OC LR Commitment Problems I informed AmerGen [Cal Taylor] today that we are reviewing 2 specific LR commitments, to determine whether AmerGen adequately implemented those two commitments.

(1) SER Commitment 27, ASME Section Xl, Subsection IWE. Item (2), A strippable coating will be applied to the reactor cavity liner to prevent water intrusion into the gap between the drywell shield wall and the drywell shell during periods when the reactor cavity is flooded.

AmerGen was asked to provide the following information

> Performance of the strippable coating during the two previous outages (2006 & 2004)

> Any condition reports (CRs), issue reports (IRs), or action requests (ARs) associated with the strippable coating from the 2006 outage (2) SER Commitment 27, ASME Section XI, Subsection IWE. Item (3), The sand bed region drains will be monitored daily during refueling outages.

AmerGen was asked to provide their basis to conclude this commitment had been adequately satisfied, in light of the following

> Sand bed drains were monitored by checking poly bottles, attached to the drain lines by tygon tubing. The drain lines could not be directly observed.

> After the cavity was drained, 2 of 5 tygon tubes were found to be disconnected and laying on the floor.

> Sand bed Bay 11 drain line poly bottle was empty during each daily check until Nov 15 (cavity was drained on Nov 12), when it was found full (> 4 gallons). Bay 11 was entered, visually inspected, and found dry. AmerGen believes that the 4+ gallons had been held up in the catch funnel (not directly, observable). This implies that the Bay 11 drain line had not be draining into the poly bottle for some period of time.

In addition, I asked AmerGen to Schedule an Exit Meeting on either Dec 3 or 4, and provide any feedback as to whether they prefer a telephonicexit or an in-person exit meeting.

Thanks John R.
