DESIGN CHANGES The following design changes were approved for implementation by the On-Site Review Committee in 1979. Except as noted, the design changes were fully implemented as of the end of the calendar year 1979.
This list fulfills the reporting requirements of 10 CFR 50.59(b) and Environmental Technical Specification 5.6.1.b. With respect to the latter requirement, none of the 1979 changes resulted in a condition which significantly altered the impact of the Station on the environment as described in the NRC Final Environmental Statement and did not involve a change in the Environmental Technical Specifications incorporated in the San Onofre Unit 1 Provisional Operating License DPR-13.
- 1. DESIGN CHANGE 78-12 (Revision 1):
YARD DRAIN AND REHEATER SUMP PUMP CONTROL MODIFICAFION (In Progress)
Revision 1 to Design Change 78-12 identified the oil storage tanks in the vicinity of the yard drain system sump and reheater pit sump. This Design Change was implemented in order to control and contain spills by the addition of oil detection devices to the yard drain system sump and reheater pit sump. This action was the result of 40 CFR 110 which requires containment of the oil spilled from the largest single oil container without any operator action being taken to control the extent of the oil spill.
- 2. DESIGN CHANGE 78-20 (Addendum II): STARTUP WASTE WATER DISCHARGE SYSTEM (Temporary) INTO UNIT 1 CIRCULATING WATER OUTFALL SYSTEM Addendum II was initiated to more extensively review the environmental impact of Design Change 78-20 which consisted of coring a penetration in the Unit 1 circulating water outfall tsunami structure along with piping installation to allow discharging of Units 2 & 3 Startup waste water. The addendum discussed the addition of the Hydrostatic Test and Flush Waste Water to the combined discharge.
- 3. DESIGN CHANGE 78-35: ADDITION OF COOLING FANS TO STATION SERVICE TRANSFORMERS This Design Change proposed the addition of fans (two fans in each of the three station service transformers), for forced air-cooling, to increase the KVA rated capacity by 15% as required by the new SPA/SEP modification load increase to the transformers.
- 4. DESIGN CHANGE 79-01:
INTERCHANGEABILITY OF STEAM GENERATOR PRIMARY MANWAY CAP SCREWS AND THREADED STUDS AND NUTS (In Progress)
This Design Change justified the use of threaded studs and nuts to seal the steam generator primary manways instead of cap screws which were originally furnished as part of the steam generators. The cap screws and threaded studs and nuts are interchangeable in any number desired.
Using studs and nuts allows bottoming of the stud and thus provides more usable thread engagement as compared to cap screws ensuring that additional threads in the threaded hole are utilized to evenly distribute axial loading.
- 5. DESIGN CHANGE 79-02:
TEMPORARY INSTALLATION OF A SPENT FUEL SAFEGUARDS SYSTEM The proposed temporary installation of spent fuel safeguards equipment at Unit 1 by Sandia Laboratories was described. The equipment consists of nine sensor modules, two closed circuit television cameras, a data collection module, and associated cabling. Two telephone lines are used to transmit data to the central monitoring and display module located in Albuquerque. This detection system is conceptual in nature and is part of a larger research and development program to develop a reliable system to prevent the proliferation of nuclear explosive devices.
It is anticipated that the final detection system developed will be used by the U.S. Government in agreement with foreign countries through the International Atomic Energy Agency.
- 6. DESIGN CHANGE 79-02 (Revision 1):
TEMPORARY INSTALLATION OF A SPENT FUEL SAFEGUARDS SYSTEM This revision describes a few minor changes to spent fuel safeguards system equipment installation. It also provides for capability for Southern California Edison to review and approve all video pictures taken and stored in the data collection module through the use of a Sandia-supplied on-site video display terminal.
- 7. DESIGN CHANGE 79-03:
SITE DEVELOPMENT PLANT MODIFICATIONS (In Progress)
Parking, roadways and landscaping in the plant area outside the protected area barrier on the north and east side of Unit 1 were provided by these site development modifications. Most of these modifications are external to the plant protected area and cover roadway accessibility to the plant and landscaping only.
- 8. DESIGN CHANGE 79-03 (Revision 1):
SITE DEVELOPMENT PLANT MODIFICATIONS (In Progress)
The original design change evaluation and basis for safety finding was revised to include site security as a possible area of impact by these modifications. The site security concern was related to the requirement for a twenty foot exclusion area next to the security fence. This was maintained in the new site development configuration. No other revisions were included in the design change.
- 9. DESIGN CHANGE 79-04:
RELOCATION OF GUARDHOUSE (In Progress)
The guardhouse was relocated from the north end of Unit 1 to the top of the bluff in the area of the current entrance of the plant in order to control entrance to San Onofre Nuclear Generating Station.
- 10. DESIGN CHANGE 79-06:
INSTALLATION OF NEW AND SPARE AUXILIARY C TRANSFORMERS (In Progress)
This Design Change discussed replacement of the 138 kv/4 kv C transformer with a new 230 kv/4 kv unit and the installation of a new spare auxiliary C transformer in order to accommodate a new 230 kv transmission line voltage superseding the 138 kv supply line. This change is non-safety related since it affects an auxiliary power supply which is not essential for safe shutdown of the plant.
- 11.
DESIGN CHANGE 79-07:
BORIC ACID HEAT TRACING SYSTEM MODIFICATIONS (In Progress)
This Design Change replaces the original heat trace cables with a flexible heating tape in which current passes through a resistive core between parallel conductors, forming a continuous heating circuit.
Failures in the old heat tracing, caused by degradation of the wire insulation resulting in short circuiting, prompted the replacement which will increase the reliability and maintainability of the trace heating.
Replacement circuits were tested to ensure compliance with technical specifications before being returned to service.
- 12. DESIGN CHANGE 79-08: DIESEL GENERATOR MODIFICATION This design change covered the modifications to the emergency diesel generators as follows:
- 1) Diesel engine pushrod replacement
- 2) Improvement of the air supply filter for the starting air distributor
- 3) Addition of a positive mechanical stop for the cylinder fuel injection pumps
- 12. DESIGN CHANGE 79-08:
DIESEL GENERATOR MODIFICATION (Continue)
- 4) Installation of a new design terminal lever pin for the governor/actuator.
- 5) Replacement of fuel oil transfer pump packing seals with durametallic mechanical seals.
These improvements were recommended by the equipment manufacturers and the parts were supplied by the vendors.
- 13.
DESIGN CHANGE 79-09:
NUISANCE ALARMS MODIFICATION (In Progress)
This design change consisted of modifications to the following alarm systems:
- 1) "Battery Charger Failure A/B" and "Battery Charger Failure C/D" now requires failure of both chargers (A&B or C&D).
- 2) "Hydrazine Flow Low" now requires at least one hydrazine addition pump to be started before the low flow alarms are enabled.
- 3) "Containment Spray Flow Low" now requires a CSAS alarm to occur on either train (A or B) before the alarm is enabled.
These changes improve the presentation of meaningful information to the operators, and thus enhance operational safety.
- 14. DESIGN CHANGE 79-10:
FIRE PROTECTION MODIFICATIONS (In Progress)

DESIGN CHANGE 79-19:
UNDERGROUNDING OF THE 12 KV LINE This modification replaced the 12KV line to the 12KV/480V transformer feeding switchgear 2 bus with an underground cable to improve personnel safety during turbine gantry crane operation which was an overhead electrical hazard. The underground line runs 160 feet south of the station transfer, then west for 180 feet before crossing the Units 2 & 3 area boundary.
- 24. DESIGN CHANGE 79-22: T SAT RECORDER A three pen recorder was installed to record and indicate:
- 1) Reactor Coolant T-Hot
- 2) Saturation temperature of the reactor coolant based on pressurizer pressure
- 3) The difference between T-Hot and T-Sat. An alarm was provided to annunciate when T-Sat-T-Hot is less than 400F.
- 25. DESIGN CHANGE 79-23: REACTOR COOLANT PUMP TRIP ON SAFETY INJECTION This design change consisted of installing a circuit to trip all reactor coolant pumps on safety injection.
The trip circuit was designed to energize when the HFA relay contacts close due to closure of a contact on either sequencer.
- 26. DESIGN CHANGE 79-24: ADDITION OF A FILTER TO THE RADWASTE DISCHARGE LINE (In Progress)
This Design Change required the installation of a 0.2 micron filter downstream of the existing 20 micron filter in an attempt to minimize the total number of curies per year released to the environment. This filter addition reduces the discharge contamination by about 20%.
- 27. DESIGN CHANGE 79-24 (Revision 1): ADDITION OF A FILTER TO THE RADWASTE DISCHARGE LINE (In Progress)
This revision changed the equipment specification on the filter element type and filter housing used in the original design change.
- 28. DESIGN CHANGE,79-25: REFUELING WATER PUMP SUCTION LINE (No. 729-8"-HP) REINFORCING COLLARS Repair modifications to the refueling water pump suction line #729 were incorporated to assure the structural integrity of the line No. 729-8"-HP in view of cracking discovered during inspections required under IE Bulletin 79-17.
Six cracks, circumferentially oriented and approximately 1/4 inch to 1 inch in length, were found; a) two in the heat affected zone of weld #729-16 which joins the refueling water suction piping to the suction side isolation valve of refueling water pump G-27(N) and b) four in the heat affected zone of weld #729-6 which joins a 1 foot vertical run of pipe to an elbow in the common suction line to both refueling water pumps. The probable cause of the cracks was considered to be chloride stress corrosion.
The repairs to the two affected areas (i.e. welds #729-6 and 729-16) entailed fabricating four half circular reinforcing collars (two halves for each affected weld) from carbon steel formed to the contours of the pipes, centering the collars over the affected welds and bolting them in place. Stainless steel shims were inserted between the pipes and collars for pipe corrosion protection.
- 29. DESIGN CHANGE 79-26: T-CONNECTION ON AIR PALLET AIR SUPPLY LINE A 3" T-connection with related isolation valve and piping was installed on the air pallet air supply line, thereby providing an alternate connection for the diesel air compressor used in air pallet operations and eliminating the long air hose that extended from the diesel air compressor to the turbine deck.
- 30. DESIGN CHANGE 79-27: RADWASTE DISPOSAL SYSTEM LINE SUPPORT MODIFICATION This Design Change is for installation of pipe support IT-7076-A-004 on the Radwaste Disposal System Line as a result of a field inspection which discovered the said pipe support to be missing. This pipe support is required to insure pipe integrity in the event of an earthquake.
- 31.
DESIGN CHANGE 79-29:
IN-PLANT PAGING SYSTEM (In Progress)
The work accomplished by this Design Change consisted of upgrading the In-Plant Paging System in order to correct audibility problems encountered on evacuation of personnel from high-noise areas as follows:
- 1. Immediate evacuation signal expansion with an additional large warning siren plus interior and exterior local alarm horns.
- 2. Area Radiation Monitoring System (ARMS) Alarms addition.
- 3. Plant Public Address System upgrading by additional speakers and visual signals in high noise areas.
- 33. DESIGN CHANGE 79-31:
NITROGEN SUPPLY TO THE PORV BLOCK VALVES (TMI)
(Installed February 1980)
This plant modification provided a redundant source of motive power to the PORV block valves utilizing the existing station nitrogen system as the back up supply. In addition, the nitrogen system containment isolation valves were modified to provide a continual nitrogen supply during containment isolation.
- 34. DESIGN CHANGE 79-32:
DIRECT INDICATION OF VALVE POSITION FOR SAFETY PORV & BLOCK VALVES (Installed February 1980)
This plant modification consisted of adding stem mounted limit switches to the two pressurizer safety valves and replacing the limit switches on the two pressurizer PORV's and their associated block valves.
Two alarms, one for the safety valves and one for the PORV's, were provided in the control room to annunciate if any of the safety valves or PORV's open.
- 35. DESIGN CHANGE 79-33: DIVERSE CONTAINMENT ISOLATION (Installed February 1980)
This modification consisted of providing a redundant and diverse Containment Isolation Actuation Signal (CIAS). The previous CIAS was derived from a measurement of containment pressure and isolation occurred at a pressure of >2 psig. This modification resulted in CIAS also occurring when a Safety Injection Isolation Signal (SIAS) is initiated. Automatic re-opening of the Containment Isolation valves is prevented by sealing in the CIAS so that the following conditions must be present to allow opening the isolation valves after initiation of CIAS:
- 1) Containment pressure below 2 psig
- 2) Removal of SIAS by sequencer resetting
- 3) Operation of containment isolation valve switches
- 4) The two CIAS reset pushbuttons operated.
- 36. DESIGN CHANGE 79-34: AUXILIARY FEEDWATER SYSTEM MODIFICATIONS (TMI)
(Installed February 1980)
This modification consisted in automating the Auxiliary Feedwater (AFW) motor driven pump by:
- 1) Installing and automating a Motor Operated Valve (MOV) in the pump discharge header to the west main feedwater line.
- 2) Addition of flow measurement from the main feedwater lines for the three main feedwater control valves.
- 3) Addition of locally indicated flow measurement in the three manually controlled AFW lines.
- 4) Redundant condensate storage tank level indication with associated alarm in the control room.
Both the motor driven AFW pump and the new MOV are automatically initiated by a low steam generator level signal from 2 out of 3 level transmitters associated with the steam generators. Remote operation from the control room is provided for the motor driven (AFW) pump and the new MOV.
