3 & 4 REPORT ON EXAMINATIONOF CONTAINMENT LINER PENETRATION WELDS (In Response to NRC IE Bulletin 80-08, April 7, 1980) 11EM 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 sleeve 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

Figures 1 and 2 show the penetration details used on the Turkey Point Plant which are within the scope of Bulletin 80-08.

Tables 1 and 2 indicate which containment penetrations are within the scope of this bulletin.

ITEM 2 If an affirmative answer is reached for Item 1, determine the following:

a.

Applicability of the ASME Code including year and addenda and/or Regulatory Guide 1.19.

b.

Type of nondestructive examinations performed during construction.

c.

Type of weld joint (including pipe material and size) and whether or not backing bars were used.

d.

Results of construction nondestructive examination, i.e., if repairs were required, this should be identified including extent of repairs and description of defects encountered during repair, if known.

RESPONSE

2(a)

The design, construction, inspection and testing of the penetrations in the scope of this bulletin were required by specifications to be in accordance with Subsection B of Section III (Nuclear Vessels) of the ASME Boiler and Pressure Vessel Code (1965, with Summer 1966 Addenda).

There is no FSAR commitment to meet the requirements of Regulatory Guide 1.19.

2(b)

Tables 1 and 2 indicate the type of nondestructive examination performed during construction for penetration connections applicable to containment Units 3 and 4.

2(c) (i)'llweld joints in the scope of this bulletin are containment.

boundary butt welds (See Figures 1 and 2 for types of butt welds specified).

(ii) Use,of backing bars is indicated in Tables 1 and 2.

(iii)

Pipe material was specified as follows:

1)

Forging conforming to ASTM A-350 (Grade LF2), or 2)

Seamless pipe conforming to ASTM A-333, or 3)

Welded pipe conforming to ASTM A-155 (Grade

KC70, Class I), with the exception that steel plate was required to conform to ASTM A-516 (Grade 70),

firebox quality to ASTM A-300.

For (1)

(2) and (3), impact specimens were required to be of charpy V-notch type and to meet the requirements of ASME Code Section III, Paragraph N-1211(a) at a test temperature of 0 F.

(iv) Fittings were specified to conform to ASTM A-234, Grade

WPB, tested to ASTM A<<300, except that the impact specimens were required to be of the charpy V-notch type and to meet the requirements of Paragraph N-1211(a) of S'ection III of. the ASME Code at a test temperature of 0 F.

(v)

Casting materials were specified to meet the requirements of Paragraph N-1211(a) of Section III of the ASME Code.

(vi)

Pipe and reducer sizes for Units 3 and 4 are indicated in Tables 1 and 2, respectively.

2(d)

The results of construction nondestructive examinations are tabulated in Tables 1 and 2 for Units 3 and 4, respectively.

These tables include a qualitative description of the defects encountered, as determined from the radiographic test reports.

All welds in which defects were encountered during testing were

repaired, re-examined, and found to be acceptable.

Penetrations for which records could not be located have been noted in Tables 1 and 2.

The information noted above and listed in Tables 1

and 2 was obtained from a document search of files located at the Florida Power and Light Company Turkey Point Plant.

ITEN 3 For those facilities committed during construction 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

As noted in the response to Item 2(d), and as shown in Tables 1 and 2, radiographic testing results could not be located for Unit 3 penetrations 22, 32, 37, 57, 61, and 63, and for Unit 4 penetrations 57 and 61.

Radio-graph Report logs indicate that radiographic testing was performed for Unit 3 penetrations 22 and 63;

however, these test results could not be located.

For both Units 3 and 4, penetration 57 is a spare penetration.

Further investigation has shown that Unit 4 penetrations 57 and 61A are enclosed on the inside of'ontainment in a major concrete structure and as such are not used.

Unit 4 penetration number 61B is shown on engineering drawings as being renumbered as number 46 which was tested and found acceptable.

We believe that similar dispositions can be made for the Unit 3 penetrations for which records could not be found.

We intend to review these penetrations at the next Unit 3 shutdown of sufficient duration.

We will then submit an update on our response to the Bulletin.
