Book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1979

Download or read book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1979 written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the third quarter of 1979, the Shippingport Atomic Power Station remained shutdown to complete repairs of the turbine generator hydrogen circulation fan following discovery of a rubbing noise on May 24, 1979. The Station was in a cooldown condition at approximately 180/sup 0/F and 300 psig with a steam bubble in the pressurizer and the reactor coolant pumps in slow speed. The reactor plant cooldown heat exchanger was in service to maintain coolant temperature. The 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops remained in service. All expended PWR Core 2 fuel elements have previously been shipped off-site. The remaining irradiated PWR Core 2 core barrel and miscellaneous refueling tools were in storage under shielding water in the deep pit of the Fuel Handling Building. The LWBR Core has generated 12,111.00 EFPH from startup through the end of the quarter.

Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the fourth quarter of 1979, the Shippingport Atomic Power Station was in operation with the 1A, 1B and 1C loops operating and the Station limited to 70% power. The 1D loop was isolated due to a small primary system coolant leak found on the one inch bonnet vent line on the 1D reactor coolant loop manual isolation valve (05-H6-8). The idle 1D coolant loop was cross connected to the operating 1B coolant loop for pressure control through the purification system inlet valves as per approved operating procedures. The 1AC and 1BD purification loops remained in service.

Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the first quarter of 1979, the Shippingport Atomic Power Station was operating with the 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops in service. The remainder of the expended PWR Core 2 was in storage under shielding water in the deep pit of the Fuel Handling Building. The 1A, 1B, 1C, and 1D 991 psig self-actuated steam relief valves remained gagged during the quarter to prevent leakage through the valve seats. Gagging of redundant relief valves is permitted by ASME Code and approved operating procedures. During the quarter, the Station was operated for Duquesne Light Company system grid including base load and swing load operation. Seven (7) swing load operations were performed on the LWBR Core this quarter to complete the LWBR operating plan of fifty (50) during this operating phase. The LWBR Core has generated 10,771.43 EFPH from startup through the end of the quarter. The generator load factor this quarter was 85%.

Book Shippingport Atomic Power Station Quarterly Operating Report Second Quarter 1979

Download or read book Shippingport Atomic Power Station Quarterly Operating Report Second Quarter 1979 written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the second quarter of 1979, the Shippingport Atomic Power Station remained shutdown for the normally planned semiannual maintenance and testing program, initiated March 23, 1979. The station was in a cooldown condition at approximately 150/sup 0/F and 300 psig with a steam bubble maintained in the pressurizer and the reactor coolant pumps in slow speed. The reactor plant cooldown heat exchanger was in service to maintain coolant temperature. The 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops remained in service. The remainder of the expended PWR Core 2 was in storage under shielding water in the deep pit of the Fuel Handling Building. The 1A, 1B, 1C, and 1D 991 psig self-actuated steam relief valves remained gagged during the quarter to prevent leakage through the valve seats. Gagging of redundant relief valves is permitted by ASME Code and approved operating procedure. The LWBR Core has generated 10,771.43 EFPH from start-up through the end of the quarter.

Book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1978

Download or read book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1978 written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A loss of ac power to the station occurred on July 28, 1978 caused by an interaction between Beaver Valley Power Station and Shippingport Atomic Power Station when the main transformer of Unit No. 1 of the Beaver Valley Power Station developed an internal failure and tripped the BVPS. Two environmental studies were continued this quarter. The first involves reduction of main unit condenser chlorination and the second, river intake screen fish impingement sampling. There were no radioactive liquid discharges from the Radioactive Waste Processing System to the river this quarter. During the third quarter of 1978, 874 cubic feet of radioactive solid waste was shipped out of state for burial. At the end of the quarter, the Fall shutdown continued with the plant heated up, the main turbine on turning gear and plant testing in progress prior to Station startup.

Book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1980

Download or read book Shippingport Atomic Power Station Quarterly Operating Report Third Quarter 1980 written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the third quarter of 1980, the Shippingport Atomic Power Station was operating with the 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops in service. During the quarter, the Station was operated for Duquesne Light Company System grid including base load and swing load operation. Twelve (12) planned swing load operations were performed on the LWBR Core this quarter to complete the LWBR operating plan of fifty (50) during this operating phase. The Station was shutdown on September 12 for the Fall 1980 Shutdown and remained in this mode through the end of the quarter. The LWBR Core has generated 18,297.98 EFPH from start-up through the end of the quarter. There were no radioactive liquid discharges from the Radioactive Waste Processing System to the river this quarter. The radioactive liquid waste effluent line to the river remained blanked off to prevent inadvertent radioactive liquid waste discharges. During the quarter, approximately 0.001 curies of Xe 133 activity were released from the station. The radioactivity released from Shippingport Station is far too small to have any measurable effect on the general background environmental radioactivity outside the plant.

Available in PDF, EPUB and Kindle. Book excerpt: During the third quarter of 1976, the Shippingport Atomic Power Station remained shutdown of PWR/LWBR (Pressurized Water Reactor/Light Water Breeder Reactor) core conversion. The PWR Core has been removed from the reactor vessel and remains in storage in the deep pit of the Fuel Handling Canal. The LWBR core barrel has been installed in the reactor vessel. At the beginning of the quarter the 1A, 1B, 1C and 1D reactor coolant loops were drained with a nitrogen purge established. The 1B, 1C and 1D steam generators were in a wet lay-up condition and recirculating on the reactor plant cooldown and temperature control heat exchanger. The 1A steam generator was in a partial drain condition with a nitrogen purge established. The pressurizer was drained and isolated from the reactor vessel. The preceding plant conditions remained the same throughout the third quarter. The reactor vessel water level was maintained between 706'0'' and 699'6''.
