" Examination of Containment Liner Penetration Welda"

Dear Mr. Seyfrit:

This letter is written to provide thu information requested by the nubject i

o-bulletin.

'i-

~

Question No. 1 Determine if your facility contains the flued head design for penetration connections, or other designs with containment boundary butt weld (s) between the penetration sleuve and process piping as illustrated in Figure NE 1120-1, Winter 1975 Addenda to the 1974, and later editions of the ASME B&PV Code.

Response

Penetrations using flued head fittings are utilized at CNS as drywell penetrations for hot process lines.

A listing of the containme t butt weids in question are shown on Attachment 1.

Question No. Ia If an af firmative answer is reached for Item 1, determine the following:

Applicability of the ASME Code, including year and addenda and/or a.

Regulatory Guide 1.19.

Response

The applicable 1969 piping contract states that materials, design, fabri-cation, inspection, and testing of primary contairrment penetrations were in accordance with the ASME Code,Section III, Subsection B, and compatible with the design criteria for the primary containment vescels and process piping; and that closure welds (Containment Butt We.1ds) for which radio-graphy saa impracticaj wore examinad by either a magnetic particle or liquid penetrant method on ene root and final weld service in lieu of radiography.

- A review of the welding and NDE. tests performed on the subject welds revealed tho~folicwing:

Shop Welds -

The procedures approved in 1971 reference ASME Sections III and IX.

Shop Dye Penetrant Test -

The procedure approved in 1971 references ASME Section III 1968 edition and ASTM E165-65 1968 edition.

Shop Radio 7raph Procedure -

The procedure app: oved in 1971 references ASME Section III, ASTM Section VIII, ASTM E94.-62T and ASTM E142-64.

Field Welds -

The procedures ~ approved in 1971 reference ASME Section III paragraph N1342, and ASME Section IX.as modified by B31.7 and B31.1.

-Field Magnetic Particle Inspection -

The procedure references B31.7.

,e

.i Questidn"No.2b Type of nondestructive examinations performed during construction.

Response

The NDE 3 performed are shown on Attachment 1.

In general, the shop butt welds were 100% radiographed except for Weld "0" on penetrations X-21, X-23, and X-24 which were dye penetrant checked on the root and final passes in addition to the hydro test because radiography was not possible.

The field butt welds were magnetic particle checked for both the root pass and the. final pass.

None of the welds reviewed employed ultrasonics as a NDE test.

1 Question No. 2c Type of weld joi.nt (including pipe material and size) and whether or not backing bars were used.

Response

In general, the shop butt welds did not use backing rings; however, the field butt welds did use backing rings. These are summarized'.along with sleeve size and materials in Attachment 1.

Mr. Karl V. Ssyfrit July 8, 1980 Page 3

  • Question? Nos 2d*

Resul'cs of construction nondestructive examinations, i.e., if repairs were requita'd, 'dtis shoofd be ide'ntified ideluding' ex~ tent of r'epairs 'and 'de-s.cription of defects encountered during repair, if known.

~

gg,gg l

Results of all NDE tests performed showed satisf actory results. No repairs were required.

QuestionrNo. 3 For thosh fac.111 ties committed during ecustruction to perform volumetric examination of such penetrations through SAR commitments which have not performed radiography, justify not performing radiography or submit plans and schedules for performing radiographic examinations.

Response

.j 4

No specific commitment to perform radiography-vas made in the FSAR. Page

~

' Even though radiography was not. performed.. there'is a high. ' degree of. hssur-ance.that these utids are adequath due to:

(1)' the length.of service of.the welda, (2).the results of NDE testa performed indicating soundnest of the
