1.0 INTRODUCTION
Recently, the United States Nuclear Regulatory Commission (NRC) identified a series of generic issues which could potentially cause the seismic analysis of safety-related piping systems to yield inaccurate results.
One of these issues involves the correlation of the as-built piping configuration to the information used for the seismic anal-ysis of the piping systems.
Due to this concern, the NRC published IE Bulletin 79-14 (Reference 1), and the subsequent supplement to the Bulletin (Reference 5) which require that an inspection be conducted to verify that the input information for the seismic analysis of safety-related piping systems reflect as-built configurations.
Further, the Bulletin requires that, where deviations from seismic analysis input information are found, the licensee must consider the need tc reevaluate the seismic analyses to the as-built configuration or modify the hardware.
This report describes the inspection to be conducted on the Seismic Category I and safety-relateu piping systems at Northern States Power Company's Monticello Nuclear Generating Plant in response to IE Bulletin 79-14.
The inspection will compare the as-built configuration to the information which is required for the seismic analysis of 014179 nutech 1-1
NSP-37-005 the piping, e.g.,
piping rize and wall thickness, piping configuration geometry, valve locations, valve operator orientations, and support locations, and type of support.
The inspection covers the Seismic Category I and safety-related piping systems defined in Section 2.0.
Resolution of identified discrepancies will consist of the following three approaches as allowed by the one Bulletin:
1.
An engineering evaluation of the discrepancies to show the original analyses are still valid.
2.
A reanalysis of the as-built configuration, or 3.
Modification of hardware to comply with the input information for the seismic analysis.
The final resolution of all discrepancies will be documented in a final report which will confirm that the as-built piping configuration is in conformance with the require-ments of the Final Safety Analysis Report (Reference 2) for the plant.

NSP-37-005 2.0 APPLICABLE SYSTEMS AND REPORTING SCHEDULE NUTECH, with support from Northern States Power Company (NSP) and Bechtel Power Corporation (Bechtel), will conduct an inspection of the safety-related piping systems for the Monticello Nuclear Generating Plant.
The purpose of the inspection is to compare the as-built piping configurations to the information used as input to the piping seismic analyses.
Any discrepancies found during the inspection will be resolved as described in Section 4.0.
All work associated with the inspection will be in accordance with the requirements of IE Bulletin 79-14.
The piping systems to be inspected consist of all Seismic Category I systems which were dynamically analyzed by computer and all safety-related systems with outside diameters of 2 -inches or greater.
The list of the Seismic Category I and safety-related systems to be considered is given in Table 2.1 along with the applicable line segments and isometric drawing numbers as available at this point in time.
The inspection of the piping systems will be conducted in two phases.
The Phase 1 inspection will cover, as a minimum, one system in each set of redundang normally accessible systems and all non-redundant accessible systems where accessible systems are defined to be those systems located e a4 o,,k k.

3.0 DESCRIPTION
OF INSPECTION The actual inspection consists of three separate tasks.
(1) an as-built inspection of the piping systems at the plant site, (2) a compilation of the input data for the piping analyses, and (3) a correlation of the results from Tasks 1 and 2 above to show conformance/nonconfor-mance between the installed and analyzed piping.
The details associated with each task are described in the following sections.
3.1 As-Built Inspection NUTECH, wi'h support from NSP, is responsible for completing the as-buitt inspection of the piping systems.
The inspection will consist of measuring and recording physical dimensions and hardware information in enough detail to allow a complete comparison with the analysis input data.
The actual information to be gathered at the site and the methods used to obtain the data are provided in Table 3.1.
Prior to the inspection, data books will be prepared by NUTECH for each system.
A sample data book is provided in Appendix A.
As can be seen, this book specifies the dimensions and other inforn.ation to be gathered at the site.
The information contained in the data books is DL* : n 1 3
.v a nutech 31
NSp-37-005 based on the drawings listed in Table 2.1.
Additional sources of information relating to the piping systems and specific data for each source are provided in Appendix B.
The data book provides a location for signatures of the inspection team members and for the approval of the NUTECH site Proj ect Engineer, all of which are required to complete the inspection.
The work copies of the data books will be maintained at the site until completion of the inspection.
The data recorded in the work copies will be transcribed to the NUTECH office copy which will be on file at the NUTECH office in San Jose, California, and will be the basis for the work described in Section 3.3.
3.2 Compilation of Analysis Input Data Bechtel is responsible for compilation of the input data for the analysis of the piping systems.
This work effort will consist of organizing dimensions and hardware infor-mation used in the piping stress analysis (see Table 3.1) in a form easily comparable to the informr. tion obtained from the as-built inspection and recorded in the data books.
All information will be signed off and transmitted to NUTECH in accordance with approved quality assurance programs.
3111.50 nutech 3-2
NSP-37-005 Revision 1 3.3 Correlation of As-Built and Analytical Data NUTECH is responsible for correlating the results of the inspections described in Sections 3.1 and 3.2, and identifying any nonconformance which is determined.
The as-built data and the analytical data will be in conformance so long as the differences remain within the tolerances specified in Table 3.2.
These tolerances, while allowing for some deviation, are sufficiently restrictive to ensure system operability under specified earthquake loadings.
Any measurement which exceeds the specified tolerance limit will be identified as a nonconformance and will be evaluated in accordance with the requirements of Section 4.0.
In addition, any abnormal conditions which are found at the time of the site inspection will be reported immediately to NSP via the nonconformance report form provided on Page 4-4 These would include conditions such as nonfunctioning supports, e.g., damaged supports or improperly installed supports, and obvious discrepancies in piping configuration.

NSP-37-005 Revision 1 4.0 REPORTING AND RESOLUTION OF NONCONFORMANCES NUTECH is responsible for resolution of all nonconformances subject to NSP review and approval.
In resolving each identified nonconformance, the following approach is to be taken:
- 1. An engineering evaluation will be made of the nonconformance to determine if the nonconformance might impair the operability of the system.
This evaluation will be performed at two levels.
The first level consists of applying engineering judgment to the nonconformance to obtain an immediate, i.e., within two (2) days, evaluation of the impact of the nonconformance on system operability.
The second-level evaluation will be made within thirty (30) days and consists of an analytical evaluation of the discrepancy.
This evaluation may require the same degree of sophistication as was utilized in the original seismic analyses or a less rigorous analysis technique may be adequate for resolution.
If it is determined at either level of the evaluation that system operability is impaired, a nonconformance report form, as shown on Page 4-4, must be completed and reported to NSP immediately to ensure timely reporting to the NRC in accordance with technical specification requirements.
SJnm nutech 4_1 I
NSP-37-005 Revision 1
- 2. An additional evaluation of the nonconformance will be made to determine if the analyses described in the FSAR are no longer conservative.
Where it is determined that the original analyses are conservative, no further action is required.
However, if the original analyses are found to be unconservative, then additional action is necessary and will consist of either of the following:
a.
Reanalysis of the piping system to as-built conditions will be done in cases where the nonconformances do not warrant hardware modifications.
The piping system will be reanalyzed to the as-built conditions and the design requirements given in the piping system design specification.
A revised stress report and revised drawings, reflecting the as-built conditions, will be issued to document the acceptability of the nonconformance.
b.
Installation or modification of hardware to comply with the original stress analysis will be done in cases where this approach is deemed appropriate.
Where modifications are made to the hardware, revised drawings and stress reports will be issued to document the changes.

APPENDIX B NSP-37-005 SUPPORTING DOCUMENTATION The data utilized for the inspection plan is contained in various documents developed by Bechtel, GE, and National Valve and Manufac-turing Company (NAVCO).
A general description of the data provided in each type of document is given in the following pages.
Specific document information, i.e.,
document number, revision, date of revision, and title, is listed in Tables B.1 through B.3 for the Bechtel, NAVCO, and GE supplied items, respectively.
BECHTEL DOCUMENTS 1.
PIPING AND INSTRUMENTATION DIAGRAMS (P6ID's)
A schematic representation of the piping, process control and instrumentation for a specific mechanical system and shows the functional relationship among the various components.
A PSID serves as the primary record of system requirements for piping, duct work, valves, dampers, instruments and related equipment.
The following items are schematically represented on PSID's.
a.
Mechanical equipment b.
All valves and dampers, including vent and drain valves, except instrument valves and instrument take off root valves.
c.
Local and remote instruments in sufficient detail to delineate the function (s) of the instrumentation and its interface with the process.

PIPING CLASS SHEETS The piping class sheets define the characteristics of unique material classes within the piping system.
The information con-tained on the piping class sheets is:
a.
Class - Classes are designated by a two letter code.
The first letter designates the primary valve and flange rating; and the second letter the type of material.
b.
Pipe - the pipe material specification is called out for all applicable sizes of pipe for the applicable class sheet.
Wall thickness for all sizes are shown.
c.
Fittings - The fitting material specification is specified, along with the type of acceptable weld connection.
d.
Flanges - The flange material specification is called out and also the type of flange to pipe joint and style of flange face.
c.
Gaskets - For all applicable sizes, the recommended gasket material is specified.
f.
Bolting - The bolt and ssociated nut material are specified.
g.
Valves - The valve rating, type of end connection, and applicable valve type are specified.

Joints - The applicable drawing showing the weld end preparation and weld end transition is referenced.
i.
Branch connection - The drawing of acceptable branch connections is included.
5.
INSULATION CLASSIFICATION AND THICKNESS This is a tabulation of the insulation thickness versus pipe size for different types of insulation class.
6.
STRESS IS0 METRICS These were sketches prepared by Bechtel or subcontractor to stress analyze the piping system.
They were based on the area drawings.
NAVC0 DOCUMENTS 1.
FABRICATION ISOMETRICS These are isometric presentations of the piping system in the configuration at the plant.
These isometrics were primarily prepared by NAVC0 (pipe fabricator at Monticello) and were used for fabrication and construc tion.
The isometrics were prepared from the Bechtel area drawinrs described above.
GE DOCUMENTS 1.
PIPING AND PIPING SUPPORT DRANINGS These are drawings which provide the piping data utilized in the analysis of the Reactor Recirculation System.
The information consists of the piping configuration, pipe size, and pipe fittings.
