NRC STAFF AFFIDAVIT OF ABDUL H. SHEIKH CONCERNING INTERVENORS MOTION TO AMEND MOTION FOR ADMISSION OF CONTENTION NO. 5 Abdul H. Sheikh does hereby state as follows:
- 1. I am employed as a Senior Structural Engineer in the Division of License Renewal (DLR), Office of Nuclear Reactor Regulation (NRR), U.S. Nuclear Regulatory Commission (NRC). A statement of my professional qualifications is attached. For the past 33 months, I have been responsible for the review and onsite audit of the structural portion of license renewal applications. In this capacity, I have performed audits and reviewed license renewal applications for 17 nuclear power plants, including Davis-Besses. Specific areas of review include nuclear power plant structures, including containments and shield building. I have also reviewed the licensees analyses and evaluations to address the effects of laminar cracking in the existing Shield Building, at Davis-Besse Nuclear Power Plant.

(Agencywide Documents Access and Management System (ADAMS) Accession No. ML12058A249).
Attachment C
- 3. I have reviewed Intervenors Motion and the attachment thereto, in which Intervenors seek to amend their proposed Contention 5, which they submitted on January 10, 2012. 2
- 4. In this declaration, I present my views with respect to the issue raised in item 1.
of Intervenors Motion. 3 In that item, Intervenors claim that there is new information related to their proposed new Contention No. 5. Specifically, Intervenors contend that the NRC required FirstEnergy to assume, in its calculations of the strength of the wall, that the vertical outer rebar mat did not even exist. 4
- 5. The NRC Staff did not require FirstEnergy to assume in its calculations of the strength of the wall that the vertical outer rebar mat did not exist. Instead, FirstEnergy developed calculations and the NRC Staff reviewed them.
- 6. Moreover, FirstEnergys calculations did not remove the shield buildings entire vertical rebar mat. Instead, based on extensive field investigations, FENOC conservatively considered rebars in the following areas of the shield building as ineffective: (1) the top 20 feet of shield building near spring line 100 percent of the outside hoop and vertical rebars, (2) at the interface between the shield building shell and each of the 16 architectural flute shoulders (vertical strips of approximately 10 foot wide) 100 percent of the outside vertical and 50 percent of the outside hoop rebars, (3) around the two main steam line penetration 100 percent of the outside hoop rebar within the middle 6 foot high region, and 50 percent of the outside hoop rebars beyond the middle 6 foot high region, and (4) around the two main steam line penetration 100 percent of the outside vertical rebars.
