Refer to Attachments 1 and 2 for the depiction of the main steam pressure loop string. Attachment 1 represents EFIC Channels A and B. Attachment 2 represents EFIC Channels C and D.
Il DESIGN INPUTS (DI)
- 1. Drawings that define the loop configuration and components; 205-039, sheets MS-01, MS42, MS-03, MS-04 MS-05 and MS-06 (Reference 24 thru 29).
- 2. Pressure transmitters MS-106-PT through MS-113-PT are located in the Intermediate Building.
(1) Per drawing 308-129 (Reference 30), MS-110-PT and MS-112-PT are located on the south face of a structural column on column line 310 and between rows 11/J2; and 53 inches above floor elevation 119'-0" in the Intermediate Building.
(2) Per drawing 308-129 (Reference 30), MS-111-PT and MS-113-PT are located on the southem structural wall at column line 310 and row K1; and 53 inches above floor elevation 119'-0" in the Intermediate Building.
(3) Per drawing 308-130 (Reference 31), MS-106-PT and MS-108-PT are located on the northwest edge of the structural platform adjacent to the stairs between column lines 309/310 and rows G/H1; and 53 inches above floor elevation 119'-0" in the Intermediate Building.
(4) Per drawing 308-130 (Reference 31), MS-107-PT and MS-109-PT are located on the southwest edge of the structural platform between column lines 309/310 and rows H1/11; and 53 inches above floor elevation 119'-0" in the Intermediate Building.
Per CMIS, MS-106-PT thru MS-113-PT are located in EO Zone 16. Per the Environmental and Seismic Qualification Program Manual (E/SOPM - Reference 8) EO Zone 16 is " HARSH" and has the following specifications:
Radiation - Normal: " 0 x 108rads TID for 40 year Juse.
Radiation - Accident: 1.5 x 10' rads TID (40 year TID + 6 months).
Temperature - Normal: 80 to 135 F.
Temperature - LOCA: The same as
- Normal" Temperature - HELB: 149 to 417 F.
Per drawing 308-129 (Reference 30) and 308-130 (Reference 31), the sensing lines are routed near the proximity of the main steam lines and do not go outside the structural boundary of the intermediate Building area.
- 3. Enhanced Design Basia Document for Post Accident instrumentation, Tab 5/11, (Reference 4), states that the main steam pressure is a R.G.1.97 Type A, D, Cat.1 variable, as indicated and recorded in the control room and on demand in the TSC and EOF (provided by RECALL).

The post-accident LOCA (RB) and post-accident HELB (IB) environment are different and both will be used to determine the error for post-accident monitoring (PAM) Instrumentation.
- 4. Enhanced Design Basis Document for Emergency Feed Water and Emergency Feedwater initiation and Control (EFIC), Tab 6/13, (Reference 5) states that the main steam pressure is used to initiate EFIC on low pressure in either steam generator (SG), and " feed only good generator" (FOGG) as determined by SG differential pressure. Main steam pressure is also used to compensate for SG fluid density and in determination of level control in the steam generators.
- 5. Enhanced Design Basis Document for the Main Steam System, Tab 6/10, (Reference 6) Section 3 notes the CR-3 Safety Analysis assumes the Atmospheric Dump Valves (ADV's) operate for Steam Generator Tube Rupture tSTC% loss of electric power and Steam Une Break (SLB). The SLB is the only scenario which will cause a harsh er,vironment for the transmitters in the 18. The Analysis Basis Document for Steam Une Break (Reference 62) notes four cases (scenarios), where cases I, il and IV assume the ADV's are available in the analysis to function. The FSAR Section 14.2.2.1.4, (Reference 3) notes cases I,11 and IV are breaks within the RB, and therefore would not cause a harsh environment for the transmitters in the 18. Therefore a non-accident environment will be used for ADV actuation loop error.
- 6. Enhanced Design Basis Document for Remote Shutdown System, Tab 5/9, (Reference 58) gives the main steam pressure range of 0 to 1200 psig. No accuracy requirements are given. Improved Technical Specification Section 3.3.18 (Reference 2) gives the requirements for remote shutdown.
- 7. Instrument Data Sheets MS-106-PT thru MS-113-PT (References 23g,230,23t,23x,23ee,2311,23qq and 23uu) show that the pressure transmitters are Rosemount Model 1154SH9RA pressure transmitters with a span of 0 to 1200 psig. The specifications for these transmitters are described in Instruction Manual #1896 (Reference 40). The transmitters have the following specifications (See Attachment 3):
Upper Range Limit (URL): 3,000 psig.
Reference Accuracy: 2 0.25% of calibrated span.
Temperature Effect: (0.15% URL + 0.35% span)/50 F, between 40 F and 130 F.
2 (0.75% URL + 0.5% span)/100 F, between 40 F and 200 F. (See Attachment 17)
Drift (Stability): : 0.2% of upper range limit for 18 months. Attachment 16 documents that the published drift specification is applicable for 30 months.
Overpressure Effect: 0.5% of upper range limit after exposure to 4,500 psig.

(1) Per VQP INST-R36944 (Reference 21), Tab F1, pages 9 & 10, the Rosemount product specification for j radiation effects for the first 30 minutes was established based on radiation testing where the test units l were exposed to an accident dose rate of 2.07X10' R/Hr for the first 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The dose at end of the first 30 minute exposure would be 1.035x10' R (a quarter of the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> dose), and considerably more than our expected radiation dose for Zone 16 (1.5X10' R for 40 years plus 6 months post-accident).
Therefore the Rosemount product specification radiation accuracy term for the first 30 minutes is applicable for the error analysis under considerations (2) Per the Enhanced Design Basis Document for the Main Steam System, Section 6/10 (Reference 6), the main steam code safety valves prevent the rise in the main steam pressures and the last bank of code safeties open at a set pressure of 1100 psig. Therefore, the overpressure effect for the pressure transmitters will be considered as t 0.0% since the pressure transmitters will not experience 4,500 psig.
(3) Per Letter LFM90-0006 (Reference 42); *lt is not required to apply LOCA + MHE simultaneousiv to system functions." Thus, a Seismic event (MHE) and a LOCA do not need to be considered to occur simultaneously. Therefore, this calculation wHl only consider the LOCA/HELB effects (Radiation Effect and Steam / Temperature Effect) since the Seismic Effect is less than the LOCA/HELB effects. Therefore, the Seismic effect will be considered as t 0.0% for Normal and Accident conditions.
(4) Per Letter SNES94-0276 (Reference 43); " ..Rosemount has stated that any of these radiation induced errors may be compensated by calibration un to the tested dose from environmental cualification testino or about 110 MRads. Thus, it is shown that compensation of the radiation induced errors by calibration is a viable method up to the qualification level of 110 MRads.
Per the Attachment to Letter SNES94-0276; "The lower the dose rate, the lesser the effect on instrument accuracy. For the lower dose rates (10' Rads / hour) it was shown that a TID of less than 1 x 10' Rads resulted in a maximum output shift within the stated accuracy of the transmitter. These results are meant to be an aid in determining effects of radiation on accuracy of Rosemount transmitters."
The highest dose rate expected for MS-106-PT thru MS-113-PT is 1.5 x 10' rads for 40 years plus 6 months per Design input (DI) #2, therefore, the radiation effect for NORMAL operating conditions will be considered as t 0.00% since the transmitters receive less than 1 x 10' rads.
(5) The normal performance specification limits for temperature effects will be replaced by the steam pressure / temperature effects whenever the ambient conditions exceed the specified Rosemount temperature limits of 40*F to 200'F.
(6) Since the condtions required for the steam pressure / temperature effect during normal operating condition is not applicable, therefore the reormal steam pressure / temperature effect will be considered as 10.0 %.
(7) The pressure transmitters installed are Rosemount Model 1154SH Range code 9 and according to the manufacture's product literature (Attachment 3) these units have a sealed reference leg. This sealed reference chamber was not evacuated nor was it sealed with a calibrated standard of atmospheric pressure. The chamber was plugged with a pocket of air at whatever the atmospheric condition was at the time of assembly. Because the chamber was not sealed with a known reference, there could be an effect on the transmitters ability to correctly measure the process pressure. This effect will be evaluated under process measurement errors in the Detailed Calculations section to establish the amount of uncertainty this effect can contribute to the pressure reading.

- 20. Calculation I-884009 (Reference 15) depicts a generic 4 - 20 mADC instrument sensor circuit and covers the design input aspects given to the derivation of the insulation resistance error equation. The circuit presented in the calculation is a representation of ungrounded voltage power supply loop. Also, the calculation itself is only concemed with the current leakage path resulting from a degradation of dielectric material to cause a conductor to conductor IR affect. For a conductor to conductor current leakage path configuration this results in an insulation resistance loop error of magnitude in the positive direction.

Tracing the common (or negative) side wiro leads has shown that these are all grounded to an isolated instrument ground bus within the cabinet which is tied to the plant's instrument ground grid. This loop configuration differs from the generic application covered in calculation I-88-0009 (Reference 15), where two additional current leakage paths are now introduced for a grounded voltage source.
I Consideration is now given to looking at a grounded transmitter loop configuration in a harsh environment where a conductor to ground current leakage path is created on the positive side of the loop. A leakage path on the positive side of the circuit causes an increase in the current output from the voltage source .
The consideration of this resistive ground path can be ignored since the voltage source will maintain the increase in current load and not affect the current path through the transmitter and the instrument load resistance. The second consideration that needs to be taken into account is a conductor to ground current leakage path on the common (or negative) side of the circuit which results in the leakage path bypassing a portion of the transmitter current around the load impedance (R,) to the common side of the voltage source through the ground path. The leakage current in this case is a negative bias opposed to the positive bias noted in the first consideration. The magnitude of this current is a function of the leakage path to ground resistance and voltage drop across the loop resistance. Therefore, this ground leakage is greatest on the full signal output for the loop when the transmitter current is 20 mADC, as opposed to the conductor to conductor leakage being the greatest at minimum signal (i.e. 4 mADC).
Utilizing the approach given in calculation I-884009 (Reference 15) for determination of the IR error, except considering the transmitter current at 4 mADC, the following equation will be used in calculating the positive bias IR error for a conductor to ground transmitter circuit loop:
A,, = + [(V, R.f )r / (I. x {R, + R,})] x 100 where: V, = power supply voltage = 32 volts R, = equivalent resistance of the loop in a mild environment = 625 ohms is = I op current span = 16 mA ly = loop current across the transmitter = 4 mA.
R, = equivalent parallel resistance of the cables, splices and connectors in a harsh environment.
Substituting the constants into the equation, we have; A,, = + [(32 - (625 x 0.004) ) / (0.016 x {625 + R,})] x 100
= + [(32 - 2.5) / (10 + 0.016R,)] x 100
= + [29.5 / (10 + 0.016R,)] x 100 Again utilizing the approach given in calculation I-884009 (Reference 15), the following equation will be used it. mlculating the negative bias IR error due to a conductor to ground current leakage path on the common (or negative) side of the transmitter loop circuit:

- 21. The cables used in the instrument loops are CR-3 Bill Of Material (B.O.M.) type EK-35A, EK-36A and EK-37A which are all 2 conductor #16 AWG cable. Vendor Qualification Report CABL-B365-01 (Reference 18) is used to determine the IR value associated with these cable types. Per Tab 11 of the VOP, all of the cable has similar construction as the BlW (Boston insulated Wire) Bostrad 7E, whose test results are documented under the VOP.
The peak temperature in the Intermediate Building (IB) is 417'F per Design Input (DI) #2. This temperature peak in the IB lasts approximately 31 seconds before returning to 300 F within 3 minutes. BlW Bostrad 7E cable was tested under Sandia National Laboratories Report SAND 89-1755C which is included as Attachment B2 to Calculation 1-89-0004 (Reference 14). Per Conclusion 4.e of the Sandia report;
' Total thermal lag time was typically 3 minutes for multi-conductor cables and 30 seconds for single conductors." Under Tab 18, page 2 of the VCP report a thermal finite element analysis found that the BlW when installed in conduit is exposed to a maximum temperature excursion of 338 F before falling off to below 300'F. Therefore the minimum cable IR of 2.9 x 10' ohms for the 20 foot specimen length, which is listed in Figure 7 of VOP CABL-B365-01 (Reference 18) will be used in this calculation. Therefore, the following information is applicable:
Specimen Length (Lsa): 20 feet. Minimum IR value (Rc): 2.9 x 10' ohms at 300'F. The cable IR (Rei) is derived from the cable qualification test specimen IR (Rc ), the specimen length (L,a) and the total length of cable in the HARSH environment (Lexy), in feet. Therefore, the following formula is used: Re, = (Rex L a)/Qx,
- 22. Based on the Walkdown Packa0es for transmitters MS-106-PT thru MS-113-PT (Reference 22), the splices in the circuits associated with MS-106-PT thru MS-113-PT consists of butt splices with Raychem heat shrink tubing. No non-standard splice configurations were identified. The splices at the transmitters were identified as having Raychem WCSF-N tubing sleeves; therefore, VOP TERM-R098-04 (Reference 20) which documents the test data associated with Raychem WCSF-N splice sleeves will be used for this calculation.
Per Tab F5 of the VOP (Wyle Test Report 58442-1), each test circuit consists of three (3) test splices each consisting of a single layer of WCSF-N sleeving. Per Table 1 of the test report, the minimum IR during the simulated LOCA/MSLB :est was: Cable Splice (R.): 1.8 x 10' ohms at 314 F (excluding the test specimens that had cable insulation failures). Figure 1 of Tab D1. in the above mentioned VOP, describes the thermallag associated with the Raychem sleeving. The RB temperature profile and the thermal tag associated with the Raychem sleeving cross at approximately 310*F. Therefore, the use of the 1.8 x 10' ohms at 314 F is acceptable.

Tab F3, page 4 and 38; specify that a Swagelok fitting and a length of copper tubing be used to seal the electrical conduit entries in preparation for testing the units in a steam / temperature environment within a steam chamber. No conduit seal assembly was used for the test duration. Tab B -
Summary of Qualification; Paragraph 3.1 within the VQP instructs the use of a Rosemount 353C conduit seal to avoid moisture intrusion into electronics housing portion of the transmitter assembly. The walkdown packages covering the transmitter installations identified that a conduit seal connector was fitted onto each transmitter's electronic housing. VQP PEN-R36941 (Reference 19) documents the testing of the Rosemount Model 353C conduit seal. Calculation I-88-0003 (Reference 13) calculated an IR based upon the acceptance criteria given in the test report, in which the voltage measured across the 500 ohm resistor in the test loop could not shift by more than 40 mV. According to the calculation, the test set-up used in the qualifict'on test measured total leakage (lead-to-lead and leads-to-case). It further added that since it is not possible to determine how the leakage is divided, all measured leakage current was assumed to be lead-to-lead leakage. The calculation then used the 40 volts between the seal leads to arrive at an IR value of 5 x 10' ohms. This value is conservative since it represents the maximum allowed deviation for the conduit seal and is used in the instrument string error calculation for the post accident monitoring conditions. Conduit Seal (Rd: 5 x 10 5ohms for temperatures up to 420*F, based on the above mentioned VQP. In deterinination of an IR value for the low pressure initiate condition, a more realistic approach needs to be taken in order demonstrate that the conduit seal IR affect when combined with the other component IR's has a negligible affect on the string error. To arrive at this conclusion the actual test data from the VQP is used to determine the appropriate IR value. Rosemount tested two different design seal configurations and according to Tab 14, page 2, the conduit seals fumished to CR-3 are of the Design 2 configuration. Per Tab F. Appendix A, page 18, the initial LOCA test was interrupted due to steam escaping from the chamber and an inspection was performed of the test units which revealed that the heat shrink tubing on the lead wires of the units had been perforated during the test setup. A modification of the configuration was made, and the units were re-tested. The results of the test showed that a maximum shift of 21 mV was observed on unit A003 during the first test and 4 mV during the re-test. The other unit (A001) had suffered degradation; therefore, test data will be based on unit A003. l According to Tab 2, Sections 17.3.1 and 17.3.2 of the VOP PEN-R36941 (Reference 19), the acceptance criteria during the LOCA test for voltage shifts across the 500 ohm resistor and the IR measurement was 40 mV and 6 x 10' ohms. This IR measurement was to be taken from lead-to-case, as prescribed in Sections 17.2.4 and 10.1.2.4.2. Although the test procedure gave instructions for taking IR measurements while at . elevated temperatures during the test, this apparently was not done until after the chamber had cooled. (Tab F1, Table 7). Therefore, the only way to establish an IR value for the LOCA temperature is to evaluate the voltage shift measured during the LOCA test. One approach is to reason that the 40 mV and 6 x 10' ohms acceptance criteria correlated a 4 mV shift (representing 1/10 th of the acceptance criteria) which should translate into a lead-to- case IR value approximately ten times that of the IR acceptance criteria, or 6 x 10' ohms. Using the mathematical approach given in Calculation I-88-0003 (Reference 13) and the 4 mV shift value from the test, a leakage current of 0.004 V/500 ohms = 8 x 10-' amperes. Tab F. Appendix A, page 2 indicates the voltage potential between leads was 40 volts. Insulation resistance is then 40 V/8 x 10-8 amperes = 5 x 10' ohms, which agrees closely with that determined above.
Mglorida DESIGN ANALYSIS / CALCULATION r!! Crystal River Unit 3 Sheet 13 of _Q.9 DOCUMENT tDENTiHCADON NO. HEVISON HEl/MAHf $P NUMBER / FILE 192-0008 1 SP95 - 0002 Since the data does not indicate when the maximum 4 mV shift occurred, it is reasonable to assume that it occurred at the maximum seal temperature (due to the nature of IR). According to page 19 of Appendix A (Tab F) of the VOP (Reference 19), the specimen test chamber temperature was held at 320 *F for 8 hours whereby the conduit seal device would have experienced the same ambient condition. Therefore, a reasonable estimate for an IR va'ue at 320 F for the seal is 5 x 10' ohms. This value along with the other component IR values will determine the magnitude of the total circuit IR error such that it can be neglected from consideration in the loop error calculation for the low pressure initiate condition.

- 34. The NRC has accepted instrument error calculations based upon a 2 sigma confidence level via R.G.1.105 (Reference 47). Per the I&C Design Criteria (Reference 1), published instrument errors are usually expressed at a confidence level of 3 sigma, unless otherwise indicated. That philosophy should be valid for error terms which pertain to equipment operated in a controlled environment. However, for equipment which must survive the environmental effects of an accident (LOCA, HELB), that philosophy cannot be adhered to. The reason for such is that special environmental testing to quantify the temperature, pressure, and radiation effects due to accident conditions are usually done on too small a sample to represent a 3 sigma value. Therefore, environmental error terms shall be considered as 2 sigma values unless otherwise indicated. This calculation does not convert any 3 sigma non-environmental error terms (i.e. reference accuracy, drift, etc.) into 2 sigma terms when it combines the non-environmental with the environmental terms. This approach adds conservatism to the end result.

- 36. In the determination of the low steam generator pressure initiate and isolation setpoint, the calculated setpoint must be high enough to initiate main steam / main feedwater isolation on a depressurized condition in either steam generator. Also, at the same time actuate the emergency feedwater system. This same value must be low enough to avoid isolation of a steam generator during plant operation that is not indicative of a depressurized condition. FSAR Chapter 14.2.2.1 (Reference 3) describes the depressurtzing condition occurring at 600 psig.
[ Note: In the original setpoint calculation as documented 'n FPC Calculation I-84-0005 (B&W Document ID 51-1153083-02) [ Reference 9] this low pressure initiate point was identified to occur at 585 psig. This pressure trip point was based on a Safety Analysis for Midland I and il J.
- 37. The permissive for bypassing the EFIC trip setpoint must be accomplished when the main steam pressure decreases below 750 psig in either generator and before reaching the low pressure initiate setpoint of 600 psig. The low pressure bypass permissive can be bypass whenever one of the two main steam pressure transmitter's input has reached the pre-determined bistable setpoint. One permissive bypass will trip the other regardless of the other pressure signal level. The lowest of the two input pressure signals will also be the first to actuate the low pressure initiate bistable. The setpoint condition must ensure operator initiation of emergency feedwater in order to produce results that are bounded by the accident basis analysis [or safety analysis). During controlled plant start-up the steam generator bypass permissive bistable automatically arms itself. Reference 53 is the source document which explains the determination for the acceptability of the 750 psig bypass setpoint. In addition, the setpoint must not interfere with plant start-up and cooldown without causing spurious actuation of the EFW system.
- 38. Determination of the ADV pressure control setpoint dictates the controlled relief pressure for managing the main steam line header pressure. The selected setpoint must not challenge the main steam code safeties and at the same, avoid unnecessary release of mass energy (steam) up the vent stacks to atmosphere during normal operation. According to improved Technical Specification paragraphs B3.7.1 and SR 3.7.1.1 (Reference 2), both mention that one safety relief valve on each ste m generator has a lift setpoint of 1050 psig ( t 3%). An administrative limit of 1050 psig is in place on valves MSV-33, MSV-34, MSV-35 AND MSV.

Calculation I-84-0005 (Reference 9) assumes 150 psid with 12.38 psi error. The setpoint ensures that automatic isolation of emergency ;
feedwater occurs to a depressurized steam generator for varying sizes of steam line breaks. : l

HEVISION H61/ MAA/SP NUMBER iFILE 192 4008 1 SP95 - 0002 The above environmental conditions will now be discussed as to their impact on various transmitter accuracy components (i.e. temperature, insulation resistance on the circuit, steam pressure / temperature, and radiation),
- a. Normal Environmental Conditions The only effects considered are the transmitter temperature effects created by the differential temperature between the transmitter's calibration temperature and the normal operating temperature in the Intermediate BuHding. IR is not a concem since there is no steam environment and no high temperatures present to reduce insulation resistance. As explained in Dl7.4, radiation effects are not a factor for the normal operating environment.
EO Zone 16 lists that for a 5 hour duration period the zone is expected to experience an ambient temperature change between 129 F and 1350F. This 5 hour variation in ambient condition could be attributed to a plant upset event that results in the lifting of the main steam code safeties. The mass energy release through the 16 code safety vent stacks can create an immense amount of heat energy that is radiated to the surrounding area to cause an increase in the ambient temperatures. This 5 hour duration will be considered as an infrequent occurrence and have minimal impact on the transmitters since they are located below the discharge point of the code safeties to the vent stacks. Therefore, the transmitter wHI not be exposed to a surrounding ambient temperature (normal) of greater than 130 F.
- b. Environmental Effects Prior to EFIC - Low Pressure / Differential Pressure Actuation Followina HELB.
The FOGG Logic Assessment (Reference 52) had examined a wide spectrum of main steam line break cases in order to assess that sufficient differential pressure existed between two steam generators for FOGG to function. The assessment concluded that given a main steam isolation vdve signal (Iow pressure initiate) adequate differential pressure between the two generators was distinguishable to cause a FOGG to occur. A review of the steam line break curves in the assessment document (Reference 52) and the FSAR Figure 14-26 (Reference 3) showed that an affected steam generator can depressurize to 600 psig anywhere between one second to 30 seconds (30 seconds being worse case) depending on the steam line break size. Since there is a thermal lag associated with the transmitter, the transmitter intemals will not reach the HELB Intermediate Building temperature of 417'F (as per EO Zone 16) before the main steam low pressure actuation is reached. Rosemount conducted a thermal response test of the intemals of its 1153D transmitter (using the same stainless steel housing as used on the subject transmitters) and found the thermal time constant to be approximately 4.8 minutes (Attachment 18). In addition, a letter from Rosemount allows the use of this data on 1154 Series H transmitters (Attachment 18). Using a lumped system analysis approach to heat transfer, a transmitter intemal temperature at the time of main steam actuation can be derived. This method provides good results whenever the intemal conductive resistance is small compared to the extemal convective resistance. Whenever this is true, the temperature of the object wHI be spatially uniform at any given time. Rosemount used this approach in Attachment 4 to determine transmitter intemal temperature as a function of time. Usirs the approach given in Attachment 4, the transmitter intemal temperature can be derived 30 seconds after the HELB occurs. As long as the time constant of the transmitter is much larger than the time to EFIC - low pressure, the IB temperature rise can be treated as a step change. This does add conservatism since a higher intemal temperature will result. Therefore, using the lumped system neat transfer analysis method, the intemal electronic temperature can be determined at the low pressure initiate (along with deltaP) using the equation from Attachment 4 will be: , 55 FA DiI

= 130'F + 28.36*F
= 158.36* F
= 158'F (Temperature rounded down)
As determined, the transmitter's electronic intemal temperature has not heated-up to the surrounding HELB temperature and actually lags it. This, then shows that the transmitter's temperature effect is stBI within Rosemount's normal operating design limit of + 40*F and 200*F (DI #7). Therefore, the normal temperature effects will be used in the determination of the transmitter inaccuracy for the low pressure and differential pressure loop errors. During the actuation period the instrumentation cable, conduit seals and splices are exposed to the same elevated environment as the transmitter and a certain magnitude of IR may have an influence on the loop error. As with the transmitter, there is a thermal lag associated with these devices. Rather than performing a rather rigorous finite element thermal analysis on each device to determine its approximate temperature at the time of actuation, the above lumped parameter approach will be used for each device in order to show that the combined IR's have a negligible affect and therefore need not be considered in the calculation of the loop error. Design input (DI) #21 states that thermal lag of multiconductor cable is typically about 3 minutes for those mentioned in SAND 89-1755C. According to the report , this 3 minute period was the time it took for the cable to reach a stable value of IR. The report does not cover how many time constant this cteady state constant represents. Assuming this 3 minute represents 3 time constants, one time constant would equal to 60 seconds. This time constant should be conservative since the cables were not tested in conduit. The main steam pressure transmitter instrumentation cable gre routed in conduit. The conduit provides an additional thermal resistance to cable temperature increases and would thus increase the actual thermal time constant of the cable (i.e. reduces the cable temperature). Using the 60 seconds as a conservative thermal time constant, the following cable, temperature at the time of the low pressure actuation can be determined using the same lump systems analysis approach: Tu = 130*F + (417'F - 130*F)[1 - exp(-30s/60s)]
= 130*F + (287'F)[1 - exp(-0.5)]

130*F + (287*F)[1 - 0.6065]
= 130*F + 112.93'F

The IR value listed for this temperature is 1.7 x 10' ohms. According to Tab 14 of VOP TERM-R09844 (Reference 20), Raychem has not published data regarding thermal lag through its WCSF-N splice sleeving; however, contained within Tab 14 are results of laboratory testing done on a sample of WCSF-200 material. From those test results , a thermal time constant for the main steam actuation period (0 - 30 seconds) based upon the inside sleeve temperature will be determined using the same lumped systems analysis approach established earlier: 90*C = 50 + (225'C - 50 C)(1 - e-nge) 40 C = 175 C - 175'C [eencj

= 164.93'F From VOP TERM-R098-04 Table 1 (Reference 20), the closest splice temperature that matches the above calculated value is listed as 210 F. The IR value listed for this temperature is 4.6 x 10' ohms.
No thermal time constant information is available for the Rosemount conduit seals used at the transmitters: therefore, it will be conservatively assumed that the seal has the same thermal time constant as the cable. This should be conservative since the seat is an extension of the cable and more dense than the cable. From this assumption, the transmitter seal temperature at low pressure initiation is assumed to be the same as the cable temperature of 243.93 F. Refering to Design Input (Dl) #23, the IR value was defined for our condition as 5 x 10' ohms.

For conservatism, where conformity Oinearity), hysteresis and/or repeatability values are equal to or greater than the specified accuracy, then the value(s) will be combined via the SRSS method with the specified accuracy term to determine the Reference Accuracy value.

V. DETAILED CALCULATIONS This calculation will evaluate the instrument loop accuracles associated with the main steam pressure transmitters (MS-106-PT through MS-113-PT) during Normal and Accident (HELB) conditions. COMPONENT ERRORS: Process Error: Per Design input (DI) #2, the majority of the sensing lines associated with MS-106-PT and MS-113-PT are routed within EO Zone 16, which has the following temperature ranges: Temperature - Normal: 80* to 135'F. Temperature - LOCA: The same as normal. , Temperature - HELB: 149' to 417 F. Sealed Reference Lea. Per Design input (Di #7.7), there is a need to examine the effects due to a sealed reference chamber not at existing atmospheric conditions. i The main steam pressure transmitters are calibrate on site utilizing a gauge pressure test instrument. The l measurable atmospheric conditions at Crystal River Unit 3 are between 28 to 32 inches of mercury (13.75 psi ! to 15.77 psi) according to Reference 60. Since the transmitters are calibrated on-site and the atmospheric conditions vary between 28 to 32 inches of mercury (13.75 psi to 15.77 psi), then the maximum error due atmospheric pressure fluctuation at CR-3 resulting in transmitter inaccuracy reading is: (32 - 28)(0.4912 psi /in Hg)/1200 - 1.64 x 10 = 0.164% error i i m on

REvissON RElj MARj 5P NUMBER, HLE 192-0008 1 SP95 - 0002 This variation in atmospheric condition causes a 0.00164 error in rm ent which has an insignificant affect when compared to the magnitude of the ery 3 - M by tranmitter reference error inaccuracy of t 0.25%. Therefore, process measurement o due to the sealed reference leg will be considered as negligible and have no effect on the loop string error. Transmitter Scalina. The eight main steam transmitter sensing line configurations have their process connection routed off the top of the main steam line header and connected to the transmitter below the steam line tap connection. This configuration allows the sensing line to be filled and prevents contact of live steam with the transmitter. This configuration can be viewed as a manometer where the reference datum is the center line of the transmitter and the column of water above the datum will represent the applied static pressure. The water in the sensing line of the pressure transmitter is at the same temperature as the intermediate building. Per the EO Zone Sheet 16, the area can vary from 80 F to 135*F but a good portion of the time (32.2%) the area experiences temperature conditions of 120 F to 124'F, therefore 124*F will be used as the normal sensing line temperature. The normal operating pressure of the main steam line is 900 psig. The change in elevation between the tap connection on the main steam line and the reference datum is 20 inches (or 1.67 feet) which is typical for all of the transmitter locations. With the interpolation of the data from Table 3 of the ASME Steam Tables (Reference 70), the specific volume of water at 124'F and 914.7 psia (900 pisg) is: 130 F = 0.01620 ft'/lb,,, 124 F = x 120 F = 0.01616 ft'/lb, 4oF/10 F = x/0.00004 ft'/lb, x = 1.6 x 10-8 ft'/lb,,, At 124 F the specific volume is 0.01616 + 0.000016 = 0.01618 ft'/lb,,,. Thus, the weight density is 61.805 lb,,,/ft* (1/ 0.01618 ft'/lb,,,) and then the following correction is necessary for calibration of the transmitters: 1 (61.805 lb,,,/ft') (1ft2 /144 in') I
= 0.429 lb ,/in'-ft (0.429 lb,,,/in'-ft)(1.67 ft) = 0.716 psig This scaling correction adjustment to the transmitter is outside the calibration limitations of the Druck which has an ability to accurately calibrate within the tolerance of 13.87 psig (Reference 41). Therefore, process measurement due to transmitter scaling will be considered as negligible and have no effect on the loop string error.
So then, TRANSMITTER SCALING e o psig'(0.00 %) to 1200 psig (100%). Sensina Line. The HELB temperature in the intermediate building peaks at 417 F where this temperature value will be used to determine the maximum error due to density changes in the sense line.

Per Table 3 of the ASME Steam Tables (Reference 70), the specific volume of water at 417 F and 914.7 psia (900 psig) must be interpolated between 0.01886 ft*/lb,,, (at 420 F and 900 psla) and 0.01871 ft*/lb,,, (410 F and 900 psia). Therefore, the 3 weight density is between 53 02 lb,,,/ft* and 53.45 lb,,,/ft'. For conservatism, a weight density of 53.02 lb,,,/ft will be selected for this calculation. I The change in pressure for the sensing lines of the pressure transmitter is related to the change in sense line density as follows: l AscuseuNr = {I(dra - dr,) / (144 in8 /1 ft')] x (L/ Span)} x 100%

Per Design input (DI) #30, the 'As-Left' tolerance currently used in SP-193A for the Control Room Recorder Indication (MS-110-PIR and MS-111-PIR) is : 15 psig.

Per Design input (DI) #31, the current setpoint used in SP-146A for the low pressure initiate bistable (MS-106-PS1 thru MS-113-PSI) is 617.76 psig. As can be seen the calculated low pressure initiate setpoint is greater than the current assigned setpoint setting in the bistable. Considering the existing setpoint of 617.76 psig and subtracting off the calculated 'As-Found" tolerance of 16.34 psig results in a lower 'As-Found* setpoint limit of 601.42 psig. In comparison with the improved Technical Specification (ITS) limit of 600 psig, the lower "As-Found" limit of 601.42 psig is 1.42 psig above and still assures that the iTS limit is not violated during surveillance testing. The current setpoint complies with assuring that the iTS limits aren't violated but, using the current in-plant setpoint causes the calculated loop error to shift the analytical limit below it's present value of 585 psig by 6.55 psig (578.45 psig). This is unacceptable and therefore, Low Propure initiate SetpoinrF824.5lpsig Now that the low pressure initiate setpoint has been established, then this value must now be adjusted into the EFIC bistables in each of the cabinets (MS-106-PS1 thru MS-113-PS1) in order for the EFIC Control ) system to cause main steam and main feedwater isolation along with starting the EFW. To adjust this setpoint value into the bistable we must change the setpoint Jack per the instructions outlined in the Vitro instruction Manuni (Reference 36) on page 6-21. The manual instructions provide us with an equation on how to determine the desire pressure setting in terms of a voltage setpoint as follows: Low Pressure Bistable Setpoint Voltage = [ (P) x 3.333 mV ] + 1.0 Volt

, The SG pressure bypass setpoint is determine in the following manner: First, using the low pressure initiate setpoint as the lowest bound limit for the bypass permissive, we find that the; Minimum Setpoint = Low pressure setpoint + CE.
= 624.50 psig + 26.76 psig
= 651.26 psig
= 651 psig (Setpoint rounded down for. ease of setting)
Maximum Setpoint = FSAR Value + CE.
= 750 psig - 26.76 psig
= 723.24 psig
= 723 psig (Setpoint rounded down for ease of setting)
Choosing the minimum setpoint does not provide adequate margin above the low pressure setpoint to avoid spurious trips resulting from a main control board operator's inability for lack of time to bypass the trip feature. Selecting the maximum setpoint gives the operator increase margin (723.00 psig - 624.5 psig
= 98.5 psig) for bypassing the low pressure condition. Also, the maximum setpoint maintains the differential pressure between the SG's in order to distinguish the depressurtzed one and isolate it.
Therefore, the maximum setpoint is selected. l Per Design input (DI) #31, the current plant setpoint used in SP-146A for the permissive bypass bistable l (MS-106-PS3 thru MS-113-PS3) is 732.37 psi. As can be seen the calculated bypass setpoint is lower than the current assigned setpoint setting in the bistable. Considering the existing setpoint of 732.37 psl and add;ng the calculated 'As-Found' tolerance of 16.34 psi results in a high 'As-Found* setpoint limit of 748.71 psi. In comparison with the improved Technical Specification limit of 750 psig, the high 'As-Found" limit of 748.71 psi is 1.29 psig below and still provides assures that the ITS limit is not violated during surveillance testing. Therefore, the current permissive bypass setpoint as listed in SP-146A as 732.37 psig is acceptable l and complies with assuring that the limits don't violate the ITS requirements. l fW}M %E732.Rpaid Now that the bypass permissive setpoint has been established, then this value must now be adjusted into the EFIC bistables in each of the cabinets (MS-106-PS3 thru MS-113-PS3) in order for the EFIC Control system to avoid actuation of the low pressure trip on normal plant cooldowns. To adjust this setpoint value into the blstable we must change the counting dial per the instructions outlined in the Vitro Instruction Manual (Reference 36) on page 6-19.

Maximum Setpoint = FSAR Value - CEop ,
= 150 psid - 55.21 psi
= 94.79 psid
= 94.5 psid (Setpoint rounded down for ease of setting)
Now determine the minimum setpoint which prevents isolation of a non-leaking /depressurized steam generator which is based a zero (0) differential across both steam generators at operation. Minimum Setpoint = Steam Generator dP + CE os .
- O psid + 55.21 psi
= 55.21 psid To prevent inadverent steam generator Isolation the maximum differential pressure setpoint is selected.
Per Design input (DI) #31, the current plant setpoint used in SP-146A for the steam generator differential pressure bistable (MS-106-PS2 thru MS-113-PS2) is 106.80 psid. As can be seen the calculated differential pressure is less than the current assigned setpoint setting in the bistable. Considering the existing setpoint of 106.80 psid and adding the calculated "As-Found' tolerance of 22.69 psi results in a higher "As-Found" setpoint limit of 129.49 psid. In comparison with the improved Technical Specification limit of 125 psid, the higher limit of 129.49 psid exceeds the ITS limit. Therefore, the existing steam generator differential pressure bistable will need to be changed to 94.5 psid. SG Differential Pressure Setpoint = 94.5 paid Now that the differential pressure setpoint has been established, then this value must now be adjusted into the EFIC bistables in each of the cabinets (MS-106-PS2 thru MS-113-PS2) in order for the EFIC Control system to achieve the FOGG logic function.

A. l 3.0 ANALYSIS, The 1153 series D transmitter is virtually identical to the 1153 Series B transmitter. The only differences are: 1) the use of an clev. /supp. switch vs. jumper wires, and 2) different electronics housings. The 1153 Series B is intended for BWR applications (and out-of-containment PWR applications) and has an aluminum housing. The 1153 Series D is intended for PWR applications and has a stainless steel
; housing. Functionally, they are identical, therefore, the 420 F temperature test performed on the 1153 Series B will provide the basis for justifying a 420 F temperature spike for the 1153 Series D.
A test was setup to expose seven 1153 Series B transmitters to superheated steam at 420 F for 3 minutes. The transmitters had previously been exposed to 24.4 megarads , gamma radiation and two steam temperature / pressure tests typical of a BWR. Radiation shielding for stainless steel is about twice the value for aluminum, therefore 24.4 megarads on an aluminum housing is approximately equivalent to 50 megarads on a stainless steel housing. ,

The temperature transient from room temperature to 420 F took approximately 1 minute to achieve. During the test, chamber i pressure was in excess of 115 psig for more than two minutes. ( Throughout the test all seven units continued functioning and the maximum errors were within the present LOCA specification of + 8.0% of upper range limit. Since the electronics hcusings are different, the temperature offeet on the electronics must be determined separately. During the 1153 Series a test, the maximum average electronics board temperature was 326 F. (Ref. 2.1). Since the electronics in the two models are identical, test results will be identical if the 1153 Series D electronics board does not exceed 326 F. The time constant for the stainless steel housing used on the y 1153 Series D is approximately 4.8 minutes. (Ref. 2.3).

Any errors introduced by the various stages are detected and corrected by the subtractor (error oetection) stage.

Dear Mr. Seay:
The following clarifications and modifications are required to the j EFIC Equipnant Specification 08-1123896-01.
- 1. Specification paragraph 6.5.2.A requires 10.25% isolated anslug circuit accuracy. The multiplexed analog isolation scheme previously developed for B&W equipment and proposed for the i EFIC eqidpment is capable of an accuracy of 10.5%. This was i reported to Mr. Al Lloyd of B&W on March 11, 1982 who stated that the 20.5% accuracy was adequate and agreed to take
- appropriate action.
- 2. Light-Emitting-Dioden located in the EFIC to annunciate test confirmation signals, will illuminate continuously if the full complement of test confirmation signals is present; will flash if one or more but icss than the full complement of test rceults is presents will not illuminate if no test confirmation signals are present. This is in accordance with specification paragraphs 5.4.5.I and 5.4.5.J. However, specification para-graph 7.5 states " Lamp failures shall be self-indicating unless justificd by the Vendor." As presented above, the specified functional operation of test confirmation indicators is not compatible with the self-annunciating f ault requirements of ,
paragraph 7.5. therefore, the test confirmation indicators are hareby requested to be exempt from the requirement of para- a graph 7.5.
+ 3. Specification drnving 1122948, Logic 12. depicts a time delay l utilized in transfers T2, T3 and T7. No time delay adjust-ability range or accuracy is specified. Therefore, Vit ro will previ.la adjustrc. cat from 1/64 of a second to 64 scconds and an accuracy compatible with the accuracy requirements of the Control Module. .

Dear Mr. FitzGerald:
In March of 1983, C. E. Suer furnished a letter (VL-CS-T-75(83) dated 03/31/83; copy attached) to Babcock & Wilcox which described the error inaccuracies for the compensation and control modules. The information on the letter was used in the development of instrument loop string error calculations. Presently, our instrument loop accuracy calculations are being expanded to include other functions of the cabinets which were not addressed in our initial design. Especially those concerning the Non-lE analog isolated outputs. B&W design specification 08-1123898-03, paragraph 6.5.2, page 33 requested that these signal isolators have "an accuracy available at the Non-lE side with respect to input shall be 10.5%, worst case ". Was this specified accuracy meet or exceeded? Since the above mentioned Vitro letter did not cover the " analog isolation input (part no. 3801-1024) and the analog isolation output (part no. 3801-1030) modules, is it possible for Vitro to supply the same type of information as previously given either on a module level or on an individual sub-component level. If given for the modular sub-component level, only those IC's that take the analog signal and convert it to a digital output; and then convert it on the other side of the AIO. Also, is there any error inaccuracy associated with the IE to Non-lE digital isolator's which are part of the loop string between the analog input and analog output isolators. Your assistance in this area will be greatly appreciated and help my efforts in ) completing the necessary instrument string calculations.

, Under these conditions and assumptions. RC system thermal .
expansion calculations estimate the time to lift the pressurizer ,
~
code safety valves at 5.1 minutes and the time to fill the pressurizer solid at 12.0 minutes. ' 2.2 Simulator , Since the calculated times are close to the 10 minute operator action *e criterion, and, since the calculational method is simplistic in nature, a corroborative method was desired. The 88W simulator was determined - to be an expeditious way to provide such a check. Some conditions ,' , for the simulator run were slightly different than for the calculations. i

In addition, work was done on the VEPC0 plant (see Reference 4) which also showed that under certain conditions it is possible for the intact loop not to repressurize even for a large steam line break. In order to avoid the problems mentioned above, it has been suggested that the FOGG logic be modified to include a differential pressure measure-ment.. The modification would cause AFW to be terminated to one S.G. in a case in which both steam generators were belov 600 psia and the pressure difference between the generators were greater than 150 psi. If these conditions exist FOGG would direct AFW flow only to the higher pressure steam generator. The purpose of this analysis was to: (1) Detemine whether the proposed modification to FOGG would cure the known problems. (2) Identify any other possible scenarios which still would result in FOGG's inability to detamine which was the intact loop (e.g., a case in which steam generator pressure difference is less than 150 psi), and (3) Assess the consequences of any cases found under (2) above.

Dear Mr. Iwachow,
The Rosemount model 1154 Series H transmitter Drift Specification is published rs 10.20% URL for 30 months. This specification will be included in aR future revisions of Instruction Manual MAN 4631 and product literature PDS 4631. Older revisions of model 1154 Series H transmitter product data sheets and instruebon manuals indcated a drift specification for only 18 months. The reason was due to the pubile.ation data. When these documents were published, the drift specification test conducted by Rosemount to develop the 30 month specification was not yet complete. The 30 month drift spedf-+0en is based on a 36 month drift test completed by Rosemount. The results of the testing is published in Rosemount Report D8900126. Although the title of the report states applicability to Model 1152.,1153, and 1154 transmitters, this data is applicable to all Model 1154 Series H transmitters by similartty. The Model 1154 Series H Transmitter utilizes the same Electronics Package and Sensor Module as the Model 1154 transmitter. Although there are differences 'm the physical design of the two model types, there are no differences between units which impact drift. Therefore, the results of the Drift Specirmation testing is directly applicable to the model 1154 Series H by similarity. Sincerehr T. J.

ROSEMOUNT REPORT 78212. I-l- 1.
SUMMARY
Several previous reports have been written on the thermal response of Rosemount nuclear qualified and related transmitters to the temperature transients expected in a High Energy Line Break (HELB) accident (see refs. 2.1 through 2.6). However, none of the previous tests were conducted using high energy steam as the heat transfer medium. This report summarises the results of recent tests of the internal temperature response of Rosemount Models 1153 Series B and Series D pressure transmitters when exposed to sudden high-temoerature steam impingement. s

The tests, described in ref. 2.7, were conducted in Rosemount's Steam chamber (ref. 2.9). As part of this test, a non-operating unit was placed in the chamber. It contained a thermocouple located on one of the screws holding the amplifier board in place. Since the amplifier board contains most of the sensitive components of the unit, the :
thermocouple readings give a good indication of the effect of external temperature transients on the unit. A test series was subsequently run using the Rosemount Model 1153 Series D transmitter, which uses a housing made of 316 stainless steel. A similar non-operating unit with an internal thermocouple was used, and the output recorded during a simulated HELB transient to 350 F. The temperature inside the chamber, as determined by thermocouples placed close to the test housings, rose from room temperature to the desired temperature within approximately 30 seconds. i

A more precise analysis, however, can be made using a technique (called Step Analysis) described in ref. 2.8. The response of a one-time-constant system to a step input is given by 1-exp(-t/ 6 ), where t is elapsed time and 6 is the time constant. If the response is calculated in terms of the percentage of the step response which has not yet appeared inside the system (t incomplete), this exponential function yields a straight line on semi-log paper, with the line intersecting t=0 at 100 % incomplete response. In a multi-time-constant system, however, a graph of 4 incomplete response vs. time will show a deviation from a straight line initially, with the data more closely resembling a straight line as time increases. A straight line through the data at large time values, when extended back to t=0, represents the time constant of the slowest responding thermal element of the system. This is shown by the solid line in fig. 2. The i time constant of the slowest element can then be determined by noting the intersection of this line with t=0 (130% in l this case), calculating the point at which this line would be 36.8% incomplete (=63.2% complete) , and finding the time along the line at which this response would occur. The calculation shown on fig. 2 gives 4.8 minutes, which is very I close to the 5 minute value determined from fig. 1. A calculation of the time constant of the next-slowest thermal element can be made by plotting the difference between the 6 , - 44* .1 I
t ANALYSIS / CALCULATION i Doc to # I-97 oco8 ATT * (& REV I SHEET 9 OF 14 unit's response and the straight line extrapolation. This is shown by the x's in fig. 2, with the dashed line being a straight line extrapolation through these points. The points follow a straight line all the way to t=0, so there are no other significant thermal elements involved between the steam i outside and the amplifier board inside the housing. A calculation of 36.8% incomplete time on this line results in a second time constant of 1.4 minutes.

Fig. 3 shows the steam temperature input and response of~ the > thermocouple inside the aluminum 1153 Series a housing, as replotted from ref. 2.7. The step function was held for only ; about 5 minutes, which is not long enough to plot a reliable ; time constant value from this graph. However, the Step i
~
Analysis technique, shown in fig. 4, still works. In this case, the Step Analysis technique must be repeated twice, ! resulting in calculated time constants of 3, 1.2 and 0.6 i minutes. The 1.2 minute result here agrees quite closely with the 1.4 minute result of fig. 2. This indicates a common thermal element, probably the standoffs on which the amplifier board is mounted. The first time constant in each , ,, case is obviously due to the housing, resulting in a thermal time constant of 4.8 minutes for the Series D and 3 minutes , for the Series B.

l ANAL (SIS / CALCULATION DOC !D # I 91 ooo8 ATT # 18 REV l SHEET to OF I4 the Model 1153 Series D is approximately 4.8 minutes. The time constant of the aluminum housing of the Model 1153 Series 3 is approximately 3 minutes. Although postulated HELB events usually specify a rise time of 10 seconds from room to HELB temperatures, this data shows that slower rise times can be used during testing without affecting results, as long as rise times are short compared with housing response. Thus, a 30-second rise time (16% of the time constant of the fastest unit) is an acceptable simulation, since the internal components see the same transient. Previous tests with very fast rise times, such as described in ref. 2.5, prove qualification of the external part of the housing for 10-second rise-time HELB events. e ' Y A .m *

The ADV control circuitry was housed modular cards which occupied cabinet positions 4-4-3 and 4-412 (Reference 50). The control function was removed from ICS and transferred to the EFIC control logic. Since no operational occurrences were experienced or identified with the ICS control valve tuning parameters, these same parameters were set-up for the EFIC control logic. The following tuning parameters as transferred from ICS and translated to binary setting for placement on the front panels of the EFIC control modules for the pressure control function (MSV-025-PC and MSV 026-PC). a) Translation of Intearaf Rate. Previously, ICS module 4-4-3 had an integral setting of 2 repeats / minute. To adjust this rate into the front panel, we set the 5 digit thumbwheel switch per the Instructions outlined in the Vitro manual (Reference 36) on page 6-16. To match the EFIC setting, the ICS values must be converted as: A = B/60 where B = the ICS setting of repeats / minute A = the EFIC setting of repeats / seconds So then, the setting for the ADV repeat /second is 2 repeats / minute or A = 2/60 A = 0.0333 the thumbwheel setting should be as100333 ", b) The Procortional Band. The proportional band setting in the in ICS module 4-4-12 had a " K " setting of
- 5 ". To adjust this rate into the front panel, we set the digit thumbwheel swltch per the instructions outlined in the Vitro manuel (Reference 36) on page 616.
To match the EFIC setting, the ICS value of ' 5
- is set as: ADV K!'{06000 000 671 0/ta}}
