REPORT CSR090. PAGE 2. 1.0 PURPOSE The purpose of the work described in this report is to determine the Eh11 "htargin of Immunity" for installation of the SRV Electric Lift system. Specifically to susceptibility of portable transmitters (walkie-talkies) with operating frequencies ranging from 450-900 hiliz operating at an output power of.6 - 5 watts when operated in the local equipment area. 1.1
SUMMARY
of EVALUATION 1.1.1 Summary Susceptibility testing performed by the vendor meet or exceed criteria established in the Guidelines for Eh11 Testing, EPRI document TR 102323. The margin of immunity at " Point of installation" was confirmed to exceed 30 dBpA by direct i measurement of common mode coupling at the 1/O, power input and ground cables l to PAM 103 and PAM 104 panels (Foxboro rack). 1 Transienis initiated were a function of keying "walkie-talkies" of different frequency and power output capability at various distances from the PAM panels. 7 Actual radiated E-field measurements were calculated (see table 3 and attachment 1), and coupling levels were measured as current using the CllAR 921 system with the DSO in peak detect and a long sweep rate. This technique ensures measurement of maximum amplitude transient response for the cables interfacing with the SPEC 200 Micro control system. It is also very conservative and provides more realistic results of field conditions since actual cable type and lengths are used to determine system response and not simply estimated as in Test Lab performance. The SRV Electric Lift circuit remained stable, and was unaffected by intentional transients initiated in the PAM room, as well as random transients which were also captured during testing. The only exception to this was a single test where the whip antennae of the 3 watt 850 Mllz walkie-talkie was placed in direct contact with and across the face of the wide range transmitter cover PT-263-114. Keying the transmitter resulted in the actuation of the CRP 903 "SRV Electric Lin St Off Normal" and "SRV Electric Lin Initiated" alarms in the control room. Calculations show that the e-field at the point of contact (transmitter) exceeded 116 V/M The transient measured at the input to the PAM panel was 78dBpA, with an envelope bandwidth greater then other measured transients by a factor of two. This final test was more severe (by a factor of almost 12) then that recommended by the TR-102323 guidelines and is not considered a potential threat, since the transmitter rack is a radio transmitter exclusion zone and with just I meter of spacing the induced noise was attenuated below the response of the system. mmrum sumcrs, nc.

The random transients measured were believed to be a result of welding at a remote location, hiaximum amplitude, measured pk to-pk fbr all transients was less then 87dBpA common mode with envelopes typically lasting less then 15 ms. Although outside the scope of this report, it was noted that the I)rywell Ilulk Temperature Thermocouple circuits which also have input to the PAh! paneis are very sensitive to the radiated E-field of the walkie-talkies and responded with varying temperatures and even alarms in some cases when the panel doors were open. This was not unexpected by CllAR Services', as our experience has shown this type millivolt response circuit is very sensitivity to Eh11. 1.2 Description of SRV Electric Lift ControlSystem The SRV Electric Lift Control System consists of a SPEC 200 NilCRO system manufactured by the Foxboro Company. This system is self-contained in its own equipment rack and is being installed in the PAh! Room. ! The following modules make up the total system:
. 2Al 12V SPEC 200 CONVERTER
. 2AO-L2C-R SPEC 200 lSOLATOR j . 2AO-val SPEC 200 CONVERTER e 2ARPSOS SPEC 200 POWER SUPPLY
. 2CCA SF&DF SPEC 200 MICRO CONTROL CARD The SRV electric lift system will receive analog input signals for pressure from:
. PT287 112 (RX pressure transmitter narrow range )
. PT287-113 (RX pressure transmitter narrow range )
. PT263 114 (RX pressure transmitter wide range )
. PT263 115 (RX pressure transmitter wide range )
It functions to supply the actuation signal to a pilot valve which will enhance the operation of the main steam safety valve by supplying additional air to unseat the main steam safety valve in conjunction with actuation demand. Incoming and outgoing signals are carried on twisted shielded pair insulated wires (cables), with an overall protective jacket. All incoming signals have the shields directly grounded to the SPEC 200 hilCRO system vertical ground bus within the PAh! panels (103 and 104). Outgoing signals have the shields grounded at the DAS 941 computer panel. In both cases input and output are separated with single point grounds , minimizing the potential for ground loops to develop. Additionally cables entering and exiting the PAh! room and PAh! panels 103 and 104 where the SRV system SPEC 200 micro modules are located are routed in conduit. All of these are ferrous metallic.

REPORT CSR090. PAGE 4. 1.3 Findings General The major safety concern for operation of the SRV electric lin circuit is a common mode failure that would affect both redundant system SRV's at one time. Becau of the relatively low power level of the radio transmitters tested, CilAR considered that the disruptive signal would have to arrive simultaneously on all redundant systems and cause a response detrimental to safety. The transmission path from transmitter to sensitive, redundant system would have to be either radiation through space, or conducted on RF transniission lines from the emission point to the redundant systems. CilAR considered that a response detrimental to safety would be loss of control of a plant parameter or critical system. CllAR considered that an alarm trip due to a single channel in a safety , tmin, but which did not activate the safety system, would not be considered detrimental to ! plant safety. With this assumption, the only critical scenario is one in which the l transmitter is brought within a critical exclusion zone of redundant safety systems. During ! testing this critical exclusion zone was identified as the transmitter rack 2206 with the whip antennae placed in direct contact with and across the face of the wide range transmitter cover PT 287-Il4. In this configuration, operation of the 3 watt, 850 Mllz walkie-talkie resulted in the actuation of the CRp 903 "SRV Electric Lift Si oft normal" annunciator and "SRV Electric Lin initiated" Sequence of Events (SOE) alarms in the control room. This is considered a worst case condition and was not repeatable for the redundant wide range channel, PT-263 115. 1.3.2 Determination of EMI immunity level The SPEC 200 MICRO system has been tested for electromagnetic interference susceptibility as reported in Foxboro Test Report 88-1033a, dated November 30,1988. The levels to which the system was tested are summarized as follows:

REPORT CSR090. PAGE3. It should be noted that both the signal leads and power leads have been tested ihr direct effects of EMI transients where expected transients are generated directly on these lines rather than for indirect effects where such effect would occur remotely on another line and then couple to the SPEC 200 cable. This represents a severe test and eliminates any possible concern for locating and testing secondary coupling effects in the plant. 1.3.1 Margin of EMI immunity for point ofinstallation Following is a summary of the EMI immunity margins for the SRV Electric Lift. For the conducted EMI immunity, the values given are only estimates based on comparison with recommended susceptibility test levels compared to levels measured at the point of
-installation, using a characteristic impedance of 100 ohms for added conservatism.
Because these currents increase at the point ofinstallation as a function of the effectiveness of the filtering and grounding of the input conductors and/or shields, there should be little concern that the levels measured indicate any kind of EMI threat. l l EMI TilREAT AT POINT OF MARGIN OF INSTALLATION IMMUNITY HASIS 111011 FREQUENCY ACTUAL DIFF BETWEEN MIN CONDUCTED TRANSIENTS 48 dB SUSCEPTIBILITY LEVEL TEST AND MAX LEVEL DETECTED RADIATED ELECTRIC FIELD > 24 dB FOR StTE ACTUAL DIFF DETWEEN MIN WALKIE TALKIES, SUSCEPTIBILITY TEST AND GREATER TilAN 30 dB MAX LEVEL DETECTED FOR ALL OTilER SOURCES RADIATED MAGNETIC FIELD N/A- Not considered a threat CONDUCTED EMI CURRENT ON >20 dB below 15 Ulz COMPARISON WITil SIGNAL AND POWER >l3 dB above 15 kilz RECOMMENDED TEST CONDUCTORS LEVELS FROM CSil4. The coupling of the radiated signal to inadvertent antennas and the re-radiation of conducted signals into critical areas will be a function of the apparent gain of the antennas and can be analyzed as a near field problem either as the magnetic field or the electric field (IEC 1000-2-3, paragraph 3.2, page 31). In either case, there is a linear increase with frequency. The IEEE Std C95.1 uses a derating for interference severity based on the ratio of 450 MHz divided by the actual operating frequency'. Thus, the severity, relating to plant equipment susceptibility, should double when shilling from a radio operating at 450 Mllz to one operating at 900 Mllz,
'lEEE C91.5 does not really explain the use of this ratio. Ilowever, there is a direct correlation to the reactive coupling w here the capacitive coupling increases with frequency and the mutual inductance, magnetic coupling also increases with frequency. Also, in the far field, the effective height (sensitivity) of an antenna is a function of frequency..
Ol996CIIAR SERvlCl3,INC. ALL RIGIITS RESERVED.
REPORT CSR090. 1%GE 6. In dealing with equipment immunity, the interfering signal must first be picked up by an inadvertent antenna and then carried to the location of sensitive device. CilAR's conclusion from this discussion is that the conducted EMI losses will tend to offset severity increases when shifting from 450 Milz radio communications to 850 Milz radio communications and 900 Mllz cellular phone operations. In applying this to Millstone, CllAR can state that interference picked up on cables at the sensor (transmitter) end (nominally 200 feet or more remote from the PAM room) will not be expected to increase the severity level in the PAM panels. 1.3.2 Identification of EMI strengths The SPEC 200 MICRO system has a number of significant features that enhance its immunity to EMI and should be pointed out to support its performance to the above susceptibility tests that are severe for the actual operating conditions of the system. These ; are noted as part of the system walkdown using CilAR Services checklist for EMI conditions at point ofinstallation and documented as follows:
. All components are isolated, in a separate rack where the only other control panel is greater then 3 meters away and is powered from a separate 115vac power supply.
. The components that make up the system are separately packaged in enclosures that provide additional electromagnetic shielding.
. The rack and ground bus are tied together at the bottom of the rack and the ground bus extends vertically up through the center of the rack to provide low impedance connections for all incoming shields.
. Incoming analog lines are maintained as twisted pairs wherever possible to negate any near field magnetic coupling.
. The incoming and outgoing cables enter the rack through a conduit from above and this conduit is directly grounded to the panel.
. The shields for incoming analog cables are tied directly to the ground bus, acting as a short to common mode signals and causing noise spikes to be reflected.
. There are no 480vae or greater equipment located within the PAM room.
. There are no unsuppressed inductive loads (control relays) located in the PAM panels, PAM 103 and PAM 104.
. There are no RF transmitters within line of sight in the same room.
. Use of portable transceivers is controlled administratively with local signage.

REPORT CSR090. PAGE 7. 1.3.3 Summary of EMI(oncerns Selection of Susceptibility Test Levels On the basis of selection of severity levels for the interference testing conducted by Forboro, there should be no concerns for EMI. Foxboro in each case has tested to a severity level higher than required for the operating environment of the SPEC 200 system as located in the plant. Further, Foxboro has tested for susceptibility to direct injected transients, which if they occurred in normal operation, would only be expected to affect a single channel of the SRV Electric Lill circuit. Such single channel interference would not be considered a safety issue because of the two-out-of-two taken once criteria for operation of the system. 2.0 Determination of EMI Emissions levels l The following table describes the expected radio transmitter electric fields generated by various power levels at several distances from the source. An antenna gain of 1.5 is considered as reasonable for a whip antenna operating over a ground plane (site engineering provided information indicating that the antenna is lossy with an actual gain of
= .75 which adds conservatism to the effective radiated power calculations). Additionally, the gain of a portable transmitter will generally be significantly reduced because it will be operated in the vicinity of a human and this will de tune the antenna, reducing the radiated power. There would also be some absorption of the radiated power by the human body.
As long as the vitenna is more than a. wavelength away from metallic reflectors, the reflected wave would not be expected to significantly increase the gain in any one direction ,- -- mainly because the reflections would be scattered rather than focused. At 500 Mllz, the I wavelength in air is 0.6 meters; at iJ00 MHz, the wavelength in air is 0.3 meters.

See attachment 2 for details of P, calculations. 2 Refer to attachment 2 for discussion of antenna pattern, gain, and calculations. The radiated electric field is proportional to the square root of the effective radiated power, so a reduction in the gain from 1.5 to 0.75 would only reduce the radiated electric field by 0.707.

REPORT CSR090. PAGE 8. 2.1 Margin of EMIimmunity for equipment environment The EPRI Guide TR-102323 recommends that digital safety equipment to be installed in the power plant be tested to function in radiated electric fields of 10 V/m and this correlates with the general industry guidelines for immunity from radiated electric fields over the frequency range of 10 kilz to 1 Ghz. As determined by EPRI in TR-102323, the un-intentional radiation environment in a typical power plant is less than 0.07 V/m over this range while the intentional emission from portable transmitters in the 100 MHz to 1 Gilz region was as high as 10 V/m, TR-102323 recommended that the portable transmitters be controlled to create a radiated electric field no greater than 4 V/m' impinging on plant equipment. This could be accomplished in the plant by controlling the minimum distance between a portable transmitter and plant equipment when operating the transmitter and/or controlling the elrective radiated power from the portable transmitter. Applying thir guidance to the transmitters used for this evaluation, the minimum distance that these transmitters can be operated from SRV Electric Lift circuit components (PAM Panels) is, from table 1, effectively 1.0 meter for the cell phone,4 meters for the 850Mhz radio transmitter and also for the 5 watt walkie-talkie. Based on plant experience with the walkie-talkies operated previously at frequencies up to 450 Milz, this distance is assumed to be a conservative distance. CllAR had to acknowledge that, for the same reason that portable radio transceiver manufacturers advertise improved communications at higher frequency, inadvertent antennas in critical equipment will also see increased coupling *. The principal reason for this improvement in communications can be attributed to penetration of areas that would appear to be shielded at lower frequencies (or a relative increase in the E-field levels) so that the receiving radio has improved perfoimance , compared to the lower frequency. This increase in E-field strength (considered because most walkie-talkies use E-field whip antenna with consideration that the signal is actually a wave except in the near field) can be attributed to actual direct radiation from the transmitting radio or conduction and re radiation by conductors such as cable shields, ground wires, pipes, etceteras in the area.
'The initial draft version of EPRI TR-102323 called for a reductior of a factor of two (6 dB) of the plant emission level sersus the test immunity level. Recent studies has : incorporated an additional margin for measuiement totenmce and the recommended reduction of ra uor of 2.5 (8 dB) reduction in plant emission level versus test immunity level. Thus. if the immunity test levelis 10 V/m, the maximum recommended plant emission les el at the location of the equipment under ter. is 4 V/m.
'IEEE C95,1-1991 uses a derating formula for allowable power transmission as frequency (Milz) divided by 450(Mlle) While this Standard duh with human exposure, the derating has some relevance in recognition of the increased coupling factor as frequency increases.

REPORT CSR090. PAGE 9 While radiation losses are clearly explained in the attachment to this report and show an E-lield strength falling off proportional to distance, the conduction losses will be proportional to both distance and frequency because of the losses attributed to the conductors. The conduction path (twisted shielded pair cable) for the wide range transmitter PT-263-114, resulted in attenuation of a calculated value at the transmitter of = 127 dBpA (using a characteristic impedance of 50 ohms) to a measured value of only 76 dBpA at the input to the Foxboro rack, for a reduction of 51 dB. Although the common mode reduction at the rack is significant, the initiation of alarms and circuit response indicate that EMI was able to couple normal mode at the transmitter thereby causing the system upset. As another example. viewing the attenuation of a type 9059 RG-59 coaxial cable produced by Alpha wire company, the attenuation per 100 feet of cable at 400 Milz is 6.7 dB and at 1000 Mllz is 11.5 dB. 6.7 dB represents a factor of 2.16 reduction while 11.5 dB represents a factor of 3.76 reduction, precise values can not be determined for in plant cable losses, but it is safe to conclude that there will be added conduction losses at high frequencies and using a factor of 0.7/100 feet as the relatise gain for the conductors at 800 Milz versus 450 Mllz is a reasonable estimate. 2.1.1 Summary of EMI concerns l Identificction of Major EMI Safety Concerns The indor safety concern for the SRV ELECTRIC LIFT circuit is a common mode failure that would affect all the redtmdant systems at one time. Actually there are only two EMI scenarios that could affect more than one SRV ELECTRIC LIFT circuit at a time. They are:
- 1. A high level radiated signal that could reach both Narrow and Wide range transmitters simultaneously.
- 2. A power surge affecting more than one vital bus or a large number of signal lines at one time.
3.0 DISCUSSION OF RADIATED ENVIRONMENT A radiated EMI would be a threat as a localized enviromnent in the control room, over the entire site, or in areas where there is a possibility of radiating SRV Electric Lin circuit interconnecting cables with a high energy local transmitting source. It is considered a sinusoidal (continuous ware) source (which may be modulated) as opposed to the pulsed or transient EMI. Known sources that could cause radiated interference in this band are radio, television. communications or security transmitters. Iland held transceivers (walkie-talkies) are known to generate EMI having a tield strength approaching 10 V/m at I meter distance. Ol9%Cil tR SERVICES. INC. ALL RIGillS RESI.InTD.

3.1 DISCUSSION OF POWER SURGES AND LINE SPIKING 3.1.1 Power Line Surges Power line surges are defined in IEEE Std C62.41-1991 and are caused principally by lightning, fuse operation on long lines, and capacitor switching surges. This standard points out in paragraph 7.4...
"Furthermore, the SWC (Surge Withstand Capability test related to lightning, etc.) test is primarily intended for the high voltage substation environment, while the EFT (Fast Transient test) is intended for general industria! equipment. Therefore, this recommended practice encourages the use of the EFT test over the SWC test."
The vital ac bus supplying power to the SRV ELECTRIC LIFT system is not exposed to lightning and its relatively short distribution lines do not represent high line capacitance capable of providing the energy for the surge EMI. Nor is it possible to create a surge through normal plant operation. The impulses during switching off the vital feed are not L operational surges and are normally expected transients caused by opening the circuit to an l inductive load. The concern for the power line surge tnmsient is relatively low. l l 3.1.2 Power Line Spikes (Fast Transients)
- Fant inmsients are caused by- circuit interruptions of inductive loads or switching on capacitive loads and could be created on a vital ac bus by switching a load on and/or off.
While the redundant digital systems are fed by separate vital buses and loss of a single bus-or digital channel would not be a safety concern, there might be concern that, due to the frequent occurrence of fast transients, EMI could occur independently on separate vital buses at the same time, creating a common mode failure. Section 3.1, Power Line Surges dealt with this issue also. 3.1.3 Fast Transients on Signal Cables The signal input cables are connected to low level anidog input / output devices that will not in themselves create any of the high amplitude thst transients associated with power lines. The high level power line transients will still couple to these cables, but they will be significantly reduced through the coupling circuitry and by the long cable length from the remote transducers to the SPEC 200 micro control module. The highest level of EMI would be expected to be generated by the switching actions of circuits such as 120V ac relays close to the digital system. 4.0 MEASUREMENT OF EMI LEVELS IN Tile PLANT Prior to performing testing, CHAR Services met with the site engineering representative at the plant to identify the most likely sources of EMI that would couple to the digital system, O!9%C11AR si:RvlCES. INC. Al.l. HIGH rS Rl;SE;Hvi:D.

It is the intent of this report to bound the expected levels at point of installation with the maximum emission levels obtained and documented during testing for compilation of EPRI TR-102323. 4.1 Conducted Emissions, Transients Conducted transient emission tests have been perfbnned in this case as an investigative test to examine the plant emissions at the point ofinstallation. The test utilizes current probes, placed around selected cables, and a digital oscilloscope to record the current magnitude using various sweep-rates. As an investigative tool, there are three benefits:
- 1. The tests can identify relative levels and frequencies of emissions and this data can help track down undesired emissions such as switch arcing, inductive cycling or instrumentation operating outside its design characteristics.
- 2. Data on similar systems can be compared between installations.
- 3. Data can be compared to related susceptibility tests by taking into account ditTerences between the source and load impedance's for each test condition In examining the test data, it must be remembered that the mapping measurements are being made as current at the input to the digital equipment on lines that may have either grounded shields or high frequency filters. Both of these conditions will represent input impedance's that will be relatively low impedance between 1 Mllz and 100 hiliz, the spectrum of the transient pulse. The load impedance may be considerably less than the 50 ohms referenced in the Standards for the Susceptibility test set up. Therefore, the measured current may be relatively high, not because of actual EMI levels, but simply because the digital equipment EMI protection design is peribnning as designed, The transient may or may not be limited by the characteristic impedance of the input lines, depending on the distance to the source of the transient.
4.2 Examination of RF coupling levels in the PAM Panels EMI was generated by actuation of radio transmitters at various locations in and outside the PAM room. Actual measurements were made for common mode coupling on the cables providing input from the RX pressure transmitters and between the cables interfacing with the control room. The table on the following page is a summary of these measurements: eimcu ut stuvicts. nc. Au nicirrs su:su<vEn.

! 4.2.1 Comparison to other facilities The maximum transient level measured was < 90 dBpa common mode and is consistent with levels recorded in similar testing at other plants. There was no L direct correlation to plant equipment operation causing any of the recorded transients, however transients induced by welding equipment was documented.
4.2.2 Limitations on comparing this data to susceptibility test levels CHAR Services believes that this data can be conservatively compared to the Susceptibility Test Levels.1-lowever, CllAR Services cautions that high currents may mean effective filtering rather than high levels of EMI. In the event that there is reason to suspect a detrimentally high level (above the Susceptibility test limits), the termination on the cable or cables being measured should be replaced with a 50 ohm terminatioa to obtain an exact correlation with the Susceptibility Test Conditions. 01996CllAR SERVICES.

REI ORT CSR090. PAGE 13. 5,0 CONCLUSIONS / RECOMMENDATIONS CllAR recommends that exclusion areas be identified around the installation areas for the transmitter racks and the PAM panels. A minimum distance of four meters should be maintained for both, with the equipment doors for the PAM panels securely closed. Although still considered conservative, the current signage with restrictions of no portable transmitters be allowed to operate within 30 feet could be modified to isolate just the PAM room and the transmitter rack room. Many plants identify the control room and cable spreading room as radio transmitter free zones. An alternative to this approach is to identify transmitting zones where one can operate portable transmitters in an otherwise prohibited area. Additionally it would be prudent to inspect the raceway, shielding and ground configuration of the wide range transmitter circuit PT-263-ll4 from the transmitter to the PAM room. Specifkally looking at the shield termination at the transmitter housing and then watinuity of the shic!d back to the PAM room. The transmitter response to direct contact of the walkie-talkie output resulted in normal mode coupling which is indicative of loss of shielding or change in signal return configuration.

2 Radiation froin Imperfect Antennas . Assumption:- Antennas do not radiate equally in all directions, instead of a spherical pattern, it looks more like a rolling donut in a direction normal to the vertical dipole or whip antenna. Ot9%CIIAlt SERVICES,INC A1.L RIGilTS RESERVED.

Unequal Power Distribution over Spherical Wavefront Power Gain: the result is an appaunt gain in the transmitted power when compared to the theoretical spherical wave - at some point normal to the antenna. This is due to the focusing of the energy over just a portion of the theoretical sphere.
