With gross electricity generation of 40 12,127,490 MWh and a unit capability of 95.24 %, Unit 2 achieved an 40 excellent operating result in 2018. 20 In the evening hours of 16 September 2018, KKI 2 was the third 20 single block plant worldwide to achieve gross generation of 0 350 billion kWh since its first criticality. In addition, the 250,000 0 generator operating hours were performed on 5 September 2018 at around 7 pm. 100 100 Planned shutdowns 14 to 29 July: Refuelling and annual major inspection with duration 80 of 15.8 days. During the revision 40 new fuel elements were inserted. WANO Review/Technical Support Mission 22 January to 9 February: WANO Peer-Review. Delivery of fuel elements In the reporting year 32 uranium fuel elements from Westinghouse were delivered. 24 uranium fuel elements are in stock at the dry storage. Waste management status Currently 59 CASTOR © V-casks (26 units CASTOR © V/19, 26 units of CASTOR © V/52 (85-type) and 7 TN © 24E-casks) are stored in the on-site intermediate storage BELLA. The interim storage facility was taken over by BGZ Gesellschaft für Zwischenlagerung mbH on 1 January 2019. The completion of the project “Structural optimisation of the KKI BELLA warehouse” was in November 2018. 60 Unplanned shutdowns and reactor/turbine trip 340August : On 3 August at 01:29 a.m. the plant had to be taken off the grid due to a repair of a drainage valve. At 07:32 p.m. the mains was switched back. 20 Power 0 reductions above 10 % and longer than for 24 h None. Safety Reviews 21 February: Management evaluation KKI. 1 March: Positionierung: Company review. 13 and Bezug, 15 March: links, Inspection unten in accordance with §16 Störfall Verordnung – Brandschutz und Immissionsschutz (Major Accidents Ordinance – Fire Protection and Immission Control). 13 to VGB: 16 March: HKS6K 2 nd Periodic 30 % Audit by DNV GL Business Assurance Zertifizierung atw: 100 & Umweltgutachter 60 0 0 GmbH according to DIN EN ISO 9001:2015 / 14001:2015, BS OHSAS 18001:2007 and EMAS. 12 to 13 June: Internal “Audit Plant Monitoring” at KKI. 7 August: Management system, status discussion. 27 September: 2 nd operational review KKI (half-year review 2018). 4 to 10 October: Management system audit. 7 and 8 November: Internal Audit “Processing and Execution of Projects”. X = 20,475 Y = 95,25 B = 173,5 H = 38,2 General points A grid failure on 8 April 2018 (2-pole short-circuit on a 400 kV line) led to repercussions via the neighbouring Ottenhofen switching plant to the plant. Numerous consumers were briefly switched off via undervoltage monitoring. A voltage drop to 9 kV occurred on the 10 kV bus. Many of the consumers switched on again automatically. The voltage drop had no influence on the system performance and did not lead to any tripping in the block protection and safety system. Emergency exercise with expert ESN on 27 November 2018: The exercise began outside working hours. The scenario assumed was a “station black out”, fire alarm in the emergency food building and failure of various emergency measures. The emergency exercise was completed professionally and purposefully with a highly motivated team. Report Operating Results 2018
