SAN ONOFRE NUCLEAR GENERATING STATION DESIGN CHANGES APPROVED DURING THE YEAR 1980 The following design changes were approved for implementation by the On-Site Review Committee in 1980.

Except as noted, the design changes were fully implemented as of the end of the calendar year 1980. This list ful fills the.reporting requirements of Section 5.6.1b of the Environmental Technical Sp~cifications. With respect to this requirement, none.of the 1980 changes resulted in a condition which significantly altered the impact of the Station on the environment as described in the NRC Final Environmental State ment 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 80-02: MODIFICATION TO VENT VALVE ACTUATORS TO LIMIT OPENING TO 500 This plant modification will provide stops to limit the opening of vent valves CV-10 and CV-116 to 500 from the fully closed position as required by the NRC letter of October 23, 1979. This modification was committed to for the January outage in SCE letter of January 15, 1980, to D. L.

Ziemann of the NRC from K. P. Baskin.

(See Page 3 of letter.)

The reason for this change is to satisfy NRC requirements as stated in NRC letter of October 23, 1979, to "limit the valves to be no more than 300 to 500 open."

2. DESIGN CHANGE 80-04: THE'INSTALLATION OF CONTAINMENT HYDROGEN RECOMBINERS.

(TMI)

(IN PROGRESS)

This plant modification consists of the addition of necessary supports.

for redundantsafety related quality class hydrogen recombiners inside the containment sphere to deal with the long-term post LOCA generation of hydrogen.

The recombiners scheduled to be installed during a projected January 1981 outage will be mounted on steel platforms extended from the A&C steam generator enclosure structures at elevation 53'-6". Access ladders will be provided from the operation deck (el. 42'-0") to the platform for required normal maintenance.

DESIGN CHANGES, 1980

3. DESIGN CHANGE 80-07: ADDITION OF MECHANICAL PENETRATIONS (In Progress)

This plant modification consists of the addition of containment pene trations only, for sampling lines for obtaining samples of the reactor coolant and of the containment atmosphere. The sampling lines and asso ciated systems will be incorporated by a future design change to be pre pared later in 1981.

4. DESIGN CHANGE 80-28: (Revision 2):

POST-ACCIDENT SAMPLING STATION (In Progress)

The purpose of this design change is to provide a shielded underground sample station which will be constructed to house the Post-Accident Sample System. The underground arrangement will minimize personnel expos'ure and preserve space for normal station activities.

5. DESIGN CHANGE 80-30:

INCREASED RANGE OF NOBLE GAS EFFLUENT RADIATION MONITOR (In Progress)

This design change consists of an extended range plant stack effluent radiation monitor that will be capable of measuring post-accident noble gas activity, as Xe-133, from concentrations of ALARA (1 x 10-7 pCi/cc) to 1 x 105 PCi/cc. The system will also provide grab samples for deter mining the 1-131 release.

6. DESIGN CHANGE 80-31:

STEAM DUMP AND SAFETY VALVE HEADER RADIATION MONITORS (In Progress)

This design change adds a radiation monitoring system for the two atmos pheric steam dump valve and steam safety valve headers. The monitors will be installed at the headers'to indirectly monitor the noble gas level by measuring the radiation level of the contained steam to 104 rads per hour with an accuracy of +/- 20 percent. Readout will be provided in the main Control Room and in the Technical Support Center.

0)

DESIGN CHANGES, 1980

7. DESIGN CHANGE 80-32:

ONSITE TECHNICAL SUPPORT CENTER (TMI) (In Progress)

This plant modification consists of the addition of an Onsite Technical Support Center (TSC) located adjacent to the main Control Room in the existing visitors viewing area and a mechanical equipment room on the southeast corner of the administration and control building. The TSC will contain equipment capable of monitoring plant critical functions, and files containing current plant drawings and documents..Operations data will be stored in a moving head disc system.

8. DESIGN CHANGE 80-33: CONTAINMENT PRESSURE INDICATION (In Progress)

Provided by this design change will be new, separate, and redundant containment pressure indicators. The new transducers will tap from the same line as the existing pressure transducers.

Each system will consist of the following components:

Pressure transmitter Signal converter (I/V)

Control Room panel indicating instrument Instrument tubing and valves

9. DESIGN CHANGE 80-36:

REACTOR COOLANT SYSTEM VENTING (In Progress)

This design change consists of a remotely operated system for venting the reactor coolant system during post-accident situations when large quantities of non-condensable gases may collect in reactor coolant system high points. The venting system will utilize existing maintenance vent line stubs.

10. DESIGN CHANGE 80-44: METEOROLOGICAL TOWER MODIFICATIONS (In Progress)

This modification consists of moving the majority of the signal condition ing and recording equipment associated with the meteorological monitoring system from its present location in a room adjacent to the SONGS 1 Control Room to a climate-controlled instrument shelter to be located near the Bluff Meteorological Tower.

DESIGN CHANGES, 1980

11.

DESIGN CHANGE 80-52:

FUEL OIL TRANSFER PUMP DRAINAGE (In Progress)

This design change provides a drainage system (see Figure 1) for the fuel oil transfer pump vaults adequate for the removal of water resulting from any storm, up to and including the PMF, sufficiently rapid to limit the maximum depth of water in the vault to below the fuel oil transfer pump motor coupling. Check valves will be provided in the drain lines to prevent backflow. Curbing at grade will be improved to prevent flood runoff from entering the vaults.
