Overview and Background
- New Replacement Steam Dryers (RSDs) will be installed in all three Browns Ferry Units
- To resolve any issues that existing steam dryers may have under EPU conditions
- Previous submittals, now withdrawn, had over 260 RAIs associated with steam dryers
- New EPU License Amendment Request (LAR) submittal will address previous issues , look to minimize RAIs, and support NRC approval
- Current strategy and design complies with existing and contemporary regulatory requirements
- Contracted with GEH to build our RSDs as they are the Original Equipment Manufacturer and have experience in other recent RSDs
- We are here to present an overview of our RSDs design, analysis, monitoring plan and inspection plan with an expectation that NRC fully understands the RSD information we plan to submit as part of our EPU LAR
- Presenter is Pete Donahue, Senior Manager for EPU Engineering
- Supported by GEH personnel l 3

BFN Replacement Steam Dryer
- Based on the curved hood six bank prototype replacement dryer first used in a BWR/4 reactor.
- Design is significantly more robust than the original steam dryer it replaces.
- BFN acoustic load definition developed using MSL acoustic pressure measurements taken at the three Browns Ferry units.
- The FIV fatigue evaluation and primary stress methodologies used for BFN RSD analysis has been reviewed in detail on BWR/6 RSD and ESBWR projects.
- Analyzed for the applicable primary structural loads for normal operation and for transient and accident conditions.

BFN RSD Inspection Plan
- During the first two scheduled refueling outages after reaching EPU conditions, a visual inspection will be conducted on the replacement steam dryer for each unit.
The inspection plan will be consistent with the industry guidance. The inspection plan will include all accessible exterior and interior critical locations identified in the vibration and stress analyses for the Browns Ferry RSDs.
