RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS

Limiting Conditions For Operation Balti Spgeifications 3,0.1 through 3.0.4 establish the general requirements applicable to Limiting Conditions for Operation. These requirements are based on the requirements for Limiting Conditions for Operation stated in the Code of Federal Regulations. 10 CFR 50.36(c)(2)

"Limiting conditions for operation are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a limiting condition for

, operation of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the technical specification until the condition can be met."

SotcificAtlolL1dd establishes the Applicability statement within each individual specification as the requirement for when (i.e., in which l OPERATIONAL H0 DES or other specified conditions) conformance to the Limiting '

Conditions for Operation is required for safe operation of the facility. The ACTION requirements establish those remedial measures that must be taken within specified time limits when the requirements of a Limiting Condition for Operation are not met.

There are two basic types of ACTION requirements. The first specifies the

remedial measures that permit continued operation of the facility which is not further restricted by the time limits of the ACTION requirements. In this case, conformance to the ACTION requirements provides an acceptable level of safety for unlimited continued operation as long as the ACTION i requirements continue to be met. The second type of ACTION requirement l J specifies a time limit in which conformance to the conditions of the Limiting l l Condition for Operation must be met. This time limit is the allowable outage ,

j time to restore an inoperable system or component to OPERABLE status or for j restoring parameters within specified limits. If these actions are not

completed within the allowable outage time limits, a shutdown is required to ,

! place the facility in a HODE or condition in which the specification no '

longer applies. It is not intended that the shutdown ACTION requirements be >

used as an operational convenience which permits (routine) voluntary removal  !

of a system (s) or component (s) from service in lieu of other alternatives j

. that would not result in redundant systems or components being inoperable.

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Limiting Conditions For Operation Halu (Continued)

The specified time limits of the ACTION requirements are applicable from the ,

time it is identified that a Limiting Condition for Operation is not met.

The time limits of the ACTION requirements are also applicable when a system or component is removed from service for surveillance testing or investigation of operational problems. Individual specifications may include a specified time limit for the completion of a Surveillance Requirement when equipment is removed from service. In this case, the allowable outage time limits of the ACTION requirements are anplicable when this limit expires if the surveillance has not been completed. When a shutdown is required to comply with ACTION requirements, the plant may have entered a H00E in which a new specification becomes appilcable. In this case, the time limits of the ACTION requirements would apply from the time that the new specification becomes appitcable if the requirements of the Limiting Condition for Operation are not met.

Specif.ication 3.0.2 establishes that noncompliance with a specification exists when the requirements of the Limiting Condition for Operation are not met and the associated ACTION requirements have not been implemented within the specified time interval. The purpose of this specification is to clarify that (1) implementation of the ACTION requirements within the specified time interval constitutes compliance with a specification and (2) completion of the remedial measures of the ACTION requirements is not required when compliance with a 1.imiting Condition for Operation is restored within the time interval specified in the associated ACTION requirements.

Specification 3.0.3 establishes the shutdown ACTION requirements that must be implemented when a Limiting Condition for Operation is not met and the condition is not specifically addressed by the associated ACTION requirements. The purpose of this specification is to delineate the time limits for placing the unit in a safe shutdown HODE when plant operation cannot be maintained within the limits for safe operation defined by the Limiting Conditions for Operation and its ACTION requirements. It is not intended to be used as an operational convenience which permits (routine) voluntary removal of redundant systems or components from service in lieu of other alternatives that would not result in redundant systems or components being inoperable. One hour is allowed to prepare for an orderly shutdown before initiating a change in plant operation. This time permits the operator to coordinate the reduction in electrical generation with the load dispatcher to ensure the stability and availability of the electrical grid.

The time limits specified to reach lower H0 DES of operation permit the shutdown to proceed in a controlled and orderly manner that is well within the specitled maximum cooldown rate and with'n the cooldown capabilities of the facility assuming only the minimum required equipment is OPERABLE. This reduces thermal stresses on components of thi primary coolant system and the potential for a plant upset that could challeige safety systems under conditions for which this specification applivs.

l H00E, is not reduced. For example, if HOT STANOBY is reached in 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, the

~

i return to P0HER operation, a penalty is not incurred by having to reach a ,

S lower H00E of operation in less than the total time allowed.  ;

I The saMe principle applies with regard to the allowable outage time limits of '

the ACTION requirements, if compliance with the ACTION requirements for one i specification results in entry into a H00E or condition of operation for l 1 another specification in which the requirements of the Limiting Condition for i j Operation are not met. If the new specification becomes applicable in less i J

time than specified, the difference may be added to the allowable outage time '

1 limits of the second specification. However, the allowable outage time limits of ACTION requirements for a higher HODE of operation may not be used to extend the allowable outage time that is applicable when a Limiting Condition for Operation is not met in a lowcr H00E of operation.

The shutdown requirements of Specification 3.0.3 do not apply when the reactor is in the COLD SHUTDOHN, REFUELING SHUTDOHN, or REFUELING OPERATION operational mode, becaute the ACTION requirements of individual specifications define the remedial measures to be taken.

Limiting Conditions For Operation Bain (Continued)

Specification _3A4 establishes limitations on H00E changes when a Limiting Condition for Operation is not met. It precludes placing the facility in a higher H00E of operation when the requirements for a Limiting Condition for Operation are not met and continued noncompliance te these conditions would result in a shutdown to comply with the ACTION requirements if a change in HODES was permitted. The purpose of this specification is to ensure that facility operation is not initiated or that higher HOMS of operation are not entered when corrective action is being taken to obtain compliance with a specification by restoring equipment to OPERABLE status or parameters to specified limits. Compliance with ACTION requirements that permit continued operation of the facility for an unlimited period of time provides an acceptable level of safety for continued operation without regard to the status of the plant before or af ter a HODE change. Therefore, in this case, entry into an OPERATIONAL H00E or other specified condition may be made in accordance with the provisions of the ACTION requirements. The provisions of this specification should not, however, be interpreted as endorsing the failure to exercise good practice in restoring systems or components to OPERABLE status before plant startup.

The poten - , 'vity insertion due to the moderator pressure coefficient that coult '

om depressurizing the coolant from 2185 psis to saturatic 'n '

of 885 psia is approximately 0.1 percent Ak/k.

During physi .ests, special operating precautions will be taken. In addition, the strong negative Doppler coefficient (1) and the small integrated Ak/k would limit the magnitude of a power excursion resulting from a reduction of moderator density.

The requirement that the reactor is not to be made critical below DTT + 10'F provides increased assurances that the proper relationship between primary coolant pressure and temperatures will be maintained relative to the NDTT of che primary coolant system. Heatup to this temperature will be accomplished by operating the reactor coolant pumps. The DTT at Beginning of Life (BOL) for the most limiting component in the reactor coolant system is less than  ;

+100'F. l l

If the shutdown margin required by Specification 3.5.2 is maintained, there i is no possibility of an accidental criticality as a result of a decrease of coolant pressure.

The requirement for pressurizer bubble formation and specified water level when the reactor is less than 1 percent subcritical will assure that the reactor coolant system cannot become solid in the event of a rod withdrawal accident or a start-up accident and that the water level is above the minimum detectable level.

The requirement that the safety rod groups be fully withdrawn before criticality ensures shutdown capability during startup. This does not prohibit rod latch confirmation, i.e., withdrawal by group to a maximum of 3 inches withdrawn of all seven groups prior to safety rod withdrawal.

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Limiting Conditions for Operation Bufti (Continued)

Concentration of boron in the concentrated boric acid storage tank may be higher than the concentration which would crystallize at ambient conditions.

For this reason and to ensure that a flow of boric acid is available when needed, this tank and its associated piping will be kept above 70*F (30'F above the crystallization temperature for the concentration present). Nnce in the high pressure injection system, the concentrate is sufficiently well mixed and diluted so that normal system temperatures ensure boric acid solubility. The value of 70*F is significantly above the temperature for a solution containing 12,200 ppm boron.(5) crystallization The Low Temperature Overpressure Protection (LTOP) System consists of both an active and a passive subsystem. The active subsystem utilizes the Electro-Matic Operated Valve (EMOV) which provides overpressure protection during normal plant operation. The EMOV actuation circuitry has been modified to provide a second setpoint (500 psig) that is used during low-temperature operations. The low setpoint is manually enabled at 350'F by positioning a key-operated switch in the reactor Control Room. An alarm will sound in the reactor Control Room if the reactor coolant pressure falls below 450 psig and the key-operated switch is not selected for low-tenperature operation. After selection of low temperature operation, additional alarms will occur if power is not removed from each HPI pump; if either Seal l Injection flow is greater than 42 gpm or makeup flow is greater than 135 gpm; if HPI valves are not closed; and if the EMOV block valve HV-21505 is not open. The passive subsystem is based on the plant design and operating philosophy that precludes the plant from being in a water solid condition (except for system hydrotests).

Injection line filling and venting is accomplished without an energized Hakeup or High Pressure Injection pump. Nitrogen overpressure in the Makeup tank provides the motive force for fluid flow during this evolution. This nitrogen overpressure is limited procedurally to 30 psig, and mechanically to 100 psig by the relief valve on the Makeup tank. This pressure clearly does not approach the EMOV low setpoint.

The exception to core flood discharge valves being closed and their motor operator deenergized is based on the Core Flood Tank pressure being reduced to less than the EMOV low setpoint of 500 psig. Hithout the potential for i RCS overpressurization, the valve need not be administrative 1y required to be closed. This provides for other surveillanco testing and maintenance on the Core Flood System.

Two high pressure injection pumps and two decay heat removal pumps are specified. However, only one of each is necessary to supply emergency coolant to the reactor in the event of a loss-of-coolant accident. Both core flooding tanks are required the core.l 4}da single core flood tank has insufficient inventory to reflood The borated water storage tank is used for two purposes:

A. As a supply of borated water for accident conditions.

B. As a supply of borated water for flooding the fuel transfer canal during refueling operation.(2) 390,000 gallons of borated water are supplied for emergency core cooling and Reactor Building spray in the event of a loss of core coolant accident.

This amount fulfills requirements for emergency core cooling. The borated 1

water storage tank minimum volume of 390,000 gallons is based on refueling volume requirements. Heaters maintain the borated water supply at a temperature to prevent freezing. The boron concentration is set at the amount of boron required to maintain the core 1 percent subcritical at 70*F without any control rods in the core. This concentration is 1585 ppm boron while the minimum value specified in the tanks is 1,800 ppm boron.

The requirement that one BWST isolation valve shall be open assures a static head to the injection pump not lined up to the makeup tank.

The post accident Reactor Building cooling may be accomplished by two spray units or by a combination of two emerge :cy cooling units and one spray unit. The specified requirements assure that the required post accident components are available.

The spray system utilizes common suction lines with the decay heat removal system. If a single train of equipment is removed from either system, the other train must be assured to be operable in each system.

Each reactor protection channel key operated shutdown bypass switch is provided with alarm and lights to indicate when the shutdown bypass switch is being used. There are four shutdown bypass keys in the control room under the administrative control of the shift supervisor. The keys will not be used during reactor power operation.

There are fcur reactor protection channels. Normal trip logic is two out of four. Required trip logic for the power range instrumentation channels is two out of three. The EFIC trip logic is two times one-out-of-two taken twice. Minimum trip logic on other instrumentation channels is one out of two.

The EFIC system is designed to automatically initiate AFH when:

1. all four RC pumps are tripped,
2. RPS has tripped the reactor on anticipatory trip indicating loss of main feedwater,
3. the level of either steam generator is low,
4. either steam generator pressure is low, or
5. SFAS ECCS actuation (high RB pressure or low RCS pressure).

The EFIC system will isolate mqin feedwater to any steam generator when the pressure goes below 600 psig.(') l The EFIC system is also designed to isolate or feed AFH according to the following logic:

If both SGs are above 600 psig, supply AFH to both SGs

- If one SG is below 600 psig, supply AFH to the other SG

- If both SGs are below 600 ps thetwoSGsexceeds100psid{g)butthepressuredifferencebetween I

At cold shutdown conditions all EFIC initiate and isolate functions are manually or automatically bypassed. When pressure in both steam generators is greater than 750 psig, the following bypassed initiation signals will have been automatically reset: 1) Loss of 4 RC pumps, 2) low steam generator pressure, 3) low steam generator level.

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Limiting Conditions for Operation The rod position limits are based on the most limiting of the following three criteria: ECCS power peaking, shutdown margin, and potential ejected rod worth. Therefore, compliance with the ECCS power peaking criterion is ensured by the rod position limits. The minimum available rod worth, consistent with the rod position limits, provides for achieving hot shutdown by reactor trip at in any the time, assuming full out position.the(highest

1) The worth controllimits rod position rod that is ensure also withdrawn thatremains inserted rod groups will not contain single rod worths greater than 0.65%

ok/k at rated power. These values have been sh9wn to be safe by the safety analysis of hypothetical rod ejection accident.s2) A maximum single inserted control rod worth of 1.0% ak/k is allowed by the rod position limits at hot zero power. A single inserted control rod worth of 1.0% ok/k at beginning-of-life, hot zero power would result in a lower transient peak thermal power and, therefore, less severe environmental consequences than an 0.65% ak/k ejected rod worth at rated power.

Control rod groups are withdrawn in numerical sequence beginning with Group

1. Groups 5, 6 and 7 are overlapped 25 percent. The normal position at power is for Group 7 to be partially inserted.

The Quadrant Power Tilt limits set forth in Specification 3.5.2.4 have been established to prevent the linear heat rate peaking increase associated with a positive quadrant power tilt during normal power operation from exceeding 7.36%. The limits in Specification 3.5.2.4 are measurement system independent. The actual operating limits, with the appropriate allowance for observability and instrumentation errors, for each measurement system are defined in the station operating procedures.

The Quadrant Tilt and axial imbalance monitoring in Specifications 3.5.2.4F and 3.5.2.6, respectively, normally will be parformed in the process computer. The two-hour frequency for monitoring these qualities will provide ,

adequate surveillance when the computer is out of service.

Allowance is provided for withdrawal limits and reactor power imbalance limits to be exceeded for a period of two hours without specification violation.

Acceptable rod positions and imbalance must be achieved within the two-hour time period or appropriate action such as a reduction of power taken.

Operating restrictions are included in Technical Specifications 3.5.2.50.1 and 3.5.2.50.2 to prevent excessive power peaking by transient xenon. The xenon reactivity must either be beyond the "undershoot" region and asymptotically approaching its equilibrium value at rated power or the reactor must be operated in the range of 87% to 92% of the maximum allowable power for a period exceeding two hours in the soluble poison control mode so that the transient peak is burned out at a lower power level.

Apolicability At all times Action

a. When the Reactor Coolant System activity reaches the limit of Specification 3.1.4, sample the on line waste gas decay tank daily to ensure that the 135,000 curie equivalent Xe-133 limit is not exceeded.
b. With the quantity of radioactive material in any waste gas decay tank exceeding the above limit, immediately suspend all additions of radioactive material to the tank and within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> reduce the tank contents to within the limit, and describe the events leading to this condition in the next Semlannual Radioactive Effluent Release Report oursuant to Specification 6.9.2.3.

Balti Restricting the quantity of radioactivity contained in each waste gas decay tank provides assurance that in the event of an uncontrolled release of the tanks contents, the resulting total body exposure to an individual at the exclusion area boundary (see Figure 5.1-1) will not exceed 500 mrem. This is consistent with Standard Review Plan 15.7.1, "Haste Gas System Failure."

Potential atmospheric releases from a waste gas decay tank are evaluated l assuming design coolant activities (see page 140-25 Vol. VIII USAR). Based on l primary coolant activity as shown in USAR Table 140-7, the decay tank is l assumed to hold the activity associated with the off-gas from one Reactor '

Coolant System degassing with no credit taken for decay.

Calculation of the limiting decay tank activity based on the coolant activity limit of Technical Specification 3.1.4 yields a maximum decay tank inventory of 98,414 curies (Ref. USAR Tablo 140-23). In order for the decay tank l inventory to reach the limiting condition for operation, coolant activity would have to exceed the Technical Specification 3.1.4 limit on coolant activity and this would require a reactor shutdown, thus pr9 venting a further increase in gaseous activity.

Therefore, it is conservative to require that the online waste gas decay tank be sampled _ daily upon reaching the Reactor Coolant System limiting activity value (43/E) to ensure the 135,000 curies equivalent Xe-133 is not eveeeded.

Once the coolant is below the limiting activity, there is no requirement to sample waste gas decay tanks except for discharging.

With one or more required meteorological monitoring channels inoperable for more than 7 days, prepare and submit a Special Report to the Connission pursuant to Specification 6.9.5 within the next 10 days outlining the cause of the malfunction and the plans for restoring the channel (s) to OPERABLE status and include a description of the event in the next Semiannual Radioactivo Effluent Release Report. l 1 ELLt1 i

The OPERABILITY of the meteorological instrumentation ensures that sufficient meteorological data is available for estimating potential radiation doses to the public as a result of routine or accidental release i of radioactive materials to the atmosphere. This capability is required to  ;

evaluate the need for initiating protective measures to protect the health and safety of the public.  ;

Delta Temperature is obtained from calculated differences between measured

! air temperatures at 60 meters and 10 meters. With one or more air temperature monitoring channels inoperable for determining delta temperature, the standard deviation of wind direction (sigma theta) can be used to determine stability classifications.

There is only one meteorological monitoring instrument channel associated

with each parameter shown on Table 3.29-1. Each channel has two instruments (primary and secondary) associated with it. The primary and secondary instruments use common equipment for signal processing.

"Surveillance requirements are raquirements relating to test, calibration, or inspection to ensure that the necessary quality t of systems and components is maintained, that facility operation f will be within safety limits, and that the limiting conditions of

] operation will be met."

i Soecification 4.0.1 establishes the requirement that surveillanen must be l performed during the OPERATIONAL HODES or other conditions for which the  ;

requirements of the Limiting Conditions for Operation apply unless otherwise stated in an individual Surveillance Requirement. The purpose of this j '

! specification is to ensure that surveillances are performed to verify the '

) operational status of systems and components and that parameters are within specified limits to ensure safe operation of the facility when the plant is in a PODE or other specified condition for which the associated Limiting

Conditions for Operation are applicable. Surveillance Requirements do not 4 have to be performed when the facility is in an OPERATIONAL H00E for which the requirements of the associated Limiting Condition for Operation do not apply unless otherwise specified. The Surveillance Requirements associated l with a Special Test Exception are only applicable when the Special Test Exception is used as an allowable exception to the requirements of a specification. ,

Soecification 4JL2 establishes the failure to perform a Surveillance ,

Requirement within the allowed surveillance interval, defined by the  :

Specification 3.0.3), a 24-hour allowance is provided to permit a delay in implementing the ACTIOd requirements. This provides an adequate time limit to complete Surveillance Requirements that have not been performed. The purpose of this allowanco is to permit the completion of a surveillance Lefore a shutdown is required to comply with ACTION requirements or before other remedial measures would be required that may preclude completion of a surveillance. The basis for this allowance includes consideration for plant conditions, adequate planning, availability of personnel, the time required to perform the surveillance, and the safety significance of the delay in complating the required surveillance. This provision also provides a time limit for the completion of Surveillance Requirements that becoce applicable as a consequence of H00E change imposed by ACTION requirements and for completing Surveillance Requirements that are applicable when an exception to the requirements of Specification 4.0.3 is allowed. If a surveillance is not completed within the 24-hour allowance, the time limits of the ACTION requirements are applicable at that time. When a surveillance i. performed within the 24-hour allowance and the Surveillance Requirem:ots are not met, the time limits of the ACTION requiremente are applicable at the time the surveillance is terminated.

Surveillance Requirements do not have to be performed on inoperable i

equipment because the ACTION requirements define the remedial measures that apply. However, the Surveillance Requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABLE status.

SpAcification 4.0 3 establishes that all applicable surveillances must be met before entry into an OPERATIONAL H00E or other condition of operation specified in the Applicability statement. The purpose of this specification is to ensure that system and component OPERABILITY requirements or parameter i limits are mat before entry into a H0DE or condition for which these systems and components ensure safe operation of the facility.

! Irradiation surveillance provides the capability of deto mining the radiation-induced changes in the mechanical and impact properties in the region of the reactor vessel surrounding the core. Test specimens of base metal, deposited weld metal and the heat-affected zone are installed in capsule assemblies placed inside the vessel. In accordance with the schedules of Table 4.2-1, specimens will be removed and a series of drop weight tests, Charpy impact tests and tension tests will be conducted.

Threshold neutron flux detectors and maximum temperature detectors will be installed with the specimens. Changes in nil ductility transition

  • temperature will be determined, and appropriate alteration to plant operating parameters will be made.

l To assure the availability of adequate surveillance data for the Rancho Seco 4 No. I reactor vessel, a program has been developed to monitor the irradiation of the surveillance specimen capsules at the Davis Besse No. 1 ,

reactor and compare this to the irradiation of the Rancho Seco No I reactor i

vessel. Fluence estimates which are conservative in the appropriate

, direction are used for this comparison. The frequency of monitoring varies

depending on the known neutron fluence lead factor between the capsules and the reactor vessel. This provides ample time for anticipating problems and j initiating corrective action should operation of the host reactor be seriously delayed. For the purpose of Technical Specification 4.2.1.2, the l i definition of Regulatory Guide 1.16, Revision 4 (August 1975) applies for the term ' commercial operation'.

Prior to initial operation, the l containment will be strength tested at 115 percent of design pressure. The containment will also be leak tested prior to initial operation at Pp and l Pt (52 psig and 26 psig, respectively). These tests will verify that the l leakage rate from Reactor Building pressur relationshipsgiveninthespecification.jptipnsatisfiesthe s i n2i The performance of a periodic integrated leakage rate test during plant life provides a current assessment of potential leakage from the containment in case of an accident that would pressurize the interior of the containment.

The minimum of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> was specified for the integrated leakage rate test l to help stabilize conditions and thus improve accuracy and to better evaluate data scatter. The frequency of the periodic integrated leakage rate test is keyed to the refueling schedule for the reactor, because these tests can best be performed during refueling shutdowns.

Proposed Amendment No. 76, 171 4-19 l

e RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Surveillance Standards j l

The specified frequency of periodic integrated leakage rate tests is based on threemajorconsiderations. First is the low probability of leaks in the liner because of conformance of the complete containment to a 0.10 percent leakage rate at 52 psig during pre-operational testing and the absence of any ,

significant stresses in the liner during reactor operation. Second is the  ;

more frequent testing at 52 psig of those portions of the containment envelope that are most likely to develop leaks during reactor operation (penetrations ,

and isolation valves) and the low value 0.06 percent of leakage that is j specificed as acceptable from penetrations and isolation valves. Third is the '

tendon stress surveillance program which provides assurance that an important part of the structural integrity of the containment is maintained. ,

I Hore frequent testing of various penetrations is specified as these locations  !

are more susceptible to leakage than the Reactor Building liner due to the l mechanical closure involved. Particular attention is given to testing those l penetrations with resilient sealing materials, penetrations that vent directly j to the Reactor Building atmosphere, and penetrations that connect to the Reactor Coolant System pressure boundary. The basis for the specification of a total leakage rate of 0.075 percent from penetrations and isolation valves l

is that approximately three quarters of the allowable integrated leakage rate should be from those sources, in order to provide assurance that the integrated leakage rate would remain within the specified limits during the inter"ais between integrated leakage rate tests. Valve operability tests are I specified to assure proper closure or opening of the Reactor Building isolation valves to provide for isolation of functioning of safety features ,

systems. Valves will be stroked to the position required to fulfill their j safety function unless it is established that such testing is not practical '

during operations.

The airlock seals are tested at 10 psig because that is the manufacturer's recommended pressure for reverse flow through the seals. The extrapolation formula is derived assuming laminar, incompressible flow and provides conservative leak rates.

This specification complies with Appendix J to 10 CFR 50 as published in the 1 Federal Register on February 14, 1973, with the exemptions to Appendix J l granted July 13, 1977.

EA111 l The emergency core cooling systems are the principal reactor safeguards in  !

l the event of a loss-of-coolant accident. The removal of heat from the core  !

provided by these systems is designed to limit core damage. '

The decay heat removal pumps are tested singularly for operability by opening the bonted water storage tank outlet valves and the test line valves to the borated water storage tank. This allows water to be pumped from the borated water storage tank through each of the injection lines and back to the tank through a test line.

With the reactor shut down, the check valves in each core flooding line are checked for operability by reducing the reactor coolant system pressure until the indicated level in the core flood tanks verify the check valves have opened.

BAH 1 The leakage rate limit for the Decay Heat Removal System is a judgment value based on assuring that the components can be expected to operate without

. mechanical failure for a period on the order of 200 days after a LOCA. The test pressures achieved eithat by normal system operation or by hydrostati-cally testing give an adequate margin over the highest pressure within the

! system after a design basis accident. Similarly, the pressure tests for i the return lines from the containment to the Decay Heat Removal Sy tem are equivalent to the peak calculated pressure after a LOCA. A Decay Heat  !

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Surveillance Standards 4.9 REACTIVITY ANOMALIES 6pp1_icability I Applies to potential reactivity anomalies. l Objective To require the evaluation of reactivity anomalies of a specified magnitude occurring during the operation of the unit.

Soecification l Following a normalization of the computed boron concentration as a function ,

of burnup, the actual boron concentration of the coolant shall be compared monthly with the predicted value. If the difference between the observed and predicted steady-state concentrations reaches the equivalent of l 1 percent in reactivity, an evaluation will be made to determine the cause of the discrepancy and reported to the Nuclear Regulatory Commission.  !

EM To eliminate possible errors in the calculations of the initial reactivity i of the core and the reactivity depletion rate, the predicted relation i between fuel burnup and the boron concentration, necessary to maintain l adequate control characteristics, must be adjusted (normalized) to )

accurately reflect actual core conditions. When full power is reached initially, and with the control rod groups in the desired positions, the boron concentration is measured and the predicted curve is adjusted to this point. As power operation proceeds, the measured boron concentration is compared with the predicted concentration and the slope of the curve relating burnup and reactivity is compared with that predicted. This process of normalization should be completed after about 10 percent of the total core burnup. Thereafter, actual boron concentration can be compared with prediction, and the reactivity status of the core can be continuously evaluated. Any reactivity anomaly greater than 1 percent would be I

I unexpected, and its occurrence would be thoroughly investigated and evaluated.

The value of 1 percent is considered a safe limit since a shutdown margin of at least 1 percent with the most reactive rod in the fully withdrawn I position is always maintained. I i

Reason: Typographical corrections. The correction to the ASME title provides its proper designation. The referenced FSAR paragraphs were changed to USAR in Proposed Amendment No. 139 (1/29/86). Further review has determined that paragraph 4.4.4 as shown for Reference (5) is nonexistent in the USAR and is therefore deleted. References (6) and (7) are renumbered accordingly.

28. Change _DescrJptbn: Specification 3.1.3 Bases, pages 3-6 and 3-7:

Delete "open and tagged" and "racked out" and add "remove power" or "power removed from."

Renoo: Hording is not consistent. "Removing power" is consistent with wording in Standard Tech Specs.

32. Change Descriotion: Specification 3.3 Bases, page 3-22: Delete subparagraph (a).

Reason: Subparagraph (a) states "Motor operated valves shall be placed in the closed position and power supplies de-energized." In reviewing the previous amendments affecting this Bases, there is no accounting for the appearance of this subparagraph. Since the wording is irrelevant to the borated water storage tank being discussed, the District proposes to delete subparagraph (a).

33. Changelestdp. tion: Specifications 3.4.1 and 3.4.2, pages 3-23 and 3-23a: Add "through HOT SHUTDOHN" to 3.4.1. Delete "critical" and add "in the STARTUP through POWER OPERATION mode" to 3.4.2.

Bea1on: The applicability of 3.4.1 and 3.4.2 was not clearly stated.

The intent clearly is that these specifications are applicable for the range of plant conditions now specified.

Reason: Note (1) was added for clarification and is in accord with the actual EFIC design as described in Proposed Amendment Nr. 152, approved as Amendment No. 93 (1/5/88). Changing the differential pressure unit to psid is an editorial correction.

36. ChangeJ)eicdotlon: Specification 3.5.2.2, page 3-31: 'Jelete letter "A." from subheading.

Reason: Unnecessary since there are no comparable succeeding lettered items.

37. Change _Desctlption: Specification 3.5.2.2, page 3-32: Change subheading letter "F" to "e."

Reason: Page 3-31 was retilsed by Amendment No. 97 and lettering on page 3-32 does not agree.

i Reason: Note (1) was added for clarification and is in accord with the actual EFIC design as described in Proposed Amendment No. 152, approved as Amendment No. 93 (1/5/88). Changing the differential pressure unit from "100 psig" to "100 psid" is an editorial correction.

42. Change

Description:

Specification 3.9 Bases, page 3-46b: Replace the reference to a specific operating procedure with the words "as required by operating procedures." 4 Reason: Replacement of the wording "per Operating Procedure A.21, l Section 7.3" with less specific wording allows future renumbering of the procedure or the section without necessitating a Technical Specification amendment. ,

Reason: In reviewing the USAR, it was determined that the contents of page 140-25 of Volume VIII are eruivalent to page 140-25 of Volume VI of the FSAR. The changes from "FSAR" to "USAR" are as explained for Change Description No. 14. Spelling out "curies" is consistent with other uses of the unit in Specification 3.20.

Reason: 4.0.1 through 4.0.3 were added by Amendment No. 97 without any Bases. Bases are from Generic Letter 87-09.

1 53. Change _Q11CIlption: Specification 4.1 Bases, page 4-2: Add the word "are" to first line of second paragraph; add reference to the heat balance calibration requirement when Nuclear Instrumentation indicated power is 10*l,or more above core thermal power.

Reason: Editorial clarification. Amendment No. 78 appropriately changed the Bases to address the 101. calibration requirement. Amendment No. 87 inadvertently changed the Bases for Calibration back to the pre-Amendment No. 78 version. The Calibration Bases as approved in Amendment No. 78 is placed back into the Tech Specs.

, 54. Change _DestdpilDD: Table 4.1 ), Item 29, page 4-7: Add the wording "Equivalent to Item 49, but excludes SPDS" to the Remarks column.

55. Change _01stdption: Table 4.1-1, Item 39, page 4-7a: Add calibration per refueling interval for control rod relative position.

Reason: Control rod absolute and relative positions are checked, one compared to the other, once per shif t. Since the control rod absolute

. position is calibrated each refueling interval, it is appropriate for control rod relative position to be calibrated at the same time.

Description:

Table 4.1-1, page 4-7b: Delete Item 45, Emergency plant radiation instruments.

Reason: Item 45. Emergency plant radiation instruments, was deleted because this equipment (hand-held radiation meters) does not fall under the applicability of Specification 4.1, which states: ,

"Applies to items directly related to safety limits and limiting conditions for operation during power operation. During cold shutdown, systems and components required to maintain safe shutdown will be tested."

57. Change _Ducriotion: Table 4.1-1, page 4-7b: Hove 44.c to 46.b. Item 44.d is relabeled 44.c.

Reason: The results of design engineering calculations indicate that these EFIC pressure transmitters, located outside of containment, require annual calibration rather than on a refueling interval as specified for the remainder of each of these channels.

60. Change _0_eist.ipilon: Table 4.1-1, page 4-79: Change the Channel Description of Item 85 from "Hide Range OSTG Pressure Pressurizer Level" to "Hide Range OTSG Pressure." Insert new Item 86 with the Channel Description "Pressurizer Level," and renumber existing Items 87 through
90. The Check, Test and Calibrate notations are the same for both Item 85 and 86.

Reassa: Combining the two Channel Description items was a typographical error.

61. Change _ Duct _lplion: Specification 4.2.2 Bases, page 4-12: In second paragraph, change "4.2.8" to "4.2.1.2."

Reason: For editorial purposes, Specification 4.2.8 was moved to Specification 4.2.1 by Amendment No. 76 (9/30/85). Through oversight, the corresponding number change was not made in the Bases, and is herein proposed for correction.

62. Change _Descdption: Specification 4.4.1.1.5, page 4-16a: Add specific  !

. Benon: Only an inspection prior to an integrated leak rate test and not an annual inspection of the containment surfaces is required by 10 CFR 50, App. J Section V.A. The change in test terminology is editorial, and addition of the special report reference is for I clarification. The Bases statement that periodic tests are to be performed without preliminary leak detection surveys or leak repairs, etc., is deleted as an option allowed by IE Notice 85-71, and 10 CFR 50,

Appendix J. The remaining deleted sentences from the Bases concern
reduced pressure testing, an option which is not performed at Rancho Seco.

1 Specifications 4.4.2.6, 4.4.2.6.2, 4.4.2.6.3 and 4.4.2.6.4.

Realon: Reporting responsibilities are established by administrative procedures, and thus need not be made a Technical Specification requirement. The number 6.9-1 is an incorrect designation for a l specification. Specification 6.9.1 Jiscusses general reporting requirements. Specification 6.9.5B is specific to the type of report being discussed in Specification 4.4.2.5. The Liner Plate Surveillance specified in 4.4.2.6, 4.4.2.6.2, 4.4.2.6.3 and 4.4.2.6.4 was only required af ter the first year of initial operation and is no longer applicable.

.- Facility Change Safety Analysis Log No. 1076 Prv osed Amendment No. 171 Page 13 of 13 NO SIGNIFICANT HAZARDS CONSIDERATION The proposed changes have been evaluated by the District using the standards of 10 CFR 50.92. The conclusion has been reached that the changes constitute no significant hazard to the public. The following is the basis for the District's conclusion:

The changes are purely administrative, consisting of editorial corrections, renumbering and relocating of specifications, updating references to codes and standards, and specification clarifications. The proposed administrative changes have been judged to not constitute a significant hazards consideration because the changes:

a. Would not involve a significant increase in the probability or >

consequences of an accident previously evaluated since the proposed -

administrative changes do not affect existing plant designs or cause )

changes to existing plant operations.  !

b. Would not create the possibility of a new or different kind of  !

accident from any accident previously evaluated since the proposed administrative changes do not introduce any new operational requirements that could affect plant safety, i

c. Would not involve a significant reduction in the margin of safety l since the purely administrative changes could not cause a reduction in i the conservative nature of the Technical Specifications due to the editorial nature of the proposed changes.  ;
