respirators) to 10,000 [for pressure demand Self Contained Breathing Apparatus (SCBA)]. Testing shows that the Mururoa supplied air suits offer APFs of up to 100,000. This equates to a demonstrable increase in worker respiratory protection.
In the area of worker protection from radioactivity, APS believes that the Mururoa supplied air suits offer a distinct advantage in improved worker safety in areas of airborne radioactivity and high potential for facial/skin contamination from hot particles over other methods that would utilize NIOSH approved products and separate clothing combinations. APS believes that the fully encapsulating aspect of the Mururoa supplied air suits provide less risk of particle penetration.
In the area of contamination control, APS believes that the Mururoa supplied air suits offer reduced risk of cross contamination during undressing/exit from a contaminated area over other NIOSH approved products due to their unitized construction and ease of removal. APS believes that this provides a better alternative for protecting the worker from facial/skin contamination and airborne radioactivity.
In the area of heat stress prevention, APS believes that the Mururoa supplied air suits offer a clear advantage over other NIOSH approved products. APS believes that the fully encapsulating aspect of the Mururoa supplied air suits provide greater whole-body cooling compared to other NIOSH approved products that would provide airflow over the head area only.
In the area of emergency response, APS believes that the Mururoa supplied air suits offer improved worker safety as compared to other NIOSH approved products. The design of the Mururoa supplied air suits offer quick self-extrication without the need for additional personnel. And, unlike other respiratory protection products, as the suit is entirely pressurized it provides several minutes of breathable atmosphere in the event of equipment failure.
APS believes that all these aspects combine to keep workers dose, standby personnels dose, and emergency response personnels dose ALARA in all situations.
3.2 Material and Performance Characteristics Relative to Anticipated Condition of Use Pursuant to 10 CFR 20.1703(b), the application must include evidence that the material and performance characteristics of the equipment can provide the proposed degree of protection under anticipated conditions of use. Section 20.1703(b) further states that this must be demonstrated either by licensee testing or based on reliable test information.
According to the guidance provided by Section 4.2 of Regulatory Guide 8.15 (Reference 6), an application to use a noncertified device should also show that using the device as proposed will not subject the wearer to undue physical or psychological stress or undue hazard. The guidance in Section 4.2 of Regulatory Guide 8.15 further states:
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 4
When the NRC has granted authorization to use such a device to one licensee, subsequent applications by additional licensees may make use of test information in that original submittal.
3.2.1 Test Information for Certification by the Institute of Nuclear Protection and Security To meet the requirements of 10 CFR 20.1703(b), APS provides the following Attachments to this
Enclosure:
- provides a general description of the Mururoa supplied air suits
- provides a copy of EN 1703-1, Protective clothing against solid airborne particles including radioactive contamination - Part 1: Requirements and test methods for ventilated protective clothing against particulate radioactive contamination
- provides the test results and subsequent certification of the Mururoa MTH2 suit
- provides additional test results performed by the manufacturer with more detailed test results on the protection factor determined during the fit test for the MTH2 suit
- provides the test results and subsequent certification of the Mururoa V4F1 suit
- provides additional test results performed by the manufacturer with more detailed test results on the protection factor determined during the fit test for the V4F1 suit
- provides manufacturers instructions for proper use of the supplied air suits.
Specific results were presented for: abrasion resistance, puncture resistance, tear resistance, flammability, inward leakage average-Fit Factor, seam resistance, vision distortion, pressure in suit, carbon dioxide content in inhalation air, and noise level.
The testing concluded that:
MURUROA MTH2: Upon presentation of the test results, the ventilated suit-pressurized for a single use only, MTH2 - ref 841 442 T is certified to ensure a protection against radioactive contamination according to the following specified limits:
o Minimum air flow rate: 30 m3/h (500 L/min) o Maximum air flow rate: 66 m3/h (1,100 L/min)
MURUROA V4F1: Upon presentation of the test results, the ventilated suit-pressurized for a single use only, MURUROA V4F1 - ref 848 1X1T is certified to ensure a protection against radioactive contamination according to the following specified limits:
o Minimum air flow rate: 27 m3/h (450 L/min) o Maximum air flow rate: 64.2 m3/h (1070 L/min)
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 5
Although the testing provides a minimum and maximum air flow rate, neither the MTH2 nor V4F1 suits are manufactured with a low air flow rate indicator. To ensure adequate airflow, APS proposes to regulate the air pressure supplied from the distribution manifold in accordance with the manufacturers instructions, such that the air supplied to the suit inlet is consistent with the conditions for which this equipment was certified. As proposed, the regulation of the air supply for this equipment would be operationally similar to the existing practice for NIOSH-certified equipment.
3.2.2 Anticipated Conditions of Use The PVNGS anticipated conditions of use are:
Single use only. This equipment is intended for single use only (i.e., disposed of after one use).
Radiological Contamination/Airborne Radioactivity. This equipment is intended for use in areas of high radiological contamination and/or areas with high airborne radioactivity.
Not in environments Immediately Dangerous to Life and Health (IDLH). This equipment is not intended for use in environments that are considered IDLH, as defined in 29 CFR 1910.134(b) Respiratory protection, Definitions (Reference 4) and as clarified in the guidance in Section 6.8 of Regulatory Guide 8.15 (Reference 6) for the resolution of minor difference between NRC and OSHA respiratory protection requirements. As defined in 29 CFR 1910.134(b):
Immediately dangerous to life or health (IDLH) means an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual's ability to escape from a dangerous atmosphere.
According to the guidance provided in Section 6.8 of Regulatory Guide 8.15, the term IDLH does not realistically apply to airborne radioactivity but could apply to certain nonradiological hazards at an NRC-licensed facility, in which case OSHA rules apply. Such nonradiological hazards include oxygen-deficient environments (e.g., inerted structures and vessels), chemical hazards (e.g.,
chlorine, hydrazine), and firefighting.
Use without a designated standby rescue person. Pursuant to 10 CFR 20.1703(f), standby rescue persons are required whenever one-piece atmosphere-supplying suits, or any combination of supplied air respiratory protection device and personnel protective equipment are used from which an unaided individual would have difficulty extricating himself or herself. Based on the safety features built into this equipment, APS proposes to use this equipment without the standby rescue persons described by 10 CFR 20.1703(f). The NRC has found similar proposals from numerous other licensees to be acceptable, as documented in Safety Evaluations (References 17, 18, 19, 20, 21, 22, 23, and 24 for Duke, Entergy, FPL, Union Electric Company, PG&E, Constellation Energy Generation Group, Progress Energy, and
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 6
DTE, respectively). The relevant safety features which obviate the need for a standby rescue person include:
o An egress strip stretching from left arm, over the head, to right arm that is normally used for undressing and can be used for self-rescue during an emergency, such as loss of supplied air; o
A removable strip covering an opening near the mouth that could be used for emergency breathing in case of loss of supplied air; o
Two exhaust valves that provide ventilation, and protect from overpressure; and o
Air intake located at the waist with a built-in control valve that can adjust, but not block, air flow.
The General Description (Attachment 1) and the Instructions for Use (Attachment 7) provided by the manufacturer indicate that emergency egress takes less than 3-5 seconds while, in case of an air supply failure, this equipment remains pressurized for a few minutes.
3.3 Need/Use of Higher Assigned Protection Factor Pursuant to 10 CFR 20.1705, a licensee is required to obtain authorization from the Commission before using APF greater than 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.
Authorization to use a higher protection factor is requested because this type of equipment is listed under II.1 (i.e., Atmosphere supplying respirators - Air line respirator - Suit) in Appendix A to 10 CFR Part 20 with no assigned protection factor.
APS requests authorization to use an APF of 5,000 for this equipment. The NRC has found similar proposals from many other licensees to be acceptable, as documented in Safety Evaluations (References 19, 20, 21, 22, 23, and 24 for FPL, Union Electric Company, PG&E, Constellation Energy Generation Group, Progress Energy, and DTE, respectively). As APS uses contractors during outages at PVNGS that have worked at other sites and potentially used this equipment, consistency is an important consideration in maintaining worker safety.
According to the guidance provided in Section 4.12.2 of Regulatory Guide 8.15 (Reference 6), if a licensee needs to apply for an APF to a supplied-air suit, the conditions of use to be described in the written application would include the anticipated length of air supply hose (minimum and maximum) and breathing air supply pressure (minimum and maximum). The NIOSH approval criteria for supplied-air hoods (42 CFR Part 84 Approval of Respiratory Protection Devices) may be useful to licensees who anticipate applying for use of an APF for supplied-air suits.
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 7
The certification process for this equipment did not include consideration for the length of air supply hose and breathing air supply pressure. Section 3.4 describes an alternative to ensure that the air supplied to the suit inlet is consistent with the conditions for which this equipment was certified.
3.4 Demonstration of the Higher Protection Factor Under Proposed Conditions of Use As documented in Attachments 3 and 5, this equipment was tested and certified for a fit factor of 50,000 based on European Standard CEN/TC 162 N 738. As documented in Attachments 4 and 6, the manufacturer estimates the actual protection factor at approximately 100,000 or more. Consequently, use of an assigned protection factor of 5,000 is conservative.
However, the approach taken to establish the conditions for testing and certification under European Standard CEN/TC 162 N 738 is different from that taken by NIOSH.
As described in Section 3.2.1, this equipment was certified for a range of air flow being supplied to the inlet of this equipment at about 85 psig. For the Mururoa supplied air suits, the certificate concluded that the user would have a device to check for achieving the minimum air flow rate. In contrast, the NIOSH approach, as expressed in Section 4.18.2 of NUREG/CR-0041 (Reference 7) for supplied-air respirators, is:
NIOSH approvals for SARs [supplied-air respirators] require that a minimum airflow be delivered to the respiratory inlet covering.... The certifications are written, however, so that the end user of the respiratory device is not required to measure the actual flow rate of air delivered to the device. Rather, an acceptable pressure range at the distribution manifold is specified for a given length of hose, number of hose sections, or for a specified number of quick-connect fittings.... Licensees are never required to measure the flow rate of air supplied to a facepiece or hood.
As stated in Section 3.2.1, APS does not intend to provide the user with a device to check for the minimum air flow rate. Instead, APS proposes to regulate the air pressure supplied from the distribution manifold such that the air supplied to the suit inlet is consistent with the conditions for which this equipment was certified. As proposed, the regulation of the air supply for this equipment would be operationally similar to the existing practice for NIOSH-certified equipment currently in use.
From a practical standpoint, the maximum and minimum hose lengths and maximum and minimum air supply pressures for this equipment may be limited by the need to interface with existing respiratory protection equipment which is NIOSH-certified. In Table 8, Air Supply Line Requirements and Tests (42 CFR Part 84, Subpart J), the maximum and minimum lengths of hose are listed as 300 feet and 25 feet, respectively, for NIOSH certification of Type C supplied-air respirators. The maximum pressure would be limited to 125 psig at the inlet of the hose connection by 42 CFR 84.148(b) for Type C supplied-air respirator, continuous flow class.
To establish the conditions at the distribution manifold necessary to ensure that the air supplied to the suit inlet is consistent with the conditions for which this equipment
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 8
was certified, APS proposes to establish a range of pressures for various lengths of hoses that will ensure the wearer receives the specified air flow rates.
APS further proposes to incorporate into the respiratory protection program specific instructions for use of this equipment. This proposal to test and document is identified as a Regulatory Commitment in Table 1.
3.5 Implementation and Maintenance of the Respiratory Protection Program According to Note g to Appendix A of 10 CFR 20, atmosphere supplying respirators-air line respirator-suits 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., § 20.1703).
APS implements and maintains a viable, ongoing respiratory protection program pursuant to the requirements of 10 CFR 20.1703 at PVNGS. Currently, the program only permits the use of respiratory protection equipment that has been tested and certified by NIOSH, pursuant to the requirements of 10 CFR 20.1703(a).
After NRC authorization under 10 CFR 20.1703(b) to use this equipment and prior to actual first use, APS proposes to modify, consistent with the Instructions for Use (Attachment 7) provided by the manufacturer for this equipment, the respiratory protection program as necessary to meet the minimum program requirements of 10 CFR 20.1703, except for fit testing. This proposal is identified as a Regulatory Commitment in Table 1.
Many elements of the respiratory protection program are generically applicable and will not require change. The following discussion addresses those elements of the respiratory protection program that will require change:
3.5.1 Written Procedures Regarding Supervision and Training of Respirator Users Pursuant to 10 CFR 20.1703(c)(4)(ii) and the guidance provided in Section 4.12 of Regulatory Guide 8.15, APS proposes to revise or develop written lesson plans to train workers on the features of this equipment; how to don, use, and doff this equipment; and instructions on using the built-in escape strips for routine and emergency egress conditions. The proposed training will include appropriate hands-on and classroom instruction. APS proposes to conduct specific training on actions to be taken by the user in the event of equipment malfunction. APS further proposes to provide appropriate training to personnel responsible for implementation of the respiratory protection program to assist in selection, issuance, set-up, and operation of this equipment.
3.5.2 Written Procedures Regarding Respirator Selection Pursuant to 10 CFR 20.1703(c)(4)(iv) and the guidance provided in Section 4.12 of Regulatory Guide 8.15 (Reference 6), APS proposes to revise or develop written procedures to provide guidance on respirator selection. Written guidance is proposed to include:
This equipment is designated for a single use (to be discarded after one use).
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 9
This equipment is not intended for use in environments that are immediately dangerous to life and health (IDLH), such as oxygen-deficient environments (e.g., inerted structures and vessels), chemical hazards (e.g., chlorine, hydrazine), and firefighting. Contact with open flames or grinding/welding sparks is prohibited.
The assigned protection factor for use with this equipment is 5,000.
To provide the 6 Bars (about 85 psig) air supply pressure to the inlet of this equipment, as specified by the manufacturer in Instructions for Use (Attachment 7), the setup of the pressure at the distribution manifold needs to be appropriate for the pressure drop in the combination of hose length and number and type of connections that is used.
This equipment may be used without a standby rescue person.
3.5.3 Written Procedures Regarding Storage, Issuance, Maintenance, Repair, Testing, and Quality Assurance of Respiratory Protection Equipment Pursuant to 10 CFR 20.1703(c)(4)(vii) and the guidance provided in Section 4.12 of Regulatory Guide 8.15 (Reference 6), APS proposes to revise or develop written procedures consistent with the conditions for which this equipment was certified and in accordance with manufacturer's recommendations in the "Instructions for Use" (Attachment 7). Written guidance is proposed to include:
This equipment has a shelf-life of three (3) years from date of manufacture when stored in the original packaging, out of the light, in a temperature between 41°F and 113°F.
Because this equipment is designated as single use, there is no maintenance or repair.
Consistent with the guidance in Table 4-21 of NUREG/CR-0041 (Reference 7),
this equipment need not be routinely inspected when stored in the packaging as received from the manufacturer. Testing is limited to an inspection at or near the time of issue and an operational check by the user after donning and before exposure to airborne contaminants.
Consistent with the guidance in Section 4.13.2 of NUREG/CR-0041, the inspection will check for tears and defects in fabrication material, presence of zippers as required, and integrity of heat-sealed seams and air distribution and exhaust systems. An operational check for the correct functioning of the supply flow valve and the over pressure valves can be accomplished by crouching down rapidly a few times.
APS notes that the NRC authorized FPL (Reference 19) a minor clarification in the process for removal of the protective packaging and inspection of this equipment to avoid the unnecessary generation of solid radioactive waste. APS may implement a similar clarification to the manufacturer's Instructions for Use (Attachment 7) if necessary to avoid similar concerns.
3.6 Respirator Problem Identification and Communication As described in Section 4.9.2 of NUREG/CR-0041 (Reference 7), the NIOSH approval process includes a problem-investigation program, in which reports of problems received from regulatory agencies, labor organizations, respirator users, and respirator manufacturers, are investigated and resolved. Items of major interest or
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 10 significance are widely distributed as Respirator User Notices or Respirator User Warnings. That program is described in Chapter 6, Section F, of Department of Health and Human Services (NIOSH) Publication 87-116, NIOSH Guide to Industrial Respiratory Protection (Reference 8).
Since this equipment is not certified by NIOSH, the NIOSH program described in NUREG/CR-0041 for problem-investigation would not be applicable to this equipment.
Instead, after NRC authorization under 10 CFR 20.1703(b) to use this equipment and prior to actual first use, APS proposes to revise the respiratory protection program to use the existing Corrective Action Program to provide appropriate guidance for communicating identified problems with this equipment to the vendor and the rest of the nuclear industry. The Corrective Action Program is credited with meeting the requirements of 10 CFR 50, Appendix B, Criterion XVI, but is also normally used to identify and resolve a wider range of problems and enhancements. This proposal is identified as a Regulatory Commitment in Table 1.
3.7 Conclusions Pursuant to 10 CFR 20.1703(b), APS is applying for NRC authorization to use respiratory protection equipment that has not been tested and certified by NIOSH, specifically Mururoa single use, supplied-air suits (Models MTH2 and V4F1) at the PVNGS site. Pursuant to 10 CFR 20.1705, APS is also applying for NRC authorization to use an assigned protection factor of 5,000 for this equipment. As documented in Safety Evaluations (References 19, 20, 21, 22, 23, and 24 for FPL, Union Electric Company, PG&E, Constellation Energy Generation Group, Progress Energy, and DTE, respectively), the NRC has found applications from other licensees with similar requests to be acceptable. Based on the safety features of this equipment, APS is proposing to use this equipment without the standby rescue persons described by 10 CFR 20.1703(f).
APS has explained why existing NIOSH-certified respiratory protection equipment does not meet an identified need. The explanation is consistent with information in relevant NRC guidance documents and in similar applications from other licensees.
APS has enclosed information provided by the manufacturer relative to the material and performance characteristics of this equipment. Previously docketed test information from the manufacturer, from the European testing and certifying agency, and from other licensees has been enclosed or referenced as reliable evidence that the material and performance characteristics of this equipment can provide the proposed degree of protection under the anticipated conditions of use. The information shows that use of this equipment will not subject the wearer to undue physical or psychological stress or undue hazard.
Noting that no assigned protection factor is listed in Appendix A to 10 CFR Part 20 for this type of equipment, APS has described a situation for which a need exists for a higher assigned protection factor. Previously docketed test information from the manufacturer and from the European testing and certifying agency has been enclosed to demonstrate that the respiratory protection equipment conservatively provides the higher protection factor under the anticipated conditions of use. To ensure that the air pressure supplied to the suit inlet is consistent with the conditions for which this equipment was certified, APS has established Regulatory Commitments, as listed in
Enclosure INFORMATION TO SUPPORT APPLICATION FOR AUTHORIZED USE OF MURUROA SINGLE-USE, SUPPLIED-AIR SUITS, MODELS MTH2 AND V4F1 11 Table 1, to establish pressure ranges for various hose lengths that are representative of those anticipated to be used.
APS implements and maintains a viable, ongoing respiratory protection program at the PVNGS site. To use this equipment appropriately within the existing respiratory protection program, APS has established Regulatory Commitments, as listed in Table 1, to make changes to address training, storage, setup, discard after single use, prohibition from use in an environment that is immediately dangerous to life and health, inspection, testing, and respirator problem identification and communication.
4.0 PRECEDENTS As previously noted, Mururoa suits have been widely used in western European nuclear power plants as well as many plants in North America as documented in Safety Evaluations [References 17, 18, 19, 20, 21, 22, 23, and 24 for Duke, Entergy, FPL, Union Electric Company, PG&E, Constellation Energy Generation Group, Progress Energy, and DTE, respectively].

(I, 04 66 89 lS 36 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: Electricite 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 ls 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"

o:- 04 66 89 18 36 PAGE :2/5 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 betw~en 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

- 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, if used, the MURUPHONE system, or other communication device 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 + 5°C and + 45°C.( 41 °F and 113°F)
USAGE The air supply should be between + 15°C and + 45°C. (59°F and 113°F)
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.
