20555 RE:
St. Lucie Unit 2 Docket No. 50-389 In-Service-Inspection Plan Second Ten-Year Interval Relief Re uest 14 Su lement By letter dated May 4,
- 1995, NRC transmitted the safety evaluation approving the Second-Ten-Year Interval In-Service Inspection (ISI)
Plan for St. Lucie Unit 2. Relief request 14 was identified as an open item in that evaluation and was to be resolved by separate correspondence.
Subsequent conference calls with the NRC Project Manager identified the need for FPL to provide additional justification on the rescheduling of examinations in the relief request.
The modified relief request 14 including the additional information is Attachment 1.
Each request is specifically addressed in Attachment 2.
This additional information supports the FPL determination pursuant to 10 CFR 50.55a (a)(3) that the proposed alternatives would provide an acceptable level of quality and
- safety, and that compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.
Please contact us if there are any questions about this submittal.

Successive Inspections IWB-2420(a) and IWC-2420(a)
The sequence of component examinations established during the first inspection interval shall be repeated during each successive inspection interval, to the extent practical.
RELIEF REQUESTED:
Florida Power and Light Company (FPL) requests relief from repeating, the sequence of component examinations established during the first in-service inspection interval, allow an alternative to the requirements contained within Tables IWB-2412-1, IWC-2412-1, and to substitute like examinations on the same or similar lines when radiation dose rates can be lowered significantly. Substitutions to the extent practical will be in accordance with normal scheduling criteria.
BASIS FOR RELIEF:
Since FPL began performing in-service examinations, the rules for radiation
- exposure, safety, and the selection and scheduling of in-service examinations have changed significantly.
Examinations in the first in-service inspection interval on Class 1 and 2 components and systems were performed in accordance with the 1980 Edition through the Winter 1980 Addenda of Section XI prorated for the interval.
- Vessels, unlike piping systems are unique in that examination areas include several Examination Categories, Examination Item Numbers, and in the case of steam generators cover two Code Classes (Class 1
and Class 2
respectively).
Equal distribution of examinations over three inspection periods on individual vessels (Steam Generators, Pressurizer, etc.),
are complicated due to their unique size, reduction in required examination items and multiple Examination Categories.
Equal distribution imposes an undue hardship in the areas of radiation
- exposure, personnel
- access, multiple job interference, and adds additional cost without providing a
significant increase in the quality and safety of the plant.

LUCIE UNIT 2 SECOND INSPECTION INTERVAL RELIEF REQUEST NUMBER 14 Previous Examination Results The St. Lucie previous nondestructive (NDE) examination results performed on these same components during the first inspection interval have not identified any flaws that exceeded the acceptance criteria of Section XI, or identify results that would warrant considerati'on of not adjusting the sequence of the examinations, therefore modifying the ISI schedule would have no effect on the safe operation of the plant.
Radiation 10 CFR 20.1101(b) mandates FPL to reduce radiation exposure to as low as reasonably achievable.
In order to satisfy this requirement and other new regulations, FPL must re-evaluate every aspect of every job. Adjusting the sequence of examinations will allow FPL to minimize the amount of work being conducted in radiation areas, meet safety requirements, ALARA requirements, and still meet the intent of Section XI.
Adjusting the sequence of examinations reduce the need for personnel to prepare and examine components in essentially the same areas several times.
The radiation exposure, time, and manpower required to perform these tasks can be significantly reduced by changing the sequence of examinations and the areas to be examined.
St. Lucie has gone through one outage with this altered scheduling criteria.
Insulation Vessel insulation is of a size and shape that the removal process of examination area insulation usually requires a
substantial amount of additional insulation to be removed.
Adhering to the sequence of examinations established during the first interval would require FPL to remove and reinstall the same insulation and scaffolding on two or more occasions.
- Removal, storage and reinstallation of the insulation greatly increases the chances of insulation damage and includes additional man-rem and costs associated with the need for personnel to prepare and examine components in essentially the same area several times.
The radiation
- exposure, time, and manpower required to perform these tasks can be significantly reduced by changing the sequence of examinations and changing the areas to be examined.
Cost Reduction The cost associated with preparing vessels for selected examinations on the same component, within each inspection period in order to specifically satisfy the percentage requirements of Section XI, is an economic
- hardship, without a substantial compensating increase in the quality or safety of the unit.
('xamination Schedules While it is desirable to have examination schedules move forward in the interval (less than 10 years between successive examinations),
the wording of Inspection Program B makes this difficult. A review of Inspection Program B requirements show that it is weighted toward moving examinations to the end of the interval (opposite from USNRC desires.)
The maximum examinations allowed for credit during the 1st period is 34%. If the minimum examinations were performed during the 1st period (16%) and the maximum examined during the 2nd period (67%), then 51% of the interval exams could be performed during the 2nd period. This same thought process can be applied to the 3rd period.
When a sample size in a category is small, Inspection Program B requires examinations to be scheduled later in the interval. Since St. Lucie ISI examinations were originally scheduled one-third each period, it is not possible to move examination schedules forward without scheduling others later in the interval.

LUCIE UNIT 2 SECOND INSPECTION INTERVAL RELIEF REQUEST NUMBER 14 Inspection Program B allows up to 50% of the 10 year examinations to be performed during the 2nd or 3rd periods. Allowing this same latitude during the 1st period would enable FPL to perform examinations with a
more efficient schedule, reduce radiation exposure and costs, and meet USNRC desires to have the time frame between successive examinations not exceed 10 year intervals.
Substitutions - examination items scheduled may be substituted for items not previously scheduled in order to reduce the radiation levels.
All substitutions willmeet the selection criteria of the applicable Examination Category, (i.e. terminal ends, high stress welds, etc.),
and shall meet the percentage requirements of inspection program "B". Such changes will be noted in the summary report submittal.
Tables 14-1 through 14-10 provide listings of items'selected for adjustment by Examination Category and provides specific percentages to be achieved during the inspection interval and within each inspection period.
Table 14-11 provides a Category summary for all Code Categories.
ALTERNATIVE EXAMINATIONS OR TESTS:
FPL proposes to adjust the sequence of examinations established within the first inspection interval on the Reactor Pressure
- Vessel, Steam Generator and Pressurizer, such that all major examinations are performed at one time within a specified inspection period.
Where practical, FPL has adjusted the sequence of examinations, (additional items) within the same examination categoryg (Shutdown Cooling Water Heat Exchanger, Regenerative Heat Exchanger, etc.)
in order to minimize the variation in the percentage requirements of Inspection Program B.
FPL proposes the following alternatives:
Reactor Pressure Vessel All required examinations will be deferred to the 3rd inspection period, as allowed by IWB-2500-1, in conjunction with the 10-year automated examination activity, with the exception of the shell to flange weld from the seal side and the threads in base material which will be conducted in the First period.
Reactor Pressure Vessel Closure Head All required examinations will be performed in the First inspection period, which willminimize the percentage requirements over the inspection interval.
Steam Generator (primary and secondary sides)
- All required examinations will be performed in the 2nd inspection Period, and with the exception of those areas requiring examination on both generators, performed on steam generator 2A.
Pressurizer
- All required examinations will be performed in the 1st inspection Period.
Shutdown Cooling Water Heat Exchanger All required examinations will be performed in the 3rd inspection Period.
Regenerative Heat Exchanger - All required examinations will be performed in the 2nd inspection period.
The readjusted schedule proposed and the system pressure test will provide continued assurance of an acceptable level of quality and safety.

EXAMINATIONCATEGORY B-D Continued Notes:
Pressurizer Examination Category B-D examinations on the pressurizer during the first inspection interval were distributed between the 1st, 2nd and 3rd inspection periods.
The pressurizer is contained within the pressurizer cubical with limited access on both the top and bottom heads.
The pressurizer include such items as lifting lugs,
- manways, safety, relief and spray nozzles (top head) and the surge and heater nozzles (bottom head),
which are in close proximity of each other that makes distributing them equally over the interval impractical.
Code required coverage and limitations associated with the nozzle examinations are included within the USNRC approved Request for Relief 3. In addition FPL feels that the nozzles on the top head should receive a refracted longitudinal examination during the 1st period as a direct result of the conversation between FPL and USNRC Staff during the pressurizer nozzle repair activity.
16 Item will be examined during an earlier period.
