7.8(3)(a) Summary of Plant Operations During the period January 1, 2004 through December 31, 2004 the reactor was critical for 4535 hours0.0525 days <br />1.26 hours <br />0.0075 weeks <br />0.00173 months <br /> with an energy output of 90,419 MWH. Major activities during this period included: requalification of 21 licensed operators; the licensing of a new senior reactor operator; and shipment of radioactive waste.
7.8(3)(b) Unscheduled Shutdowns
- 1. There were 5 scrams due to commercial power interruptions. After 4 of those scrams, a return to 20 MW occurred within an hour. For the other scram, a restart to 20 MW occurred within 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />.
7.8(3)(c) Tabulation of Major Items of Plant Maintenance Note: Some of these items may be also listed as Engineering Change Notices (ECN).
- 1. Replaced thermal shield pump piping and associated valves.
- 2. Replaced three secondary cooling pumps and associated valves.
- 3. Replaced secondary pump motors for #5 and #6 pumps.
- 4. Replaced storage pool shell-and-tube heat exchanger (HE-8) with stainless steel plate-and-frame heat exchanger.
- 5. Refurbished sealing surfaces for all shim arm (control rods) drive shaft seals.
- 6. Replaced all four shim arms.
- 7. Replaced heavy water inventory.
- 8. Replaced valve disks for main primary pump discharge valves.
- 9. Replaced intermediate and power range nuclear instrumentation.
- 10. Cut 32 spent fuel elements in preparation for shipments.
- 11. Made a low-level radioactive waste shipment..
- 12. Instrument calibration surveillance tests were performed for the following:

- 13. Twenty instrument service requests (ISR) were completed, including:
ISR # ACTION 1665 Replaced detector for PT-8 Process Room area radiation monitor 1669 Replaced detector tube in RM 3-2 Fission Products radiation monitor 1671 Replaced valve positioner for DWV-39 7.8(3)(d) Tabulation of Major Changes in the Facility and Procedures, and Tests and Experiments, Carried Out Without Prior Approval by the NRC pursuant to 10 CFR 50.59.
The following facility changes were completed this year. None required a license amendment or a change to the technical specifications, and there were no changes made pursuant to the applicable criteria of 10 CFR 50.59.
462 Convert beam tube shutter-controls/shutters to air-to-open, vent-air-to-close 466 Installation of additional sensor/alarm for emergency light water cooling supply 469 Replace storage pool heat exchanger and piping 470 13% scram trip removed with upgrade to wide range nuclear channels 471 Thermal Shield pumps replaced with smaller pumps equipped with variable-frequency AC drives 472 Individual Intermediate Range and Power Range L & N Nuclear Channels replaced with combined Gamma Metrics Wide Range Nuclear Channels 7.8(3)(e) Summary of Radioactive Material Released and Results of Environmental Surveys Performed.
Gaseous releases consisted of 1358 curies of tritium, 947 curies of Argon-41, 0.03 curies of Br-82, and 0.05 curies of other beta-gamma emitters. There were 4.87 curies of tritium and 1.4 millicuries of other beta-gamma emitters released into the sanitary sewer. Environmental samples of the streams, vegetation, and/or soil, and air showed no significant changes.
