REACTOR C0OLANT SYSTEM BASES 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 l nature and cause of any tube degradation so that corrective measures can be taken. l 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

~l limitation of steam generator tube leakage between the primary coolant system

, and the secondary coolant system (primary-to-secondary leakage = 0.10 GPM,

persteamgenerator). Cracks having a primary-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 primary-to-secondary leakage of 0.10
gallon per minute can readily be detected by radiation monitors of steam I generator blowdown. Leakage in excess of this limit will require plant shutdown and an unscheduled inspection, during which the leaking tubes will be located and i

plugged.

2 Wastage-type defects are unlikely with proper chemistry treatment of the '

secondary coolant. However, even if a defect should develop in service, it will i be found during scheduled inservice steam generator tube examinations.

i Plugging or sleeving will be required for all tubes with imperfections exceeding

the plugging limit of 40% of the tube nominal wall thickness. Sleeving repair will be limited to those steam generator tubes with a defect between the tube sheet and the first eggerate support. Tubes containing sleeves with imperfections exceeding the plugging limit will be plugged. Steam generator

. tube inspections of operating plants have demonstrated the capability to reliably detect degradation that has penetrated 20% of the original tube wall thickness.

Whenever the results of any steam generator tubing inservice inspection fall into Category C-3, these results will be immediately reported to the

! Commission pursuant to 10 CFR 50.72. Such cases will be considered by the Commission on a case-by-case basis and may result in a requirement for analysis, laboratory examinations, tests, additional eddy-current inspection,

and revision of the Technical Specifications, if necessary.

  • 3/4.2 POWER DISTRIBUTION LINITS BASES I 3/4.2.1 LINEAR HEAT RATE 1

The limitation on linear heat rate ensures that in the event of a LOCA, the peak temperature of the fuel cladding will not exceed 2200*F.

Either of the two core power distribution monitoring systems, the Excore
Detector Monitoring System and the Incore Detector Monitoring System, provide
adequate monitoring of the core power distribution and are capable of verifying

! that the linear heat rate does not exceed its limits. The Excore Detector Monitoring System performs this function by continuously monitoring the AXIAL SHAPE INDEX with two OPERABLE excore neutron flux detectors and verifying that the AXIAL SHAPE INDEX is maintained within the allowable limits specified in

! the Core Operating Limits Report using the Power Ratio Recorder. The power i dependent limits of the Power Ratio Recorder are less than or equal to the limits specified in the Core Operating Limits Report. In conjunction with the l use of the excore monitoring system and in establishing the AXIAL SHAPE INDEX l limits, the following assumptions are made: 1) the CEA insertion limits of ,

Spscifications 3.1.3.5 and 3.1.3.6 are satisfied, 2) the AZIMUTHAL POWER TILT l restrictions of Specification 3.2.4 are satisfied, and 3) the TOTAL UNR00DED

INTEGRATED RADIAL PEAKING FACTOR does not exceed the limits of Specification 3.2.3.

l The Incore Detector Monitoring System continuously provides a direct

measure of the peaking factors and the alarms which have been established for ,

- the individual incore detector segments ensure that the peak linear heat rates ,

l will be maintained within the allowable limits specified in the Core Operating l Limits Report. The setpoints for these alarms include allowances, set in the

conservative directions, for I) a flux peaking augmentation factor, 2) a measurement-calculational uncertainty factor, 3) an engineering uncertainty  ;

, factor, 4) an allowance for axial fuel densification and thermal expansion, and l 5) a THERMAL POWER measurement uncertainty factor specified in the Core

! Operating Limits Report. Note the Items (1) and (4) above are only applicable to fuel batches "A" through "L".

3/4.2.3 and 3/4.2.4 TOTAL UNRODDED INTEGRATED RADIAL PEAKING FACTORS FJ MQ AZIMUTHAL POWER TILT - T q l The limitations on FT and T are provided to 1) ensure that the assump-tions used in the analys[s for $stablishing the Linear Heat Rate and Local

assumptions used in the analysis establishing the DNB Margin LCO, and Thermal 4 Margin / Low Pressure LSSS setpoints remain valid _ during operation at the various allowable CEA group insertion limits. If F or T exceed their basic limitations, operation may continue under the addi$1onal @estrictions imposed by the ACTION statements since these additional restrictions provide adequate

j evidence of mechanical damage or progressive degradation due to design, eanufacturing 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 1 coolant will be maintaimd within those chemistry limits found to result in

negligible corrosion of the steam generator tubes. If the secondary coolant  !

l chemistry is not maintained within these limits, localized corrosion may likely l 4

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 primary coolant system and the secondary coolant system (primary-to-secondary leakage = 0.10 GPM, i per steam generator). Cracks having a primary-to-sesondary leakage less than j 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 primary-to-secondary leakage of 0.10 i

gallon per minute can readily be detected by radiation monitors of steam j i generator blowdown. Leakage in 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 I

be found during scheduled inservice steam generator tube examinations.
Plugging or sleeving will be required for all tubes with imperfections exceeding
the plugging limit of 40% of the tube nominal wall thickness. Sleeving repair
will be limited to those steam generator tubes with a defect between the tube j sheet and the first eggerate support. Tubes containing sleeves with i j imperfections exceeding the plugging limit will be plugged. Steam generator tube inspections of operating plants have demonstrated the capability to reliably j
detect degradation that has penetrated 20% of the original tube wall thickness.

! Whenever the results of any steam generator tubing inservice inspection j C-3, these results will be immediately reported to the fall into Category Commission pursuant to 10 CFR 50.72. Such cases will be considered by the

Commission on a case-by-case basis and may result in a requirement for

! analysis, laboratory examinations, tests, additional eddy-current inspection, j

and revision of the Technical Specifications, if necessary.

REACTOR COOLANT SYSTEM BASES 3/4.4.7 CHEMISTRY The limitations on Reactor Coolant System contaminants ensure that corrosion of the Reactor Coolant System is minimized and reduce the poten-tial for Reactor Coolant System leakage or failure due to stress corrosion.

Maintaining the concentrations of the contaminants within the Steady State Limits shown on Table 3.4-1 provides adequate corrosion protection to ensure the structural integrity of the Reactor Coolant System over the life of the plant. The associated effects of exceeding the oxygen, chloride and fluoride limits are time and temperature dependent. Corrosion studies show that operation may be continued with contaminant concentration levels in excess of the Steady State Limit s, up to the Transient Limits, for the specified limited time intervals without having a significant effect oc the structural integrity of the Reactor Coolant System. The time interval permitting continued operation within the restrictions of the Transient Limits provides time for taking corrective actions to restore the contaminant concentrations to within the Ste Wy State Limits.

The surveillance requirements provide adequate assurance that concentra-tions in excess of the limits wil' be detected in sufficient time to take corrective action.
