Information Notice No. NO 86-25:   TRACEABILITY AND MATERIAL CONTROL OF 
                                   MATERIAL AND EQUIPMENT, PARTICULARLY 
                                   FASTENERS 

Addressees: 

All nuclear power reactor facilities holding a construction permit (CP) or 
an operating license (OL) 

Purpose: 

This notice is provided to alert recipients of potentially significant 
problems identified during NRC Construction Appraisal Team (CAT) inspections
of licensee programs for the inspection of material and equipment, 
particularly fasteners, to prevent the use of incorrect or defective 
materials, parts and components It is expected that the recipients will 
review the information for applicability to their facilities and consider 
actions, if appropriate, to preclude similar problems from occurring at 
their facilities However, suggestions contained in this notice do not 
constitute NRC requirements; therefore, no specific action or written 
response is required 

Description of Circumstances: 

During NRC CAT inspections conducted since 1982, deficiencies in material 
traceability and control of fasteners were identified at 11 sites This 
raised questions regarding the adequacy of controls to prevent the use of 
incorrect or defective fastener materials A brief summary of findings for 
each site is attached See Attachment 1 

Discussion 

The deficiencies in material traceability and control of fasteners 
identified at 11 sites mentioned above were attributed to ineffective site 
inspection programs and vendor surveillance activities by the licensees 
Deficiencies were found in fasteners for large vendor-supplied mechanical 
and electrical equipment (eg, pump-motor assemblies mounted on skids) and 
in bolting for battery racks and electrical equipment cabinets at many 
sites These and other deficiencies are described in Attachment I 

Because fastener deficiencies, if uncorrected, could adversely affect 
operational safety and/or safety in case of seismic events, recipients of 
this notice should review the information presented to avoid similar 
deficiencies at their facilities

                                                             IN 86-25      
                                                             April 11, 1986

It is important that particular attention be given to licensee programs for 
ensuring the traceability of material and equipment and to prevent the use 
of incorrect or defective materials, parts and components It is important 
that the licensee be aware of 10 CFR 50, Appendix B, Criterion VIII -
Identification and Control of Materials, Parts and Components and applicable
codes and specifications and that measures have been established and 
implemented for identification and control of materials, parts and 
components and for traceability both to the approved design basis and to the 
source It is important that required identification of the item is 
maintained by heat number, part number, serial number, or other appropriate 
means, either on the item or on records traceable to the item as required, 
and that required markings are on the item 

The licensee has the responsibility to use qualified individuals to examine 
markings on material arid equipment and verify that the markings represent 
material and equipment as specified by the design drawings and 
specifications  In the case of fasteners, compliance with the applicable 
material specification (eg, ASTM or ASME material and grade) is verified 
by required markings on bolts and nuts and certified material test reports 
or certificates of conformance as required by the applicable procurement 
drawings and specifications and/or by the applicable codes and 
specifications In the case of vendor-supplied equipment assemblies 
containing fasteners, it is important to verify compliance with approved 
vendor drawings and specifications and other information such as materials 
used for equipment qualification tests and/or analyses It is important that
caution be exercised to ensure that the required markings on material and 
equipment, including fasteners, not only exist but that the markings 
indicate the correct material and grade as specified 

No specific action or written response is required by this information 
notice If you have any questions regarding this matter, please contact the 
Regional Administrator of the appropriate NRC Regional Office, or this 
office

                    SUMMARY OF DEFICIENCIES FOUND DURING
                    NRC CAT INSPECTIONS AT VARIOUS SITES

South Texas Project Units 1 and 2 

During the NRC CAT inspection conducted at the South Texas Project in 
October and November 1985, lack of traceability was found for fastener 
materials for certain vendor-supplied large mechanical equipment assemblies 
mounted on skids and for certain electrical equipment It also was found 
that engineering had deleted the requirement of the specified national 
standard for manufacturers marking of fasteners intended for electrical 
cable tray and conduit supports, which contributed to the resulting 
uncertainty of fastener control and traceability during and after 
installation For details refer to Construction Appraisal Team Inspection 
Report 50-498/85-21 and 50-499/85-19 

Byron Unit 2 Station 

During the NRC CAT inspection conducted at the Byron Unit 2 Station in 
August and September 1985, significant lack of traceability was found for 
fastener materials, including assembly and mounting bolts for large 
vendor-supplied pumps/motors; bolts for battery racks, electrical switchgear 
and other equipment; and bolts attaching heating, ventilation, and air 
conditioning (HVAC) duct sections For details refer to Construction 
Appraisal Team Inspection Report 50-455/85-27 

Clinton Power Station 

During the NRC CAT inspection conducted at the Clinton Power Station in May 
and June 1985, lack of traceability was found for some vendor-supplied 
fastener materials, including bolts for large pump-motor and skid-mounted 
pump-turbine assemblies, and mounting bolts for HVAC control cabinets For 
details refer to Construction Appraisal Team Inspection Report 50-461/85-30

Millstone Unit 3 

During the NRC CAT inspection conducted at the Millstone Unit 3 site in

Shearon Harris Unit 1 

During the NRC CAT inspection conducted at the Shearon Harris Unit 1 site in
October and November 1984, problems were identified regarding traceability 
of fastener materials, including large embedded anchor bolts and equipment 
mounting bolts and nuts It was noted that both the applicant and the NRC 
Region II had previously identified such deficiencies and corrective actions
were in progress by the applicant For details refer to Construction 
Appraisal Team Inspection Report 50-400/84-41 

River Bend Unit 1 

During the NRC CAT inspection conducted at the River Bend Unit 1 site in 
July and August 1984, deficiencies were found in material traceability and 
control of some safety-related fasteners, piping flange components, and 
environmental control of weld filler material storage ovens Also, work or 
rework of some flange joints was being accomplished without QC or 
engineering knowledge or concurrence, which also resulted in a loss of 
material control For details refer to Construction Appraisal Team 
Inspection Report 50-458/84-23 

Seabrook Station 

During the NRC CAT inspection conducted at the Seabrook Station in April and
May 1984, problems were identified regarding traceability of embedded anchor
