20555 May 29, 1981 IE Circular No. 81-08:
FOUNDATION MATERIALS Descriotion of Circumstances:
Insufficient compaction of foundation and backfill materials during the con-struction of nuclear plants has resulted in excessive settlement of plant structures at a number of sites.
At the Midland Plant, Units 1 and 2, insufficiently compacted backfill was discovered as a result of excessive settlement cf the diesel generator build-ing. The results of extensive-subsurface investigations subsequent to settle-ment of the diesel generator building identified that fill materials beneath portions of the auxiliary building, feecwater Isolation valve piti, essential service water intake structure, barated water storage tanks, and plant area utilities were not compacted to specification requirements.
Other specific nuclear power plant sites and identified problems are list'ed to illustrate the extent of the problem.
North Anna Service wata, pumphouse settlement Summer Service water pumphouse settlement Shearon Harris Indequate moisture control in fill material Cherokee Inadequate field density control and soils tests Hatch Inadequate QC procedures and fill placement Vogtle Inadequate compaction, groundwater, and soil erosion controls South Texas Inadequate QC procedures and inspection documentation The above problems necessitated extensive remedial work; for example, removal of large quantities of fill material, underpinning structures, surcharging foundation materials, project delays, extensive reanalysis, and, in some cases technical specification requircments pertaining to settlement monitoring during plant operation.
The causes of insufficient compaction were investigated by NRC, licensees / con-struction permit holders, contractors and architect-engineering firms.
Based on these investigations, the various contributing causes were found to include the following:
1.
Soil selection, fill, and compaction activities were not accomplished under the direction of a qualified geotechnical engineer.

lEC 81-08 May 29, 1981 Page 2 of 3 2.
Compaction equipment was not qualified to achieve the required compaction using the material specified, lift thickness, moisture control, equipment speed, or number of equipment passes.
3.
Procedures for control of soil testing were not adequate to assure correct soil identification, selection of laboratory standards, and control of field density tests.
4.
Relative density and percent compaction test results fell outside the theoretical limits, indicating an unrealistic comparison of laboratory and field density tests.
5.
Soils inspections did not verify controls specified in construction specifications.
6.
Quality assurance audits did not identify the procedural inadequacies or the cause of repetitive nonconforming conditions.
7.
Design requirements were not properly translated into construction speciff-cations.
8.
Design change notices were not issued to reflect changes of construction specification requirements.
9.
Settlement calculations based on actual design bases (i.e., load intensity, index of soil compressibility, and type of foundation) were not perfor ed.
Recommended Action for Construction Permit Holders:
1.
For those facilities with ongoing soils work activities, verify that quality assurance and quality control measures including procacures, test results, inspection personnel and audits are implemented to assure that the causes identified above do not exist for the soils work in progress or planned.
2.
For those facilities with completed soils work activities that have a settlement monitoring program in effect, verify that the measured settle-ment values are within the projected values.
In the event the measured i
settlement values exceed projected values, it is recommended that an j
investigation to determine the cause be initiated.
In those cases, an evaluation which includes soil borings may be in order.
j l
3.
For those facilities with completed soils work activities that do not have an ongoing settlement monitoring program, verify that the quality assurance and quality control measures described in item 1 above were l
in effect during construction.
