-2-An examination was made of the following documents concerning the installation and inspection of concrete expansion anchors for pipe supports, HVAC and electrical equipment:
DPC QA Procedures M-15, M-18, M-41, M-52

Draft Bahnson/Envirotech procedure for inspection of expansion anchors for HVAC work.
Inspection requirements were discussed with QC inspectors and QA en-gineers involved in the various activities utilizing concrete expansion anchors. The following two areas that require further procedural clarification were identified. At present, the above documents contain no acceptance criteria for gaps between base plates and walls caused by irregularities in the concrete surfaces.
A draft change to specifica-tion CNS-Il96.02-00-0000 to address gaps is under review by site QA personnel and was examined by the inspector.
Secondly, the need for sufficient load testing or torque checking of installed expansion anchors was discussed with the licensee. This inspection is not con-sistently addressed ty the existing procedures governing anchor in-stallation for the various safety-related applications; HVAC, piping and electrical supporte. Clarification of these two areas has been identified as Inspector Follow-Up Item 413/79-03-01.
QC inspection of anchor bolt installations for pipe and HVAC supports has not yet begun.
No deviations or items of noncompliance were identified.

Safety-Related Structures (Structural Steel Supports)-
Observation of Work and Work Activities (Unit 1)_
The containment spray heat exchanger foundation was examined for com-pliance with configuration, location, dimensional and material require-ments of DPC drawings CN-1220-43, Revision 3, and CN-1224-2, Revision 13.
Additional acceptance criteria for this item are contained in PSAR Sections 3.8 and 17, QA Procedures M-18 and M-21 and Construction Procedures 22 and 23.
Grouting of floor anchors and installation inspection had not yet been accomplished on this structure.
No deviations or items of noncompliance were identifie *

Safety-Related Components-Observation of Work and Work Activities (Unit 1)
Containment spray pump casings 1A and IB were examined for proper
-
installation, in-place storage and protection. These casings had been set on their support columns, but the pump supports had not been com-pleted and pump internals had not been installed.
Installation and storage and maintenance requirements are contained in the following documents:

-
QA Procedures P-3, M-5, M-9, M-10, M-21 and M-30 Installation and inspection requirements were discussed with the re-sponsible construction engineer and QA personnel.
No deviations or items of noncompliance were identified.

Safety-Related Components-Review of Quality Records (Unit 1)
The inspector examined quality records for containment spray pump casings IA and IB and the four steam generators.
The following containment spray pump records were examined for com-pliance with QA Procedure P-1 and the documents listed in paragraph 7 above:
Form P-3A, Serial M-112, " Equipment Special Storage and Main-
-
tenance Inspection"
-
Form P-3B, " Storage and Maintenance Requirement Change Notice" Form M-9B, " Equipment Release Document for the Installation of
-
Rotating and Non-Rotating Equipment" Form 9-D, " Process Control Sheet for Installation of Rotating and
-
Non-Rotating Equipment"
,
.
J-4-Form M-10A's, " Process Control and Inspection of Torque to Bolts
-
and Studs", for pump hold down bolts ar' foundation anchor bolts Form P-1A, " Receiving Inspection Information Report"

ASME Code Data Reports
-
-
Form H-30A, "NDE Inspection Record" for support column top plate UT.
Three plates had not yet been UT'd after fabrication.
Form M-21A, " Field Weld Check-Off-List (Structural Steel)" for support column assembly CSI-I Form M-5A, " Structural Grouting Inspections"
-
During this review, it was noted that no inspections were required by the M-9 forms to verify that the pump support assemblies (col imns and lateral restraints) met drawing requirements as to location, size, configuration, material size and type, etc.
These inspections are not specified in the procedures governing the site fabrication of these supports either. Documents covering installation of RHR pumps with identical supports also lacked this inspection requirement. Most steel structures and supports are installed per QA Procedure M-18, "Inspec-tion of Structural Steel Erection", which requires QC inspection for location, size, orientation, material size and type, etc. The require-ments of M-18 had not been invoked for these pump supports.
Licensee personnel are evaluating the need for procedural changes.
Because fabrication, installation and inspection of these pump supports are not complete, this question concerning inspection requirements is identi-fied as Inspector Follow-Up Item 413/79-03-02.
The following steam generator quality records were examined:
