l ATTACHMENT A: OPERATION WITH REACTOR COOLANT PUMP POWER MONITORS I. CHANGE REQUEST Proposed Changes These changes address the current reactor refueling for Cycle V. The changes are supported in BAW-1767, Crystal River Unit 3 - Cycle 5 Reload Report, March 1983. Item II of this attachment lists the proposed Technical Specification changes.
These changes include:
- 1. Reactor core safety limits and trip setpoints for reactor thermal power and axial power imbalance.
- 2. Minimum boric acid and borated water volumes.
- 3. Reactor Regulating rod group insertion.
- 4. Reactor axial power shaping rod group insertion.
- 5. Reactor axial power imbalance limits
- 6. Reactor Coolant Pump Power Monitor operability response time requirements.
- 7. Shutdown Margin Requirements (not supported by BAW-1767 but by Attachment E, Item II).
Reasons for Proposed Changes Crystal River Unit 3 will operate in Cycle V with 76 fresh fuel assemblies. The Cycle V core has been designed with an increased cycle lifetime of 460 effective full power days (EFPD) and the incorporation of burnable poison rod assemblies to aid in reactivity control. As stated in BAW-1767, certain Technical Specifications require revision due to these fuel and thermal characteristics changing.
Safety Analysis of Proposed Changes The safety and licensing considerations for operation during Cycle V are described in B AW-1976. These proposed changes will bring the plant Technical Specifications into agreement with the applicable portions of BAW-1767 and insure that the plant will continue to operate in a safe manner.

2.2 LIMITING SAFETY SYSTEM SETTINGS BASES 2.2.1 REACTOR PROTECTION SYSTEM INSTRUMENTATION SETPOINTS The Reactor Protection System Instrumentation Trip Setpoint specified in Table 2.2-1 are the values at which the Reactor trips are set for each parameter. The Trip Setpoints have been selected to ensure that the reactor core and reactor coolant system are prevented from exceeding their safety limits. Operation with a trip setpoint less conservative than its Trip Setpoint but within its specified Allowable Value is acceptable on the basis that the difference between each Trip Setpoint and the Allowable Value is equal to or less than the drift allowance assumed for each trip in the safety analyses.
The Shutdown Bypass provides for bypassing certain functions of the Reactor Frotection System in order to permit control rod drive tests, zero power PHYSICS TESTS and certain startup and shutdown procedures. The purpose of the Shutdown Bypass RCS Pressure-High trip is to prevent normal operation with Shutdown Bypass activated. This high pressure trip setpoint is lower than the normal low pressure trip setpoint so that the reactor must be tripped before the bypass is initiated. The Nuclear Overpower Trip Setpoint of less than or equal to 5.0% prevents any significant reactor power from being produced. Sufficient natural circulation would be available to remove 5.0% of RATED THERMAL POWER if none of the reactor coolant pumps were operating.
Manual Reactor Trip The Manual Reactor Trip is a redundant channel to the automatic Reactor Protection System instrumentation channels and provides manual reactor trip capability.
Nuclear Overpower A Nuclear Overpower trip at high power level (neutron flux) provides reactor core protection against reactivity excursions which are too rapid to be protected by temperature and pressure protective circuitry.
During normal station operation, reactor trip is initiated when the reactor power level reaches 104.9% of rated power. Due to calibration and instrument errors, the maximum actual power at which a trip would be actuated could be 112% which was used in the safety analysis.
l O CRYSTAL RIVER - UNIT 3 B 2-4
( LIMITING SAFETY SYSTEM SETTINGS BASES RCS Outlet Temperature - High The RCS Outlet Temperature High trip less than or equal to 6180F prevents the reactor outlet temperature from exceeding the design limits and acts as a backup trip for all power excursion transients.
Nuclear Overpower Based on RCS Flow and AXIAL POWER IMBALANCE The power level trip setpoint produced by the reactor coolant system flow is based on a flux-to-flow ratio which has been established to accommodate flow decreasing transients from high power.
The power level trip setpoint produced by the power-to-flow ratio provides both high power level and low flow protection in the event the reactor power level increases or the reactor coolant flow rate decreases. The power level setpoint produced by the power-to-flow ratio provides overpower DNB protection for all modes of pump operation. For every flow rate there is a maximum permissible power level, and for every power level there is a minimum permissible low flow rate. Typical power level and low flow rate combinations for the pump situations of Table 2.2-1 are as follows:
- 1. Trip would occur when four reactor coolant pumps are operating if power is pV greater than or equal to 107% and reactor flow rate is 100%, or flow rate is less than or equal to 93.45% and power level is 100%.
- 2. Trip would occur when three reactor coolant pumps are operating if power is greater than or equal to 79.92% and reactor flow rate is 74.7%, or flow rate is less than or equal to 70.09% and power is 75%.
For safety calculations the maximum calibration and instrumentation errors for the power level were used.
CRYSTAL RIVER - UNIT 3 B 2-5
O 'i=irisc s^eerv svsraa sarriscS BASES The AXIAL POWER IMBALANCE boundaries are established in order to prevent reactor thermal limits from being exceeded. These thermallimits are either power peaking kw/f t limits or DNBR limits. The AXIAL POWER IMBALANCE reduces the power level trip produced by the flux-to-flow ratio such that the boundaries of Figure 2.2-1 are produced.
The flux-to-flow ratio reduces the power level trip and associated reactor power-reactor power-imbalance boundaries by 1.07% for a 1% flow reduction.
RCS Pressure - Low, High, and Variable Low The High and Low trips are provided to limit the pressure range in which reactor operation is permitted.
During a slow reactivity insertion startup accident from low power or a slow reactivity insertion from high power, the RCS Pressure-High setpoint isreached before the Nuclear Overpower Trip Setpoint. The trip setpoint for RCS Pressure-High, 2300 psig, has been established to maintain the system pressure below the safety limit, 2750 psig, for any design transient. The RCS Pressure-High trip is backed up by the pressurizer code safety valves for RCS over pressure protection is therefore, set lower than the set pressure for these valves,2500 psig. The RCS Pressure-High trip also backs up the Nuclear Overpcwer trip.
O o The RCS eressere-tow 1800 gsis, end RCS eressure-veriebie iew, <ii.39 Toet e -5037.8) psig, Trip Setpoints have been established to maintain the DNB ratio greater than or equal to 1.30 for those design accidents that result in a pressure reduction. It also prevents reactor operation at pressures below the valid range of DNS correlation limits, protecting against DNB.
Due to the calibration and instrumentation errors, the safety analysis used a RCS Pressure-Variable Low Trip Setpoint of (11.59 Tout F -5077.8) psig.
O V CRYSTAL RIVER - UNIT 3 B 2 LIMITING SAFETY SYSTEM SETTINGS BASES Reactor Containment Vessel Pressure - High The Reactor Containment Vessel Pressure-High Trip Setpoint 16 4 psig, provides positive assurance that a reactor trip will occur in the unlikely event of a steam line failure in the containment vessel or a loss-of-coolar.t accident, even in the absence of a RCS Pressure -
Low trip.
Reactor Coolant Pump Power Monitors In conjunction with the power / imbalance / flow trips, the Reactor Coolant Pump Power Monitors trip prevents the minimum core DNBR from decreasing below 1.30 by tripping the reactor due to more than one reactor coolant pump not operating.
A reactor coolant pump is considered to be not operating when the power required by the pump is 2190% or is & 19.5% of the nominal operating power. The nominal operating power decreases from when a pump is started during heatup and is pumping dense fluid (typically 7500 kW) to when a pump is operating at full power and is pumping'less dense fluid (typically 5500 kW). In order to avoid spurious trips during normal operation, the 190% trip setpoint (14000 kW) is based on the nominal operating power for a pump during heatup and the 19.5% trip setpoint (1075 kW) is based on the maximum time within which an RCPPM RPS trip must occur to provide protection for the four pump coastdown.
Florida Power has agreed to take credit for the pump overpower trip in order to assure that certain potential faults such as a seismically induced fault high signal will not prevent this instrumentation from providing the protective action (i.e., a trip signal).

7 REACTIVITY CONTROL SYSTEMS BASES 3/4.1.1.4 MINIMUM TEMPERATURE FOR CRITICALITY This specification ensures that the reactor will not be made critical with the Reactor Coolant system average temperature less than 525%0F. This limitation is required to ensure that (1) the moderator temperature coefficient is within its analyzed temperature range, (2) the protective instrumentation is within its normal operating range, (3) the pressurizer is capable of being in an OPERABLE status with a steam bubble, and (4) the reactor pressure vessel is above its minimum RTNDT temperature.
3/4.1.2 BORATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation. The components required to perform this function include (1) borated water sources, (2) makeup or DHR pumps, (3) separate flow paths, (4) boric acid pumps, (5) associated heat tracing systems, and (6) an emergency power supply from OPERABLE emergency busses.
With the RCS average temperature above 2000F, a minimum of two separate and redundant boron injection systems are provided to ensure single functional capability in the event an assumed failure renders one of the systems inoperable. Allowable out-of-service periods ensure that minor component repair or corrective-action may be completed without undue risk to overall facility safety from injection system failures during the repair period.
The boration capability of either system is sufficient to provide a SHUTDOWN MARGIN from all operating conditions of 3.0% A k/k after xenon decay and cooldown to 2000F. The maximum boration capability requirement occurs from full power equilibrium xenon conditions and requires either 6356 gallons of 11,600 ppm boric acid solution from the boric acid storage tanks or 43,478 gallons of 2,270 ppm borated water from the borated water storage tank.
l The requirements for a minumum contained volume of 415,200 gallons of borated
( water in the borated water storage tank ensures the capability for borating the RCS to the desired level. The specified quantity of borated water is consistent with the ECCS requirements of Specification 3.5.4. Therefore, the larger volume of borated water is specified.
With the RCS temperature below 2000F, one injection system is acceptable without i single failure consideration on the basis of the stable reactivity condition of the l reactor and the additional restrictions prohibiting CORE ALTERATIONS and l positive reactivity change in the event the single injection system becomes inoperable.
The boron capability required below 2000F is sufficient to provide a SHUTDOWN MARGIN of 3.0%Ak/k after xenon decay and cooldown from 2000F to 1400F. This l condition requires either .300 gallons of 11,600 ppm boron from the boric acid storage system or 1,608 gaDonsof 2,270 ppm boron from the borated water storage tank. To envelop future cycle BWST contained borated water volume requirements, a minimum volume of 13,500 gallons is specified.

(~ ATTACHMENT D: TWO YEAR CYCLE IMPACT I. CHANGE REQUEST Proposed Changes
- On pages 1-8,3/4 3-9 and 3/4 7-35 change "18 months" to "24 months".
4 On those pages listed in item II, change "18 months" to " refueling cycle".
Additionally, where the signs i ori appear, spell out the inequality rather than print the symbol.
- Reasons for Proposed Changes e
This change will update the Crystal River Unit 3 Technical Specifications to reflect a potential fuel cycle length of two years instead of 18 months. More importantly, this change will delete the necessity to perform a mid-cycle shutdown to perform the 18 month surveillances during the 2 year refuel cycle.
Safety Analysis Although this change does change the recommended surveillance frequency, this will not degrade plant safety. Daily, Monthly, Quarterly, etc.,
surveillances are performed on much of the equipment for which the 18 month surveillance is lengthened.
t If the surveillance frequency was not lengthened, a mid-cycle shutdown would be necessary to perform the surveillance, since most of the affected surveillances cannot be performed during normal operation. Plant shutdown only to perform surveillance is not practical from a safety or operating standpoint as it introduces unnecessary transients and non-operation time.
A two year surveillance frequency should not decrease the reliability of equipment because other periodic surveillances are still being performed.
