NOTES 1.TO MEET THE REQUIREMENTS OF THE RBS FIRE HAZARDS ANALYSIS, POWER IS REMOVED FROM VALVE 1B21*MOVF019 DURING NORMAL POWER OPERATION. THIS

CAUSES THE ASSOCIATED ANNUNCIATORS TO REMAIN ENERGIZED AND MASK OTHER

INPUTS TO THE PREVENTIVE MAINTENANCE TASK TO DISABLE THE INPUT FROM

THIS VALVE TO THE LOSS OF POWER AND TROUBLE ANNUNCIATORS SO THAT OTHER

INPUTS TO THE ANNUNCIATORS ARE NOT MASKED. THIS NOTE ALSO PERMITS A

PREVENTIVE MAINTENANCE TASK TO RE-ENERGIZE THE VALVE WHEN THE VALVE IS

REQUIRED TO BE OPERABLE.

2.TO MEET THE REQUIREMENTS OF THE RBS FIRE HAZARDS ANALYSIS, POWER IS

REMOVED FROM VALVE 1E12*MOVF009 DURING NORMAL POWER OPERATION. THIS

CAUSES THE ASSOCIATED ANNUNCIATORS TO REMAIN ENERGIZED AND MASK OTHER

INPUTS TO THE ANNUNCIATOR. A NOTE HAS BEEN ADDED TO THE APPROPRIATE

DRAWING TO PERMIT A PREVENTIVE MAINTENANCE TASK TO DISABLE THE INPUT

FROM THIS VALVE TO THE LOSS OF POWER AND TROUBLE ANNUNCIATORS SO THAT

OTHER INPUTS TO THE ANNUNCIATORS ARE NOT MASKED. THIS NOTE ALSO

PERMITS A PREVENTIVE MAINTENANCE TASK TO RE-ENERGIZE THE VALVE PRIOR

RBS USAR TABLE 7.5-2 (Cont)

Revision 4 8 of 18 August 1991 NOTES: 4 1 1. Even though River Bend Station (RBS) does not use an inerted containment; RBS takes exception to the 0 to 30 volume percent range of the hydrogen monitoring system as described in Reg. Guide 1.97. Use of the 0 to 10 volume percent range has been technically justified as the most useful range based on all operator actions being initiated at hydrogen concentration

values below 9 volume percent. For a detailed analysis of the hydrogen

control system, see Section 6.2.5.

1 4 2. The maximum design suppression pool temperature is 185°F; therefore, the instrument range is from 0°F to 200°F.

3. Regulatory Guide 1.97 classifies as Type B those variables that provide information to indicate if plant safety functions are being accomplished.

Type B, Category 1, is intended for key variables that directly indicate the accomplishment of a safety function and its importance to safety. Backup variables are generally Category 3. Neutron flux is the key variable for

measuring reactivity control.

The degree to which this variable is important to safety is another

consideration. The large number of detectors (i.e., source-range monitors

and intermediate-range monitors) driven into the core soon after shutdown makes it highly probable that one or more of the existing NMS detectors will

be inserted. There is little probability that there would be, simultaneously, a need for this measurement (in terms of operator action to

be taken) and an accident environment in which the NMS would be rendered inoperable. Further, the operator can always actuate the SLCS upon loss of

instrumentation.

Therefore, a rigorous Category 1 requirement is not justified when the purpose and use of the measurement are analyzed as they relate to the criterion of importance to safety. A Category 3 classification of this

variable fully meets the intent of Regulatory Guide 1.97.

4. Control rod position is indicated at latch position, full in, full out, withdrawn overtravel, inserted overtravel, and mid-position without a

specific number.

5. This capability is part of the post-accident sampling system (PASS). A description of the PASS is provided in Section 9.3.2.6. This variable is

measured by

RBS USAR TABLE 7.5-2 (Cont) 9 of 18 August 1988 laboratory instrumentation whose range is calibration dependent. 1 6. This plant measures reactor water level with a safety-related, wide-range detector that effectively covers the level from top of active fuel to high-level trip (L8). In addition, instrumentation meeting Regulatory

Guide 1.97, Category 1 requirements monitors the fuel zone levels.

7. The use of in-core thermocouples has been investigated, and an analysis of the heat transfer in a BWR fuel bundle during a core uncovery event was performed to determine the nature of the response of thermocouples to core

heatup. The thermocouples were assumed to be located in the in-core guide tubes and heated primarily by radiation from the fuel channels. Results of this analysis show that, for conditions typical of small break loss-of-coolant accidents, there is a delay of at least 10 minutes between

the start of core uncovery and the time when the thermocouple reads 45°F above saturation. It is also probable that operation of relief valves during a small-break LOCA would interfere with the thermocouples' operation and could render them useless. Therefore, this plant does not

use in-core thermocouples.

8. This station has a drywell equipment drain sump that collects identified leakage and two drywell floor drain sumps that collect unidentified

leakage, in the drywell.

1 Although the level of the drain sumps can be a direct indication of breach of the reactor coolant system pressure boundary, the indication is ambiguous, because there can be water in those sumps during normal

operation. There is other instrumentation that indicates leakage in the

drywell: a. Drywell pressure - Category 1.

b. Drywell temperature - Category 2.

c. Drywell gaseous/particulate radiation -

Category 1.

The drywell sump levels signal neither initiates automatic-protection control circuitry nor informs the

RBS USAR TABLE 7.5-2 (Cont)

Revision 16 10 of 18 March 2003 operator to take safety-related actions. All sumps have level detectors that provide only the following non- safety indications:

a. Continuous level indication.

b. Rate-of-rise indication.

c. High-level alarm (starts first sump pump).

d. High-high-level alarm (starts second sump pump).

Regulatory Guide 1.97 states that instrumentation should function during and after an accident. The drywell sump systems are deliberately isolated

at the primary containment penetration upon receipt of an accident signal to establish containment integrity. This fact renders the drywell-sump-level signal irrelevant. Therefore, by design, drywell-level

instrumentation serves no useful accident-monitoring function.

The Emergency Procedures use the RPV level and the drywell pressure as entry conditions for the Level Control Guideline. A small line break

causes the drywell pressure to increase before a noticeable increase in the sump level. Therefore, the drywell sumps provide a lagging versus early indication of a leak. Therefore, River Bend Station provides

Category 2 drywell drain sump level instrumentation. 16 8 9. The primary containment isolation valves are listed in Table 6.2-40; these valves have open-closed indication with the exception of E22-AOVF005, E51-AOVF065, and E51-AOVF066. Relief valves used as containment isolation

valves are not active power-operated valves and, therefore, do not have remote position indication (reference USAR Section 6.2.4.2 and NRC SER

dated June 30, 1986, letter RBC-34480, Section 3.3.20).

8 16 10. The usefulness of information obtained by monitoring the radioactive concentration or radiation level in circulating primary coolant, in terms of helping the operator in his efforts to prevent and mitigate accidents, has not been substantiated. The particular planned operating action to be

taken, based on monitoring this variable, is not specified in the Emergency Procedures. The critical actions that must be taken to prevent and mitigate a gross breach of fuel cladding are 1) shut down the reactor and 2) maintain water level. Monitoring radioactivity has no influence on

either of these actions.

RBS USAR TABLE 7.5-2 (Cont)

Revision 9 11 of 18 November 1997 The purpose of this monitor falls in the category of "information that the barriers to release of radioactive material are being challenged" and "identification of degraded conditions and their magnitude, so the operator

can take actions that are available to mitigate the consequences."

Additional operator actions to mitigate the consequences of fuel barriers

being challenged, other than those based on Type A and B variables, have not

been identified.

Regulatory Guide 1.97 specifies measurement of the radioactivity of the

circulating primary coolant as the key variable in monitoring fuel cladding

status during isolation of the NSSS. The words "circulating primary

coolant" are interpreted to mean coolant, or a representative sample of such coolant, that flows past the core. A basic criterion for a valid

measurement of the specified variable is that the coolant being monitored is coolant that is in active contact with the fuel, i.e., flowing past the

failed fuel. Monitoring the active coolant (or a sample thereof) is the

dominant consideration. The post-accident sampling system (PASS) provides a

representative sample which can be monitored.

The subject of concern in Regulatory Guide 1.97 is assumed to be an isolated NSSS that is shut down. This assumption is justified as current monitors in the condenser off gas and main steam lines provide reliable and accurate information on the status of fuel cladding when the plant is not isolated.

Further, the post-accident sampling system (PASS), once activated, provides

an accurate status of coolant radioactivity and, hence, cladding status. In the interim between NSSS isolation and operation of the PASS, monitoring of the primary containment radiation and containment hydrogen provides information on the status of the fuel cladding. Therefore, no Type C, Category 1 instrumentation is provided to measure the subject variable. 9 11. Wide Range Gas Monitors (WRGM) are installed at the three RBS identified release points. These monitors are identified as RMS-RE5A, -RE6A, and -

RE125 for monitoring Fuel Building Vent Exhaust, Radwaste Building, and Main

Plant Exhaust Duct respectively. The WRGM contains two sampling flow paths:

a high-flow-rate path in the low radiation range and a low-flow-rate path in

the mid/high radiation range. The particulate and charcoal filter

assemblies associated with the mid/high range have lead shielding, and are designed to be used for sampling during post-accident conditions. The WRGM

meets the requirements of NUREG 0578, NUREG 0237, and applicable standards and regulatory guides, including Reg. Guide 1.97-Post Accident Monitoring

Instrumentation. During a post-accident condition the mid/high path is used for sampling. The samples are analyzed at the laboratory for detecting

particulates and halogens including iodine. The combined detection range via sampling is 10

-11 to 10 2 Ci/cc. 9 RBS USAR TABLE 7.5-2 (Cont)

RBS has an acoustic monitoring system which does not provide a high resolution measurement of actual flow through an SRV. The system does provide for high resolution in detecting an open or leaking SRV. The system provides an SRV open light for flow rates in excess of 150 lbm/hr of steam leaking past an SRV and a resolution of -10 percent FS during

full flow conditions. 1 15. The standby liquid control system (SLCS) is manually initiated.

Flow-measuring devices are not provided for this system; the pump-discharge header pressure, which is indicated in the control room, indicates SLCS pump operation. Besides the discharge header pressure observation, the operator can verify the proper functioning of the SLCS by

monitoring the following:

a. Decrease in the level of the sodium pentaborate storage tank 1 b. Reactivity change in the reactor as measured by neutron flux and concentration of boron.

c. Motor contactor indicating lights; the use of these indications is believed to be a valid alternative to SLCS

flow indication.

Therefore, no direct indication of SLCS flow is provided for River Bend Station.

16. RBS is equipped with an electrically driven high-pressure core spray (HPCS) system rather than a steam-driven turbine high-pressure coolant injection (HPCI) system. Therefore, RBS does not measure this variable.

17. The cooling water temperature and flow to ESF components is interpreted as main temperature and flow at the headers. The service water system, described in Chapter 9, performs as follows: When pressure is available, the normal service water system functions. This normal service water system temperature and flow is monitored by a Category 3 instrument. Should the

pressure decrease, the standby service water system automatically begins to

operate; the temperature and flow instrumentation for this system meets Regulatory Guide 1.97, Category 2 qualification. The maximum anticipated temperature of the standby service water system at the pump discharge is

95°F. Therefore, the temperature range provided is from 0°F to 125°F.

20. The radiation monitoring system is a digital radiation monitoring system (DRMS) that is computer based. There are individual indicating recorders

in the main control room for these monitors.

21. RBS utilizes its area radiation monitors for personnel protection. The range specified in Regulatory Guide 1.97 is intended for use as trending

information to determine when operations personnel might enter an area for

equipment repair or maintenance. RBS has chosen a lower range interval

based on radiation protection considerations. Further, the 10- R/hr upper dose rate value specified by the guide will not provide the operations or support staff at RBS with information of any value with regard to

radiation-induced equipment damage.

22. Vent flow is measured and used by the offsite dose projection algorithm.

The vent flow rates are displayed via pushbutton and LED readout. The

display ranges are as follows:

Sensor Flow Rate Range (SCFM)

Nominal (SCFM) 1 1RMS*FE5A 9,000 - 10,000 10,000 1RMS*FEX, Y125 98,800 - 123,000 105,800 1RMS-FE6A 80,400 80,400 1

23. Meteorological data are supplied from the meteorological stations to the DRMS dose assessment system. This information is available in the TSC and EOF.

RBS USAR TABLE 7.5-2 (Cont) 18 of 18 August 1988 24. The RBS auxiliary building vent discharges through the common plant vent.

25. RBS utilizes a Mark III containment structure without an inerted atmosphere. Instrumentation to continuously measure the containment/drywell oxygen concentration is not furnished. RBS will rely upon its post-accident sampling system and onsite laboratory facilities to furnish control room operators and support staff with the subject

information in a timely fashion. 1 26. Total IRM range corresponds to a neutron flux range of 1x10 8 to 1.5x10 13 nV or to a range of 5x10

-4 to 10% RP. SRM range corresponds to a neutron flux range of 1x10 3 to 1x10 9 nV or to a range of 10

-7 to 10-3% RP. 1
