l 3/4. 4. 6 REACTOR COOLANT SYSTEM LEAKAGE LEAKAGE DETECTION SYSTEMS l
LIMITING CONDITION FOR OPERATION i
3.4.6.1 The following Reactor Coolant System Leakage Detection l
Systems shall be OPERABLE:
a.
Either the Containment Atmosphere Gaseous or particulate Radioactivity Monitoring System, and b.
The Containment Drain Sump Level or Pumped Capaci-ty Monitoring System l
APPLICABILITY: MODES 1, 2,
3, and 4 l
ACTION:
i l
a.
With both the Containment Atmosphere Gaseous and
(
Particulate Radioactivity Monitors INOPERABLE, opera-tion may continue for up to 30 days provided the Containment Drain Sump Level or Pumped Capacity Moni-toring System is OPERABLE and gaseous grab samples of the containment atmosphere are obtained at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and analyzed for gross noble gas activity within the subsequent 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />; otherwise, be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD l

SURVEILLANCE REOUIREMENTS l
4.4.6.1 The Leakage Detection Systems shall be demonstrated OPERABLE by:
i a.
Containment Atmosphere Gaseous and Particulate Radioac-tivity Monitoring Systems-performance of CHANNEL CHECK, j
l CHANNEL CALIBRATION, and ANALOG CHANNEL OPERATIONAL l
TEST at the frequencies specified in Table 4.3-3, and j
i b.
Containment Drain Sump Level and Pumped Capacity Monitoring System-performance of CHANNEL CALIBRATION at i
least once per 18 months.
