All Attached please find the internal cover letter and report to the edo associated with the Byron and braidwood backfit appeal by Exelon associated with the funding of the PSVs during an inadvertent reactor overfill event.
This material, in my humble opinion, represents probably one of the best efforts I have read in recent memory with regard to an independent, thorough, and well supported positon.
The outcomes also appear to point to a growing problem with our decision making on issues, that is, at times, seeing things as we would like them to be given our current frame of reference and not necessarily seeking or obtaining sufficient understanding of the history that brought us here that, while different than our current desired state, may also be an acceptable answer.
The recommendation to the EDO is to overturn the proposed backfit.
Thanks and enjoyable reading.
Ken

[EDO Banner Update I a
&I Friday, September 16, 2016 rs1 Greetings!
I want to give you a brief update on a recent decision I made regarding the implementation of our backfit process. This process, which is described in 10 CFR 50.109 (and other analogous processes in our regulations), is meant to ensure that we have an appropriate basis if we need to change the careful, thorough, and technically solid findings we make in licensing nuclear power plants. For example, last week I shared with you some insights about our responsibility to assure adequate protection of public health and safety. This assurance can include the need to impose backfits in accordance with 10 CFR 50.109-as we did, for example, following the accident at Fukushima Dai-ichi.
Yesterday, I issued a final decision that supported a licensee appeal and overturned a backfit imposed by the Office of Nuclear Reactor Regulation (NRR). This backfit was issued in 2015 for the Byron and Braidwood nuclear plants in Illinois. Following our Management Directive 8.4 on backfits, I chartered a panel of senior technical and legal staff to consider the facts in this case and recommend a response. This panel reviewed over a hundred documents related to the plants' licensing basis and the history of
the technical issues in question and provided a detailed report.
The technical issue in this backfit is discussed in the panel's report. My decision was centered on the regulatory and legal issue of whether the "compliance exception" to the backfit rule's requirement to conduct a backfit analysis was properly applied.
In short, the staff needed to show that the initial approvals had been based on a mistake or omission, not that the interpretation of what was acceptable changed over time.
After considering both the panel's report and discussions I had with NRR staff who contributed to the backfit, I determined that the positions taken in the backfit were new or modified interpretations of what constitutes compliance in addressing potential pressurizer safety valve failures following water discharge, and did not provide a basis for a compliance backfit.
I recognize that we need to fully understand and disposition the technical concerns that underlie this backfit for the larger group of licensees to which they apply. Therefore, I have referred these technical issues to NRR for further assessment and have asked that a plan be provided within 120 days.
Although I decided to support the licensee's appeal in this case, I am proud to know that our people take seriously the responsibility for assuring public health and safety and are willing to pursue backfits, when appropriate. I encourage the staff to continue to raise issues of potential safety significance, adequate protection, and compliance.
R Victor Mccree, EDO
