  • PAGE 1 OF 11 l RANCIIO SECO ANNUAL REPORT Shutdown Statistics: l The District provides the following shutdown statistics:
1. Rancho Seco permanently shut down nuclear power operations on June 7,1989.

l

2. The Rancho Seco reactor has been completely defueled since December 8,1989. l i 3. The Rancho Seco Spent Fuel Pool (SFP) contains 493 spent fuel assemblies and is  :

. licensed for 1080 spent fuel assembhes.

J l 4. The NRC amended the Rancho Seco operating license to Possession-Only status on March 17,1992. I 2

5. Rancho Seco has been in the Permanently Defueled Mode (PDM) during the entire l reporting period (May 7,1996, through May 6,1997),

i i

6. The NRC isnued Rancho Seco a Decommissioning Order on March 20,1995. The  ;

4 Order (1) authorized the District to decommissioning Rancho Seco and (2) accepted 1 the Rancho Seco Decommissioning Funding Plan.

4 7. The District revised the originally NRC-approved Rancho Seco Decommissioning  ;

Plan (RSDP) in November 1996, to address immediate incremental decommissioning activities and converted the RSDP to the Post Shutdown Decommissioning Activities Report (PSDAR) in March 1997, pursuant to the PSDAR content l requirements contained in the new 10 CFR 50.82 regulations.

)

8. Rancho Seco personnel completed the spent fuel assembly inspection program in {

June 1996, and identified the spent fuel assemblies that meet the District failed fuel i criteria in preparation for the fuel off-load project. The District identified and verified that nine spent fuel assemblies met the District's failed fuel criteria. The District will place failed fuel assemblies in a special failed fuel dry storage canister.

9. On February 28,1997, the District took the Component Cooling Water (CCW)

System out of service to perform maintenance. The CCW system is a support system 3

for the Spent Fuel Cooling system. The CCW system was returned to service on 3

March 7,1997. During the seven day CCW system outage, the Spent Fuel Pool (SFP) water temperature increased from 61 *F to approximately 78 *F.

I I

PAGE 2 OF 11

. RANCIIO SECO ANNUAL REPORT Shutdown Statistics:(Continued)

10. During and following the CCW system outage, the SFP leak rate through the leak chase system increased from its approximately steady state rate of about 35 gallons per day to a high of approximately 48 gallons per day. The leak rate then slowly decreased back to approximately 35 gallons per day by the end of the reporting period. The District believes this small change in leak rate is directly related to the change in SFP water temperature.

l The District intends to remove all the spent fuel assemblies from the SFP startmg m 1998, and place the fuel in dry storage at an on-site Independent Spent Fuel Storage Installation (ISFSI) licensed pursuant to 10 CFR 72. The District then intends to drain and process the SFP water following spent fuel assembly removal.

~

Monitoring," installs: (1) A thermocouple on each HSM to provide temperature data on the plant computer system; (2) Two pressure indicators that provide the capability to ,

monitor pressure of a dry storage cask that would be used for long term storage of a  !

I breached dry shielded canister; and (3) A fire protection panel and an ionizing smoke detector in the ISFSI electrical building. This design change is required to support dry fuel storage at the Rancho Seco ISFSI. This design change will require a change to the DFPP

and the ISFSI Safety Analysis Report (SAR), which are LBDs, but will not require a change to any other LBD.

Dwign Change Package R91-0001 AC, Revision 2, "Ilorizontal Storage Module

! (LUM) Temperature Monitoring System and Dry Storage Cask Pressure 4

Momtoring," makes small corrections to DCP R97-0001 AC, Revision 1, by assigning a fire zone number to the ISFSI fire protection system and correcting a few typographical

errors. This design change revision will require a change to the DFPP, which is a LBD, but

! will not require additbnal changes to any other LBD.

4 Design Change Package PJ4-0002, Revision 0, " Plant Integrated Computer System," combines the functions of the IDADS, Bailey, and DRMS computers and annunciator window systems into a Personal Computer based plant computer system. This modification will not change the type or amount ofinformation that is available to operators in the control room. This design change will require changes to the DSAR and required a change to the Decommissioning Plan (now the PSDAR), which are LBDs, but will not require a change to any other LBD.

Design Change Package R94-0010, Revision 0," Isolate CO2 Fire Protection System in Bruce GM Diesel Generator Rooms," removes the fire detection and suppression equipment from the Bruce GM diesel generator rooms. The Bruce GM diesel generators were previously removed in accordance with the Asset Recovery Program. This design change requires a change to the DFPP, which is a LBD, but will not require a change to any other LBD.

Design Change Package R96-0003, Revision 0, " Reconfigure the 125 Volt DC and 120 Volt AC Supply System to Consolidate Loads and Eliminate Unnecessary Electrical Buses," removes four 125 volt de and one 120 volt ac electrical distribution .

panels and consolidates necessary loads on other electrical distribution panels. The reconfigured panels will continue to carry loads well below their design rating. This design change will require changes to the Defueled Safety Analysis Report (DSAR), which is a LBD, but will not require a change to any other LBD.

. RANCIIO SECO ANNUAL REPORT l 10 CFR 50.59(b) Summarv;(Continued)

Design Change Package R97-0002, Revision 0, " Installation of Two Impact Limiters in the Fuel Storage Building," installs one impact limiter in the spent fuel poci cask ,

loading pit and one impact limiter under the spent fuel pool cask loading pit shelf from the .

] upender pit area. The impact limiters are considered heavy loads and will be installed in accordance with the District's NUREG-612 heavy load control program. This design change will require changes to the DSAR, which is a LBD, but will not require a change to any other LBD. i l

l Design Change Package R97-0003, Revision 0, " Isolate Portions of Turbine Plant l Cooling Water (TPCW) System," isolates portions of TPCW connected to equipment j that is not operated nor required to function during the Permanently Defueled Mode

(PDM). Isolation of this equipment makes it available for dismantlement in accordance i

with the Incremental Decommissioning Action Plan. This design change will require a ,

change to the DSAR, which is a LBD, but will not require a change to any other LBD.

1 Design Change Package R97-00ll, Revision 0, " Isolate Operating Systems Connected to Auxiliary Boilers " isolates the Diesel Fuel Oil, Instrument Air, Service

Water, Service Air, Auxiliary Steam, and Fire Protection Systems from the Auxiliary Boilers, which is not operated nor required to function during the Permanently Defueled Mode (PDM). Isolating the Auxiliary Boilers makes them available for disrnantlement in

! accordance with the Incremental Decommissioning Action Plan. This design change will  !

l require a change to the DSAR and ODCM, which are LBDs, but will not require a change  !

to any other LBD.

i Deviation from Quality (DQ) 96-0078, " Fuel Storage Building (FSB) Supply Fan

{- Capacity Discrepancy," identified a discrepancy between the actual, rated FSB supply fan capacity and what design documents indicate. The DSAR indicates the FSB supply fan

, capacity is 10,500 cfm, while the actual fan capacity has always been 6,100 cfm. The DSAR requires revision to reflect the actual FSB supply fan capacity. The actual lower capacity j has no impact on any analyzed accidents or Spent Fuel Pool (SFP) heat-up analyses. The i

fuel handling accident assumes a default FSB exhaust flow with no reliance on supply flow.

The SFP heat-up analysis assumes a minimum supply flow of 5,000 cfm. The supply fan

] continues to meet its intended function and surveillance requirements. This DQ resolution requires a change to the DS AR, which is a LBD, but does not afTect any other LBD.

Dry Fuel Storage Equipment Operator Training and Certification Program, dated August 21,1996, defines the program the District will use to provide initial training, test, and certify Dry Fuel Storage (DFS) Equipment Operators. This program is required to support dry fuel storage at the Rancho Seco ISFSI. The District will qualify DFS Equipment Operators to operate equipment used to move spent fuel assemblies,i,n a cask a

10 CFR 50.59(b) Summarv:(Continued) and/or canister from the spent fuel pool to the ISFSI for dry storage. Also, DFS

Equipment Operators will be qualified to retrieve spent fuel assemblies from the ISFSI, if ,

ever necessary. The District added this program to the ISFSI SAR as Appendix A. Since the ISFSI SAR is considered a LBD, this program constitutes a change to a LBD, but the program does not require a change te any other LBD.

Incremental Decommissioning Act3.on Plan, Revision 0, describes the District's plan to i dismantle slightly and non contaminated systems and components and dispose oflow level l radioactive waste now instead of waiting until the year 2008. The District determined implementing incremental decommissioning now will substantially reduce radioactive waste disposal costs associated with decommissioning. This action plan requires a change to the Rancho Seco Post Shutdown Decommissioning Activities Report (formerly the Rancho i Seco Decommissioning Plan), which is a LBD, but does not require a change to any other 4

LBD.

i Rancho Seco Post Shutdown Decommissioning Activities Report (PSDAR),

Amendment 1, revised the Rancho Seco Decommissioning Plan (RSDP; the original

. PSDAR) to conform with the PSDAR content requirements specified in the new 10 CFR 50.82 regulations. The information required in the PSDAR is much less than was contained d in the RSDP. PSDAR, Amendment 1, contains a description of planned deconunissioning

, activities, a schedule of activities through license termination, an estimate of expected costs, and a discussion of environmental impacts. This change is a change to the PSDAR and requires a change to the DSAR, which are LBDs, but does not affect any other LBD.

i Procedure CAP-0002, Revision 8, "OIT-site Dose Calculation Manual (ODCM),"  ;

increased the Auxiliary Building Grade Level Vent (ABGLV) default flow rate to 31,000 cfm in accordance with the resolution to DQ 96-0055. This ABGLV default adjustment changed the total site default gaseous efnuent flow rate to 152,740 cfm. This change is a change to the ODCM and requires a change to the DSAR, which are LBDs, but does not 4

require a change to any other LBD.

Procedure RSAP-0101, Revision 22, " Organization, Responsibilities, and Authorities," changed the District corporate nuclear organization in accordance with a District re-organization. The Rancho Seco related Deputy AGM, Operations functions are now performed by the Director, Power Generation. The Rancho Seco related AGM &

Chief Operations Officer functions are now performed by the AGM Energy Supply & Chief Engineer. This organization change requires a change to the DSAR, which is a LBD, but l does not require a change to any other LBD. 1 1

Procedure RP.309.II.02, Revision 5, " Radioactive Material Packaging and i Container Selection," changed the criteria for determining when and how to assign a proper container identification number. Also, made several editorial changes. This procedure change requires a change to the DSAR, which is a LBD, but does not require a change to any other LBD.

Radiological Environmental Monitoring Program (REMP) Manual, Revision 9, changed the Land Use Census radius from five miles to two miles and frequency from 'l annual to biennial. The reason for a five mile radius was mainly for identification of milk animals and gardens. But, the REMP does not require milk sampling and assumes a -

default milk animal resides at the site boundary, which is much closer than five miles. Also, the REMP garden is maintained at the site boundary. The changes provide assurance the Rancho Seco REMP will continue to represent an environmental sampling program that meets the intent of applicable regulations and regulatory guidance and provides for accurate l assessment of the radiological environment in and around the Rancho Seco site. This  !

change directly affected the REMP Manual and requires a change to the DSAR, which are j LBDs, but does not affect any other LBD.  ;

Software Change Request CSCR 3794, " Delete Computer Point R430 from IDADS/  !

Bailey and Radiation Assessment Coordinator (RAC) Display," removes the Fuel Storage Building area radiation monitor R-15028 IDADS/ Bailey computer point readout and RAC display. Remaining local and remote radiation readouts are sufficient to monitor and assess radiation levels in the Fuel Storage Building. This software change requires a change to the DSAR, which is a LBD, but does not require a change to any other LBD.

Special Test Procedure STP-1339, Revision 0, " Plant Integrated Computer System (PICS) Test," demonstrates the ability of PICS to monitor defueled plant operating parameters and provide necessary information and alarms to the plant operators. The test is not described in the DSAR, but does not constitute an Unreviewed Safety Question. This special test procedure does not require a change to any LBD.

Special Test Procedure STP-1340, Revision 0, "HSM Temperature Monitoring System.," verifies that the HSM Temperature Monitoring System thermocouples are functional and that the system is properly tied in to the Plant Integrated Computer System.

This test is necessary to support dry fuel storage at the Rancho Seco ISFSI. The test is not I described in the DSAR, but does not constitute an Unreviewed Safety Question. This l special test procedure does not require a change to any LBD. l

Special Test Procedure STP-1341, Revision 0, " Gantry Crane Radio Control Reliability," tests modifications made to the Gantry Crane using the new radio controllers.

The two radio controllers will be used to move the Gantry Crane for approximately twelve hours each. The Gantry Crane movements will simulate cask movements that is equivalent j to approximately the filling and transport of four casks of spent fuel assemblies. This test is l necessary to support dry fuel storage at the Rancho Seco ISFSI. The test is not described in I the DSAR, but does not constitute an Unreviewed Safety Question. This special test procedure does not require a change to any LBD.
