Enclosure to NRC-15-0046Response to Request for Supplemental Information Enclosure toNRC- 15-0046Page 1Response to Request for Supplemental InformationBackgroundOn February 12, 2015, DTE Electric Company (DTE) submitted a request for authorization foruse of the MURUROA supplied air suits, Models MTH2 and V4F 1, and the MURUROA BLUSuit Systems, which have not been tested or certified by the National Institute for OccupationalSafety and Health (NIOSH). On March 30, 2015, the U.S. Nuclear Regulatory Commission(NRC) requested that DTE provide additional information regarding the minimum supplied inletair pressure to the MTH2 and V4F1 suits or revise the scope of the application regarding inlet airpressure to the suits. NRC requested that DTE "provide reliable test information thatdemonstrates that the MTH2 and V4F 1 will provide adequate air pressure to the suits sufficientto meet the minimum air flow and [carbon dioxide] C02 build up limits of the [European Union]EU certification standard" or "revise the scope of the application to be within the test dataprovided."ResponseIn accordance with NRC's request, DTE is revising the scope of the application to be within thetest data provided regarding inlet air pressure to the MTH2 and V4FI suits. This changecomplies with the manufacturer's instructions. This change will revise the first paragraph onPage 4 of Reference 2, Enclosure 1, Section 1.2.2 to state:Air hoses of any length can be used, but air shall be supplied to the suits at85 PSI (6 bar). A regulator at the inlet is used to adjust the airflow. Toensure user safety, the regulator cannot shut off the air supply. There aretwo patented exhaust valves on the back of the suit, one behind the neckand one at the lower back. The exhaust valves prevent any aspiration ofcontaminants if supplied air is lost.The last paragraph in Reference 2, Enclosure 1, Section 1.2.4 on page 5 will be revised to state:DTE will follow the manufacturer's instructions for use ensuring that theminimum operating air pressure and airflow is being supplied to the suitprior to working in them, specifically ensuring that the minimum pressurewill be monitored during regular use. Air hoses of any length can be used,but air shall be supplied to the MURUROA MTH2 and V4F1 at 85 PSI (6bar). A regulator at the inlet can adjust the air flow. To ensure usersafety, the regulator cannot shut off the air supply. The maximum noiselevel is kept between 76 decibels (dB) at maximum air flow and 58 dB atminimum air flow.}}
