. CONTAINMENT SYSTEMS i
BASES l
144.6.1.7 CONTAINMENT VENTILATION SYSTEM' The 48-inch and 12-inch containment and hydrogen purge supply and exhaust
[
isolation vavles are required to'be locked closed during plant operations since these valves have not been demonstrated capable of closing ~during a LOCA or steam line break accident. Maintaining these valves locked closed during plant j
operation ensures that-excessive quantities of radioactive materials will not be
?
released via the Containment Ventilation System.' To provide assurance that these containment valves cannot be inadvertently opened, the valves are locked closed.
4 in accordance with Standard Review Plan 6.2.4 which includes ~ mechanical devices 1
{
to seal or lock the valve closed, or prevents power from being supplied to the valve operator.
4 I
j The use of the Containment Ventilation' System during' operations is restricted to the 18-inch pressure relief discharge isolation valves (with an effective' 3
j diameter of 3_ inches) since, these venting valves are capable of closing during a i
LOCA or steam line break accident.- Therefore, the Exclusion Area dose guideline-i i
of 10CFR100 would not be exceeded in the event of an; accident during containment
]
venting operation.
. Leakage integrity tests with a maximum allowable leakage rate for containment
]
ventilation valves will provide early indication of. resilient material seal degradation and will allow opportunity for repair before gross leakage failures c
could develop. The 0.60 L leakage limit of Specification 2.6.1.2b. shal1 not be j;
exceededwhentheleakagefatesdeterminedbytheLleakageintegritytestsof j~
these valves are.added to the previously determined total for all valves and penetrations subject to Type B and C tests.
l 3/4.6.2 DEPRESSURIZATION AND COOLING SYSTEMS 3/4.6.2.1 CONTAINMENT SPRAY SYSTEM j
i i
The OPERABILITY cf the Containment Spray System ensures that containment j
depressurization and cooling capability will be~available in the event of a LOCA
{
or steam line break.
The pressure reduction and resultant lower containment'
]
leakage rate are consistent with the assumptions used in-the safety analyses.
j.-
The Containment Spray System which is composed of redundant trains, provides j
post-acccident cooling of the containment atmosphere. However, the Containment i
Spray System also provides a mechanism for removing iodine from the containment atmosphere and therefore the time requirements for restoring an inoperable Spray l
Systc-m to OPERABLE status have been maintained consistent with that' assigned j
other. inoperable ESF equipment.

not degraded during the cycle. Flow and differential pressure are normal tests l
Since 4
'the containment spray pumps cannot be tested with flow through the spray headers, they are tested via a test line.
This test confirms one point on the anaytical pump curve and is. indicative of overall performance. Such inservice inspections confirm component OPERABILITY, trend performance, and detect incipient failures by abnormal performance.
The Frequency _of the surveillance is in accordance'with the Inservice Testing Program.
374.6.2.2 SPRAY ADDITIVE SYSTEM The OPERABILITY of the Spray Additive System ensures that sufficien't NaOH is added to the containment spray in the event of a LOCA. 'The limits on Na0H volume and concentration ensure a long term pH value of between 8.5 and 10.5 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and. minimizes the effect of chloride and. caustic stress corrosion on mechanical, systems and components. The contained _ solution volume limit includes an allowance for solution not usable because of-tank discharge line location or other physical characteristics.
These assumptions are consistent with the iodine removal efficiency assumed in the safety analyses.
The required indicated level band of 91% to 94% for the Spray Additive Tank corresponds to an analytical limit band of 4900 gallons to 5314 gallons, respectively, and includes a 3.36% measurement uncertainty.
i
'l 3/4.6.3 CONTAINMENT ISOLATION VALVES The OPERABILITY of the containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of a release'of radioactive material to the containment etmosphere or pressurization of the containment and is consistent with the requirements of General Design Criteria 54 through 57 of 10CFR50 Appendix A.
Containment isolation within the time limits specified for those isolation valves designed to close automatically ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA.
