INITIAL APPROACH TO POWER TESTS (8 SERIES STARTUP TESTS)

The initial approach to power is accomplished in a series of discrete power level stages. At each power level, tests are made to measure .

the characteristics of the plant and to ensu o that the plant is within its design limits, and the power can be safely increased to the next stage.

The initial phase of the approach-to power program will incresse the reactor power and steam conditions in stages until approximately 28%

power when rated steam conditions are achieved. From this level to full power, the reactor power is increased in stages maintaining rated steam conditions. The sequence for the performance of these tests is given in Figure 1, together with the corresponding approximate reactor power levels. The reactor power levels, helium flow rates, feedwater flow rates, steam temperatures, and steam pressure given in the following description of the initial approach-to power may differ somewhat from those in the actual approach to power due to change in test requirements or improvements in operating methods identified during other tests.

In general, the initial approach-to power will be accomplished in the following order:

1. Feedwater flow will first be established through both steam generator loops and the bypass flash tank system using a boiler

r

', s

_4 feedpump. Helium fiow through the core wil; be provided using one circulator in each loop.

2. The reactor power will be increased to approximately 2%.
3. The reactor power, feedwater flow, and helium flow rate will be simultaneously increased to 5% power, 20% helium flow, and 25%

feedwater flow using reactor generated steam from the bypass flash tank supplemented by the auxiliary boiler to power the circulating turbines, turbine driven boiler feedpump, and other plant steam requirements.

4. The reactor power will then be increased to approximately 8%,

concurrent with an increase in feedwater flow to about 30%. The helium flow will be maintained at about 20% during this power increase. At this condition, the second circulator in each loop will be started, maintaining constant helium flow, and the main steam pressure will be increased to 2,400 psig.

5. The reactor power will be increased to about 11%, and feedwater will be reduced to 25% to initiate boiling.

. 4 5-

6. The reactor power will be increased to about 18% simultaneously with an increase in helium flow to about 33%, maintaining 25%

feedwater flow, followed by an increase in reactor power to about 26% with a helium flow of 49%. At this condition, the main steam temperature will be about 800 degrees fahrenheit.

l

7. The helium flow will then be reduced to about 40% concurrent -

with a slight adjustment of the reactor power to about 28%.

8. The reactor power will be increased in stages to about 40%, 50%,

60%, 80%, and finally to 100% of full power. During these power level increases, the helium flow rate through the core will be increased to maintain full steam conditions.

This report covers tests performed between 70% and 100% reactor power.

Each power level was maintained for a period of time to perform one or more of the following tests. Preliminary analysis of these measurements, as specified in the overall controlling test document, was completed prior to increasing the reactor power to the next stage.

r Steam System Performance Tests (B-1)

Just prior to steaming, and at subsequent power levels during the initial rise-to power, data will be accumulated and analyzed on the performance of the steam generators, the turbine, and the steam plant auxiliaries. Measurements of the turbine performance will be made at the lower power levels, and the turbine will be loaded at about 28%

reactor power.

Analysis of Chemical Impurities in the Primary Coolant (B-2)

As the reactor power level is increased to about 11% of rated, the core and reactor internals will experience temperatures in excess of those reached during the core heat-up for reactivity coefficient measurements. At these temperatures, additional impurities will be degassed. Data on the performance of the helium purification system in removing these chemical impurities from the primary coolant will be taken and analyzed.

PCRV Performance Tests (B-3)

As the reactor power level is increased to 28% power, t..a helium pressure and temperatures approach their quarter load values which results in a system heat load of approximately 80%. At each power level stage up to 28% power, and at selected stages up to full power, data will be taken and analyzed on the performance of the PCRV and its cooling system on the structural response of the PCRV to increased internal pressure and on the primary system helium use rate.

Primary Coolant System Performance Tests (B-4)

At each power level, data on the performance of the helium circulators and their auxiliaries will be taken and ar,alyzed.

Measurements of the radial power distribution (region peaking factors) will be made at approximately 2%, 5%, and 8% reactor power.

Data on the performance and calibration of the core helium flow orifice valve will be obtained at approximately 28%, 50%, and 100%

reactor power. ,

Plant Instrumentation Performance Tests (B-5)

In these tests, the performance of the portiens of the plant instrumentation, which could not be tested prior to power operation, will be checked. The nuclear instrumentation will be calibrated by means of heat balance measurements and analyses. The calibration of the condensate and feedwater flow instrumentation and the core region outlet thermocouples will be checked. The core region outlet thermocouple test will be performed just prior to the first adjustment of the helium flow orifices at approximately 8% power and again at approximately 100% power.

Plant Transient Performance Tests (B-6)

In these tests, the transient performance of the plant will be tested and analyzed. The testing will include: a scram and turbine trip from approximately 28% reactor power with rated steam conditions, a turbine trip from approximately 40% reactor power, a main turbine generator load rejection from approximately 60% reactor power to house load, sequential tripping of the two circulators in a loop from

', s .

approximately 80% reactor power and resultant icop shutdown, and boiler feedpump start and stop transients.

Plant Automatic Control System Performance Tests (B-7)

The components of the automatic control system will be placed into service and tested as the controlled variables come into their controllable range. Dynamic verification tests of the control system will be perform"ed at selected power levels during the power level increase of the initial approach to full power. A demonstration of full load change from approximately 100% to approximately 25% turbine load will be made under full automatic control.

Reactor Coefficient Measurements (B-8)

Measurements of changes in reactivity will be made during the approach to full power by measuring the change in control rod positions required to produce a core temperature and reactor power level change.

Differential Control Rod Worth Measurements (B-9)

The reactivity worth of control rods which are moved during the initial rise-to power will be measured using a reactivity computer to obtain the instantaneous reactivity change produced by a control rod motion.

i

e _g_

Xenon Builduo and Decay Measurements (B-10)

The reactivity change produced by buildup, burnout, or decay of xenon poison following a power level change will be measured by recording the change in the critical control rod positions following a change.

Xenon Stability Test (B-11)

In this test, the absence of any sustained xenon oscillations is demonstrated. At 100% power, a perturbation is produced from equilibrium xenon by inserting a control rod in one region and withdrawing a control rod in another region. The indicated power level and region outlet temperatures are recorded as a function of time and analyzed for the presence of any oscillation produced by xenon.

Shieldino Surveys (B-12)

At approximately 28% reactor power and approximately 100% reactor power, surveys of the radiation levels within the plant are perfo rmed. An additional survey is taken during and following any regeneration of the helium purification system. These measured data are recorded and analyzed to demonstrate the adequacy of the shielding design.

Radiochemical Analysis of the primary Coolant (B-13)

In this test, the radioactive gaseous fission products in the primary coolant will be sampled and analyzed. Tnese tests are used in the initial startup phase to define fuel fission product release-to-birth ratio at zero burnup and will yield information on the fraction of' .

failed fuel particle coatings. This test is performed at each major power level of the initial rise-to power.

HISTORICAL

SUMMARY

OF PLANT OPERATION i J

The last testing reported was covered in interim report number 8 for the period ending August 22, 1978. After this, the plant continued operation with the Nuclear Regulatory Commission limit of,70% power.

t In February, 1979, the shutdown for the first refueling was started ,

with the shutdown extending until June, 1979. After startup, normal operation was resumed until September 1, 1979, when the plant was.

shutdown due to inconsistencies found in the safety related piping ,

and hangers. This was found during an audit and analysis committed ,

to by the Company and was reported in Reportable Occurrence 50-267/79-35/01-T-0.

?

/

On September 15, 1979, the reactor was started up and operation /

continued until October 26, 1979, when a maintenance ' shutdown began to install the region constraint devices (RCD). The RCD installation was completed, and the reactor taken critical on December 25, 1979. ,

The RCD's are metal clamps that join the tops of all the regions together to maintain nearly uniform gap flow areas between regions.

Following a reactor scram, 18 helium circulator static seal failed in i

. January,1980, requiring the circulator to be replaced with the spare.

On Februa ry 17, 1980, the reactor was taken critical again, and the

/ Y turbine generator was put o,r. line March 5,1980, c

Operation continued throughout_ the year and into 1981.

On March,16, 1981, Asehdment 23 was issued, which authorized

' fluctuation testing at greater than 70% power. Fluctuation testing Isas-startedonMarch 18, 1981, with power levels of 70% to 88% being l reached during the period April 17 to April 24, and on May 13, 1981.

OnMay13l,1981, the turbine generator tripped on high vibration, due to a loose shroud on the low pressure turbine blading and was follow'ed by a reactor scram. As the turbine repair was to take several weeks, the second refueling outage was started on I May 20, 1981. During this period, 1B circulator was replaced again i

due to another failed static seal.

s The refueling shutdown was finished in July, 1981, and the reactor was taken critical on July 13, 1981. Plant operation has continued throughout the rest of this report period at power levels up to 100%

' and 323 MWe.

TESTING

SUMMARY

c' This , report covers the period from August 23, 1981, through November 22, 1981, and the analysis of the test results collected during the last period of May 23, 1981, to August 22, 1981.

Due to the installation of the region constraint devices and Nuclear .

Regulatory Commission requirements, the B Series Startup Tests, RT-500K (fluctuation testing at greater than 70% power) and RT-485 (control rod drive temperature data collection) were run concurrently, with RT-500K being the controlling document for testing under normal conditions from 40% to 100% power. The test schedule is called out in T-164 (coordination procedure for testing at greater than 70% power) and is included at the end of the test summary section. ,

'l l

Testing' at greater than 70% power was initiated on four occasions.

The first three (April 17, 1981, April 24, 1981, and May 13, 1981) were to a maximum power level of 88%, at which time turbine vibrations necessitated a plant shutdown and the second refueling outage was begun. However, on November 5, 1981, Rt-500K testing again began, and on November 6, the plant attained 100% power. The plant remained at the 100% power leyel for approximately 55 hours6.365741e-4 days <br />0.0153 hours <br />9.093915e-5 weeks <br />2.09275e-5 months <br /> until shutting down on November 9, 1981, to commence a major system modification outage.

3 Based on tests completed so far, the following conclusions can be drawn concerning plant behavior (for details refer to individual B.

Series Test Reports).

1. Steady-state performance above 70Y power was generally satisfactory. However, it was noted that the reheat outlet temperature of module B-2-5 read much lower than the remaining five modules in Loop 2. Although the 20'F range (referred to the average) was not quite met, it is believed that the operating limitations associated with the attendent performance of RT-500 (Fluctuation Testing above 70% Power) resulted in the observed off-normal temperatures. Following normal system operating procedures, expected reheat temperatures can be achieved. Similar situations at lower power levels have been resolved satisfactorily by judicious adjustment of primary t coolant flow orifices and feedwater trim valves. Special
instrumentation outputs are being analyzed by General Atomic.

Preliminary results appear to be acceptable. Unless subsequent investigation reveals inconsistencies or data outsioe of 'B' i

series acceptance criteria, the Fort St. Vrain technical review

) '

1 committee considers SUT B1, Part 1, closed. (B1-1) 4 f

I

2. Steady-state performance of the turbine generator was generally satisfactory. At 100% indicated reactor power, the generator was producing 323 MW(e) versus the expected value of 339 MW(e).

It is postulated that the low feedwater flow may be contributing to the less-than-design output. It is also noted that feedwater 4

heater No. 5 was not in service, nor was a reheat steam temperature of 1000*F being developed. The reheat steam temperature was restricte'd to less than 1000*F due to limitations imposed by the RT-500 fluctuation testing. SUT B1, Part 6 is considered closed. Further investigation into possible feedwater flow discrepancies will be addressed as part of an analysis associated with the results of SUT B5, Part 3,

~

Feedwater Flow Calibration (B1-6)

3. Prima ry coolant impurity levels monitored at 100% power were sati sf actory. The hydrogen getter was not in service; it is being modified by.a change notice. Hydrogen data was not available due to gas chromatograph equipment outage. Primary coolant impurities are monitored on a routine basis as part of normal plant operation. No unresolved issues remain from this startup test. SUT B2, Part 1 is closed. (B2-1)
4. Operation of the purification trains over the past several years have indicated satisfactory performance on a routine basis.

Train operation at 100% appears to be satisfactory in general, despite the fact that data recorded during the 100% power run indicated that the 'B' train (in-service for approximately three months) was showing signs of impurity break-through. However, overall train performance was satisfactory; SUT B2, Part 2 is considered closed. (B2-2)

. L P

5. Gas chromatograph operation and periodic calibration are routine operatons. Results of calibrations performed prior to 100%

powe'r operation were consistent with previous calibrations.

SUT 82, Part 3 is considered closed. (B2-3)

6. Total liner cooling heat load was determined to be between 14 and 17 million BTU /hr. This is consistent with expected values.

Data analysis indicates that the turbine flow meter FE-46165 which measures flow to subheader 4T (PCRV top penetrations, Loop 2) may be indicating a higher flow rate than actually exists. Public Service Company Results Department will investigate. It is also possible that the individual flow meters for the high temperature filter absorber units are out of calibration as evidenced by inconsistent heat loads for the 1

separate cooling tubes. Investigation here is also unde rway.

Based on the results of data collection at 100% power, SUT B3, Part 1Q is considered closed. However, routine system analysis of system performance will be carried out on a regular basis.

(B3-10)

7. Hot spot tube temperature rises were consistent with expected values published in Public Service Company's letter to the Nuclear Regulatory Commission, P-78037. The entire liner cooling system will be monitored on a regular routine basis to assure that 'no significant changes have occurred within either the system or the PCRV. The individual tubes wrapped around the

- g 4' - - -- p~-

o Region 5 top penetration show markedly different temperature rises (21*F versus 9'F). This will be checked. SUT B3, Part IR is considered closed. (83-1R)

8. No subheader or tube valve positions required adjustment during the 100% power run. Subheader 2BS (46248) on the bottom head system should have its indicated flow increased from 109 to 145 gpm to bring the overall system temperature rises into better agreement. SUT B3, Part IS is considered closed.

(B3-15)

9. Two sets of data were collected while operating at 100% power.

The results differed by 30 to 50*F. The lower temperature data set was consistent with previous values collected at lower power. The second set more closely reflected expected temperatures. This data will continue to be collected at regular intervals to establish historical reference information and possible trends. SUT B3, Part 2R is considered closed.

(83-2R)

10. Information collected from the PCRV Data Acquisition System has been anhlyzed and found to be valid. Due to the lack of recent zero (low) PCRV Internal Pressure data, load cell responses could not be reconciled to the acceptance criteria. Public Service Company will, however, provide additional data to

General. Atomic Company for further analysis. The analytical results will be evaluated by Public Service Company. Two instrument channels (100 and 247) will be checked for discrepant response. SUT B3, Part 20 is considered closed pending the above load cell information. However, regular routine data analysis from the PCRV Data Acquisition System will be continued per Public Service Company's established procedures. (B3-20)

11. Helium leakage from the PCRV was negligible. Helium leakage from the PCRV auxiliary piping system was consistent with values observed over the past several years. A substantial purified helium leak into the reheat steam system by way of the Loop 2 steam generator interspaces is known to exist. Overall results of this test were satisfactory. SUT B3, Part 3A is considered closed. Monitoring of plant wide helium leakage will continue on a routine basis. (B3-3A)
12. The data for this test is routinely collected via Public Service Company Surveillance Test 5.2.lba-M, and was performed on November 7, 1981, at 100% power. No discrepant responses ere observed. SUT B3, Part 38 is considered closed. (B3-38)
13. The reactor / primary coolant system was being operated under conditions specified by RT-500 (fluctuation testing). As such, primary system conditions were different than those anticipated

by the SVT acceptance criteria. Primary coolant flow was about 10 to 13% greater than expected based on AP information from sensing points at the circulator inlets. Overall circulator AP was less than expected due to flow resistance values established by RT-500. Continuous operation at 100% reactor power was determined to be satisfactory, and the Fort St. Vrain technical 1 review committee judged that the system performance could be adjusted to meet the desired acceptance criteria if the RT-500 restrictions had not been governing. SUT 84, Part 1 is ,

considered closed. (B4-1(0))

14. Indicated reactor power equals 856 MW(t) (=102%). Actual reactor power depends on accurate measurement of feedwater flow and heat balance calculations plus data logger information.

Some of these data yield power levels of 814 MW(t) (=96.5).

Further effort to refine and otherwise produce more accurate power calculations is needed, especially in the area of feedwater flow accuracies. (See SUT B5, Part 3.) Control rod patterns expected at 100% steady state power were generally achieved. The observed reactivity discrepancy was 0.003aP.

There is a known bias of 0.003AP in the Base Reactivity Curve.

The bias will be corrected when the new Base Reactivity Curve is approved by the Nuclear Facility Safety Committee. This correction will result in a reactivity discrepancy that is essentially zero. SR-5.1.4-W-P testing confirmed the existence of a proper control rod pattern. (B5-1)

15. A broad range of results were observed during SUT B5, Part 2.

The nature of this instrumentation, plus existing recognized

discrepant problems, all contribute to the uncertainties associated with data collected for this SVT. The recorded results were satisfactory, and further indicated that additional con firmatory information be obtained from reduction of fluctuation monitoring data. The Fort St. Vrain Technical Committee further established that acceptance criteria established for this test are believed to be too restrictive, and that routine annual surveillance tests performed recently indicate satisfactory results. Previous core outlet thermocouple traverses recorded in tests RT-509 and RT-524 will be reviewed to confirm adherence with the requirements of LCO 4.1.9. SUT B5, Part 2 is considered closed. (B5-2)
16. The results of SVT B5, Part 3, have concluded that further effort is needed to resolve apparent discrepancies. The SUT itself is declared closed, in that the 100% data wss satisfactorily recorded and the analysis successfully concluded.

The analytical results however, indicate that a more detailed plan must be developed to determine the predominant variables and ranges which contribute to the end result. A Public Service Company T test will be prepared and issued to continue data collection and analysis as required to ultimately resolve the feedwater flowrate issue. General Atomic, San Diego, has advised that certain sensitivity calculations are currently in 4

progress, the results of which may assist Public Service Company

in developing their approach to resolution of feedwater flow discrepancies. (85-3)

17. No fast gas samples were obtained at 100% power due to flow blockage in the sample line. With respect to activity values and radiation background values, recent data indicate a level of about 1/10th of the ar.ticipated values. Operation of the purification system has been fully satisfactory in removing radioactive gases as evidenced by purification train outlet samples.

,, . 3-INITIAL APPROACH TO POWER TESTS (B SERIES STARTUp TESTS)

The init1al approach to power is accomplished in a series of discrete power level stages. At each power level, tests are made to measure .

the characteristics of the plant and to ensure that the plant is within its design limits, and the power can be safely increased to the next stage.

The initial phase of the approach-to power program will increase the reactor power and' steam conditions in stages until approximately 28%

power when rated steam conditions are achieved. From this level to full power, the reactor power is increased in stages maintaining rated steam conditions. The sequence for the performance of these tests is given in Figure 1, together with the correspond!ng-approximate reactor power levels. The reactor power levels, helium flow rates, feedwater flow rates, steam temperatures, and steam presstre given in the following description of the initial approach-to power may differ somewhat from those in the actual approach to power due to change in test requirements or improvements in operating methods identified during other tests.

In general, the initial approach-to power will be accomplished in the following order:

1. Feedwater flow will first be established through both steam generator loops and the bypass flash tank system using a boiler

,, _4

. . i I . .

feedpump. Helium flow through the core will be provided using one circulator in each loop.

2. The reactor power will be increased to approximately 2%.
3. The reactor power, feedwater flow, and helium flow rate will be simultaneously increased to 5% power, 20% helium flow, and 25%

feedwater flow using reactor generated steam from the bypass flash tank supplemented by the auxiliary boiler to power the circulating turbines, turbine driven boiler feedpump, and other plant steam requirements.

4. The reactor power will then be increased to approximately 8%,

concurrent with an increase in feedwater flow to about 30%. The helium flow will be maintained at about 20% during this power increase. At this condition, the second circulator in each loop will be started, maintaining constant helium flow, and the main steam pressure will be increased to 2,400 psig.

5. The reactor power will be increased to about 11%, and feedwater will be reduced to 25% to initiate boiling.

9 t

t

6. The reactor power will be increased to about 185 simultaneously with an increase in helium flow to about 33%, maintaining 25%

feedwater flow, followed by an increase in reactor power to about 26% with a helium flow of 49%. At this condition, the

~

main steam temperature will be about 800 degrees fahrenheit.

1

7. The helium flow will then be reduced to about 40% concurrent with a slight adjustment of the reactor power to about 28%.
8. The reactor power will be increased in stages to about 40%, 50%,

60%, 80%, and finally to 100% of full power. During these power level increases, the helium flow rate through the core will be

increased to maintain full steam conditions.

This report covers tests performed between 70% and 100% reactor power.

Each power level was maintained for a period of time to perform one or more of the following tests. Preliminary analysis of these measurements, as specified in the overall controlling test document, was completed prior to increasing the reactor power to the next i stage, s

s

,,, i . , ,

Steam System Performance Tests (B-1)

Just prior to steaming, and at subsequent power levels during the i

initial rise-to power, data will be accumulated and analyzed on the ,

performance of the steam generators, the turbine, and the steam plant auxiliaries. Measurements of the turbine performance will be made at the lower power levels, and the turbine will be loaded at about 28%

reactor power.

Analysis of Chemical Imourities in the Primary Coolant (B-2)

As the reactor power level is increased to about 11% of rated, the core and reactor internals will experience temperatures in excess of those reached during the core heat-up for reactivity coefficient measurements. At these temperatures, additional impurities will be degassed. Data on the performance of the helium purification system in removing these chemical impurities from the primary coolant will be taken and analyzed.

PCRV performance Tests (B-3)

As the reactor power level is increased to 28% power, the helium pressure and temperatures approach their quarter load values which results in a system heat load of approximately 80%. At each power level stage up to 28% power, and at selected stages up to full power, data will be taken and analyzed on the performance of the PCRV and its cooling system on the structural response of the PCRV to increased internal pressure and on the primary system helium use rate.

j

1 4

primary Coolant System Performance Tests (B-4) p At each power level, data on the performance of the he'ium circulators and their auxiliaries will be taken and analy ed.

Measurements of-~the radial power distribution (region peaking factors) will be made at approximately 2%, 5%, and 8% reactor power.

Data on the performance and calitration of the core helium flow orifice valve will be obtained at approximately 28%, 50%, and 100%

reactor power.

Plant Instrumentation Performance Tests (B-5)

In these tests, the. performance of the portions of the plant instrumentation, which could not be tested prior to power operation, will be checked. The nuclear' instrumentation will be calibrated by means of heat balance measurements and analyses. The calibration of the condensate and feedwater flow instrumentation and the core region outlet thermocouples will be checked. The core region outlet thermocouple test will be performed just prior to the first adjustment of the helium flow orifices at approximately 8% power and again at approximately 100% power.

plant Transient Performance Tests (8-6)

In these tests, the transient performance of the plant will be tested and analyzed. The testing will include: a scram and turbine trip from approximately 28% reactor power with rated steam conditions, a turbine trip from approximately 40% reactor power, a main turbine generator load rejection from approximately 60% reactor power to house load, sequential tripping of the two circulators in a loop from

1 6

approximately 80% reactor power and resultant loop shutdown, and t

boiler feedpump start and stop transients.

plant Automatic Control System performance Tests (8-7)

The components of the automatic control system will be placed into service and tested as the controlled' variables come into their controllable range. Dynamic verification tests of the control system will be performed at selected power levels during the oower level increase of the initial approach to full power. A demonstration of full load change from approximately 100% to approximately 25% turbine load will be made under full automatic control.

Reactor Coefficient Measurements (B-8)

Measurements of changes in reactivity will be made during the approach to full power by measuring the change in control rod positions required to produce a core temperature and reactor power level change.

Differential Control Rod Worth Measurements (B-9)

The reactivity worth of control rods which are moved during the initial rise-to-power will be measured using a reactivity computer to obtain the instantaneous reactivity change produced by a control rod motion.

,. . . .g.

Xenon Buildup and Decay Measurements (B-10) i The reactivity change produced by buildup, burnout, or decay of xenon poison following a power level change will be measured by recording the change in the critical control rod positions following a change.

Xenon Stability Test (B-11)

In this test, the absence of any sustained xenon oscillations is demonstrated. At 100% power, a perturbation is produced from equilibrium xenon by inserting a control rod in one region and withdrawing a control rod in another region. The indicated power level and region outlet temperatures are recorded as a function of time and analyzed for the presence of any oscillation produced by xanon.

Shielding Surveys (B-12)

At approximately 28% reactor power and approximately 100% reactor power, surveys of the radiation levels within the plant are performed. An additional survey is taken during and following any regeneration of the helium purification system. These measured data are recorded and analyzed to demonstrate the adequacy of the shielding design.

Radiochemical Analysis of the primary Coolant (8-13)

In this~ test, the radioactive gaseous fission products in the primary coolant will be scmplet and analyzed. These tests are used in the' initial'startup phase to define fuel fission product release-to-birth ratio at zero burnup and will yield information on the fraction of failed fuel particle coatings. This test is performed at each major power level of the initial rise-to power.

HISTORICAL

SUMMARY

OF PLANT OPERATION The last testing reported was covered in interim report number 8 for the period ending August 22, 1978. After this, the plant continued operation with the Nuclear Regulatory Commission limit of 70% power.

In February, 1979, the shutdown for the first refueling was started with the shutdown extending until June, 1979. After startup, normal operation was resumed until Septemear 1, 1979, when the plant was shutdown due to inconsistencies found in the safety related piping and hangers. This was found during an audit and analysis committed to by the Company and was reported in Reportable Occurrence 50-267/79-35/01-T-0.

On September 15, 1979, the reactor was started up and operation continued until October 26, 1979, when a maintenance shutdown began to install the region constraint devices (RCD). The RCD installation was completed, and the reactor taken critical on December 25, 1979.

The RCD's are metal clamps that join the tops of all the regions together to maintain nearly uniform gap flow areas between regions.

Following a reactor scram, 1B helium circulator static seal failed in January, 1980, requiring the circulator to be replaced with the spare.

l l

l

On February 17, 1980, the reactor was taken critical again, and the turbine generator was put on line March 5, 1980.

Operation continued throughout the year and into 1981.

On March 16, 1981, Amendment 23 was issued, which authorized fluctuation' testing at greater than 70% power. Fluctuation testing was started on March 18, 1981, with pcwer levels of 70% to 88% being reached during the period April 17 to April 24, and on May 13, 1981.

On May 13, 1981, the turbine generator tripped on high vibration, due to a loose shroud on the low pressure turbine blading and was followed by a reactor scram. As the turbine repair was to take several weeks, the second refueling outage was started on May 20, 1981. During this period, 1B circulator was replaced again due to another failed static seal.

The refueling shutdown was finished in July, 1981, and the reactor was taken critical on July 13, 1981. Plant operation has continued throughout the rest of this report period at power levels up to 100%

and 323 MWe.

TESTING

SUMMARY

This report covers the period from August 23, 1981, through November 22, 1981, and the analysis of the test results collected during the last period of May 23, 1981, to August 22, 1981.

l Due to the installation of the region constraint devices and Nuclear ,

Regulatory Commission requirements, the B Series Startup Tests, RT-500K (fluctuation testing at greater than 70% power) and RT-485 (control rod drive temperature data collection) were run i concurrently, with RT-500K being the controlling document for testing under normal conditions from 40% to 100% power. The test schedule is i

called out in T-164 (coordination procedure for testing at greater l than 70% power) and is included at the end of the test summary section.

Testing at greater than 70% power was initiated on four occasions.

The first three (April 17, 1981, April 24, 1981, and May 13, 1981) were to a maximum power level of 88%, at which time turbine vibrations necessitated a plant shutdown and the second refueling outage was begun. However, on November 5, 1981, Rt-500K testing again began, and on November 6, the plant attained 100% power. The plant remained at the 100% power level for approximately 55 hours6.365741e-4 days <br />0.0153 hours <br />9.093915e-5 weeks <br />2.09275e-5 months <br /> until shutting down on November 9, 1981, to commence a major system modification outage.

Based on tests completed so far, the following conclusions can be drawn concerning plant behavior (for details refer to individual B 4

Series Test Reports).

1. Steady-state performance above 70% power was generally satisfactory. However, it was noted that the reheat outlet temperature of module B-2-5 read much lower than the remaining five modules in Loop 2. Although the 20*F range (referred to the average) was not quite met, it is believed that the operating limitations associated with the attendent performance of RT-500 (Fluctuation Testing above 70% Power) resulted in the observed off-normal temperatures. Following normal system operating procedures, expected reheat temperatures can be achieved. Similar situations at lower power levels have been resolved satisfactorily by judicious adjustment of primary coolant flow orifices and feedwater trim valves. Special instrumentation outputs are being analyzed by General Atomic.

Preliminary results appear to be acceptable. Unless subsequent investigation reveals inconsistencies or data outside of 'B' series acceptance criteria, the Fort St. Vrain technical review committee considers SVT B1, Part 1, closed. (81-1)

2. Steady-state performance of the turbine generator was generally satisfactory. At 100% indicated reactor power, the generator was producing 323 MW(e) versus the expected value of 339 MW(e).

It is postulated that the low feedwater flow may be contributing to the less-than-design output. It is also noted that feedwater I

i

~

u .

,3 . . .

heater No. 5 was not in service, nor was a reheat steam

, temperature of 1000*F being developed. The reheat steam temperature was restricted to less than 1000 F $due to limitations imposed by the RT-500 fluctuation testing. SUT B1, Part 6 is considered closed. Further investigation into possible feedwater flow discrepancies will be addressed as part of an analysis associated with the results of SVT B5, Part 3, Feedwater Flow Calibration (B1-6)

3. Primary coolant impurity levels monitored at 100% power were satisfactory. The hydrogen getter was not in service; it is being modified by a change notice. Hydrogen data was not available due to gas chromatograph equipment outage. Primary coolant impurities are monitored on a routine basis as part of normal plant operation. No unresolved issues remain from this startup test. SUT B2, Part 1 is closed. (B2-1)
4. Operation of the purification trains over the past several years have indicated satisfactory performance on a routine basis.

Train operation at 100% appears to be satisfactory in general, despite the fact that data recorded during the 100% power run indicated that the 'B' train (in-service for approximately three months) was showing signs of impurity break-through. However, overall train performance was satisfactory; SUT B2, Part 2 is considered closed. (82-2)

operatons. Results of calibrations performed prior to 100*.

l

! power operation were consistent with previous calibrationsc SUT B2, Part 3 is considered closed. '(B2-3)

6. Total liner cooling heat load was determined to be between 14 and 17 millton BTU /hr. This is consistent with expected values.

1 Data analysis indicates that the turbine flow meter FE-46165 l

whic.h measures flow to subheader 4T (PCRV top penetrations,

! Loop 2) may be indicating a higher flow rate than actually l

l exists. Public Service Company Results Department will ,

investigate. It is also possible that the individual flow meters for the high temperature filter absorber units are out of calibration as evidenced by inconsistent heat loads for the l

separate cooling tubes. In"estigation here is also underway.

Based on the results of data collection at 100*. power, SUT B3, Part 10 is considered closed. However, routine system analysis of system performance will be carried out on a regular basis.

l (B3-10)

7. Hot spot tube temperature rises were consistent with expected values published in Public Service Company's letter to the

! Nuclear Regulatory Commission, P-78037. The entire liner cooling system will be monitored on a regular routine basis to i

l assure that 'no significant changes have occurred within either l

the system or the PCRV. The individual tubes wrapped around the l

Region 5 top penetration show markedly different temperature rises (21 F versus 9'F). This will be checked. SVT B3, Part IR is considered closed. (83-1R)

8. No subheader or tube valve positions required adjustment during the 100% power run. Subheader 2BS (46248) on the bottom head system should have its indicated flow increased from 109 to 145 gpm to bring the overall system temperature rises into better agreement. SUT B3, Part IS is considered closed.

(83-15)

9. Two sets of data were collected while operating at 100% power.

The results differed by 30 to 50*F. The lower temperature data set was consistent with previous values collected at lower power. The second set more closely reflected expected temperatures. This data will continue to be collected at regular intervals to establish historical reference information and possible trends. SUT B3, Part 2R is considered closed.

(B3-2R)

10. Information collected from the PCRV Data Acquisition System has been analyzed and found to be valid. Due to the lack of recent zero (low) PCRV Internal Pressure data, load cell responses could not be reconciled to the acceptance criteria. Public Service Company will, however, provide additional data to m

+

,e .

s General Atomic Company for further anal / sis. The analytical results will be evaluated by Public Service Company. Two instrument channels (100 and 247) will be checked for discrepant

.l response. SUT B3, Part 20 is considered closed pending the above load cell information. However, regular routine data analysis from the PCRV Data Acquisition System will be continued per Public Service Company's established procedures. (B3-20) 3

11. Helium leakage from the PCRV was negligible. Helium leakage from the PCRV auxiliary piping system was consistent with values observed over the past several years. A substantial purified helium leak into the reheat steam system by way of the Loop 2 steam generator interspaces is known to exist. Overall results of this test were satisfactory. SVT B3, Part 3A is considered closed. Monitoring of plant wide helium leakage will continue on a routine basis. (B3-3A)
12. The data for this test is routinely collected via Public Service Company Surveillance Test 5.2.lba-M, and was performed on November 7, 1981, at 100% power. No discrepant responses were observed. SUT B3, Part 3B is considered closed. (B3-38)
13. The reactor / primary coolant system was being operated under conditions specified by RT-500 (fluctuation testing). As such, primary system conditions were different than those anticipated I

- - - , , =,

s by the SVT acceptance criteria. Primary coolant flow was about 10 to 13% greater than expected based on AP information from sensing points at the circulator inlets. Overall circulator AP was less than expected due to flow resistance values established by RT-500. Continuous operation at 100% reactor power was determined to be satisfactory, and the Fort St. Vrain technical review committee judged that the system performance could be l

adjusted to meet the desired acceptance criteria if the RT-500 restrictions had not been governing. SVT 84, Part 1 is considered closed. (B4-1(0))

14. Indicated reactor power equals 856 MW(t) (=102%). Actual reactor power depends on accurate measurement of feedwater flow and heat balance calculations plus data logger information.

Some of these data yield power levels of 814 MW(t) (=96.5).

Further effort to refine and otherwise produce more accurate power calculations is needed, especially in the area of feedwater flow accuracies. (See SVT B5, Part 3.) Control rod patterns expected at 100% steady state power were generally achieved. The observed reactivity discrepancy was 0.003aP.

There is a known bias of 0.003aP in the Base Reactivity Curve.

The bias will be corrected when the new Base Reactivity Curve is approved by the Nuclear Facility Safety Committee. This correccion will result in a reactivity discrepancy that is essentially zero. SR-5.1.4-W-P testing confirmed the existence of a proper control rod pattern. (85-1)

i

15. A broad range of results were observed during SVT B5, Part 2.

The nature of this instrumentation, plus existing recognized discrepant problems, all contribute to the uncertainties associated with data collected for this SUT. The recorded results were satisfactory, and further indicated that additional confirmatory information be obtained from reduction of fluctuation monitoring data. The Fort St. Vrain Technical Committee further established that acceptance criteria established for this test are believed to be too restrictive, and that routine annual surveillance tests performed recently indicate satisfactory results. Previous core outlet thermocouple traverses recorded in tests RT-509 and RT-524 will be reviewed to confirm adherence with the requirements of LCO 4.1.9. SUT B5, Part 2 is considered closed. (BS-2)

16. The results of SUT B5, Part 3, have concluded that further effort is needed to resolve apparent discrepancies. The SUT itself is declared closed, in that the 100% data was satisfactorily recorded and the analysis successfully concluded.

The analytical results however, indicate that a more detailed plan must be developed to determine the predominant variables and ranges which contribute to the end result. A Public Service Company T test will be prepared and issued to continue data collection and analysis as required to ultimately resolve the feedwater flowrate issue. General Atomic, San Diego, has advised that certain sensitivity calculations are currently in progress, the results of which may assist Public Service Company

I in developing their approach to resolution of feedwater flow discrepancies. (85-3)

17. No fast gas samples were obtained at 100% power due to flow blockage in the sample line. With respect to activity values and radiation background values, recent data indicate a level of about 1/10th of the anticipated values. Operation of the purification system has been fully satisfactory in removing radioactive gases as evidenced by purification train outlet samples. This SUT is considered closed, however, further analyses of the primary coolant will be obtained via routine

! surveillance programs augmented by Public Service Company T-test i

performance as required. (B13-1)

18. The iodine analysis test was in progress at the time of the 0155, November 9, 1981 plant shutdown, and no complete data was collected. This test will be repeated at 100% power at the next opportunity. This test is considered open. (13-2)
