,.o REACTOR COOLANT SYSTEM 3/4.4.3 REACTOR COOLANT SYSTEM LEAKAGE LEAKAGE DETECTION SYSTEMS LIMITING CONDITION FOR OPERATION coabinations 3.4.3.1 The following reactor coolant system leakage detection system shall be OPERABLE:
The drywell atmosphere particulate or gaseous radioactivity monitoring a.
- system,
+
b.
The drywell floor drain sump and equipment drain sump flow monitoring system, and The upper drywell air coolers condensate flow rate monitoring system, or the c.
drywell floor drain sump flow monitoring systen.
APPLICABILITY: OPERATIONAL CONDITIONS 1, 2 and 3.
ACTION:
co.hinations With only two of the required leakage detection system.AOPERABLE, operation may continue for up to:
a.
