IfN R11 Rpt. Nos. 50-416/78-11 and 50-417/78-11 I-2 dlL s-F.xamination of licensee records and discussions with responsible engineers and testing personnel indicated testing and work related equipment has been reinspected and recalibrated, testing personnel were knowledgeable and certified in areas of responsibility and that work activities are continuously inspected by QC personnel and periodically observed by QA personnel.
The inspector has no further questions regarding this item.
3.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of
noncompliance, or deviations.
Two unresolved items diclosed during l
the inspection are discussed in paragraph 5.
4.
Independent Inspection The inspector examined the following areas:
General inspectice of the site and engning vork activities, a.
b.
Installation of cinch anchors, and controls for cutting of reinforcing steel in the Unit 1 Auxiliary building, Work activities at the soils and concret laboratory.
c.
Observation of work activities at the concrete laboratory disclosed the following noncompliance:
Specification number 964-C-191.0 and referenced ASTM Standard C 31-69 require that concrete test cylinders made in the field be stored under conditions that maintain the temperature in the range of 60 to 80 degrees Fahrenheit.
Contrary to the above requirement, during the inspectica test cylinder sets 2650 A-D, 2651 A-D, 2652 A-D, 2653 A-D and 2654 were on the floor of the concrete lab exposed to full sun and an ambient temperature of 99 degrees Fahrenheit. The situation occurred as a result of the roof and sides at the laboratory recently having been removed to repair damage caused by a tornado on April 17, 1978.
When the inspector pointed out the nonconforming curing condition, the licensee issued NCR number 2733 and took ic. mediate steps to correct the matter.
Failure to perform test activities as required by documented I
instructions is contrary to Criterion V of Appendix B to 10 CFR 50 and was identified to the licensee as Inf raction 417/78-11-01.

R11 Rpt. Nos. 50-416/78-11 and 50-417/78-11 I-4 Examination of the above documents and discussions with responsible MP&L and Bechtel personnel disclosed the following unresolved items:
Acceptance Criteria on Air Temperature and Slump at Batch Plant a.
Acceptance criteria for in process tests on air temperature and slump performed at the batch plant on punped concrete do not appear to be clearly defined in the specifications. Discussions with QC and QA personnel indicated that the specifications are not being interpreted uniformly. This was identified to the licensee as Unresolved Item 417/78-11-02.
I b.
Frequency of In process Correlation Testing, Pump.ed Concrete Examination of records indicated the location and f requency of sampling for testing of air, temperature and slump were not in accord with the PSAR. Discussions with MP&L and Bechtel personnel indicated changes in the location and frequency of sampling were based on correlation tests, engineering evaluation and changes in (
the cur rent ANSI Standard N45.2.5 - 1978. They indicated their specification in ese and FS?R currently at NRR, which was scheduled for docketing en June 30, 1976, reflected their 1, resent mode of testing.
The licensee indicated his mode of operation, change, and basis for changes that have occurred to date are as follows:
(1) PSAR, December 1974 - August 1977 Sample and test at point of placement every 50 yards for slump and temperature and every 100 yards for air and test cylinders.
(2) FSAR, August 1977 i February 1978 (Change reflected in FSAR based on correlat a testing and engineering evaluation during operations 1. ween December 74 - August 77)
Sample at batch plant every 50 yards for slump and temperature and every 100 yards for air and cylinders. Make correlation tests every 200 yards at point of placement for air, temperature and slump; working limits at point of placement.
(3)
Specification 9645-C-191.0, Revision 13, February 1978 to j
July 7, 1978 (change based on engineering evaluation of operations to date and ANSI standard N45.2.5 - 1978).

correlation tests for air, temperature and slump every 500 yards at point of placement; working limits at point of placement.
Subsequent examination of the FSAR and ANSI Standard N45.2.5 -
1978 at Region 11 indicated the licensee's current mode of in-process testing appeared to be a deviation from the FSAR and ANSI Standard N45.2.5-19 78.
The licensee was notified on July 5, 1978 of NRC's concern regarding the mode of in process testing.
On July 7, 1978, per l
telephone conversation with Region II IE, the licensee agreed to
return to the mode of operation stated in the FSAR and as discussed in paragraph Sb(2) (appears to agree with ANSI N45.2.5-1978).
Following several phone conversations with NRR, Headquarters 1E, f
and responsible personnel at MP&L and Bechtel, the licensee was noti fied per t elephone on July IS,1978 t hat the matt er rega rding frequency of in process correlation testing would be an unresolved item pending RII IE review of the licensee's justification for deviating from the PSAR, FSAR, and ANSI Standard N45.2.5, 1978.
This is unresolved item 417/78-11-03.
