North Anna Nuclear Power Plant

Dear Commissioner Jaczko:

Today, I viewed the NRC webcast of the Commission and NRC Staff meeting with the licensee of the North Anna Nuclear Plant - in connection with the August 23rd, 2011, earthquake event which resulted in a ground acceleration beyond the plant's design basis and NRC license(s).

It.s of great concern that neither the Commission nor the Staff asked why the licensee would seek restart authorization from the NRC without inspection of the Unit-I internals. Apparently the licensee intends to rely on the inspection of the Unit-2 internals to justify the same for Unit-i; however, the NRC cannot accept the licensee's assertions that Unit-1 is bounded by inspection of Unit-2 internals to qualify the plant for NRC restart authorization. It is a matter of common sense and NRC regulations under 10 C.F.R. Part 100, Appendix "A" which requires the licensee's inspection of Unit-1 internals prior to the NRC granting the licensee restart authorization in these unprecedented circumstances.

To the extent that the licensee relied on seismic instrumentation installed in the base-mount area of the facility and had no "free-field" seismic instrumentation installed at the nuclear facility at the time of the earthquake event, the licensee's Cumulative Acceleration Velocity (CAV) measurements are not accurate and cannot be relied upon by the licensee nor the NRC in granting restart authorization.

Finally, because the licensee's CAV measurements are inaccurate; and because the facility experienced an earthquake event well-outside the plant's design basis and NRC license(s) - the license cannot present any measure of reasonable assurance to the NRC that the nuclear facility was not subjected to a ground acceleration event beyond the plant's safety margin. Therefore the nuclear facility remains in an unanalyzed condition for which the NRC lacks authority to grant restart authorization to the licensee in these circumstances.

In summary, any restart authorization granted to the licensee for the restart of the North Anna Nuclear Plant without requiring the inspection of the Unit-I internals; and a new seismic analysis of the nuclear facility -

would be an act in reckless disregard for the health and safety of the public which could very well result in a severe nuclear accident similar to the ongoing nuclear accident in Japan.

In closing, I will make myself available to the Commission in a public forum should the Commission desire to discuss these most serious nuclear safety issues further.
