REQUEST FOR ADDITIONAL INFORMATION SURRY POWER STATION, UNITS I AND 2 (TAC NOS. M98382 AND M98383);
NORTH ANNA POWER STATION, UNITS I AND 2 (TAC NOS. M98384 AND M98385)
"10 CFR 20.1703(a}(2} EQUIPMENT AUTHORIZATION" I.
In the March 27, 1997 request letter for the 10 CFR 20.1703{a){2) authorization, Virginia Electric and Power Company {VEPCO) requested to
".* make allowance for protection factors as specified for Pressure-Demand Self-Contained Breathing Apparatus {SCBA) in 10 CFR 20, Appendix A {i.e., 10,000 or greater) during normal and emergency use."
In reference to the numerical value of the SCBA protection factor {PF) 10,000 or greater, please confirm that you are requesting to use protection factors greater than 10,000. Since 10 CFR 20 Appendix A requires prior authorization to use PFs greater than 10,000, please
- provide additional test data for PFs greater than 10,000 to justify use of such PFs.
- 2.
In attachment 1 of the submittal, the SCBA maintenance program for the "containment-use only" {CUO) units is described mainly in general terms.
The staff needs more details about CUO SCBA maintenance.
- a.
The site maintenance procedures and SCBA maintenance worker training program are "in ~ccordance with MSA's [Mine Safety Appliances]
training, and preventive maintenance and repair procedures." Please confirm if these vendor procedures are generic to open-circuit SCBAs, or are they specific for the CUO units. Also please describe aspects of the maintenance procedures and training programs which are specific to the CUO units and which differ from the generic MSA maintenance procedures and training program. This description should include different techniques {e.g., how to keep a hydrocarbon-free environment), routine inspection frequencies {e.g.,
0-rings for regulator, steel cylinder hydrostatic tests), or other routine maintenance activities.
- b.
Do the maintenance surveillance activities for SCBA units differ depending on whether brass or aluminum alloy components are used?
If not, justify why not and provide a detailed maintenance/
surveillance/inspection summary of any experience with CUO SCBAs
{using enriched oxygen) with non-brass parts. The test data submitted in Attachments 2 and 3 of your March 27, 1997 request focused on catastrophic SCBA failures, while this question is directed at a program for assessing chronic degradation {e.g.,
accelerated corrosion) of aluminum alloy parts and material used in an e~riched oxygen environment.*
- 3.
Relative to the requirements of 10 CFR 20.1703{a){3){v) {medical fitness evaluation), describe any special, additional information provided to ENCLOSURE
- the medical doctor for an evaluation of *a worker who enters containment using an SCBA.
If no special distinction is made among SCBA users, then justify why not, given the challenging containment environment.
Have any site workers been approved for routine SCBA use, but not for in-containment _use? If so, give the percentage of rejected versus approved workers.
- 4.
Relative to the user fit testing requirements, -what pass-fail criteria is used to ascertain an acceptable fit? The NRC staff finds the guidance in 288.2-1992 acceptable -- for a positiv~-pressure, tight-fitting respirator, a fit factor of at least 100 should be obtained.
What percentage of fit-testers for SCBA use have failed the existing site's fit testing criteria?
- 5.
The CUO SCBAs are intended to be available for "emergency use."
Does this include in-containment firefighting? If so, what prevents the temperature "limit" of 135 degrees Fahrenheit {to prevent possible 0-ring failures during initial regulator startup) from being exceeded in containment?
