Concrete Expansion Anchor Bolts used in Pipe Supports During the inspection the inspector examined concrete expansion anchor bol ts. The licensee uses Hilti Kwik-Bolts exclusively.
It was observed that the anchor bolt stud standout varied from bolt to bolt. This is normal for Hilti Kwik-Bolts.
It is the nature of these bolts to move out of the hole until the wedges set and full torque can be achieved.
The licensee's anchor bolt installation procedure ITI-005 Rev.1C of 4-18-79 does not limit the amount of stud-pullout allowed other than a check that the nut has not bottomed out on the threaded portion of the stud. The amount of stud pullout directly affects the amount of stud embedment and therefore the ultimate holding strength of the ancho.
-2-The licensee had previously committed to submit the factor of safety analysis required by IE Bulletin 79-02 by January 1980. The inspector explained in the exit interview that the ultimate pullout strength used in the calculations of factors of safety would have to be compatible with the anchor bolt embedment depths allowed in the field installations.
This item will be inspected further in the review of the licensees re-sponse to IE Bulletin 79-02.

Safety Related Piping Welding - Weldino Wocedure Specifications and Quality Assurance Procedures The inspector reviewed pipe welding specifications and procedures for field welding of piping outside the reactor coolant pressure boundary to determine whether the instructions were established, qualified and controlled in accordance with the licensee's QA program and code require-ments. The following J. A. Jones Welding Procedures were reviewed:
(1) JAJ-WQ-1, Rev. 2, Welder Performance Qualification Procedure (2) JAJ-WP-P1, Rev. 3A, General Requirements for Welding Group P-1 Carbon Steel (3) JAJ-WP-P1-5, Rev. 1, Carbon Steel (GTAW)

Safety Related Piping - Unit 1 a.
Observation of Work and Work Activities The inspector examined safety related piping installation in the General Services Building.
Piping installation activities were examined for conformance to WPPSS contract specification number 9779-257. The piping activities observed were temporary pipe hanger installation and pipe rigging and handling.
The inspector examined the temporary supports used on an approx-imately 80 foot run of 3 inch stainless steel piping in the make-up and purification system (MUS 411236-1) and a run of 25 inch stainless steel pipe (MUS 411247-3). The 25" pipe was temporarily supported by the 3" pipe, causing deflection sufficient to lift the 3" pipe off its adjacent support by 5/8 inch.
It could not be determined at the time whether permanent deformation had occurred in the 3" pipe. There are no code or specification re-quirementt for temporary hangering other than the general require-ment that :onstruction shall be conducted in a manner so as to avoid damage to equipment.
No items of noncompliance or deviation were observed.
At the exit interview the licensee management committed to investigate the potential deformation of MVS 411236-1 and to assess the need for procedure requirements or guidelines for temporary hanging of pipe. This item will be inspected further on a future inspection.
(Item 50-460/79-14/01)
b.
Review of Quality Records
.
The inspector examined the material certification records, vendor manufacturing inspection and non destructive examination records, and receiving inspection reports for 2h" stainless steel valve MUS-V-118, 20" carbon steel pipe spool CCW 411027-1, and 2h" stain-less steel pipe spool MUS 411243-8 for conformance to specifica-tion 9779-257.
No items of noncompliance or deviations were ob-served.
Discussions with personnel responsible for the vendor records reviewed indicated that the licensee did not have a method to assure that all required radiographic film was received.
As explained to the inspector, the system assured film received was logged and record-ed but did not assure that all film required was in fact received.

-4-At the exit interview licensee management committed to investigate the apparent problem. This item will be inspected further on a future inspection.
(Item 50-460/79-14/02)
The inspector followed up the records review by examining the 20" pipe spool CCW 411027-1 installed in the seneral services building.
The spool, as provided by the vendor, has a 4" weldolet which is connected to a 4" branch line by a field weld.
The 4" weldolet to 20" pipe spool welded connection, appeared to have insufficient weld (by h" of throat dimension).
The specific size requirements for the weld were not available on site. At the exit interview licensee management committed to obtein the specific weld size requirements. This item is unresolved and will be inspected further on a future inspection.
(Item 50-460/79-14/03).

Safety Related Piping - Observation of Welding Activities The inspector examined the welding of 25" stainless steel valve MUS-V-118 to pipe spool 411243-8, veld 004 on ISO 411243.
Attributes veri-fied correct were filler metal, base metal, weld machine polarity, weld-er qualification, purge gas, weld quality and technique, weld data sheet entries, weld identification and location, and interpass temperature.
flo items of noncompliance or deviations were noted.
The inspector observed that there was no information available at the worksite with which the welder or inspector could determine whether the valve body was type 304 or type 316 stainless steel.
Specification 9779-257 requires delta ferrite checks on production welds to type 316 stainless steel. JA Jones had not issued an implementing procedure
.
for delta ferrite checks on the premise that no type 316 valve had been ordered.
The inspector subsequently determined through the licensee's A/E personnel that the project would receive or had received a number of type 316 stainless steel valves originally ordered as " type 304 or better."
Licensee management at the exit interview committed to determine whether type 316 stainless steel valves had been received and installed and to implement procedures for ferrite control. This item is unresolved (50-460/79-14/04).
In examining the weld, it was determined that the weldedid not appear to have a clear understanding of the requirements for interpass temp-erature. The wel 'ers are not provided with temperature determining de-vices and although the QV inspectors do have devices, QV verification of interpass temperature is performed on a sample basis onl.-
-5-It was subsequently determined that welder training consisted basically of the reading of a one page general requirements information sheet, a discussion of the weld procedure and qualification on a bench test.
The information sheet does caution welders to adhere to interpass temp-erature requirements and interpass temperature is observed during qual-ification test welding, but welders are not given temperature indicating devices nor are they required to use them during qualification welding.
It was also determined that welders do not generally attend the periodic training sessions; these sessions are generally limited to the foreman level.
It was determined that welders are not instructed in piping system clean-liness requirements.
Several other aspects of welding important to quality work are covered very lightly in training.
At the exit interview licensee management committed to evaluate the adequacy of welder training. This item will be inspected further on a future inspection (50-460/79-14/05).
6.
Plant Tour The inspector walked through various areas of the plant to observe con-struction activities in progress, to inspect the general state of clean-liness and equipment protection. Protection of a number of Make-up Service (MUS) and Component Cooling Water (CCW) pumps appeared to the inspector to be marginal. Water, dirt, tools, debris, bags of grout were observed in and around the pumps.
Covers were not adequately protecting some pumps and the heaters for two MUS pump blower motors were missing.
This was discussed at the exit interview and at that time the inspector was informed that these items had been corrected.
_
This area will a further examined during a subsequent inspection (50460/7914/0 7.
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. Unresolved items disclosed during this inspection are discussed in Paragraphs 4b and 5 of this report.
