RE: OC LRI Daily Update 29 Sensitivity:

Confidential If I was successful with Outlook, then I've sent this message as CONFIDENTIAL When Michael said he "observed implementation of thickness gauging" ... What he didn't say, is that we have not witnessed any UT data taking inside the drywell (at any location).

Today, NDE techs were suppose to do UTs at 19 locations on the lowest level in the drywell (sandbed elevation).

This is a critical location for UT measurements.

Dose rates at this elevation are apparently high (Michael says 140 mr/hr ...he got 11 mr in 10 or 15 minutes).

Michael did observe NDE techs cal check their equip prior to entry, and did observe the techs trying to do a UT, but they weren't able to actually take any UT readings.

Michael saw them find the correct location, mind the match marks, prepare (clean) the surface, but the template didn't line up to the match marks, because of interference with caulk (a moisture barrier seal put on the floor curb last outage, after the UT had been done). Michael say no need to go back in to watch any UT data taking at that elevation, he's seen enough.Michael may observe some actual UT data taking at a few other locations within the drywell." Tim O'Hara will continue to follow the UT and VT activities in the sandbed (drywell external) tomorrow.Because of the schedule slips, and other problems with the NDE jobs, Tim will not be able to cover any of the UT work inside the drywell. Thursday (tomorrow) is Tim's last day on-site with us.Michael says he's willing to work the weekend, but doesn't think there's any reason to. Michael believes that we've seen enough to verify that they're implemented their commitment.

So we're really done with this portion of the 71003 inspection.

On an administrative note: Michael can't get pai{ (b)(6) and says he also can't get Comp Time.So, expecting him to work may not be fair.I hope to be back on-site mid to late Thurs afternoon.

2) Tim O'Hara entered one former sand bed bay today and performed a visual inspection finding everything to be satisfactory.

The applicant performed a visual inspection of the same bay and took ultrasonic thickness readings (the result are not yet available).

2) Dave Lew, and resident staff, entered the same bay today. They-expressed the opinion that conditions seemed satisfactory.

3)*Michael Modes accompanied NDE personnel to 11'3" elevation (drywell opposite the former sand bed) and observed implementation of thickness gauging. The licensee did not factor in the caulking placed on the curb-to-drywell joint after the last outage and the NDE technicians were unable to align the metal template with the center line. -arks on the drywell. Michael observed one trench free of water while accompanying the NDE personneL., P.rir to issuing a work request to remove the caulk in the way of the template the licensee had to be reminded, by the NRC, that they committed to an as-found visual inspection of the caulk. We anticipate a further delay as their try to schedule the inspection prior to their remediatiort.

4) John Richmond accompanied the technicians performing a structural insp§0etion of the inside of the circ water intake tunnel. John indicated the tunnel condition was good and he did not observe any exceptional conditions such as exposed rebar or flaking.5) Glenn Meyer, prior to his departure, observed the excavation of buried ESW pipe, noting that the pipe wrap was in good condition, and the pipe internal wall of a removed section had adequate remaining wall with no evidence of perforation, or excessive corrosion.

6) John Richmond independently verified the absence of water in the sand bed drain collection bottles after flood-up and observed an OC operator verifying the same.LR Commitment Issues or Concerns None.Drywell Structural Integrity Issues or Concerns None.NJ State Interface Congenial Team Location:
