Catawba Units 1 and 2 16.7-2-3 Revision 3

Seismic Instrumentation 16.7-2 BASES The FUNCTIONALITY of the seismic monitoring instrumentation ensures that sufficient capability is available to promptly determine the magnitude of a seismic event and evaluate the response of those features important to safety. This capability is required to permit comparison of the measured response to that used in the design basis for the facility to determine if plant shutdown is required pursuant to Appendix A of 10 CFR Part 100. The instrumentation is consistent with the recommendations of Regulatory Guide 1.12, "Nuclear Power Plant Instrumentation for Earthquakes", Revision 2.

The seismic monitoring instrumentation system records seismic data acquired by five triaxial accelerographs (at locations per Table 16.7-2-1, Items 1.a through 1 .e); each accelerograph consists of a solid state recording device (using static random access memory (SDRAM) storage) and an integral micro electro-mechanical sensor (or MEMS accelerometer).

All five accelerographs are connected to the network control center (NCC) 11 EECS 1000 located in the control room (on the 1MC8 back panel, near 1IEEVD 1000). The NCC provides a centralized location for: on-line system monitoring (including continuous self-checking of significant functions and power supply status); data retrieval from each accelerograph; data transfer (download) to the dedicated system computer 1 IEECO 9000 for required analysis purposes (i.e., analysis required following a seismic event); system status indications (associated with the NCC and all five accelerographs);

date/time synchronization (for each accelerograph); and generation of a common "start recording" trigger command (to all accelerographs) in the event that a trigger acceleration threshold is exceeded. System failures will result in an alarm condition on the NCC and a remote alarm sent to the Unit 1 Operator Aid Computer.

The two upper containment accelerographs (1IEEVD 1030 and 1IEEVD 1040) were excluded from the CHANNEL CHECK required by TR 16.7-2-1, since they are not used to generate the Operating Basis Earthquake (OBE) exceedance signal (indicated by the Unit 1 control room annunciator system).

The other three accelerographs were chosen since they are either: 1) located at the base of a Category 1 structure (1IEEVD 1010 and 1IEEVD 1020), consistent with measurement locations per Regulatory Guide 1.12 guidance; or 2) within the control room area (11 EEVD 1000), to confirm that the seismic event was felt by operators.

Radiation Monitoring for Plant Operations 16.7-10 Table 167'-10-1 Notes (a) When venting or purging from containment to the atmosphere, the trip setpoint shall not exceed the equivalent limits of SLC 16.11-6 in accordance with the methodology and parameters in the ODCM. When not venting or purging in Modes 5 or 6, the alarm setpoint concentration (pCi/ml) shall be such that the actual submersion dose rate would not exceed 5 mR/hr without alarm. When not venting or purging in Modes 1 through 4, the alarm setpoint shall be no more than 3 times the containment atmosphere activity as indicated by the radiation monitor.

(b) For EMF-46A & B: The EMF monitor associated with the operating Component Cooling Water System train shall be FUNCTIONAL. This requirement is based on the existence of an interlock which blocks the EMF loss of flow alarm from being received in the control room when the associated train pump motor(s) are not running.

(c) The setpoint is as required by the primary to secondary leak rate monitoring program.

Catawba Units 1 and 2 16.7-10-9 Revision 3

Radiation Monitoring for Plant Operations 16.7-10 BASES The FUNCTIONALITY of the radiation monitoring instrumentation for plant operations ensures that: (1) the associated action will be initiated when the radiation level monitored by each channel or combination thereof reaches its setpoint, (2) the specified coincidence logic is maintained, and (3) sufficient redundancy is maintained to permit a channel to be out of service for testing or maintenance. The radiation monitors for plant operations senses radiation levels in selected plant systems and locations and determines whether or not predetermined limits are being exceeded. The radiation monitors send actuation signals to initiate alarms or automatic isolation action and actuation of emergency exhaust or ventilation systems. Some of the final actuations are dependent on plant condition in addition to the actuation signals from the radiation monitors.

Operation of the Component Cooling Water System (KC) Train A with the Train A Radiation Monitoring Systeml(EMF) monitor non-functional and relying'on the Train B EMF monitor for detection of radioactivity is not permissible. Likewise, operation of the KC Train B with the Train B EMF monitor non-functional and relying on the Train A EMF monitor for detection of radioactivity is not permissible. This is due to the' interlock between the EMF monitor low-flow alarm and the operation of the KC pump motors on the same train. The EMF monitor in the operating KC pump train must be FUNCTIONAL, or the compensatory measures taken as specified.

Initiation of the Containment Purge Exhaust System (CPES) with EMF-39 non-functional is not permissible. The basis for Required Actions B.1 and B.2 is to allow the continued operation of the CPES with EMF-39 initially FUNCTIONAL. Continued operation of the CPES is contingent upon the ability of the affected unit to meet the requirements as noted in Required Actions B.1 and B.2.

Radioactive Gaseous Effluent Monitoring Instrumentation 16.11-7 BASES The Radioactive Gaseous Effluent Monitoring Instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The Alarm/Trip Setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the Alarm/Trip will occur prior to exceeding the limits of 10 CFR Part 20. The FUNCTIONALITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50. The sensitivity of any noble gas activity monitor used to show compliance with the gaseous effluent release requirements of SLC 16.11-8 shall be such that concentrations as low as 1 x 10-6 pCi/cc are measurable.

Initiation of the Containment Purge Exhaust System (CPES) with EMF-39 non-functional is not permissible. The basis for Required Actions F.1 and F.2.1 and F.2.2 is to allow the continued operation of the CPES with EMF-39 initially FUNCTIONAL. Continued operation of the CPES is contingent upon the ability of the affected unit to meet the requirements as noted in Required Actions F.1 and F.2.1 and F.2.2.
