MALFUNCTION OF ROD CONTROL AND INDICATION SYSTEM
( Attachment 1 - Indications of Misaligned Rod Sheet 1 of 1 The table below indicates the varjation in plant parameters which may be indicative ohod misalignment. This variation refers to relative changes in indication from a reference condition at which the suspect rod's position was known to be properly aligned. The reference case may be taken from prior operating records, or it may be updated each time the proper rod positioning is verified by in-core measurements. In general, greater misalignment will cause larger variations. Variations in NI channel indication are also affected by the core location of the suspect rod. For example, a misaligned.rod that is closest to the N-44 detector should indicate that N-44 flux parameters are abnormal when compared with flux parameters of the other Power Range NI channels. If the parameters below exhibit no abnormal variations with an individual DRPI differing from its group step counter demand position by more than 12 steps, it is probably a rod position indication problem.
PLANT PARAMETER VALUE INDICATIVE OF ROD MISALIGNMENT Quadrant Power Tilt Ratio (QPTR) Greater than 1.02 .
Power Range Instrumentation Greater than 2% difference between any two channels (REFER TO Attachment 4)
Delta Flux Indicators Greater than 2% difference between any two channels (REFER TO Attachment 4)
Core Outlet Thermocouples Greater than 10°F difference between thermocouples adjacent to the misaligned rod and the average of symmetric thermocouples (PERFORM Attachment 2)
Axial Flux Traces (in-core movable CONSULT Reactor Engineering detector) AND EVALUATE using in-core movable detectors per EST-922, Control Rod Position Determination Via Incore Instrumentation

MALFUNCTION OF ROD CONTROL AND INDICATION SYSTEM
( Attachment 1 - Indications of Misaligned Rod Sheet 1 of 1 The table below indicates the variation in plant .parameters which may be indicative of rod misalignment. This variation refers to relative changes in indication from a reference condition at which the suspect rod's position was known to be properly aligned. The reference case may be taken from prior operating records, or it may be updated each time the proper rod positioning is verified by in-core measurements. In general, greater misalignment will cause larger variations. Variations in NI channel indication are also affected by the core location ()f the suspect rod. For example, a misaligned rod that is closest to the N-44 detector should indicate that N-44 flux parameters are abnormal when compared with flux parameters of the other Power Range NI channels. If the parameters below exhibit no abnormal variations with an individual DRPI differing from its group step counter demand position by more than 12 steps, it is probably a rod position indication problem.
PLANT PARAMETER VALUE INDICATIVE OF ROD MISALIGNMENT Quadrant Power Tilt Ratio (QPTR) Greater than 1.02 Power Range Instrumentation Greater than 2% difference between any two channels (REFER TO Attachment 4)
(~. Delta Flux Indicators Greater than 2% difference between any two channels (REFER TO Attachment 4)

1.0, PURPOSE
(
NOTE: If the requirement to perform a SOM Calculation is time critical, the Manual Calculation ha$ been evaluated to be the preferred method.
- 1. Provide methods to ensure thatRCS boron concentration has a shutdown margin greater than 1770 pcm in Modes 1 and 2, through the use of calculations ..
2~ Provide methods to ensure that RCShas an adequate shutdown margin by verifying the RCS boron concentration is greater than the minimum required boron concentration in Modes 3 through 5.
- 3. This procedure satisfies the requirements of Technical Specification Surveillance Requirements 4.1.1.1.1.a, 4.1.1.2.a and 4.1.1.2.b.
NOTE: The boron concentration to satisfy FSAR Section 6.3.2.8 takes credit for all control rods being inserted into the core and does NOT satisfy Technical Specification SOM requirements.
- 4. This procedure calculates the RCS boron concentration required by FSAR Section 6.3.2.8 to block SI actuation signals.

3.0 PREREQUISITES
- 1. The performance of this OST has been coordinated with other plant evolutions such that the minimum equipment operating requirements of Tech Specs are met.
- 2. OBTAIN any tools and equipment required per Section 5.0.
- 3. OBTAIN Unit SCO permission to perform this OST.
Signature Date 4.0 PRECAUTIONS AND LIMITATIONS
- 1. If either of the following conditions exist, initiate emergency boration per AOP-002 and continue until the required shutdown margin is achieved:
- In Modes 1 and 2, shutdown margin is less than 1770 pcm, OR
- In Modes 3 - 5 shutdown margin is less than required by PLP-106, Technical Specification Equipment List Program and Core Operating Program.
- 2. Projected conditions should be for the minimum shutdown margin expected in the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless a manual Xenon free calculation is performed. (This precaution is N/A if performing Section 7.4)
- 3. IfPOWERTRAX is being used it should have been updated with recent power history (less than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during steady state operation).
- 4. The POWERTRAX program cannot be run out long enough to calculate a totally Xenon-free value for SDM for any given time. To obtain Xenon Free data, either use the SOR Minimum Boron which is shown on any SDM printout, or perform a manual SDM calculation per Section 7.2.
- 5. Rod worth provided in this procedure for control banks, shutdown banks, and most reactive rod are the most conservative values for Cycle 15 only.
Subsequent fuel cycles will require a change to this procedure.
- 6. Samarium is considered in the assumptions used to develop the curve inputs and as a fixed input to the POWERTRAX transient calculations.
IOST-1036 Rev. 39 Page 4 of 351
4.0 PRECAUTIONS AND LIMITATIONS (Cont.)
- 7. The required minimum boron concentration usually varies with xenon decay. It is necessary to select a time and temperature based calculation that corresponds to planned plant evolution, and repeat this calculation as necessary if the plan changes.
- 8. Powertrax is an ICON based computer program. After a calculation is completed, positioning the mouse on a specific node located on the graph and clicking the center mouse button will display the parameters for that specific node. If the mouse is a two button unit the equivalent fUnction is obtained by depressing both buttons at the same time. This. function can be used as many times. as desired and allow a printout of the specific time/data points needed.
- 9. The Powertrax Shutdown Boron Concentration Module printout will show the Xenon free boron as SOR Minimum Boron. The minimum shutdown boron for the projected time will be listed in the table specific to the temperature under the "ppm Btl column.
- 10. The requirement to be borated to cold shutdown conditions prior to blocking SI is based on a commitment contained in FSAR Section 6.3.2.8.
This requirement ensures that if a steam line break occurs after SI has been blocked, the resultant cooldown will not resultinretum tb criticality~
The required value is not the Tech Spec shutdown margin; therefore, it is acceptable to credit the worth of all control rods inserted.
- 11. To ensure the requirements of FSAR Section 6.3.2.8 are met, prior to blocking SI, the RCS r:nust be borated to cold shutdown.

3.0 PREREQUISITES NOTE: Precaution and Limitation 4.0.1 has guidance if performing this OST with one Power Range Channel inoperable.
- 1. VERIFY instrumentation needed for the performance of this test is free of deficiencies that affect instrument indication.
- 2. VERIFY the most recent Curve F-x-8 is used in the performance of this procedure. (Reference 2.1.1 and 2.1.2)
Curve F-x-8 Revision Number _ _ _ _ _~
- 3. OBTAIN Unit SCO permission to perform this OST.
Signature Date 4.0 PRECAUTIONS AND LIMITATIONS
- 1. With one power range channel inoperable, this OST shall be performed using the remaining three detectors. In addition, if Reactor Power is greater than 75%, EST-915 must also be performed per Surveillance Requirement 4.2.4.2. (Reference 2.1.3)
- 2. If performing this OST to support NIS calibration (MST-10044, 10045, 10046, and 10047), then new calculated currents on Curve F-x-8 are to be used per OP-1 05. (Reference 2.1.1)
- 3. There is usually a time lapse between the generation of the new curve values and the calibration of the power range Nls. Operations should approve the new curve with the QPTR alarm operable. The installed NI currents are outdated and will not be the same as the new values on the curve. This is conservative since the QPTR alarm will actuate when actual QPTR is below the setpoint. If the QPTR alarm actuates, the new curve values should be used in the calculation. These values reflect core conditions from the most recent flux map.

3.0 PREREQUISITES NOTE: Precaution and Limitation 4.0.1 has guidance if performing this OST with one Power Range Channel inoperable.
- 1. VERIFY instrumentation needed for the performance of this test is free of deficiencies that affect instrument indication.
- 2. VERIFY the most recent Curve F-x-8 is used in the performance of this procedure. (Reference 2.1.1 and 2.1.2) .
Curve F-x-8 Revision Number ------
- 3. OBTAIN Unit SCO permission to perform this OST.
Signature Date 4.0 PRECAUTIONS AND LIMITATIONS
- 1. With one power range channel inoperable, this OST shall be performed using the remaining three detectors. In addition, if Reactor Power is greater than 75%, EST-915 must also be performed per Surveillance Requirement 4.2.4.2. (Reference 2.1.3)
- 2. If performing this OST to support NIS calibration (MST-10044, 10045, 10046, and 10047), then new calculated currents on Curve F-x-8 are to be used per OP-105. (Reference 2.1.1)
- 3. There is usually a time lapse between the generation of the new curve values and the calibration of the power range Nls. Op~rations should approve the new curve with the QPTR alarm operable. The installed NI currents are outdated and will not be the same as the new values on the curve. This is conservative since the QPTR alarm will actuate when actual QPTR is below the setpoint. If the QPTR alarm actuates, the new curve values should be used in the calculation. These values reflect core conditions from the most recent flux map.

Initial Conditions:
- The unit is being shut down for refueling and a planned crud burst is in progress.
- The RAB AO is being directed to enter an area to align several valves. He is the only AO available to perform this task.
- This individual was employed at North Anna earlier this same year. At North Anna he received a combined 3,486 mRem TEDE during routine and emergency repair work response.
- The estimated dose rate in the area is 520 mRem/hr. An airborne contamination concern also exists.
- It is estimated that it will take approximately 20 minutes to complete the alignment if he uses a respirator. If he does NOT wear a respirator, the alignment will take only 10 minutes, but Radiation Protection projects that your internal exposure will be 8 DAC-hrs.
Initiating Cue: 1. Determine the resultant total effective dose equivalent for both with a respirator (1.a) and without a respirator (1.b).
- 2. Using the lowest dose determined in number 1, determine if the individual can perform the task without exceeding Progress Energy's Annual Administrative Dose Limit.

./ Performance Step: 8 Determines individual's total exposure for the year if the work is allowed without a respirator Standard: Determines individual's total exposure for the year if the work is allowed to be 3941.7 mRem (3835 mRem + 106.7 = 3941.7)
(NOTE: Could round to 3942 tolerance +/-2)
Note: If calculated wearing a respirator the total exposure for the year will be 4008.3 mRem and work cannot be performed. The directions were to use the lowest dose and this represents UNSAT performance.
(NOTE: Could round to 4008 tolerance +/-2)

Appendix C Page 6 of 10 Form ES-C-1 PERFORMANCE INFORMATION KEY 1.a Calculation for resultant total effective dose equivalent with a respirator.
Determines internal exposure to be ZERO while wearing a respirator Determines external exposure to be 173.3 mRem TEDE while wearing a respirator (520 mRem / hr x 20 min = 173.3 mRem)
(NOTE: Could round to 173 tolerance +/- 2)
Determines TOTAL exposure while wearing a respirator (0 mRem internal + 173.3 mRem external = 173.3 mRem total)
(NOTE: Could round to 173 tolerance +/- 2)
Determines individual's total exposure for the year to be 3835 mRem (3485 mRem + 349 mRem = 3835 mRem)
Determines individual's total exposure for the year if the work is allowed to be 4008.3 mRem (3835 mRem + 173.3 = 4008.3)
(NOTE: Could round to 4008 tolerance +/-2)
Note: If calculated wearing a respirator the total exposure for the year will be 4008.3 mRem and work CANNOT be performed. The directions were to use the lowest dose and this represents UNSAT performance.
1.b Calculation for resultant total effective dose equivalent without a respirator.
Determines internal exposure to be 20 mRem while not wearing a respirator (2.5 mRem / hr x 8 DAC-hr = 20 mRem)
(NO tolerance)
Determines external exposure to be 86.7 mRem TEDE while not wearing a respirator (520 mRem / hr x 10 min = 86.7 mRem)
(NOTE: Could round to 87 tolerance +/-2)
Determines total exposure to be 106.7 mRem while not wearing a respirator (20 mRem internal + 86.7 mRem external = 106.7 mRem total)
(NOTE: Could round to 107 tolerance +/-2 )
Determines individual's total exposure for the year if the work is allowed to be 3941.7 m Rem (3835 mRem + 106.7 = 3941.7)
(NOTE: Could round to 3942 tolerance +/-2)

Appendix C Page 9 of 10 Form ES-C-1 JPM CUE SHEET INITIAL CONDITIONS: The unit is being shut down for refueling and a planned crud burst is in progress.
The RAB AO is being directed to enter an area to align several valves. He is the only AO available to perform this task.
This individual was employed at North Anna earlier this same year. At North Anna he received a combined 3,486 mRem TEDE during routine and emergency repair work response.
In the same calendar year while working at HNP, he has received another 349 mRem TEDE.
The estimated dose rate in the area is 520 mRem/hr. An airborne contamination concern also exists.
It is estimated that it will take approximately 20 minutes to complete the alignment if he uses a respirator. If he does NOT wear a respirator, the alignment will take only 10 minutes, but Radiation Protection projects that your internal exposure will be 8 DAC-hrs.
INITIATING CUE: 1. Determine the resultant total effective dose equivalent for both with a respirator (1.a) and without a respirator (1.b)
- 2. Using the lowest dose determined in number 1, determine if the individual can perform the task without exceeding Progress Energy's Annual Administrative Dose Limit.
