In Its July 21 2013 license amendment applcation, OPPD described installing physical protection against tornadoes for cer-tain equipment During equipment Installation and associated reviews of the existing licensing basis and discussions with the NRC staff, OPPO determined that it needed to request the amendment described above. OPPD explained that It did not submit the amendment sooner because it had not previously concluded that prior NRC approval was required. OPPD noted Kiley Petersen, being duly sworn, deposes and says that he/she is an employee of that these tivities changes required must befrom to recover obtained to support an extended plant an outage, startup and that entended delaydueIn to the activity a key comrplexwould and Integrated nature ofadverse have a cascading, the ac-impact on the resumption of operations.

An "exigent" amendment reduces the time the public and State have to comment on the associated issue of "no significant hazards Register, consideration" and allows for notice to be provided through local media (e.g., a newspaper) instead of through the county of Douglas and State of Nebraska, and of general circulation in the Federal 10 CFR SO.w1(a)(6)(l)?r).
The Commission's regulation at 10 CFR 50.gtta)(t) requires that, at the time a licensee requests an amendment, the licensee Counties of Douglas, and Sarpy and State of Nebraska, and that the attached must provide to the C;ommission the lcensee's analysis about the issue of no significant hazards consideration using the standards In § 50.92, whIch concern whether the proposed hO amendment (1) involves a significant Increase in the probability or consequences Responseof an accident poreviously evaluated: or (2) creates the possibility of a new or different kind of accidennt printed notice was published two times in the said newspaper the first insertion from any accident previously evaluated: or (2) involves a significant reduction In a margin of safety.
