ASC.#1.was issued to add interposing relays in the TGIS panel to enable proper interface with output contacts of the new Ammonia and Butane analyzers installed in this DCP. In the proposed design of the DCP, the new Siemens Butane and Ammonia analyzers high concentration and the channel failure contacts were used in circuits which operate 120 VAC relays. A subsequent review of the Siemens i vendor manuals for the Butane and Ammonia analyzer indicated that the output l contacts are only rated for 24 VAC or VDC. In ASC #1,24 VAC interposing relays were installed to ensure that the analyzer contacts are operated within the vendors j rated voltage. A 120/24 VAC transformer is used to operate 24 VAC relays. Output '
contacts from the 24 VAC relays operate existing 120 VAC time delay relays. In addition, fuses are installed to provide adequate protection for the transformer and relays.
ASC #{hlso;moslifiedlthe operation of the output contacts of the Butane analyzer.
This DCP specified Siemens Ammonia and Butane analyzers with output contacts that open on a high gas concentration to initiate TGIS. During the inspection and testing of the analyzers it was determined that the Ammonia analyzer contact closed on high gas concentration. SCE requested the vendor to modify the Ammonia analyzer contact operation but the vendor declined to do so. When spare Butane and Ammonia analyzers were ordered, Siemens notified SCE that current design Butane analyzer contacts operate in the same manner as the Ammonia analyzer (closed on high gas concentration). Siemens stated that the Ammonia and Butane analyzers contact operation was their standard design and requests to modify the relay operation were declined. It was decided to utilize the vendor's standard design. Therefore a revised EPROM (Erasable Programmable Read Only Memory) furnished by the vendor will be installed to make the Butane analyzer

l Affected Section Change No 2 contacts close on high gas concentration thereby conform to the vendors standard design. This change also makes the Butane and Ammonia analyzer output contacts identical in operation. Appropriate modifications will be made in the control circuit to accommodate the change. The high concentration output contact of the Butane analyzer will energize a 24 VAC relay, the contact from this relay will l de-energize the existing TDD relay. The Ammonia analyzer high concentration !
output contact will also energize a 24 VAC relay and a contact from this relay will also de-energize the existing TDD relay.

This Design Change Package addresses the replacement of obsolete analyzers in I the Toxic Gas isolation System (TGIS)for the reasons discussed as follows:
l Toxic chemical release is an accident condition for which theLNorpNSSS Engineered Safety Features Actuation System (ESFAS) provides protective action i through TGIS. TGIS contains safety-related instrumentation and controls that automatically aminate the supply of outside air to the main control room in the ;
event of a toxic gas release at the SONGS site or on interstate 5 or adjacent rail line. TGIS isolates the ventilation to the control room and initiates operation of the l emergency HVAC system in the control room to minimize operator exposure if a j toxic hazard is detected. TGIS also activates an alarm in the control room to alert l operations personnel. Normal ventilation can only be restored manually by the ;
control room operator after TGIS has been reset.
The TGIS gas analyzers are mounted in panel 2/3L378 located at the 9 ft. level of the Control Building. Two independent, redundant sets of sensors are provided to detect the presence of toxic gases for the system to perform the required isolation function. The redundant sensors provide two independent and redundant trains of TGIS. The toxic gases monitored are Butane / Propane (hydrocarbons), Ammonia, and Chlorine.
The TGIS panel was designed and fabricated with instruments purchased in the early 80's. Over the years, progress has been made in the field of analytical l instrumentation, making this older generation of instruments obsolete. The original vendor of the Ammonia and Butane analyzers, Beckman Instruments, sold their analyzer division to Rosemount Analytical Inc. Rosemount discontinued the Model 400 Hydrocarbon Analyzer and 865 Infrared Ammonia Analyzer and spare parts for l these analyzers are no longer available. ;
The Chlorine analyzers, made by Wallace & Tiernan, are still in production and l spare parts are available. The maintenance records for these analyzers indicate
DCP 2/3-6933.00SJ REV. O SH..$L Affected Section Change No 2 that replacement at this time is not necessary.
The existing Ammonia analyzers have experienced problems in drifting low (less than zero parts per million (ppm)), which gives an unacceptable indeterminate indication. Although calibration has usually shown the drift to be less than the 5%
drift accounted for in the TGIS setpoint calculation, the maintenance costs associated with frequently restoring the above zero indication are significant.
Additionally, the analyzer drift has been deteriorating and has exceeded 5%
several times in the last 24 months. The increased drift is a function of component aging, and is expected to get worse as the analyzers get older.
These Ammonia analyzers have had a poor maintenance record and have been the cause of several spurious TGIS trips. Parts are becoming more difficult to obtain and, in some cases, are only available as substitutes requiring system modification. The two installed analyzers have different termination arrangements and are not interchangeable without design changes. This requires additional maintenance effort to keep two rebuilt analyzers available for replacement, which will ultimately result in reduced reliability.
Although the Hydrocarbon analyzers are not experiencing a significant amount of maintenance problems, compatible spare parts are no longer available.
The TGIS analyzers are presently furnished with 120 Vac power from common MCC's 80 and BS. Due to the addition of an air combustor in the original design, the voltage drops experienced by the analyzers could approach the analyzer voltage specifications under worst case conditions of maximum load. It is preferable to furnish instrumentation frorn a regulated and conditioned power source.
The TGIS panel is located outside of the 9' elevation elevator in the Control Building which is open to considerable traffic and noise. All of the existing analyzers are potentially sensitive to temperature and electronic noise which affects their reliability. The panel is currently lined with lead blanketing and the front panel doors are lined with a Faraday shield for RFI protection. In addition, the area is posted with "No Radio Use" signs. The current level of protection will be maintained.
Local annunciation is provided at the TGIS panel 2/3L378. "TGIS Actuation" and "TGIS Trouble" alarms are annunciated on 2/3UA0060B and 2/3UA0060T in the main control room, and "TGIS Manual Actuation" and "TGlS in Reset / Bypass" indications are available through the Plant Monitoring System (PMS). There are no recorders provided in the present design of the sys, tem, thus it is difficult to determine after a TGIS actuation whether or not the actuation was caused by a
DCP 2/3-6933.00SJ REV. O SH.1 Affected Section Change No 2 voltage spike or by a true gas release. Following a TGIS actuation, a plant equipment operator is sent to the TGIS panel to determine the cause for actuation.
The TGIS panel is inherently congested, making access for routine maintenance and surveillance testing within the cabinet extremely difficult.
The Reset / Bypass switch (2/3HS-9784B1,82)is a momentary contact push-button switch currently located on the front of the panel. The bypass function is obtained during calibration checks by jumpering the Reset / Bypass contacts, othenvise the technician has to maintain the switch in a depressed position during testing.
Installation of the jumpers is time consuming due to the location of the terminal strip in the congested TGIS panel. In addition, the use of jumpers is discouraged for safety concerns; if the jumper is not removed it leaves TGIS inoperable.
The compressed gas bottles that support the TGIS system are mounted in the Control Building 9 ft. level passageway, making it difficult to bring in new bottles.

1.B FUNCTIONAL OBJECTIVE FOR CHANGE Functional objective of A.SC #iwas to provide proper operating voltage for the new ,
l Butane and Ammonia analyzer output contacts and also make the Butane analyzer design consistent with the manufacturer's standard. Four additional class 1E interposing relays, one 120/24 VAC transformer and two fuses will be installed for each train of TGIS. The relays, fuses and the transformer will be installed on a plate mounted in the TGIS panel. Installation of these devices requires the relocation of the Reset / Bypass l switch mounting plate installed by the DCP. The Reset / Bypass switch will be mounted on the same mounting plate used for the interposing relays, fuses and the 120/24 VAC transformer. An analysis to verify that the changes did not affect the seismic qualification of the panel has been performed. E actricalloading calculations have been revised. The additional relays will not affect the functional operability of the TGIS.
, Installation of the vendor's standard Erasable Programmable Read Only Memory (EPROM) on the Butane analyzer will make its output contact operation identical to the Ammonia analyzer.
The functional objective of th;s design change is to provide replacement analyzers for obsolete equipment in the TGIS system. An additional objective is to reduce spurious trips experienced by this system and provide a means of operator evaluation of a TGIS actuation. This design change will reduce costs associated with reporting of spurious actuations, as well as the cost of maintenance and operator actions. Benefits will elso be achieved by means of confirmation of an actual toxic hazard.
This design will implement the following change's:
- 1. Change the power supply for the Ammonia, Butane and Chlorine Analyzers from MCC's BQ fer Train A, and BS for Train B, to the 120 VAC Vital buses YO1 and YO2 respectively. The TGIS sample pump and combustor will remain powered by the MCCs BQ and BS. The system will no longer actuate on power transfer from Unit 2 to Unit 3 since these analyzers are powered by the vital busses, which are uninterruptable power sources. A" Loss of Sample" and "TGIS Trouble" alarms will be not be initiated as long as the power transfer frorn Unii 2 to Unit 3 or vice versa, is accomplished within 5 seconds.

- 7. Remove the grating directly outside the double doors (AC101) leading to tha 7 ft.
Turbine Building to provide a more direct access to the compressed gas bottles for TGIS maintenance. The grating is not a security barrier or otherwise credited in the security plan and is not reflected in any plant drawings. To minimize spurious TGIS actuations caused by unrestricted personnel traffic in the area, provide a key lock, controlled by the shift supervisor's office, on the AC101 doors. Opening of these doors for other than normal ingress and egress must be performed in accordance with the barrier control program.
1.C SITE PROGRAMS
- 1. Operations impact Replacement of the Ammonia and Butane analyzers will not modify plant system functions or design basis. The design changes will improve operator performance ,
by providing pertinent information in the event of a TGIS actuation through the strip chart recorders. {
l Affected procedures include, but may not be limited to- I SO23-II-8.22, TGIS Time Response Test and Channel Functional SO23-II-1.15, TGIS Train A Channel Functional and Calibration SO23-ll-1.15.1, TGIS Train B Channel Functional and Calibration SO23-15-60.B, Alarm Pesponse Note: Applicable procedures must be revised prior to implementation to be used for post construction testing.
The Alarm Response Procedures, Operating Instructions and Operation Procedures need to be revised to update the modifications made. The LCO will be affected due to the 7 day action statement when only one channel of TGIS is operable. If both trains are out of. service, a one hour action statement is in effect to place the control room in the isolation mode of operation.
Procedures goverriing key control will need to be updated for the key lock added to door AC101.

_Affected Section Change No 2
- 2. hiaintenance impact Addition of a 120/24 VAC transformer and 24 VAC relays impacts the maintenance procedures.
The design changes impact mainte' nance procedures for the replacement analyzers, bypass switches and recorders. Since the new analyzers and recorders are powered from the vital bus, the procedures need to be modified for removing these instruments from service. Maintenance procedures must insure that the TGIS bypass condition is removed after any maintenance or testing activities. This will include key removal and verification that light 2/3ZL9784B1 (2/3ZL978482 for Train B) is lit.
Surveillance test procedures will need to be revised to reflect the new analyzers, the new recorders, and the transfer of power to the Vital Bus.
- 3. Site Fire Protection Group Impact The Technical Specification Surveillance Procedures will need to be updated to identify the added lock on fire door AC101.

, 12. Radwaste Treatment Systems impact There are no changes to radwaste treatment systems subject to semi-annual reporting per Technical Specifications.
- 13. Electrical System Loadina impacts The additional transformer and interposing relays increase the load in each vital bus 2&3 YO1 and 2&3 YO2 by about 325 VA which is considered insignificant. ;
ICCN No C-41 and C-42 to electrical calculation E4C-017 Rev 13 have determined l that the increase in load to the vital busses and the Class 1E 125 VDC Batteries is within the margins provided in the Battery Loading. Consequently, the battery loading profile and the loading on the emergency diesel generators are not i affected.

l e

bus power to these analyzers. However, the catalytic combustors, which provide hydrocarbon free air to the Butane analyzers for zeicipoint calitiratiori will continue to receive power from the distribution panels 0033 and 0035. Therefore, there will be a net decrease of power supplied by each of these panels of 900 watts (from 1500 watts to 600 watts). An ICCN,to Calculation E4C-086 has been generated to document this load reduction. Since this is a load reduction, the Diesel Generator loading as defined in Calc. E4C-088, Emergency Diesel Generator Loading, is still bounding and does not require a change to the calculation. In addition, the Voltage Regulation Calc., the System Dynamic Voltages during DBA Calc. and the Short Circuit Studies Calc. have been evaluated and are not impacted.
This DCP adds recorders and replaces the Butane and Ammonia analyzers with newer models which require less power. The power to these instruments will be supplied by the vital busses 2YO1 or 3YO1 (Train A) and 2YO2 or 3Y02 (Train B).
There will be an increase in loads to these busses and consequently to the A and B train DC systems.
The total load of these instruments is 490 VA which includes 200 VA to the internal heater of the Butane analyzers. This heater is used only when the Butane analyzer is initially started and automatically shuts off after the analyzer is ready. !
Since this load exists for a very short period of time during instrument start up, it is not considered to be a continuous load and is not required to be included in i Calculation E4C-017. The net increase in load on Train A and B vital busses is 325 VA. There is a cormsponding increase of 3.45 Amps to both Train A and B battery loads. The load profile computed in E4C-017 Rev 13 includes a 10 Amp margin for contingencies. The additional load imposed on the batteries by this '
DCP will reduce the contingency margin available to 6.55 Amps. The battery load profile will not be affected.
An Engineering evaluation has determined that the voltage drops and fuse sizes of 2(3)YO1-25 and 2(3)YO2-21 are adequate.
- 14. Main Control Room Operating Area This modification is designed in conformance with the Control Room Design Standard for Human Factors (JS-123-101 Rev.1). The design changes are confined to the area surrounding the TGIS Panel.
- 15. Regulatory Guide 1.97 Criteria This modification does not affect the Reg. Guide 1.97 criteria.

Dear Sandy,
j dear Steve, l You gave us a hard time becauce moct of our intems! documentation la in German.
l F.nclosed is what we managed to compile in English.
Concering EMI / RFl. I have enclosed the original EC Centficate of Conformity for the l
- FIDAMAT (in German only). (As you know, CE is a must for deliveries in 1996.)
l i e
! ! The ULTRAMAT 5 has net been certified yet, but I have enclosed cil available test i infnrmation to date, which is valid for your unit.
The tests were made in our test center in Kartr,ruha. We sincerely hope that we don't need ~
to translate all of this.
With best regarde, h N D 9

inkt, die.ser Sette estum 201.95 Sousnum 2 1.me!. thia Pace Date Number cf Pa;os Siemors ULTRAMAT and FIC AM AT J. Your fax to Glenn Schuelke dt.17 Nov. 95 Deat Jim, I m happy to answer all your questions poshlvely, as follows:
Of course we are cer:lfled to the ISO 9000 system, speelfically to ISO 9001 ref.1.
(design, development, production, installation, and servicing). A copy of the cer:ificate is attached.
You can imagine that a large company such as Siemens has quality standards and procedures for everything, which adds up to tons of paper!
ref. 2. For exampie, the FIDAMAT has an integral" watch dog" function; error 1 Indicates "processer slave defective *
- error 3 indicates " heating eff", e.g. due to overheatlng and shut off erect 9 indicates E PROM check f aulty (check sum check)
Additionally, tnere is a continuous parameter plausibility check:
error 8 with various sub No's indicate which parameist See also the manuals for further reference, ref.3. At start-up check sum is checked. Replacement of E PROMS with same software version must have the same check sum. Updated software will result in a new check sum.
ref.4 We have r#cre than 600 FIDAMAT and several thousand ULTRAMAT in field. Malfunctions of sub ccmponents are really rare,if so, an alarm was always set off. Up to now we have not experienced any " hidden'f ault".

This limit can be entered with fet 79.The value is a percentage value of the octual measuring range.On the ULTRAMAT 5 - 2 R each channel could have a different limit.
If the cal deviation is larger than the specified limit the following alarms show up: 1 zero cal, channel 1 u31
