The results of each sample inspection shall be classified into one of the following three categories:
Category Inspection Results-C-1 Less than 5% of the total tubes inspected are degraded tubes and none of the inspected tubes are defective.
C-2 One or more tubes, but not more than 1% of the total tubes inspected are defective, or between 5% and 10% of the total tubes inspected are degraded tubes.

- a. The first inservice inspection shall be performed after 6 Effective ,
Full Power Months but within 24 calendar months of initial criticality.
Subsequent inservice inspections shall be performed at intervals of not less than 12 nor more than 24 calendar months after the previous inspection. If two consecutive inspections following service under '
AVT conditions, not including the preservice inspection, result in all inspection results falling into the C-1 category or if two consecutive inspections demonstrate that previously observed degra-dation has not continued and no additional degradation has occurred, the inspection interval may be extended to a maximum of once per 40 months; .
i b. If the results of the inservice inspection of a steam generator conducted in accordance with Table 4.4-2 at 40-month intervals fall in Category C-3, the inspection frequency shall be increased to at least once per 20 months. The increase in inspection frequency shall apply until the subsequent inspections satisfy the criteria of
, Specification 4.4.5.3a; the interval may then be extended to a f maximum of once per 40 months; and i c. Additional, unscheduled inservice inspections shall be performed on
! each steam' generator in accordance with the first sample inspection specified in Table 4.4-2 during the shutdown subsequent to any of the following conditions:
- 1) Reactor-to-secondary tubes leaks (not including leaks originating from tube-to-tube sheet welds) in excess of the limits of -
Specification 3.4.6.2,
- 2) A seismic occurrence greater than.the Operating Basis Earthquake,
- 3) A loss-of-coolant accident requiring actuation of the Engineered Safety Features, and
- 4) A main steam line or feedwater line break.

REACTO'1 COOLANT SYSTEM SURVEILLANCE REQUIREMENTS (Continued) 4.4.5.4 Acceptance Criteria
- a. As used in this specification:
- 1) Imperfection means an exception to the dimensions,-finish or contour of a tube from that required by fabrication drawings or
- specifications. Eddy-current testing indications below 20% of the nominal tube wall thickness, if detectable, may be considered as i
imperfections;
- 2) Degradation means a service-induced cracking, wastage, wear or i
general corrosion occurring on either inside or outside of a tube; i
- 3) Degraded Tube means a tube containing imperfections greater than or equal to 20% of the nominal wall thickness caused by degradation; 3
- 4) % Degradation means the percentage of the tube wall thickness affected or removed by degradation; 1
- 5) Defect means an imperfection of such severity that it exceeds the i plugging limit. A tube containing a defect is defectiva;
- 6) Plugging Limit means the imperfection depth at or beyond which the I
tube shall be removed from service and is equal to 40% of the nominal tube wall thickness. [This definition does not apply to
- the area of the tubesheet region below the F* distance.]
- 7) Unserviceable describes the condition of a tube if it leaks or contains a defect large enough to affect its structural integrity in the event of an Operating Basis Earthquake, a loss-of-coolant accident,.or a steam line or feedwater line break as specified in 4.4.5.3c, above;
- 8) Tube Inspection means an inspection of the steam generator tube from the point of entry (hot leg side) completely around the U-bend to the top support of the cold leg; and i
NOTE 1: The application of F* (the bracketed sentence) expires ninety days following the startup of each Unit following the fifth refueling outage on each respective unit.

- 9) Preservice Inspection means an inspection of the full length of each tube in each steam generator performed by eddy current techniques prior to service to establish a baseline condition of the tubing. This inspection shall be performed after the field hydrostatic test and prior to initial POWER OPERATION using the equipment and techniques expected to be used during subsequent inservice inspections.
- 10) F* Distance is the distance into the tubesheet from the top face of the tubesheet or the top of the last hardroll, whichever is lower (further into the tubesheet) that has been conservatively chosen to be 2 inches.
- b. The steam generator shall be determined OPERABLE af ter completing the corresponding actions (plug all tubes exceeding the plugging limit and all tubes containing through-wall cracks) required by Table 4.4-2.
4.4.5.5 Reports
- a. Within 15 days following the completion of each inservice inspection of steam generator tubes, the number of tubes plugged in each steam generator shall be reported to the Commission in a Special Report pursuant to Specification 6.9.2;
- b. The complete results of the steam generator tube inservice inspection shall be submitted to the Commission in a Special Report pursuant to Specification 6.9.2 within 12 months following the completion of the inspection. This Special Report shall include:
- 1) Number and extent of tubes inspected,
- 2) Location and percent of wall-thickness penetration for each indication of an imperfection, and
- 3) Identification of tubes plugged.

REACTOR COOLANT SYSTEM l BASES 3/4.4.4 RELIEF VALVES The power-operated relief valves (PORVs) and steam bubble function to relieve RCS pressure during all design transients up to and including the design step load decrease with steam dump. Operation of the PORVs minimizes the undesirable opening of the spring-loaded pressurizer code safety valves. Each PORV has a remotely operated block valve to provide a positive shutoff capability should a relief valve become inoperable.
3/4.4.5 STEAM GENERATORS The Surveillance Requirements for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS will be maintained. The program for inservice inspection of steam generator tubes is based on a modification of Regulatory Guide 1.83, Revision 1. Inservice i inspection of steam generator tubing is essential in order to maintain !
surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to design, manufacturing errors, or inservice conditions that lead to corrosion. Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.
The plant is expected to be operated in a manner such that the secondary coolant will be maintained within those chemistry limits found to result in negligible corrosion of the steam generator tubes. If the secondary coolant chemistry is not maintained within these limits, localized corrosion may likely result in stress corrosion cracking. The extent of cracking during plant operation would be limited by the limitation of steam generator tube leakage between the Reactor Coolant System and the Secondary Coolant System (reactor-to-secondary leakage = 500 gallons per day per steam generator). Cracks having a reactor-to-secondary leakage less than this limit during operation will have an adequate margin of safety to withstand the loads imposed during normal operation and by postulated accidents. Operating plants have demonstrated that
- reactor-to-secondary leakage of 500 gallons per day per steam generator can l readily be detected by radiation monitors of steam generator blowdown. Leakage in j excess of this limit will require plant shutdown and an unscheduled inspection, during which the leaking tubes will be located and plugged.
Wastage-type defects are unlikely with proper chemistry treatment of the
, secondary coolant. However, even if a defect should develop in service, it will be found during scheduled inservice steam generator tube examinations. Plugging will be reqvired for all tubes with imperfections in the free span region and i within theF* distance exceeding the plugging limit of 40% of the tube nominal wall l thickness. Steam generator tube inspections of operating plants have demonstrated l the capability to reliably detect degradation that has penetrated 20% of the original tube wall thickness. For tubes with imperfections found greater than two inches below the top of the tubesheet, plugging is not required.
