t FNP-2-M-068-1.2 EFFECTIVE DATE-The updated Unit 2 program goes into effect in March, 1989, during the Unit 2 sixth refueling outage and will continue through the third 40-month period of the first 10-year interval and will remain in effect through the first and second 40-month periods of the second ten-year interval until December 1, 1997, the-completion date for the r :ond 10-year interval for Unit 1.
Examinations performed under ection XI, 1983 Ecation through the Summer 1983 Addenda,_dur.'.g the third 40-month period of the first 10-year interval are required only for the remaining items necessary to complete the first 10-year interval. This update is not intended to be retroactive to any items previously examined during the first or second 40-month periods of the first 10-year interval. <
1.3 COMPONENT UPGRADING All-plant components have been reviewed to determine the appropriate classification for inservice inspection. ANSI, N-18.2 " Nuclear Safety Criteria for the Design of Stationary Pressurized Water Reactor Plants," is used as an acceptable-alternate to Safety Guide 26 in determining component quality group classifications.
It must be noted that the classification of components as ASME Class 1, 2, or 3 equivalent for inservice inspection does not.
Imply.'that the components were_ designed in accordance with'ASME requirements. The component design codes remain as stated in the Final Safety Analysis Report (FSAR).
1.4 SUBSEQUENT ISI PROGRAM REVISIONS .
In accordance with the NRC letter dated August 31, 1988, the Unit 2 Inservice Inspection Program for Class 1, 2, and 3 components will be reviewed near the end of the second 10-year interval for Unit 1 (December 1, 1997). At this time the Unit 2 program will be modified, as required, to bring it into compliance with the latest NRC-approved version of Section XI in effect at that time.

FNP-2-M-068 attached1 tabulations have been developed as a result of a design review. Should certain ASME Section XI Code requirements be ,
discovered to be impractical due to unforeseen reasons during the '
process-of performing inspections or tests, relief will be requested i from the specific Section XI Code requirement at that time.
' Radiation levels in certain. areas or of certain components may be found to-prohibit the access for operators or examiners to perform -
the examinations or tests described in this program. If radiation levels cannot be reduced and access is still restricted by t considerations of compliance with the requirements of Regulatory Guides 8.8 and 8.10, relief will be requested from the specific .
Section XI Code requirements and alternative-examination ,
requirements _will be proposed. ,

REllEF REQUEST TE:.2 RB:2 Component or I Relief Area: Dimensional requirements for calibration notches placed in ultrasonic calibration blocks used for piping and vessels less than or equal to 2 inches in thickness.
ALA 21 ALA-23 ALA-26 ALA 28 Requirement from Which Relief is Requested: Section XI, 1963 Edition with Addenda through Summer 1983 (piping systems), Code Case N 435 1 (which references the Winter 1985 Addenda for thin wall vessels), Appendix 111, paragraph 111 3430, requires that basic calibration blocks shall contain notches that are at least 1.0 inches long and 0.104t-0.009t2 + 10%/ 20% in depth.
Basis for Relief:
ALA 21 ALA 23: The notch depth is at 2% and should be 10%.
ALA 26: The notch is .125 in, under the required length of 1.0 inches.
ALA 28: The notch is .012 in. less than the 20% tolerance requirement for depth.
The only possible consequences of these discrepancies is that the sensitivity level of the ultrasonic instrument would be slightly higher than required, resulting in a more critical examination. Correcting these conditions on any of the above blocks would not be prudent and would be of questionable value when considering possible damage to the blocks by subjecting them to additional machining.
Alternate Examination: None; all blocks are acceptable for use as is.

Applicable examination volume is shown in Figure IWB-2500-8 and includes 100 percent of the weld length.
Basis for Relief: The configuration of the steam generator nostle-to-safe-end welds is shown in Attachment 10-1. Examination of these welds is limited both by no::le geometry and the presence of a weld-deposited clad overlay on the safe-end no::le interface. Ultrasonic examinations can be performed from the pipe side and the weld surface, but are severely limited from the no :le side by the rough, as-cast surface and the clad overlay.

Reference drawings APRl 3100, examination areas IRl and IR2, steam generators 2A, 2B, and 20, and D 356354, sheet I of 3.
Requirement from which Relief is -
Requested: ASME Code Item No. B3.140, Category B D, requires volumetric examination of the nozzle inside-radius section for steam generator nozzles. Figure IWB 2500 7 shows the applicable examination volume. Relief is !
requested from performing this examination for the inlet and outlet nozzles on all steam generators.
Basis for Relief: The steam generator primary side nozzles (Attachment 11.1) are integrally cast as part of the channel head; therefore, no welds exist which require volumetric examination. The steam generator nozzle inner radiused section cannot be volumetrically examined from the ,
outside of the nozzle or channel head because the rough, as-cast contact surface is not suitable for ultrasonic coupling and the geometrical configuration +
requires an excessively long test metal distance resulting in high ultrasonic attenuation. The areas inside of the nozzles and channel head are covered with-cladding in the "as-welded" condition; therefore, the associated surface contours and roughness do not provide the conditions necessary to perform the examination. Even with proper preparation of the inside surface for volumetric examination, an adequate examination of the area of interest (base metal just below the cladding) could not be achieved due to the resulting ultrasonic response at the clad-to base metal .
interface.
Alternate Examination: The inside surface of each steam generator primary side nozzle inner radiused section will be visually examined. The examination area will include the inner radius surface region shown in Section XI, Figure IWB 2500 7, to the extent practical.

R.,'vement from which ) lief is Requessad: Item No. F3.50, Category F-C, Table IWF-2500-1 and paragraph IWA-2214 of ASME Section XI, 1983 Edition, require that VT-4 visual examination shall be conducted to determine conditions relating to the operability of components such PS snubbers and spring loaded / constant weight hangers.
Also VT-4 testing confirms functional adequacy, verification of the setting, or freedom of motion, which may require operability testing.
Basis for Relief Operability testir.g was inapproiately included in VT-4 as an examination method.
Also, paragraph IWA-2214(b) from the 1983 Section XI code is inconsistent with industry visual examination practices. An inspector does net perform bench testing of snubbers / constant-load / spring type supports.
Thests activities are performed by maintenance tecraicians.

FNP-2-M-068 RELIEF REQUEST FNP-2 RR-17 Component or Relief Area Reference system for all welds and areas subject to surface or volumetric examination.
Requirement from which Relief is Requested: IWA-2600 of ASME Section XI requires the establishment of a reference system for all r welds and areas subject to surface or volumetric examination. This system shall permit identification of each weld, the location of each weld centerline, and marking at regular intervals along the length of each weld.
Basis for Relief: To perform actual marking of welds in order to identify each weld centerline, length locations, etc., would require many manhours of radiation exposure. Many of the welds are <
insulated and as such many manhours of radiation exposure would be required to remove and reinstall insulation just to facilitate marking. Also many manhours cf radiation exposure would be involved in ,

which Relief is 1 Requested: Items No. 01.20 and Cl.30, Category C A, Table IWC-2500 1 of ASME Section XI, require volumetric examination of pressure vessel head circumferential welds and tube sheet-to shell welda. The applicable examination volume is shown in figures IWC 2500-1 and -2, and includes essentially 100 percent of the weld length.
Basis for Relief: The regenerative heat exchanger shell is fabricated from centrifuga11y cast austenitic steel material which limits ultrasonic examination to the half node technicue. The geometric configuration of the weld surface anc the location of adjacent nozzles and supports provide limitations to the 1 extent of the examination coverage. Approximately 50 to 60 ,
percent of the required volume can be examined. !
Alternate l- Examination: Ultrasonic examination will be performed to the maximum extent practical (which is approximately 50 to 60 percent) on a best effort basis. Surface examination of all accessible surfaces within the examination boundaries will t also be performed to supplement volumetric examinations. ;

Basis for Relief: While in service these spray additive lines have an operating pressure of 15.psig and temperature of 100*F, which is well below the design conditions.of 210 psig pressure and 300'F temperature. Therefore, a. system hydrostatic test at 1.25 Psy would not provide a-moaningful tent. In addition, the '
hydrostatic test will involve handling of highly corrosive sodium hydroxide, which is i undesirable and hazardous to personnel safety.
..i Alternate Examination: A measured flow test in accordance with plant l Technical Specification paragraph 4.6.2.2d
[ will be conducted periodically to assure the !
leaktightness of these Class 3 components.

Requirement from a which Relief is Requested: Paragraph IWF-5400(b)(1) of ASME Section XI _
- requires test verification of snubbers for maximum drag during low velocity displacements.
i l Basis for Relief: Hydraulic snubbers are inherently l
inconsistent when this particular test is considered. The load required to initiate movement will vary considerably between identical snubbers. The break-away force s L required to initiate movement would be l determined by a number of variables (viscosity of hydraulic fluid, valve spring H rates, temperature, etc.), all of which have no. relevancy to snubber integrity. .While ,
l break-away force for mechanical snubbers is a l relatively consistent'value whose increase is
- related to snubber integrity, this is not the i
case with hydraulic snubbers. The manufacturers of hydraulic snubbers have not i
. recognized break-away force as a test variable that is relevant to snubber integrity in that they have not addressed this parameter in their technical information. .!

Additional sample testing is to continue 1 until all units within the sample have passed.
inservice testing.
Basis for Relief: The additional. sampling plan required by.
IWF-5400(c) is more restrictive than the existing expansj.n plan detailed in Farley Technical-Speci.1 cation 3/4.7.9c. The existing expansion plan detailed in 3/4.7.9c /?

Requirement from which Relief is Requested: Item No. C7.40, Category C-H, Table
IWC-2500-1 of ASME Section XI, requires a hydrostatic test of all Class.2 pressure retaining components once every 10-year inspection interval, in accordance with paragraph IWC-5222.=
Basis for Relief: Hydrostatic testing of the RCS is performed in mode 2 of the reactor plant shutdown. In .i this mode the plant Technical Specifications require that all solenoid valves on the RCS head vent be maintained closed. This being the case, hydrostatic testing of the portion t between these valves at this time would be a violation of the Technical Specifications.
Another way to hydrotest these lines would be to pressurize the line after the head'has been removed. This would require actuating solenoid valves Q2B13HV-2 and Q2B13HV-4 with the aid of a temporary electric power source. The work associated with actuating these valves, installing test connections, and performing the hydrostatic test would-
% require excessive radiation exposure (approx.
- e. 1.5 man-rem).
This level of exposure is unwarranted in view ,
of the minimal benefits gained by : testing this relatively small section of pipe which is approximately 6 inches long.
Alternate Examination: Functional operation of this system demonstrates structural integrity. Visual inspection will be performed while the system is at normal operating pressure to verify leaktightness.

three (3) hydrostatic tests forward one period. The original schedule for performing l
hydrostatic testing was based on dividing the systems to be tested into s i.ghteen (18) ,
