Singal, Senior Project Manager Balwant.Singal@nrc.gov Christopher Newport, Senior resident Inspector, Diablo Christopher.Newport@nrc.gov John P. Reynoso, Resident Inspector, Diablo John.Reynoso@nrc.gov FROM: Jane Swanson, Spokesperson San Luis Obispo Mothers for Peace janeslo@icloud.com Upon reading ML17086A013 (see attached) San Luis Obispo Mothers for Peace (MFP) has a number of questions. Given that Balwant Singals name is given as the person to whom PG&Es Chief Nuclear Officer is invited to address questions, I also address MFP questions to him, as well as to the Resident Inspectors. I will appreciate responses from one or more of you in order to help MFP better understand the meaning of this document.

On page 2 of the attachment under 3.1 it is stated that both welds were examined in the 19th refueling outage. That outage concluded in June of 2016. Do I understand correctly that the welds in question were thoroughly examined at that time?

In section 3.3 are statements about ultrasonic examinations covering 63% and 52% of welds.

Is the impracticality referred to in this document defined by the fact that, when in operating mode, it is impossible to access the welds in the way they can be accessed during an outage?

Will the welds be inspected during future outages? If so, during what month/s would such inspections take place?

Section 3.5 seems to be an admission that the design of the seal injection filter vessel is faulty.

The NRC staff concludes that therefore it is an unreasonable burden on the licensee to make them examine those welds.

Mothers for Peace suggests that rather than offering bad design as an excuse, the fundamental problem should be addressed. Redesign and replace in the interest of public safety. The risks to workers at Diablo and the general public must outweigh the "burden upon the licensee."

I look forward to your responses.
