RE(VEST FOR ADDITIONAL INFORMATION SUS(UEHANNA POWER UPRATE REVIEW 1.

The staff notes that different instrumentation is used for some functions than that discussed in NEDC-31336.

Therefore, please provide the following information:

a.

For the Barksdale BlT-M12SS-GE and B2T-M12SS-GE instruments; describe how instrument repeatability, static pressure, overpressure, and seismic effects are accounted for (and quantify if appropriate).

b.

For the Barton 228A instrument; describe how static pressure, overpressure, and seismic effects are accounted for (and quantify if appropriate).

2.

NEDC-31336, on page 4-40, states "Confirmation Ratios less than 1.0 indicate conformance."

However, page 1-7 of your setpoint submittal (PLA-3816) includes test interval data with confirmation ratios greater than 1.

Please explain:

a.

How outliers were treated in the determination of the drift rate for the Barton 228 switches.

b.

What is meant by the statement (page 1-5 of PLA-3816)

"D 8.74 psi; for conservatism and appropriate confirmation ratio, let Dl = 13.1 psi 3.

It is our position that Topical Reports that have not been reviewed and approved by the staff may be used as the basis for a licensing action.

GEITAS (cited on pages 1-2 and 2-2 of PLA-3816) is such a document.

Therefore,

please, provide a copy for our review.
