Space is always at a premium in the design of a power plant, but it seems lack of maneuvering room for steam generator replacement is something every nuclear plant has in common. The project work scope for the new reactor head also included providing new cabling, new cable trays, and a new air-handling unit with all new ductwork. The new steam generators’ instrument tap locations required that new instrument tubing as well as new hangers be installed. Rerouted feedwater piping interfered with existing containment building ventilation ductwork, so that ductwork also required rerouting and new seismically qualified hangers. The upgraded design of the new steam generators required installation of rerouted main feedwater piping, along with new seismically designed hangers, snubbers, and whip restraints. The new reactor vessel head, also fabricated in Spain, was outfitted with new control rod drives in Pennsylvania, transported by barge to Houston, and then trucked to the site. Train tracks to the plant were upgraded to handle the loads because they had not been used since the plant was built. Luminant made its purchase of new steam generators in Spain, transported them by barge to Houston, and then delivered them to the plant by a specially equipped train. Logistical support for nuclear plants is not a U.S.-centric business these days, and the world’s few nuclear-capable manufacturing facilities have plenty of business. As the prime contractor, Bechtel replaced four SGs and a reactor vessel head in Unit 1 during an outage that lasted just 55 days-eight days less than the previous record for a PWR SG replacement outage alone and 10 days under the original aggressive goal set when the project was awarded to Bechtel in 2004. Bechtel Power Corp., working with Luminant, completed a modernization project on Comanche Peak Unit 1 in April 2007 that shattered the record for fastest replacement of aging components at a nuclear power plant.īechtel’s long experience with steam generator (SG) replacements prepared it for perhaps its most ambitious project to date.
COMANCHE PEAK NUCLEAR POWER PLANT UPDATE
I plan to update it to a newer version soon and that update should bring in a bunch of new word senses for many words (or more accurately, lemma).Comanche Peak, Luminant’s (formerly TXU) only nuclear plant, has two 1,150-MW pressurized water reactors (PWRs) that went into service in April 1990 and April 1993, respectively.
COMANCHE PEAK NUCLEAR POWER PLANT CODE
Special thanks to the contributors of the open-source code that was used in this project: the UBY project (mentioned above), and express.js.Ĭurrently, this is based on a version of wiktionary which is a few years old. I simply extracted the Wiktionary entries and threw them into this interface! So it took a little more work than expected, but I'm happy I kept at it after the first couple of blunders.
The researchers have parsed the whole of Wiktionary and other sources, and compiled everything into a single unified resource. That's when I stumbled across the UBY project - an amazing project which needs more recognition. However, after a day's work wrangling it into a database I realised that there were far too many errors (especially with the part-of-speech tagging) for it to be viable for Word Type.įinally, I went back to Wiktionary - which I already knew about, but had been avoiding because it's not properly structured for parsing. This caused me to investigate the 1913 edition of Websters Dictionary - which is now in the public domain. I initially started with WordNet, but then realised that it was missing many types of words/lemma (determiners, pronouns, abbreviations, and many more). The dictionary is based on the amazing Wiktionary project by wikimedia.
And since I already had a lot of the infrastructure in place from the other two sites, I figured it wouldn't be too much more work to get this up and running. I had an idea for a website that simply explains the word types of the words that you search for - just like a dictionary, but focussed on the part of speech of the words. Both of those projects are based around words, but have much grander goals. For those interested in a little info about this site: it's a side project that I developed while working on Describing Words and Related Words.
