NRC Independent Measurements There was an independent verification inspection performed at the Byron Station, Unit 2, using the NRC NDE van and contractor technicians under NRC direction.
Construction activities and materials were sampled through nondestructive examinations (NDE) as a supplement to the existing inspection efforts.
The onsite inspection began on October 28, 1985, and was completed on November 7, 1985. The NRC (Region I) requested documentation packages for each of the welds selected to be prepared by the licensee.
The NRC
,
reviewed the licensee's documentation packages in Region I prior to site inspection and updated the NRC's procedures to be consistent with the licensee's procedures. The licensee prepared packages containiag the following information for each of the welds selected:
~ ~
Inspection Report
.
Material Certifications for base materials
Weld Wire Certifications
Piping drawings, Isometric of weld locations
NDE Reports on all NDE performed
.
NDE Procedures for RT, PT, MT, and VT
Weld Procedures
Bolt Torquing Procedures (Structural and Pipe Hangers)
Piping and Installation Procedure (only section that specifies
code and addenda)
The NDE van team performed the following examinations and inspections,
as appropriate:
Radiography - Pipe butt and socket welds, appropriate pressure boundary
components.
Ultrasonics - Flaw detection and material thickness measurements, as
appropriate, piping, welds, structural components, vessels,
heat exchangers, bolting, and other equipment.
Liquid Penetrant - Piping system components and structural elements.
Magnetic Particle - Piping system components and structural elements.
Hardness Testing - All of the previously listed components.
Delta Ferrite Indications (Severn Gage) - Stainless steel welds.
Alloy Analysis - Selected metallic components will have confirmatory
chemical analysis performed.
Visual Examination - Weld quality, cot. figuration verification of piping
and structural systems.
'
Quality Records Review - Welding documentation, materials and personnel
certifications, NDE records to incit.de radiographs.
The results of the above inspections are documented in NRC Inspection
Report No. 50-455/85031.
No violations or deviations were identified by the NRC Region III
inspector.

NDE Personnel Certifications, Observations of Work Activities, Data
Reports and Audits
The NRC inspector reviewed selected NDE personnel certifications in
accordance with SNT-TC-1A.
The certifications of Level IIs and IIIs
that were certified by EPRI for IGSCC were also reviewed.
The NRC inspector also observed the work and had discussions
with personnel during review of the following activities.
These
observations included calibrations, performance of t,he, examinations,
and review of selected documentation.
Ultrasonic examination of Weld No. PN-02, pressurizer nozzle,
performed by EBASCO and ultrasonic automatic examination of
Weld No. WR-34, reactor vessel, performed by Rockwell.
Eddy current examinations of steam generator (SG) tubes in
SG No. ZRCOLBA (SG No. 1) and SG No. ZRC01BD (SG No. 4),
performed by Conam.
Magnetic particle examinations of reactor vessel studs,
performed by EBASCO.
Audits of PSI, performed by EBASCO and surveillances, performed
by Ceco.

Containment (Structural Steel Welding) - Work Activities and Review
of Quality Records
The NRC inspector observed the following field welding activities
associated with steel containment structures and steel supports within
containment acd determined that the requirements of applicable
specifications, standards, work performance, and inspection procedures
were me6
,
Beam No. 63301 was being prepared for a side coverplate.
Observed
that the in plate Angle stiffeners were notched to receive a backup
bar for the coverplate.
Beam No. 74118 was being prepared for a side coverplate.
Observed
fit up of a backup bar to the bottom of the top flange.
.
Beams Nos. 15811 and 22201.
Visually examined completed beams in
place including side coverplates.
Supports No. 2SIO4009 and 2RY06012.
Observed welding and visually
examined welding on the supports that were being increased in
structural size.
Support No. 2RC93A012.
Observed fit up and welding on a new
installation.
Support Nos. 2RY0615, 2RY06012, 2RY06103, and 2RYO6104.
Observed
welding and visually examined welding on a new installation.
Component support process sheets, weld records, bill of materials,
drawings, weld material stores requisitions and ECN's were included as
part of this review.
The NRC inspector also toured the welding material issuing room and
observed the storage of materials, identification, segregation and
cleanliness for conformance with the requirements of applicable
specifications and procedures.
A#ditionally, the NRC inspector determined that the records of the
following welds were in conformance with established procedures and
reflected work accomplishment consistent with applicable requirements:
