EXAMINATION OF CONTAINii1ENT LINERPENETRATION MELDS

The subject 18E Bulletin requested data on Non Destructive Examination (NDE)performed on full penetration butt welds made between containment penetrationassemblies and the penetration sleeve, and penetration assembly flued head toouter sleeve welds. Figures 1 and 2, attached, illustrate the types ofpenetration assemblies utilitized at St. Lucie Unit ¹l. Note that containmentboundary butt welds have been identified on Figures 1 and 2, and consist offield welds made during construction and shop welds made by the penetrationassembly fabricator, Tube Turns Division of Chemetron Corporation.

The date of issue of the Purchase Order with Tube Turns was June 30, 1971.Fabrication of the penetration assemblies and shop welding was done inaccordance with ASNE Section III, 1971 Edition. The design specification forthe assemblies and manufacturers and fabrication drawi ngs both requiredRadiography (RT) as the method for NDE in accordance with the code. TubeTurns has been contacted and has assured that no exception was taken on anyassembly to the RT examination requirements (see Tube Turns letter dated6/2/80, attached).

The following and Table 1, attached, are our responses to the action itemsenumerated in'he subject Bulletin and are directed to the field welds only:1. Penetration assemblies affected are as listed in Table 1 and illustrated

in Figures 1 and 2.

2a. Although issue of the Construction Permit allowed the use of ANSI B31.1,St. Lucie Unit ¹1 committed to compliance with ANSI B31.7, 1968 Editionwith 1969 Winter Addenda for construction. Acceptance standards for non-destructive examination (NDE) were in accordance with the draft ASHESection III, 1968 Edition with 1969 Winter, Addenda.

2b. Type of NDE performed as per attached Table l.2c. Type of weld joints and joint details as per attached Table l.2d. Results of NDE as per attached Table l.3. Radiographic examination of full penetration circumferential butt welds in

penetration assemblies which are part of the containment pressure boundaryis required per, code. However, when the joint detail does not permitradiographic examination such as on complex-designed mechanicalpenetrations, due to access limitations and/or geometric unsharpnessfactors, ultrasonic examination plus liquid penetrant or magneticparticulate examination may be used in lieu of radiography (reference ASNESection III, NE 5211.1). This option was exercised on approximately 50$

of the weld joints listed in Table 1, since ultrasonic examination is, bycode, an acceptable alternate to radiography for volumetric examination ofopen root type butt welds.

A major concern in using ultrasonic exami nation for open root butt welds isthat if a backing ring is used during welding, it may distort the results ofthe examination in the root area. The welds listed on the attached Table andall shop welding were done without the use of backing rings or bars except inthe case of penetrations P-40, P-64, and P-33. As part of the final repairwelds to these penetrations in order to preclude additional weld-inducedresidual stresses, backing strips were used for sections of the welds and thewelds were accepted by ultrasonic examination. The welds in Penetrations P-40

. and P-64 were examined by radiographic exami nation during a recent plantoutage and were accepted.

Penetration P-33 is for the containment sump suction piping and is one ofthree Type IV penetration assemblies (see Figure 1). The weld in question islocated in the reactor auxiliary building pipe tunnel and would be extremelydifficult to RT without disassembling the penetration. Therefore it isimpractical to RT P-33. There is a high level of confidence in the integrityof the weld, however, based on the results of RT on P-40 and P-64. The threepenetrations were all assembled and inspected in accordance with the samecodes and procedures during plant construction. For these reasons, we areconvinced of the integrity of the weld and no radiographic examination hasbeen scheduled for P-33.
