Davis Besse Shield Building: Technical Review Discussion Items Elba Pass on to technical reviewers.
Thanks Jim 1
Davis-Besse Shield Building Laminar Cracking Licensee had extended discussions today with Professor Darwin.
Professor Darwin could not support an analytical determination of rebar splice strength in presence of a laminar crack. Basically, the licensee needs to identify sufficient uncracked zones at top of shield building so bond at rebar splices can be credited as effective.
Licensee plan going forward [1900 on 11/15/2011]:
" Lower portion of shield building- vertical rebar controls - seismic
" Upper portion of shield building - circumferential rebar controls - thermal loads
" Perform additional IR / core bore mapping at top of shield building to identify uncracked concrete areas
- Demonstrate effective circumferential rebar is adequate for design loads. This will be somewhat subjective since actual splice locations are not known and licensee has indicated rebar mapping is ineffective.
- New design basis calculations:
o At bottom: make sensitivity calculation that removed rebar in shoulder regions a design basis calculation o At top: based on IR / core bore mapping, show that circumferential rebar connectivity is sufficient to demonstrate adequate load capacity for design loads NRC technical reviewer challenges:
" Is licensee's proposed success path a viable solution
" How to define good concrete areas
- What portion of the shield building requires good concrete for sufficient bond strength at splices o Portion of splice in crack zone vs installed splice overlap length o Even though rebar splices are staggered, basis to credit load transfer of failed splice to adjacent rebar NRC reviewers need to come to a consensus: is licensee's proposed success path a viable solution to identified circumferential cracking
