In addition, SNC requests an Assigned Protection Factor of 2000 associated with the use of the MURUROA BLU Suit Systems. These suits have been identified as having benefits from a contamination control, heat stress reduction, and respiratory protection point of view. SNC has previously received approval for use of the MURUROA V4F1 and MTH2 with an assigned protection factor of 5000. Upon approval, these suits will be included as an option in the SNC respiratory protection program for all three SNC plant sites. Enclosure 1 provides documentation supporting this request for the MURUROA V4F1 R. Enclosure 2 provides documentation supporting this request for the MURUROA MURUROA BLU Suit Systems. Enclosure 3 describes activities that SNC has identified for use of these suits. These actions will be completed prior to use. The actions are captured in the SNC Corrective Action Program to assure and track implementation. U. S.

With regard to the MURUROA V4F1 R were accepted by the NRC on August 14, 2006, and October 2006, use by Entergy as a respiratory with an of 5000 Agency-wide Documents Access and Management (ADAMS) Accession No. ML062230266 ML062230281, respectively}. Also, the V4F1 R suit was approved by NRC for use by Turkey Point Units 3 and Lucie Units 1 and 2, Seabrook Duane Arnold Center, and Beach Units 1 and 2 by NRC Safety Evaluation (SER) dated August 31, 2009 (Ref. Accession No. ML092310030). Furthermore, the MURUROA suits have widely used in western European nuclear power plants (the manufacturer indicates that approximately 60,000 MURUROA garments/suits are by these plants each year) as well as plants in North America. 1.2 BACKGROUND 1.2.1 Regulatory Requirements proposes to use model V4F1 R manufactured by Delta Protection. The pu rpose of this is to approval use of this particular suit for authorization to use an of 5000 when using this suit. The following regulatory requirements are relevant to this 10 20.1703(a), "Use of Individual Respiratory Protection Equipment," states that if a licensee or permits the use of protection equipment to limit the intake of radioactive material, "the shall use only respiratory protection equipment that is tested and certified by NIOSH, as otherwise noted in this part." 10 20.1703(b) that if licensee use equipment that has not been tested or certified by NIOSH, or for which there is no for Assessment of MURUROA V4F1 R Supplied Air Suits Enclosure 1 testing or certification, the shall submit an application to the NRC to authorize use of the equipment exceot as provided in part. 10 CFR 20.1703(f) requires use of a standby rescue person whenever one~ piece are which an unaided would have difficulty extricating himself or herself. 10 CFR 20.1 "Application for of Higher Assigned Protection requires that a licensee shall obtain authorization from the NRC before using assigned factors in excess of those specified in 10 CFR 20, Appendix A. 10 CFR 20, A, "Assigned Protection Factors for Respirators," Item II, "Atmosphere Supplying Respirators (particulate, 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 This equipment may be used in an acceptable respiratory protection program as long as all other minimum program requirements, with the exception of fit testing, are 10 CFR 20.1703). Based on regulatory SNC is to obtain NRC approval for the use aSSigned protection factor for the MURU ROA model R suit. 1.2.2.
