The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, Pennsylvania. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the environment. It is the worst accident in U.S. commercial nuclear power plant history. On the seven-point logarithmic International Nuclear Event Scale, the TMI-2 reactor accident is rated Level 5, an "Accident with Wider Consequences".
A torpedo tube is a cylindrical device for launching torpedoes.
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock or minerals from the earth.
Open water diving is underwater diving in an open water environment, where the diver has unrestricted access by way of a direct vertical ascent to the breathable air of the atmosphere. Other environmental hazards may exist which do not affect the classification. Open water diving implies that if a problem arises, the diver can directly ascend vertically to the atmosphere to breathe air, so it is also understood that, with this restriction, a staged decompression obligation is incompatible with open water diving, though it does not affect classification of the environment. This meaning is implied in the certifications titled Open Water Diver and variations thereof.
A sluice is a water channel containing a sluice gate, a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a river sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry.
A water park is an amusement park that features water play areas such as swimming pools, water slides, splash pads, water playgrounds, and lazy rivers, as well as areas for floating, bathing, swimming, and other barefoot environments. Modern water parks may also be equipped with some type of artificial surfing or bodyboarding environment, such as a wave pool or flowrider.
The European Aquatics Championships is the continental Aquatics championship for Europe, which is organised by LEN—the governing body for aquatics in Europe. The Championships are currently held every two years and since 2022, they have included 5 aquatics disciplines: swimming, diving, synchronised swimming, open water swimming and high diving. Prior to 1999, the championships also included water polo, which beginning in 1999 LEN split-off into a separate championships. The open water events are not held during the Olympic year.
Scuba Schools International (SSI) is a for-profit organization that teaches the skills involved in scuba diving and freediving, and supports dive businesses and resorts. SSI has over 3,500 authorized dealers, 35 regional centers, and offices all over the world.
Open water swimming is a swimming discipline which takes place in outdoor bodies of water such as open oceans, lakes, and rivers. Competitive open water swimming is governed by the International Swimming Federation, World Aquatics, except when it is part of multi-sport events, which are governed by the World Triathlon.
An escape trunk is a small compartment on a submarine which provides a means for crew to escape from a downed submarine; it operates on a principle similar to an airlock, in that it allows the transfer of persons or objects between two areas of different pressure.
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. The term embayment is also used for related features, such as extinct bays or freshwater environments.
Advanced Open Water Diver (AOWD) is a recreational scuba diving certification level provided by several diver training agencies. Agencies offering this level of training under this title include Professional Association of Diving Instructors (PADI), and Scuba Schools International (SSI). Other agencies offer similar training under different titles. Advanced Open Water Diver is one step up from entry level certification as a beginner autonomous scuba diver. A major difference between Autonomous diver equivalent Open Water Diver (OWD) certification and AOWD is that the depth limit is increased from 18 to 30 metres.
The International Association for Handicapped Divers is a non-profit organization with its headquarters in Middenmeer, the Netherlands. The organization was established in 1993, with the aim to promote, develop and conduct programs for the training in scuba diving of people with a disability. From 1993 to date (2008) IAHD have educated and certified over 5500 divers and dive professionals worldwide. As the IAHD is a non-profit foundation, all the people on the board are volunteers. There are also volunteers in regions around the world.
The FINA World Open Water Swimming Championships, or more commonly "Open Water Worlds", was a bi-annual FINA championship for open water swimming held in even years from 2000 to 2010, inclusive. Race distances were 5, 10, and 25 kilometers.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
Open Water Diver (OWD) is an entry-level autonomous diver certification for recreational scuba diving. Although different agencies use different names, similar entry-level courses are offered by all recreational diving agencies and consist of a combination of knowledge development (theory), confined water dives and open water dives (experience) suitable to allow the diver to dive on open circuit scuba, in open water to a limited depth and in conditions similar to those in which the diver has been trained or later gained appropriate experience, to an acceptable level of safety.
Open defecation is the human practice of defecating outside rather than into a toilet. People may choose fields, bushes, forests, ditches, streets, canals, or other open spaces for defecation. They do so either because they do not have a toilet readily accessible or due to archaic traditional cultural practices. The practice is common where sanitation infrastructure and services are not available. Even if toilets are available, behavior change efforts may still be needed to promote the use of toilets. 'Open defecation free' (ODF) is a term used to describe communities that have shifted to using toilets instead of open defecation. This can happen, for example, after community-led total sanitation programs have been implemented.
Autonomous diver is an international minimum standard for entry-level recreational scuba diver certification. It describes the minimum requirements for basic training and certification for recreational scuba divers in international standard ISO 24801-2 and the equivalent European Standard EN 14153-2. Various organizations offer training that meets the requirements of the Autonomous Diver standard. A certification which corresponds to Autonomous Diver allows for independent diving with a dive buddy in open water. Most training organizations do not recommend exceeding a depth of 18 or 20 meters at this level of certification. After completion of this certification the training can be extended to a dive leader to ISO 24801-3 or an intermediate not defined by international standards.
Introductory diving, also known as introductory scuba experience, trial diving and resort diving are dives where people without diver training or certification can experience scuba diving under the guidance of a recreational diving instructor. Introductory diving is an opportunity for interested people to find out by practical experience at a relatively low cost if they would be interested in greater involvement in scuba diving. For scuba instructors and diving schools is it an opportunity to acquire new customers. An introductory diving experience is much less time-consuming and costly than the completion of autonomous diver training, but has little lasting value, as it is an experience program only, for which no certification is issued. Introductory scuba diving experiences are intended to introduce people to recreational diving, and increase the potential client base of dive shops to include people who do not have the time or inclination to complete an entry-level certification program.
Recreational diver course referral is a system intended to facilitate completion of training for open water recreational scuba diving students who intend to do their training dives at a place different from the venue for the theory and confined water training. Referral systems within a specific training agency were the original format, but as more universally recognised training standard such as those of the recreational Scuba Training Council, and more recently the ISO and EUF standards have been adopted by most training agencies, it has become possible to expand the system to function across agencies. Referrals within a certification agency are relatively uncontroversial as the agency training standards are expected to be fairly uniform. Cross-agency referrals can occasionally raise problems where the standards differ significantly, as the instructor completing the training may not be entirely familiar with the relevant s requirements.
