STATEMENT OF APPLICABILITY This program outlines details for planning and performing the first interval inservice inspection (ISI) nondestructive examinations (NDEs) for Units 1 and 3 of Browns Ferry Nuclear Plant (BFN) Code Class 1,

2 and 3 equivalent components.

The program is organized to fulfillISI requirements of SSP-6.10, ASME Section XI Inservice Inspection Program; the 1974 Edition, Summer 1975 Addenda of Section XI of the ASME Boiler and Pressure Vessel Code; and applicable portions of the BFN Techn'ical Specification Surveillance Requirement 4.6.G.

In accordance with 10 CFR Part 50, 50.55a(g),

this program meets the ISI requirements to the extent practical.

Specifics concerning performance of NDE are not a part of this program but are included in NDE procedure

(}MP 110.5.

ASME Section XI Boundary Drawings and ISI Drawings listed in Appendix B

are issued and controlled through BFN Document Control and Records Management (DCRM) and are prepared/revised by M/N Engineering.

2.0 PURPOSE The ISI Program is employed to obtain data which can be used to determine if a component flaw is individual or of a generic nature, which would signal for examination of like components in the system.

Personnel responsible for performance of the examinations should familiarize themselves with the requirements of this program prior to performing the examinations.

The examinations required by this program shall establish acceptance for continued use of components during operation.

The ISI Program reflects the built-in limitations caused by original plant design,

geometry, construction component materials, and the current technology or state-of-the-art nondestructive testing.

The ISI Program shall also detail components to be examined, examination methods

selected, and schedule charts for planning examinations.

3.0 INSPECTION INTERVALS AND INSPECTION CYCLES The inservice examinations required by ASME Section XI shall be performed during each inspection interval.

'The inspection intervals represent calendar years after the unit has been placed into commercial service.

The first 10-year interval may be extended by as much as one year to permit inspections to be concurrent with plant outages (if the interval is extended, the following interval shall be decreased by an equivalent amount).

If the unit is out of service continuously for one year or more, the inspection interval may be extended for an equivalent period.

The inspection interval shall be separated into three inspection cycles (40-month, 80-month, and 120-month).

See Table 3.0-1 for important cycle and interval date information.

1084(207)

1/3-SI-4.6.G Page 3'

y nd of the inspection interval, the required examinations shall be performed in accordance with the following schedule.

Reactor Recirculation Pumps Class:

Function Provides a variable reactor power rate by varying core coolant flowrate.

Test Re uirement:

Visual examination of pump internal pressure boundary

surfaces, examination category B-L-2.

Basis for Relief:

During maintenance, if required, visual examination of the recirculati.on pump internal pressure boundary surface is performed and documented under existing plant procedures.

In the absence of required maintenance, as is the case with the recirculation pumps at Browns Ferry during the first 10-year interval, disassembly of a recirculation pump solely to perform a visual examination of internal surfaces is impractical.

This would represent unnecessary exposure of employees to high radiation and contamination areas and excessive expense to TVA.

Disassembly of this pump could require transport of the motor outside of containment; consequently, a

possibility of damage to the pump, pump motor, or other safety-related equipment exists.

Time required for this major task of disassembly, examination, and reassembly would 'consume at least three weeks of 24-hours-per-day work.

Radiation dose rates of the pump exterior will average 10-20 rem/hour.

This would result in a cumulative dose of between 100 and 300 man-rem.

The benefit received from this major effort is minimal considering employees

exposure, potential damage to safety-related equipment, and cost.

Relief from the visual examination B-L-2 requirement is, therefore, requested.

Alternate Inspection:

A.

None planned.

As long as the temperatures are as specified recirculation pump manual, no routine visual examination is flows, pressure and in the Byron-Jackson disassembly for recommended.

B.

Conduct the required Code visual inspection of the interior during the cycle 6 outage.

Alternate Monitoring:

A.

Install monitoring instrumentation on each pump for pump shaft vibration caused by mechanical fatigue-driven crack growth with appropriate control room instrumentation.

B.

Install monitoring instrumentation for contamination of component cooling water (COW) by reactor coolant water caused by crack growth in the pump covers to the extent that a leak path develops between the two systems with appropriate control room instrumentation.

Visual examination of internal pressure boundary

surfaces, examination category B-M-2.

Basis for Relief:

During routine maintenance, visual examinations of valve body internal pressure boundary surfaces are performed and documented under existing plant administrative procedures.

If no valve within a group has been disassembled for maintenance as the end of the interval approaches, relief from the visual examination B-M-2 requirements is requested.

The attachments hereto present the valve groups requiring visual examination and the specific groups for each Browns Ferry Nuclear Plant unit for which relief is requested.

Alternate Inspection:

If no valves from a particular group have been disassembled as the end of the interval approaches, the valves comprising that group shall be visually examined for leakage when the system pressure tests (IWA-5000) are conducted in accordance with the requirements for Category B-P.

Integrally-Welded External Support Attachments for Piping and Valves Class:

Function Support components.

Test Re uirement:

Volumetric examination of the support attachment

welds, examination categories B-K-1.

Basis for Relief:

During the first Browns Ferry baseline inspection, the ultrasonic examinations of the integrally-welded Class 1 supports were meaningless because of the lack of penetration indications that existed for the full length of the support welds.

The supports were fabricated to ANSI B31.1.0 and General Electric Company specification 21A2100.

The GE specification required a

full penetration weld and surface examination requirements, which would not verify penetration.

The TVA Division of Engineering Design has taken actual weld dimensions of randomly-chosen piping supports and compared the load capabilities of these welds as installed to the loads based on design the supports would see during operation.

As indicated in the attached analysis, all supports studied have high factors of safety in their load-carrying capability; therefore, we feel the integrally-welded supports on the primary coolant piping are acceptable as installed.

Further ultrasonic examinations of these supports would. be meaningless.

Alternate Inspection:

Class 1 integrally-welded supports will be liquid penetrant examined in place of ultrasonic examinations.

The liquid penetrant examinations performed during each inspection interval will cover 25 percent of the integrally-welded supports.

1/3-S1-4.6.G Page 140 FILE NOTE DETERMINATION OF ACOUSTIC PROPERTIES OF VARIOUS CALIBRATION BLOCKS FOR USE IN INSERVICE INSPECTIONS AT BROWNS FERRY NUCLEAR PLANT.

During recent metallurgical examinations of calibration blocks used for baseline and inservice inspections at Browns Ferry, it was shown that four calibration blocks were not made from material of the same or equivalent P'number as the material that was examined.

Since this same or equivalent P number is required by Appendix IX of Section III of the ASME Boiler and Pressure Vessel Code, it was necessary to determine the acoustic properties of these four blocks with respect to material of the components.

Calibration blocks BF 11Cy BF 12Cy BF 13'nd Automation Industries AISI 4340 3-inch area amplitude block S.N.

1219 were used to examine materials of different P number.

The velocity and attenuations in these blocks were compared to the material they were used to examine as described in the following paragraphs.

Block,BF-llC was made'rom A515 grade 70 material while block BF-12C was made from A515 grade 55 material.

Both blocks were used to calibrate for A533 grade B material.

To demonstrate similarity, both blocks were compared to BF-10C, which is A533 grade B, for sound velocity and attenuation.

Using a Krautkramer type USIP-1CW ultrasonic flow detector, with an Automation Industries 2.25 MHz, type SFB 3/8-inch effective diameter

crystal, these back reflections from the 3.007-inch side of BF-12C were placed at the 3-, 6-, and 9-inch locations on the CRT graticule.

The crystal was then placed on the 3.992-inch of BF-11C.

Back reflections were observed at the 4-and 8-inch locations on the CRT graticule.

After this, the crystal was placed on the 4.032-inch side of BF-10C.

The first back reflections occurred between 4.000 and 4.050 inches and was interpreted to be 4.025 inches.

The second back reflection occurred between 8.000 and 8.100 inches and was interpreted to be 8.050 inches.

By the above process, it was determined that the velocity of sound was essentially the same through all three blocks.

To check attenuation an Automation Industries 5 MHz, type SFB, 3/8-inch effective diameter crystal was placed on the 4-inch thickness of BF-10C.

With the first back reflection set at 60 percent of full scale, the gain setting read 42 dB.

The gain was then increased to 51 dB to bring the second back reflection up to 60 percent scale height.

This gave an attenuation of 0.75 dB/inch.

This procedure was repeated on the 4-inch side of BF-11C with a change in dB from 58 to 42.

This gave an attenuation of 2.5 dB/inch.

The 2.2-inch side of BF-12C was then evaluated and a change in dB from 36 to 45 was necessary to bring the second back reflection up to 60 percent full scale.

This gave an 1084{207)

'1/3-SI-4.6.G Page 141 attenuation of 1.5 dB/inch.

All three measurements were reported three times with the same results.

It can be seen that calibration with BF-llC or BF-12C would give a more sensitive examination than is required.

BF-13, which is A437 grade B4C, is used to calibrate for A540 grade B23 material.

Using an Automation Industries 5-MHz, type SFB, 3/8-inch effective diameter crystal, the 100-inch scale of the ultrasonic instrument was checked for linerity using an Automation Industries'ISI 4340 3-inch block S.N.

1219 and a 65.6-inch reactor closure head stud made from A540 grade B23 material.

When the crystal was placed on the 69-inch BF-13, a back reflection was seen within 1 inch of the desired

reading, which is as close as the scale can be resolved on the 100-inch scale.

To check for attenuation, the back reflection of BF-13 was set at 80 percent scale height with a gain setting of 43 dB.

The same amplitude was obtained on the reactor closure head stud using 42 dB.

On the basis of the above tests, BF-13 is considered a satisfactory calibration block for A540 grade B23 material.

The Automation Industries'ISI 4340 3-inch area amplitude block S.N.

1219 is also used for examining recirculation pump nuts made from A194 Cl.

24 material.

Both nut and block were 3 inches thick.

Both distances measured 3 inches by using the USIP-1CW Krautkramer ultrasonic flow detector with an Automation Industries 5 MH, type SFB, 3/8-inch effective diameter crystal.

Attenuation was checked on the nut by setting the first back reflection to 50 percent of full scale and then bringing the second back reflection up to 60 percent by using the gain control.

A total of 12 dB was required to do this, giving a material attenuation of 2 dB/inch.

This was repeated for the calibration block with identical results.

These two materials are therefore considered similar with respect to velocity and attenuation.

Class:

Function:

Pressure retaining nozzle welds in vessels Test Re uirement:

Volumetric examination of nozzle-to-vessel attachment welds, examination category C-B.

Basis for Relief:

The RHR heat exchangers nozzle-to-vessel attachment weld is covered by a reinforcement ring (shown in the attached sketch) which does not allow access to any of the attachment weld.

Alternate Inspection:

The reinforcement ring welds are accessible and will be given a surface examination.

Two reinforcement rings on each unit will be examined over the 40-year inspection interval in accordance with IWC-2411 on ASME Section XI.

~Com onente:

Pressure-retaining bolting Class:

Ins ection Re uirements:

Visual, surface, and volumetric examination of pressure-retaining bolting exceeding one inch in

diameter, examination category C-D.

Basis for Relief:,

Examination of class 2 pressure-retaining bolting in accordance with the Summer 1975 Addenda of Section XI exceeds inspection requirements for class 1 pressure-retaining bolting.

We do not feel an increased level of. safety is obtained from a more restrictive examination of class 2

components.

An examination program for class 2

pressure-retaining bolting similar to that for class 1 would be desirable.

This type of examination has been incorporated in later additions of the code which Browns Ferry will be required to meet in the future.

Alternate Inspection:

Class 2 pressure-retaining bolting exceeding two inches in diameter shall be volumetrically examined in accordance with Table IWC-2500-1, examination category C-D of the 1977 Edition, Summer 1979 Addenda of Section ZI.

Pressure-retaining bolting two inches or less in diameter will not be examined.

Ultrasonic calibration and examination of welded piping components.

III-4450 Inaccessibility Welds.

The ultrasonic examination (IWA-2232(b),

IWA-2232(c), and Appendix III) and evaluation (IWA-3000) of piping welds is being updated to the 1977 Edition, Summer 1978 Addenda of ASME Section XI to provide state-of-the-art methods for both.

There are existing requests fo" relief (addressed to the 1974 Edition of the ASME Code) from the test requirements listed above.

We do not believe the existing requests for relief (ISI-8 and ISI-10) affect the overall purpose of updating the examination and evaluation techniques.

Alternate Inspection:

Ve request relief to remain to the 1974 Edition, Summer 1975 Addenda and the existing requests for relief for calibration block material, calibration

notches, and inaccessible welds.

As specified in ISI-8 and ISI-10.
