s Functional or Program Areas Inspected Details of functional or program areas inspected are documented in the following paragraphs.
1.
Observation of Mechanical Splice Work Activities and Review of Related Quality Records The RIII inspector observed in-process mechanical (Cadweld Type "T")
l splice work in the Containment Dry Well Slab at elevation 803'-3"
'
and reviewed specific cadweld quality documentation relating to this work as follows:
i a.
Two cadweld splice operators (Nos. 118, 460) were each observed to properly:
(1) flame dry the #11 reinforcing steel bar ends and cadweld sleeves to remove all moisture and/or burn away any other foreign matter.
(2) remove all loose mill scale, ust, etc., with a hand wire brush.
(3) set the gauge lines 12 inches from the end of each rein-forcing steel bar.
(4) position the cadweld sleeve, install packing material, and place all related fittings in preparation for the splice.
(5) remix the ferrous filler material.
(6) break off the riser after completion of the splice and reverify cadweld sleeve position.
b.
The Cadweld Operator Individual Performance Logs for operator nos. 118 and 460 were reviewed. Each operator's qualifications were verified to be current and in accordance with Baldwin Associates Procedure BAP 3.1.5 Revision 6.
c.
The temporary storage area for cadweld splicing materials was inspected.
It was noted that the temperature of the storage area _was being checked once daily by the responsible Baldwin Assoicates (BA) QC inspector to verify the required 40 to 140 temperature. This check did not include the use on a regular basis, of a calibrated thermometer.
In response to this concern, the licensee stated that the daily monitoring of the storage area will be upgraded to include the use of a calibrated thermo-meter. The inspector has no further questions about this matter.

d d.
The RIII inspector verified that the responsible Civil Superin-tendent was properly maintaining the cadweld traveler as required by BAP 3.1.5.
No items of noncompliance were identified.
2.
Observation of Protective Coatings Work Activities and Related Quality Records The RIII inspector observed the implementation of the Midway Indus-trial Contractors, Inc. (MIC) and BA receipt / inspection program for Service Level I coatings and reviewed quality documentation as follows:
a.
The LA QC Receiving Inspection Reports and accompanying Carboline QA Certification Records for Carboline 191 HB Part A (Batch Nos. 9L2342M and 9K1814M), Carboline 191 HB Part B (Batch Nos.
9M2573M and 9K1960M), 195 Surfacer Part A (Batch No. 8J1884M)
and 195 Surfacer Part B (Batch No. 8J2024M) were reviewed.
b.
The following MIC QC inspection equipment was inspected to verify current calibration verification.
Item Number Calibrated Surface Thermometer SN-8698 1/4/80 Sling Psychrometer SN-9060 1/4/80 Microtest Guage SN-9157 Verified before and after use Coating Thickness SRM-1362 Traceable to NBS Calibration Standards c.
The Service Level I protective coatings storage trailer was inspected. The recording thermometer, used to verify proper storage temperatures, was located approximately five feet from the trailer floor. The RIII inspector expressed concern if the thermometer, in it's present location, was recording tempera-tures represantative of the coldest temperatures in the trailer.
(i.e. at floor level).
In response, the licensee stated that the recording thermometer would be relocated in a location more representative of the coldest temperature and/or that the coating material would be stored on pallets, thereby allowing warm air to circulate under the bottom coating containers during storage. The inspector has no further questions on this matter at this. time.

d.
Through discussions with various protective coatings QC and production personnel, it was noted that the base reading on uncoated steel surfaces was not established at the Clinton site for the use of the Microtest magnetic dry film thickness gauge.
Application of this base reading assures the inspector that the mil thickness he reads is representative of the true coating thickness applied above the peaks of the surface profile. This item is considered unresolved and will be reviewed during a subsequent inspection.
(461/80-01-01)
No items of noncompliance were identified.
3.
Safety Related Concrete Curing Activities The RIII inspector confirmed that placement nos. D6-R-4-2, 4-3, and FS-3-1 were being cured in accordance with ACI 301-72, Chapter 12 as required by S&L Specification K-2944 Additionally, cold weather protection was verified to be adequate to maintain both placements above the temperatures specified in ACI 306-66, Table 1.4.1, Line 7, for three days after placement as required by S&L Specification K-2944.
No items of noncompliance were identified.
Unresolved Items Unresolved items are matters about which more information is ree,uired in order to ascertain whether they are acceptable items, items of noncompli-ance, or deviations. The unresolved item disclosed during the inspection is discussed in Paragraph 2.d.
Exit Interview The inspectors met with site staff representatives (denoted in the persons contacted paragraph) at the conclusion of the inspection on January 10, 1980.
The inspectors summarized the scope and findings of the inspection. The
. licensee acknowledged the findings.
