Chairman Jackson's CoNm'ents on SEC 119 I approve the requested action to publish the proposed regulation to modify the power reactor reporting requirements in 10 CFR 50.72 and 50.73. I recognize that the proposed chany;c constitute an overall significant improvement to the reactor reporting requirements which should result in higher quality licensee reports. Promulgation ci the regulation guidance in parallel with
. the rule publication for comment will ensure valid public feedback is received.- I commend the staff for proposing rule language that is moro risk-informed, simpler, and more logically arranged. Additionally, changes to allowed reporting times appropriately correspond with the NRC need for the information.
However, the staff should carefully consider public comments on the new requirement to report j
component problems that significantly degrade the ability to fulfill a safety function and that could j
reasonably be expected to affect other similar components in the plant. I recognize the staff 1
desire to ensure valid component problem data continues to be provided to the NRC, but this
- change defines a new (and not very clear) threshold for reporting that will be subject to varying interpretations by licensees and inspectors. Similarly, the continued use of terms such as "significant" and " seriously degraded" will cause interpretation problems to remain (even though examples have been provided).
l The staff should also consider expanding the applicability of the proposed change to limit written reports to only those occurring within the last three years. This change was only applied to two of the written reporting criteria, creating ar. :.. casistency with the remaining criteria (that j
will have no historical bound). The staff should consider the staff need for reports on historical problems and consider applying this change to other criteria for consistency.
