REACTOR COOLANT SYSTEM 3/4.4.5 ' STEAM GENERATORS LIMITING CONDITION FOR OPERATION 3.4.5 Each steam generator shall be OPERABLE.

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

With one or more steam generators inoperable, restore the inoperable steam generator (s) to OPERABLE status prior to increasing T,above 200*F.

SURVEILLANCE REOUIREMENTS 4 4.5.0 Each steam generator shall be demonstrated OPERABLE by performance of.

the following augmented inservice. inspection program and the requirements of Specification 4.0.5.

4.4.5.1 Steam Generator Samole Selection and Insoection - Each steam generater-shall be determined OPERABLE during shutdown by selecting and inspecting at least the minimum number of steam generators specified in Table 4.4-1.

4.4.5.2 Steam Generator Tube

• Samole Selection and Insoection - The steam generator tube minimum sample size, inspection result classification, and.the corresponding action required shall be as specified in Table 4.4-2.

The inservice inspection of steam generator tubes shall be performed at the fre-quencies specified in Specification 4.4.5.3 and the inspected tubes shall. be verified acceptable per the acceptance criteria of Specification 4.4.5.4.

When applying the expectations of 4.4.5.2.a through 4.4.5.2.c,' previous defects or imperfections in the. area repaired by the sleeve are not considered an area requiring reinspection. The tubes selected for each inservice inspection shall include at least 3% of the total number of tubes in all.' steam generators; the.

tubes selected for these-inspections shall be selected on a random basis except:

a.

Where experience in similar plants with similar water chemistry.

indicates critical areas to be inspected.:then at.least 50% of the tubes inspected shall be from these critical areas, b.

The' first sample of tubes selected for each inservice inspection

. (subsequent to the preservice inspection)af each steam generator:

shall include:

• When referring to a steam generator tube, the sleeve shall be considered a part of the tube if the tube has been re' paired per Specific ~ tion 4.4.5.4.a.10.

s SURVElttANCE REOUIREMENTS (Continued) 4.4.5.3 Insoection Freauencies - The above required inservice inspections of steam generator tubes shall be performed at the following frequencies:

The first inservice inspection-shall. be performed after 6 Effective i

a.

Full Power Months but within 24' calendar months cf. initial i

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, not.

i including the preservice inspection, result in all inspection results falling into the C-1 category or if two consecutive inspections i

demonstrate that previously observed degradation has not continued-and no additional degradation has occurred, the inspection interval.

may be extended to a maximum of once per 40 months; 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 e

shall apply until the subsequent inspections satisfy the criteria of, Specification 4.4.5.3a.; the interval may then be extended to a maximum of once per 40 months; and Additional,. unscheduled inservice inspections shall be performed on c.

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:

3)

Reactor-to-secondary tube leaks (not including leaks originating from tube-to-tube sheet welds) in. excess of the limits of Specification 3.4.6.2c., or 2)

A seismic occurrence greater than the Operating Basis

farthquake, or 3)

A Condition IV loss-of-coolant accident' requiring' actuation of the Engineered Safety Features, or 4)

A Condition IV main steam line or. feedwater line break..

TABLE 4.4-1 MINIMUM NUMBER OF STEAM GENERATORS TO BE INSPECTED DURING INSERVICE INSPECTION i

Preservice Inspection Yes x

No. of Steam Generators per Unit Four first Inservice Inspection Two Second & Subsequent Inservice Inspections One' TABLE NOTATION 1.'

The inservice inspection may be limited to one steam generator on a rotating schedule encompassing 3 N % of the tubes (where N is the.

number of steam generators in the plant) if the results of the first or previous inspections indicate that all steam generators are performing in a like manner. Note that under some circumstances, the operating conditions in one or more steam generators may be found to be more severe than those in other steam generators. Under such circumstances the sample sequence shall be modified to inspect the most severe conditions.

Each of the other two steam generators not inspected during the first inservice inspections shall be inspected during the second and third inspections. The fourth and subsequent inspections shall follow the instructions described above.
