The purpose of the telephone conference was to discuss outstanding NRC questions on the surcharging procedure submitted by Consumers Power Company to rectify the differential settlement between the BWST's and adjoining valve pits. A plan had been submitted to the NRC on June 26, 1981 and had been reviewed by Nuclear Reactor Regulation- (NRR) with the assistance of the U.S. Anny Corps of Engineers. During the course of the telephone con-i ference the following questions and requests for additional information l

were transmitted to the Consumers Power Company :

1.

The proposed procedure provided for monitoring and mapping l

of the existing crack (s). NRR requested the cracking inspec-l tion be conducted on a daily dasis. This plan must include what action will be taken upon discovery of new cracks or the l

widening of existing cracks.

2.

Consumers Power wis requested to provide elevations, which had been surveyed at the center of the BWST and at the edge I

(elevation of point at which the tank rests upon the ring 810813o071 eloy[9 in o W 2 at W d rane s kesses can M evaluated.

A print showing the relative elevations;and orientations nf the

. 3" and 4" lines (BWsT fill and drain lines) with respect to.the valve pit was requested by NRR. Constners Power' agreed to supply these prints.

4.

NRR raised the' question of what the maxista expected displace-ment of the valve pit would be under surcharging and what pro-cedural controls existed to suspend the loading in the' event that

-the maximum displacement was exceeded. Consumers Power. agreed to add provisions to the procedure to stop loading the valve pit-and perfonn an' engineering evaluation if the expected settlement of " was exceeded. NRR also reconnended using a plot of settle-ment vs. time during the surcharge period to determine if the settlement had stabilized under the planned incremental loading.

5.

NRR questioned the location of the benchmark to be used for measuring settlement. - Consumers Power agreed to describe to NRR what would be ~used as a reference benchmark.

Upon receipt of the above items, NRR agreed to assign a high priority to com-plating its review of the BWST surcharge plant, but this review is impacted by

.the demande for testimony preparation for the current ASLB hearing sessions.
