a TS.2.1-2 REV The solid curves of Figure TS 2.1-1 represent the loci of points of tnermal power, ccalant pressure, and coolant average temperature for which either the coolant enthalpy at the core exit is limiting or the DNB ratio is limiting. For the 1685 psig and 1985 psig curves, the coola~nt average enthalpy at the core exit is equal to saturated water enthalpy below power levels of 81% and 65% respectively. For the 2235 psig and 2385 psig curves, l the coolant average temperature at the core exit is equal to 650*F below power levels of 58% and 66% respectively. For all four curves, the DNBR l is equal to 1.3 at higher power levels. The area of safe operation is below these curves.

The plant conditions required to violate the limits in the lower power range are precluded by the salt'-actuated safety valves on the steam generators.

The highest nominal setting of the steam generator safety valves is 1129 psig (saturation temperature 560*F). At zero power the difference between primary coolant and secondary coolant is zero and at full power it is 50*F. The reactor conditions at which steam generator safety valves open is shown as a dashed line on Figure TS.2.1-1.

Except'for special tests, power operation with only one loop or with natural circulation is not allowed. Safety limits for such special tests will be determined as a part of the test procedure. <

The curves are based on the following nuclear hot channel factors ( ):

F H = 1.65 [1 + 0.2(1-P)]; and F = 2.32 This combination of hot channel factors is higher than that calculated at full power for the range from all control rods fully withdrawn to maximum allowable control rod insertion. The control rod insertion limits. are covered by Specification 3.10. Adveric power distribution factors could occur at lower power levels because additional control rods are in the core.

However, the control rod insertion limits specified by Figure TS.3.10-1 assure that the DNB ratio is always greater at part power thar; at full power.

4. If a reactor is at or above cold shutdown:

(a) With the specific activity of the primary coolant greater than 1.0 microcurie per gram DOSE EQUIVALENT I-131 or greater than 100/E nicrocuries per gram, perform the sampling and analysis require-ments of item 4a of Table 4.1-2B until the specific act i vity of the primary coolant is restored to within its limits. A special report shall be submitted to the Commission within 30 days. This report shall contain the results of the specific activity analyses together with the following information:

1. Reactor power history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to the first sample in which the limit was exceeded,
2. Fuel burnup by core region,
3. Clean-up flow history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to the first sample in which the limit was exceeded,

5. The time duration when the specific activity of the primary coolant exceeded 1.0 microcurie per gram DOSE EQUIVALENT I-131.

. BASES The limitations on the specific activity of the primary coolant ensure that tha resulting 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> doses at the site boundary will not exceed an ,

appropriately small fraction of Part 100 limits following a steam generator tube rupture accident in conjunction with an assumed steady state primary-to-secondary steam generator leakage rate of 1.0 GPM. The values for the limits I on specific activity represent limits based upon a parametric evaluation by the NRC of typical site locations. These values are conservative ln that specific site parameters of the Prairie Island site, such as site boundary location and meteorological conditions, were not considered in this evaluation.

Specification 3.1.E.2, permitting power operation to continue for limited l time periods with the prir.ary coolant's specific activity greater than 1.0 microcuries/ gram DOSE EQUIVALENT I-131, but within the allowable limit shown on Figure TS.3.1-5, accommodates possible iodine spiking phenomenon l" which may occur following changes in thermal power. Operation with specific activity levels exetding 1.0 microcuries/ gram DOSE EQUIVALENT I-131 but within the limits shown on Figure TS.3.1-5 must be restricted to no more than 800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> per year (approximately 10 percent of the unit's yearly operating time) since the activity levele allowed by i

Effectively, the baron concentration must be maintainted at a predicted concentration which shall have the reactor initially suberitical by at least 10% AK/K if the containment system is to be disabled with the vessel open.

The 2 psig limit on internal pressure provides adequate margin between themaximuminternalpressureof46psigandthepeak29ecident pressure resulting from the postulated Design Basis Accident.

The containment vessel is designed for 0.8 psi internal vacuum, the occurrence of which will be prevented by redundant vacuum breaker systems.

The calculated period following LOCA for which the shield building annulus pressure is positive, and the calculated off-site doses are sensitive to this initial air temperature difference.

The specified 44 k6femperature difference is consistent with the LOCA accident analysis The initial testing of inleakage into the shield building and the auxiliary building special ventilation zone (ABSVZ) has resulted in greater specified inleakage (Figure TS 4.4-1, change No. 1) and the necessity to deenergize the turbine building exhaust fans in order to achieve a negative pressure in the ABSVZ (TS.3.6.A.10).

2. Radiation levels in fuel handling areas, the containment and the spent fuel storage. pool areas shall be monitored continuously.
3. The core suberitical. neutron flux shall be continuously monitored by at least two neutron monitors, each with continuous visual indication in the control room and one with audible indication in the containnent, which are in service whenever core geometry is being changed. When core geometry is not being changed, at least one neutron flux monitor shall be in service. ,
4. During reactor vessel head removal and while loading and unloading fuel from the reactor, the reactor shall be suberitical by at least 10% AK/K.

The required boron concentration shall be verified by chemical analysis daily.

5. During movement of fuel assemblies or control rods out of the reactor vessel, at least 23 feet of water shall be maintained above the reactor vessel flange. The required water level shall be verified prior to moving fuel assemblies or control rods and at least once every day while the cavity is flooded.
6. At least one residual heat removal pump shall be operable and running.

The pump may be shut down for up to one hour to facilitate movement of l fuel or core components.

7. If the water level above the top of the reactor vessel flange is less than 20 feet, except for control rod unlatching / latching operations or upper internals removal / replacement, both residual heat removal loops shall be operable.
8. If Specification 3.8.A.6 or 3.8.A.7 cannot be satisfied, all fuel handling l operations in containment shall be suspended, the containment, integrity requirements of Specification 3.8. A.1 shall be satisfied, and no reduction in reactor coolant boron concentration shall be made.

TS.3.8-3 REV BASES The equipment and general procedures to be utilized during refueling are discussed in the FSAR. Detailed instructions, the precautions specified above, and the design of the fuel handling equipment incorporating built-in interlocks and safety features, provide assurance that no incident could occur during the refueling 1fPerations that would result in a hazard to public health and safety.' Whenever changes are not being made in core geometry, one flux monitor is sufficient. This permits maintenance of the instrumentation. Continuous monitoring of radiation levels (B. above) and neutron flux provides immediate indication of an unsafe condition. The residual heat removal pump is used to maintain a uniform boron concentration.

The shutdown margin indicated in A.4 above will keep the core subcritical, l even if all control rods were withdrawn from the core. During refueling, the reactor refueling cavity is filled with approximately 275,000 gallons of borated water. The boron concentration of this water is sufficient to maintain the reactor suberitical by approximately 10% LK/K in the cold condition with all rods inserted, and will also maintain the cort 2fub-critical even if no control rods were inserted into the reactor Periodic checks of refueling water -boron concentration insure that proper shutdown margin is maintained. A.9 allows the control room operator to l inform the manipulator operator of any impending unsafe condition detected from the main control board indicators during fuel movement.

TS.3.8-4 REV the cask into a carrier, there is a potential drop of 66 feet (5) . The cask will not be loaded onto the carrier for shipment prior to a 3-month storage period. At this time, the radioactivity has decayed so that a release of ficsion products from all fuel assemblies in the cask would esult in off-site doses less than 10 CFR Part 100. It is assumed, for this dose analysis, that 12 assemblies rupture after storage for 90 days. Other assumptions are the same as those used in the dropped fuel assembly accident in the SER, Section 15.

The resultant doses at the site boundary are 94 Rems to the thyroid and 1 Rem whole body.

The Spe'nt Fuel Pool Special Ventilation System ( is a safeguards system which maintains a negative pressure in the spent fuel enclosure upon detection of

.high area radiation. The Spent Fuel Pool Normal Ventilation system is auto-matically isolated and exhaust air is drawn through filter modules containing a roughing filter, particulate filter, and a charcoal filter before discharge to the environment via one of the Shield Building exhaust stacks. Two completely

-redundant trains are provided. The exhaust fan and filter of each train are shared with the corresponding train of the Containment In-service Purge System.

High efficiency particulate absolute (HEPA) filters are installed before the charcoal adsorbers to prevent clogging of the iodine adsorbers in each SFPSVS filter train. The charcoal adsorbers are installed to reduce the potential release of radioiodine to the environment. The in-place test results should indicate a HEPA filter leakage.of less than 1% through DOP testing and a charcoal adsorber leakage of less than 1% through halogenated hydrocarbon testing. The laboratory carbon sample test results should indicate a radioactive methyl iodide removal efficiency of at least 90% under test conditions which are more severe than accident conditions. The satisfactory completion of these periodic tests combined with the qualification testing conducted on new filters and adsorber provide a high level of assurance that the emergency air treatment systems will perform as predicted in the acciaent analyses. ,

During movement of irradiated fuel assemblies or control rods, a water level of 23 feet is maintained to provide sufficient shielding.

The water level may be lowered to the top of the RCCA drive shafts' for latching and unlatching. The water level may also be lowered below 20 feet for upper internals removal / replacement. The bases for these allowances are (1) the refueling cavity pool has sufficient level to allow time to initiate repairs or emergency procedures to cool the core, (2) during latching / unlatching and upper internals removal / replacement the level is closely monitored because the activity uses this level as a reference point, (3) the time spent at this level is minimal.

The K(Z) function shown in Figure TS.3.10-5 is a normalized function having limits for three regions. The K(Z) specified for the lowest six feet of the core is arbitrarily flat since the lower part of the core is generally not limiting. Above that region, the K(Z) value is based on large and small break LOCA analyses. The K(Z) in the uppermost region is limited to reduce the PCT expected during a small break LOCA since this region of the core is expected to uncover temporarily for some small break LOCAs.

  • +* (~}
  • When a measurement of F AH is taken, experimental error must be allowed for and 4 percent is the appropriate allowance for a' full core map taken with the movable incore detector flux capping system.

Measurements of the hot channel factors are required as part of startup physics bests, at least once each effective full power month of operation, and whenever abnormal power distribution conditions require a reduction

- of core power to.a level based on measured hot channel factors. The incore map taken following initial loading provides confirmation of the basic nuclear design bases including proper fuel loading patterns. The periodic monthly incore mapping provides additional assurance that the nuclear design bases remain inviolate and identify operational anomalies which would otherwise affect these bases.

For normal operation, it is not necessary to measure these quantities. ,

Instead it has been determined that, provided certain conditions are observed, the hot channel factor limits will be net; these conditions are as follows:

1. Control rods in a single bank move together with no individual rod insertion differing by more than 15 J

e b

TS.3.10-11 REV inches from the bank demand position. An accidental misalignment limit of 13 steps precludes a rod misalign-ment greater than 15 inches with consideration of maximum instrumentation error.

2. Control rod banks are sequenced with overlapping banks as described in Technical Specification 3.10. ,
3. The control bank insertion limits are not violated.
4. Axial power distribution control procedures, which are given in terms of flux difference control and control bank insertion limits are observed. Flux difference refers to the difference in signals between the top and bottom halves of two-section excore neutron detectors. The flux difference is a measure of the axial offset which is defined as the difference in normalized power between the top and bottom halves of the core.

The permitted relaxation in F"H and F allows for radial power shapechangeswithrodinsertkontotheinsertionlimits. It has been determined that provided the above conditions 1 through 4 are obsegved, these hot channel factor limits are met. In specification 3.10, F arbitrarily limited for P 10.5 (except forlowpowerphysicstestsh.is The proceduras for axial power distribution control referred to above are designed to minimize the effects of xenon redistribution on the axial power distributicn during load-follow maneuvers. Basically control of flux difference is required to limit the difference between the current value of Flux Difference ( AI) and a reference value which corresponds to the full power equilibrium value of Axial Of fset (Axial Of fset = AI/ fractional power). The reference value of flux difference varies with power level and burnup but expressed as axial "

offset it varies only with burnup.

The technical specifications on power distribution control assure that the Height Dependent Heat Flux Hot Channel Factor upper bound envelope l of Figures TS.3.10-5 times TS.3.10-7 is not exceeded and lenon distri-butions are not developed which at a later time, would cause greater local power peaking even though the flun dif ference is then within the limits specified by the procedure.

The target (or reference) value of flux difference is determined as follows: At any time that equilibrium xenon conditions have been established, the indicated flux difference is noted with the full length rod control rod bank more then 190 steps withdrawn This value, divided by the fraction of full power at which the core was operating is the full power value of the target flux difference.

Values for all other core power levels are obtained by multiplying the full power value by the fractional power. Since the indicated equilibrium was noted, no allowances for excore detector error are necessary and indicated deviation of !5 percent I are permitted from the indicated reference value. Figure TS.3.10-6 shows the allowed deviation from the target flux difference as the function of thermal power.

e TS.3.10-13 REV resulting from operation within the target band. The consequences of being outside the +5% target band but within the Figure TS.3.10-6 limit for power levels between 50% and 90% has been evaluated and determined to result in acceptable peaking factor values. - Therefore, while the l deviation exists the power level is limited to 90 percent or lower depending on the indicated axial flux dif ference. In all cases the

+5 percent target band is the Limiting Conditica for Operation. Only when the target band 'a violated da the limits under Figure TS.3.10-6 apply.

If, for any reason, the indicated axial flux dif ference is not controlled within *.he +5 percent band for as long a period as one hour, then xenon distributions may be significantly changed and operation at 50 percent is required to protect against potentially more severe consequences of some accidents.

As discussed above, the essence of the procedure ic to maintain the xenon distribucion in the core as close to the equilibrium full power condition as possible. This is accomplished by using the boron system to position the full length control rods to produce the required indicated flux difference. .

For Condition II events the core is protected from overpower and a minimum DNBR of 1.30 by an automatic protection system. Compliance with operating procedures is assumed as a precondition for Condition II transients, however, operator error and equipment malfunctions are separately assumed to lead to the cause of the transients considered.

Quadrant Power Tilt Limits Quadrant power tilt limits are based on the following considerations. Fre-quent power tilts are not anticipated during normal operation since this phenomenon is caused 'uy some asymmetric perturbation, e.g. rod misalignment, x-y xenon transient, or inlet temperature mismatch. A dropped or misaligned rod will easily be detected by the Rod Position Indication System or core instrumeatation per Specification 3.10.F. and core limits protected per Specification 3.10.E. A quadrant tilt by some other means (x-y xenon tran-sient, etc.) would not appear instantaneously, but would build up over several hours and the quadrant tilt limits are set to protect against this situation. They also serve as a backup protection against the dropped or misaligned rod.

Operational experience shows that normal power tilts are less than 1.01.

Thus, sufficient time is available to recognize the presence of a tilt and correct the cause before a severe tilt could build up. During start-up and power escalation, however, a large tilt could be initiated.

Therefore, the Technical Specification has been written so as to prevent escalation above 50 percent power if a large tilt is present.

TS.4.13-1 REV 4.13 SNUBBERS Applicability Applies to periodic testing and surveillance requirements of safety related hydraulic snubbers.

0bjective To verify the integrity and operability of hydraulic snubbers.

Specification -

The following surveillance requirements apply to all safety related snabbers. These requirements augment the inspections required by Section XI of the ASME Code.

A. Visual Inspection of snubbers shall be conducted in accordance with.

the following schedule:

No. of Snubbers Found Next Required

' Inoperable per Inspection Period Inspection Period 0 18 months 2 25%

1 12 months ! 25%

2. . 6 months t 25%

3,4 124 days ! 25%

. 5,6,7 . 62 days t 25%

8 or more 31 days t 25%

The required inspection interval shall not be lengthened more than one step at a time.

Snubbers may be categorized in two groups, " accessible" or

" inaccessible" based on their accessibility for inspection during reactor operation. These two groups may be inspected ,

independently according to the above schedule.

B. Visual inspections shall verify (1) that therc are no visiblew indications of damage or impaired operability, (2) attachments to the supporting structure are secure, and (3) in those locations where snabber movement can be manually induced without disconnecting the snubber, that the snubber has freedom of movement and is not frozen up. Snubbers which appear inoperable as a result of visual inspection may be determined Operable for the purpose of, establishing the next visual inspection interval by:

4 a

9

TS. 4.13-2 REV

a. Clearly establishing the cause of the rejection for that particular snubber and for others that may be generically susceptible; and

.b. Functionally testing the affected snubber in the as-found condition and finding it operable per Specification 4.13.D.

However, when the fluid port of a hydraulic suubber is found to be uncovered, the snubber shall be considered inoperable for purposes of establishing the next visual inspection interval. All hydraulic snubbers connected to an inoperable common hydraulic fluid reservoir shall be considered as inoperable snubbers.

C. Except as specified below, functional testing of snubbers shall be l conducted at least once per 18 months during cold shutdown. Ten percent of the total of each type snubber shall be functionally tested either _ in place or in a bench test. For each snubber that does not meet the functional test acceptance criteria in Specifica-tion 4.13.D below, an additional ten percent of that type of snubber shall be functionally tested until no more failures are found or all snubbers of that type have been tested.

The representative sample selected for functional testing shall include the various configurations, operating environments, and the range of size and capacity of the snubbers. Twenty-five l percent of the sample shall include snubbers from the following three categories. ,

a. The first snubber away from a reactor vessel nozzle
b. Snubbers within five feet of heavy equipment (valve, pump, turbine, motor, etc.)
c. Snubbers within ten feet of the discharge of a safety / relief valve Snubbers identified as "High Radiation Area" or " Difficult to l Remove" are exempt from functional testing provided a justifiable

< . basis for exemption is presented for Commission review; snubber life testing is performed to qualify snubber operability for all design conditions;'or snubbers of the same type, configuration, and similar service have been tested for a ten year period and no failures have occurred. In such exempt cases, a qualitative test report shall be on file to substitute for the required functional testing.

In addition to the regular sample and specified re-sampling, snubbers which failed ' the previous functional test shall be re-tested during the next test period. If a spare snubber has.been installed in place of a failcd snubber, then both the failed snubber, if it is repaired and installed in another position, and the spare snubber shall be retested.

TS.4.13-3 REV If any snubber selected for functional testing either fails to lockup or fails to move (i.e. , frozen in place) the cause shall be evaluated and all snubbers subject to the same defect shall be functionally tested. This testing is in addition to the regular sampic and specified re-samples.

D. Hydraulic snubber functional tests shall verify that: ,

a. Activation (restraining action) is achieved within the specified range of velocity or acceleration in both tension and compression.
b. Snubber bleed, or release rate, where required, is within the specified range in compression or tension. For snubbers specifically required to not displace under continuous load, the ability of the snubber to withstand load without disp. lace-ment shall be verified.

E. An engineering evaluation shall be performed for all components supported by inoperable snubbers. The purpose of this engineering evaluation shall be to determine if the components were adversely affected by the inoperable snubber (s) to ensure that the components remain capable of meeting the designed service.

F. The installation and maintenance records for each snubber shall l be reviewed at least once every 18 mcaths to verify that the indicated service life will not be exceeded prior to the next scheduled snubber service life review. If the indicated service life will be exceeded, the snubber service life shall be re-evaluated or the snubber shall be replaced or reconditioned to extend its service life beyond the date of the next scheduled service life review. This re-evaluation, replacement, or recondi-tioning shall be indicated in the records. ,

BASES The visual inspection frequency is based upon maintaining a constant level of snubber protection to systems. Therefore, the required inspection interval varies inversely with the observed snubber failures and is determined ty.the number of inoperable snubbers found during an inspection.

Inspections performed before that interval has elapsed may be used as a new reference point to determine the next inspection. However, the results of such early inspecitons performel before the original required time interval hat- elapsed (nominal time less 25%) may not be used to lengthen the required inspection interval. Any inspection whose results require a shorter inspection interval will override the previous schedule.

b. Each Reportable Event shall be reviewed by the Operations Committee and the results of this review shall be submitted to the Safety Audit Committee and the Vice President Nuclear Generation.

C. Environmental Reports The reports listed below shall be submitted to the Administrator of the appropriate Regional NRC Office or his designate:

1. Annual Radiation Environmental Monitoring Report e .

(a) Annual Radiation Environmental Monitoring Reports covaring the operation.of the program during the previous calendar year shall be submitted prior to May 1 of each year.

(b) The Annual Radiation Environmental Monitoring Reports shall include summaries, interpretations, and an analysis of trends of the results of the radiological environmental surveillance activities for the report period, including a comparison with' preoperational studies, operational controls (as appropriate),

and previous environmental surveillance reports and an assess-ment of the observed impacts of the plant operation on the environment. The reports shall also include the risults of b land use censuses required by Specification 4.10.B.l. If harmful effects or evidence of irreversible damage are detected by the monitoring, the report shall provide an analysis of the problem and a planned course of action to alleviate the problem.

(c) The Annual Radiation Environmental Monitoring Reports shall include summarized and tabulated results in the format of Regulatory Guide 4.8, December 1975 of all radiological environmeatal samples taken during the report period. In the event that some results are not available for inclusion with the report, the report shall be submitted noting and explaining the reasons for the missing results. The missing data shall be submitted as soon.as possible in a supplementary report.

TS.6.7-5

- REV (d) The reports shall also include the following: a summary description of the radiological environmental monitoring program; a map of all sampling locations keyed to a tabla giving distances and directions from one reactor; add the results of licensee participation in the Interlaboratory Comparison Program, required by Specification 4.10.C.l.

2. Environmental Special Reports l (a) When radioactivity levels in samples exceed limits specified in Table 4.10-3, an Environmental Special Report shall be  !

submitted within 30 days from the end of the affected calendar quarter. For certain cases involving long analysis time, determination of quarterly averages may extend beyond the 30 day period. In these cases the potential for exceeding the quarterly limits will be reported within the 30 day period to be followed by the Environmental Special Report as soon as l practicable.

3. Other Environmental Reports (non-radiological, non-acuatic)

Written reports for.the following items shall be submitted to the appropriate NRC Regional Administrator:

~

a. Environmental events that indicate or could result in a signi-ficant environmental impact causually related to plant opera-tion. The following are examples: Excessive bird impaction; onsite plant or animal disease outbreaks; unusual mortality of any species protected by the Endangered Species Act of 1973; or increase in nuisance organisms or conditions. This report shall be submitted within 30 days of the event and shall (a) describe, analyze, and evaluate the event, including extent and nagni-tude of the impact and plant operating characteristics, (b) describe the probable cause of the event, (c) indicate the action taken to correct the reported event, (d) indicate the corrective action taken to preclude repetition of the event and to prevent similar occurrences involving similar components or systems, and (e) indicate the agencies notified and their preliminary responses,
b. Proposed changes, test or experiments which may result in a significant increase in any adverse environmental impact which was not previously reviewed or evaluated in the Final Environ-mental Statement or supplements thereto. This report shall include an evaluation of the environmental impact of the pro-posed activity and shall be submitted 30 days prior to imple-menting the proposed change, test or experiment.

D. Special Reports Unless otherwise indicated, special reports required by the Technical Specification shall be submitted to the appropriate NRC Regional Administration within the time period specified for each report.
