/7 i y/ Abstract of Examinations .

This report contains a summary of the examination and test results for the inservice inspection (ISI) conducted at the Northeast Nuclear Energy Company Millstone Unit 3 Nuclear Power Station during the sixth refueling outage. This outage credits examinations for the third period of :

the first interval in addition to the first period of the second interval'. Included in this report are l the required ASME Section XI forms for the items examined (NIS-1) and repairs and replacements (NIS-2) that have been completed since the last Inservice Inspection Summary }

Report was submitted in September 1995. Reported herein are the examinations and tests j required by the ASME Section XI Code and the NRC through augmented requirements. l All examinations and tests were completed as delineated in the Millstone Unit 3 Inservice Inspection Program Plan. All examinations and tests completed meet the acceptance criteria stated in Millstone Unit 3 Inservice Inspection Program Plan.

Preservice weld examinations were performed on (53) new welds that were added due to j replacements within the Feedwater System and (6) new welds that were added due to l

replacements within the Reactor Coolant System. l Steam Generator tubing exams were performed in accordance with Section 4.4.5.0 of the Plant

,o Technical Specifications and ASME Section XI. .

! } !

Snubber visual examinations <md functional testing were performed in accordance with Section l 4.7.10 of the Plant Technical Specifications and ASME Section XI.

All required examination and test records and associated documentation generated during the performance of this inservice inspection are maintained at the plant for the service life of the plant.

' Under previous correspondence, NNECo informed the Commission ofits intent to extend the first ten year inspection interval for Millstone Unit 3 to October 23,1999. This extension is based on an extension period of 12 months, as allowed by Section XI (lWA 2430). and an additional extension of 30 months, as allowed by Section XI (IWA 2430), as a result of the extended shutdowns from July 1991 to February 1992, and from March 1996 to July 1998. Code Case N-535, approved for use at Millstone Unit 3, allows a successive interval to start prior to the end of the previous interval that was extended. Consistent with this, the stan date of the second I

inspection interval began on April 23,1999, allowing completion of the remaining examinations

, from the first inspection interval concurrent with the inspections to be performed during the

[mj v

second interval.

U 1.0 Introduction This inservice inspection summary report documents the inservice inspections conducted at Millstone Unit 3 during the sixth refueling outage from May 1,1999 through June 29,1999, when the generator was tied to the power grid. Preoutage examinations began on April 22,1999.

This report also includes the repairs and replacements performed and Gnalized during the period from the last summary report of September 1995 to June 24,1999. These examinations and tests were performed in accordance with the Millstone Unit 3 Inservice Inspection Program Plan.

Welds components, and their supports were examined in accordance with the requirements of the Millstone Unit 3 Technical Specincation, Section 4.0.5 and the requirements of ASME Boiler and Pressure Vessel Code,Section XI,1983 Edition, Summer 1983 Addenda (First Interval) and 1989 Edition, no addenda (Second Interval) except where noted in the Millstone Unit 3 Inservice Inspection Program Plan.

Millstone Unit 3 started commercial operation on April 23,1986. With interval extensions as allowed by ASME Section XI, IWA 2430, the nrst 10 year inspection has been extended to October 23,1999. Therefore this sixth refueling outage is the last outage in the third period of the Orst interval. Additionally, Millstone Unit 3 has began its second interval on April 23,1999 as allowed by approved Code Case N-535, with this sixth refueling outage also performing examinations for the nrst period of the second interval in accordance with this code case.

o Also included in this summary report are augmented inservice inspections performed to meet additional NRC requirements.

Examination and test procedures were approved prior to the outage. Also, certification documents relative to personnel, equipment, and materials were reviewed and determined to meet the requirements of ASME Section XI.

Manual nondestructive and visual examinations and tests were performed by Northeast Nuclear Energy Company, Northeast Utilities Service Company, ABB/Amdata, Inc., Rust Utilities, and ITI Inc. examination personnel. Vessel nozzle inner radius ultrasonic examinations were performed by personnel from Southwest Research Institute, Inc.

The Inservice Inspection Program was reviewed by the Ilartford Steam Boiler Inspection and Insurance Company. They provided NNECO with the Authorized Nuclear Inservice Inspector for the 1999 refueling outage.

All required examination and test records and associated documentation generated during the performance of this inservice inspection are maintained at the plant for the service life of the plant in accordance with ASME Section XI, IWA-6000.

2.2 ' Augmented j Table 2-1 A (First Interval) and Table 2-2A (Second Interval) address the interval status for augmented examinations performed to meet NRC requirements. Included in the listing are the augmented examinations to protect against postulated piping failures within the break exclusion ;

area (B.E.A.), the reactor coolant pump flywheel examinations required by Regulatory Guide 1.14 (RG 1.14), and examination of the reactor head and reactor internals lift rigs as required by ,

the Safety Evaluation Report, Supplement 2, for Millstone Unit 3 (FSAR). Note that a recent I 1999 license amendment approved a change to the Millstone Unit 3 Technical Specifications for l the examination requirements of the reactor coolant pump flywheels from that stated in Regulatory Guide 1.14 to that as stated in the Safety Evaluation Report (SER) relating to WCAP-l

. (J - 14535, dated September 12,1996.

]

, Examination Procedures used during the Millstone 3 ISI. Included is a complete list of the '

procedures used for impk menting inservice inspections.

Ultrasonic Examination P'rocedures

)

With the exception of piping welds, Ultrasome exammations for inservice inspection were performed in accordance with the requirements of ASME Section XI.

Piping welds were examined using a procedure developed by NU under the provisions ofIWA 2240 of ASME XI. NU used ASME XI, Appendix VIII, as a guide to develop the procedure, including qualifying the procedure on flawed specimens. The procedure utilized 70 degree

. longitudinal mode for detection and sizing of service induced flaws. The procedure is applicable to carbon steel and austenetic stainless steel butt welds.

Mannetic Particle Examination Procedures l

Magnetic particle examinations were performed in accordance with Article 7, ASME Section V.

_ Liauid Penetrant Examination Procedures Liquid Penetrant examinations were performed in accordance with Article 6, ASME Section V.

.Vj.sual Examination Procedurg Visual examinations were performed in accordance with Subarticle IWA-2210 of ASME Section XI.

Pressure Test Procedures

' Pressure tests were performed in accordance with IWA-5000 of ASME Section XI.
