Basis Specification 15.i5.A.1 The Reactar Coolant System conditions of cold shutdown assure that no steam will be formed and hence there would be no pressure buildup in the containment if the Reactor Coolant System ruptures.

Specification 15.3.6.A.I.a.

The safety design basis for the containment is that the containment must withstand the pressures ,

and temperatures of the design basis LOCA without exceeding the design leakage rate. The

] design allowable leakage rate (L.) is 4:4Q% of containment air weight per day at 60 psig (P.).'"

Containment operability is maintained by limiting the overall containment leakage rate to within the design allowable leakage rate (L.). Prior to the first startup after perfenning a required Containment Leakage Rate Testing Program leakage test, however, the applicable leakage limits specified in TS 15.6.12.D.2 must be met. Compliance with Specificatbn 15.3.6.A.l.a. will ensure a containment conf'guration that is structurally sound and that will limit leakage to those leakage rates assumed in the safety analysis. i If penetration or air lock leakage results in exceeding L., Specification 15.3.6.A.l.a. shall be i entered simultaneously with the LCO applicable to the penetration or air lock with the excessive I

leakage. Once the overall containment leakage rate is rc. ored to less than L,, Specification 15.3.6.A.l.a. may be exited and operation continued in accordance with the applicable LCO.

Specification 15.3.6.A.I.a.(1) in the event the containment is inoperable, containment must be restored to operabie status within one hour. The one hour completion time provides a period of time to correct the problem commensun.te with the importance of maintaining containment integrity during plant operation.

This time period also ensures that the probability of an accident (requiring containment integrity) occurring during periods when containment is inoperable is minimal.

9 Ilasis The control room emergency filtration is designed to filtei control room atmosphere and makeup air during control room isolation conditions. liigh efficiency particulate (liEPA) filters are installed before the charcoal adsorbers to prevent clogging and to remove essentially all particulate material.

Charcoal adsorbers are installed to reduce the potential intake of radioactive iodine to the control room during accident conditions. If the system is fotmd to be inoperable, there is no immediate threat to the control room and operation may continue for a limited period of time.

Ibe three control functions that can serve to actuate control room emergency filtration.n. Manual initiation nldiation monitorLand CoplainmCnt isolation. The radiation monitor actuation function and containmentJsolation are_the_only automatic actuatienicatures assumed in analyses performego show that control room dose will remain within the limits of 10 CFR 50. Appendix A. GDC 19.. One of the two rpecified. radiation monitors must be operable to fulfill the operability reuultement for radiation 1nonito.r_ actuation becaustenly one radiation monitor must function to oroperly actuate the system. The manual initiation capability is in-htded to recognize the validity of this method of acjuation by an operator in an anticipatory manner for angxpected actuation of the system or polentially in a compensatory mannetfor a failure of the automatic function.

TheEimrry auxiliary building exhaust system is designed to filter the mr released from the crimary Rusiliary building and maintain a negative pressurch the primary auxiliary building in relation to the outside atmosphere and tht turbine bui! ding during the recirculation phase of a loss of coolant ntcident. Cnarcoal adsorbers are installed to reducq_theno.tential intake of radioactive iodine to the control room _during_the recirculation chase _of.ajoss of coolant accident.

l (2) Try to locate areas having strain concentrations by visual examination paying particular attention to the condition of tbc liner surface. Itecord the location of any areas having strain concentrations.

11. Shortly after the initial pressure test and at about or.e year after initial start-up, reexamine the areas located in section (A). Measure and record inward deformations. Record observations pertaining to strain contentrations.

C. If the difference in the measured inward deformations exceeds 0.25 inch (for a particular location) and'or changes in strain concentration exist, then an investigation will be made. The investigation will determine the cause and any necessary corrective action.

D. The surveillance program will only be continued beyond the one year after initial start up inspection if some corrective action was needed. If required, the frequency ofinspection for a continued surveillance program will be determined shortly aller the "one year after initial start up inspection".

E. In addition to the preceding requirements, temperature readings will be obtained at the locations where inward deformations were measurci Tempe ature measurements will also be obtained on the outside of the containment building wall.

13a_is The containment is designed for an accident pressure of 60 psig (" While the reactor is operating, the internal environment of the containr.1ent will be air at approximately atmospheric pressure and a temperature of about 105'F. With these initial conditions, the temperature of the steam air m!xture at the peak accident pressure of 60 psig is 286*F.

Prior to initial cperation, the containment was strength tested at 69 Psig and then leak-tested.

The design objective of this preoperational leakage rate test was established as 0.4% by weight per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at 60 psig. This leakage rate is consistent with the construction of the containment,* which is equipped with independent leak testable penetrations and contains channels over all containment liner welds, which v,ere independently leak tested during construction. Ilased on 60 psig containtnenlicak testinpctformed in 1997. an pretationa! leak rate limit of 0.2% by weight per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at 60 psig isjustifiet Unit 1 - Amendment No. 15.4.4 6 Unit 2 - Amendment No.

l Safety analyses have been performed on the basis of a leakage rate of 0.g40% by wdght per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at 60 psig. With this leakage rate and with minimum containment engineered safety systems tbr iodine removal in operation, i.e. one spray pump with sodium hydroxide addition, the public exposum would be well below 10 CFR 100 values in the event of the design basis accident?and control room rersonnel exnosure wculd be within the limits of 10 CFR 50 AnpendN A GDC 19.

The performance of periodic integrated leakage rate tests during plant life provide a current assessment of potential leakage from the containment in case of an accident that would pressurize the interior of the containment. These tests are performed in accordance with the Containment Leakage Rate Testing Program.

Periodic visual and physical inspection of the containment tendons is the method to be used to determme loss ofload-carrying capability because of wire breakage or deterioration. The tendon l

surveillance pregram specified in 15.4,4.11 is based on the recommendation of Regulatory Guide l.35 Rev. 3. Conta nment tendon structural integrity was demonstrated for both units at the end of one, three and eight years following the initial containment structural integrity test.

The pre stress lift-off test provides a direct measure of the load carryi,7 capability of the tendon.

A deterioration of the corrosion preventive properties of the sheathing filler will be indicated by a chmge in the physical appearance of the filler, if the surveillance program indicates, by extensive wire breakage, tendon stress strain relations, or other abnormal conditions, that the pre-stressing tendons are not behaving as expected, the abnormal conditions will be subjected to an engineering analysis and evaluation la accordance with Specification 15.4.4.ll.D to dsermine whether the condition could result in a significant adverse impact on the containment structural integrity. The specified acceptance criteria are such as to alert attention to the situation well.

before the tendon load carrying capability would deteriorate to a point that failure during a design basis accident might be possible. Thus, the :ause of the incipient deterioration could be evaluated and corrective action studied without need to shut down the reactor. If the engineering evaluation determines that the abnormal condition could result in a significant adverse impact on the containment structural integrity, an abnormal degradation situation will be declared and a report submitted to the NRC in accordance with the specifications.
