(d) The process liquid monitors shall normally be in service.
Adequate spare parts shall be on hand to allow necessary repairs to be made promptly. Alarms shall be set as specified in 6.4.1 (d).
Calibration of the " Radioactive Waste System Effluent to Canal" monitor shall be checked at least once a month.
Calibration of the remaining monitors shall be checked at least once every three months. Each day an anlysis shall be made of the previous 24-hour collection of discharge canal water.
(e) The area monitoring system shall normally be in operation; however, individual monitors may be taken out of service for maintenance and repairs. Adequate spare parts shall be on hand to allow necessary repairs to be made promptly. During monitor outages in normally accessible areas, temporary monitoring shall be provided if the remaining area monitors do not provide adequate coverage. Calibration of monitors shall be checked at least monthly, except for monitors in the main condenser area and the control rod drive room which are not normally accessible. Ala rm trip points shall be set at a radiation level approximately twice the normal maximum indicated radiation level, but normally not less than one decade above the lowest scale reading. The area monitor in the control rod drive room and the main condenser area will be made operable during periods of extended shutdown.
l Two films or TLDs, each with a sensitivity of 10mR, shall be provided at each site environmental monitoring station. During operation at stack release rates of 0.1 curie per second or less, at least five monitoring stations shall be provided. The films or TLDs at each station shall be replaced and analyzed at least monthly.
Operation at stack release rates above 0.1 curie per second shall not exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> without at least fifteen film or TLD monitoring stations in service. Two of these stations shall be on-site near the stack. The remaining additional stations shall complement the permanent stations but shall be located at greater distances from the stack. One film or TLD at each station shall be rplaced and analyzed at least every two weeks. The second film or TLD shall be replaced and analyzed monthly.
Under all stack release conditions, the film or TLD processor shall be instructed to report within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on all films or TLDs that might indicate abnormal exposures.
(f) Gamma dose-rate measuring instruments and neutron dose-rate mesuring instruments shall be provided for establishing permissible working limits. These instruments shall be calibrated at least once every three months.
(g) At least two reactor water level indicators in the Reactor Depressurizing System shall be operable during power operation.
