Subject field(s)
  • Nuclear Plant Safety
CONT

An ex-vessel steam explosion may occur if the primary system is breached by hot debris. Debris in the reactor outlet piping may fail the piping and fall onto the pump room floor or debris on the reactor vessel bottom may be blocked from flowing into the outlet piping if it freezes in the effluent piping nozzle muff structure. If this occurs, the debris will heat up on the reactor vessel bottom and eventually fail the bottom shield. The likely mode of failure of the bottom shield is collapse of the shield as a whole. If it collapses, the entire shield, as well as the molten debris, will fall into the pin room below the reactor vessel. The debris will then flow across the floor into the pump room. In either event, a large portion of the reactor fuel inventory will be deposited on the pump room floor. The pump room floor will be covered with water in many scenarios. A steam explosion may result when the debris enters this water.

CONT

La condition nécessaire à une explosion vapeur est le simple contact entre les deux fluides, mais les situations les plus énergétiques sont celles où les deux fluides sont mélangés avant que ne se déclenche la fragmentation. Dans les réacteurs à eau pressurisée de tels mélanges pourraient se former après la fusion du cœur lors de la relocalisation du corium en fond de cuve (explosion en cuve) et/ou éventuellement lors de la percée de la cuve et la chute du corium dans le puits de cuve (explosion hors cuve).

Subject field(s)
  • Orbital Stations
CONT

The first segment to be launched into orbit, designated Z1, will not permanently attach to other truss segments. The Z1 segment is a 10 ft(3 m) cubelike truss made from six machined bulkheads that are bolted together. The truss houses four control moment gyroscopes that form part of the guidance, navigation, and control system. The location of Z1 is nearly in the middle of the station, which makes it an ideal location for the gyroscopes. A micrometeor shield composed of three sheets of 0. 25 in.(6 mm) aluminum about 5 in.(127 mm) apart protects the sensitive gyroscopes from debris. The 18, 300 lb(8, 300 kg) Z1 segment is currently scheduled to be launched by the end of this year. The truss is a transitional structure that will connect to the pressurized Unity module already on orbit. Astronauts will tighten 16 motorized bolts on the circular coupling on the Unity module side into nuts on Z1 and connect the associated utility plug-ins. Pressurized units generally have circular couplings and nonpressurized unit connectors are rectangular.

CONT

The Z1 truss segment is equipped with several spacewalk aids: Two EVA tool stowage devices (ETSDs), 22 worksite interface (WIF) sockets, 1 flight-releasable grapple fixture (FRGF), 11 trusses, 2 tray launch restraints, numerous standard handholds and handrails, and several custom handles.

OBS

The first piece of truss structure - we refer to it as the Z1 Truss because it is the zenith or uppermost - will be on the uppermost part of the station or the top; the zenith.

OBS

Z1 truss; integrated truss structure Z1; Z1; ITS-Z1: terms and abbreviations officially approved by the International Space Station official approval Group (ISSOAG).

PHR

[...] l'élément de structure Z1 [est une] pièce unique en son genre. Il s'agit d'un élément de structure externe à l'intérieur duquel se trouvent des gyroscopes et du matériel de télécommunication et qui servira plus tard de plate-forme de montage des immenses panneaux solaires qui alimenteront la Station spatiale internationale en électricité.

CONT

Z1 est une plate-forme de communication [qui] supporte des systèmes de communication en bande Ku et S. Le système en bande Ku permet une transmission de données à haut-débit vers le sol, à la vitesse de 50 Mbps Mégabits par secondes). C'est suffisant pour transmettre 4 signaux vidéo en même temps. Ce système servira donc pour la liaison télévisée, mais aussi pour le fret à bord.

  • Orbital Stations
CONT

Kibo's Debris Shield. The International Space Station(ISS) wall is designed to protect the ISS and its crew from space debris. A debris shield is adopted for this particular purpose. A famous astronomer, Fred Whipple, devised this shield, so it is called a Whipple Shield. The idea is to attach a layer of thin aluminum plate outside the wall. When a space debris impacts this outer plate, the kinetic energy of the space debris is converted to heat. This heat creates a hole in the outer plate. However, the debris will evaporate or disintegrate to small particles consisting of gas, liquid and solids and will no longer be able to significantly damage the wall.... a stuffed-shield is adopted on the wall of the front side of Kibo, covering an area of 150 degrees. A stuffed shield binds several kinds of textile layers similar to a bulletproof vest between itself and the wall. This is a reinforced Whipple shield.

OBS

The International Space Station will be covered by 200 different types of protection.

[...] Dans le cas des modules d'habitation, le bouclier multi-couches [...] est maintenu à plusieurs centimètres de la surface de la paroi [pour une protection accrue].

DEF

... protection where pipeline coatings are subjected to rocky terrain, mountain handling, excessive abrasion and damaging backfills.

CONT

Pipe Saver Rock Shield helps maintain cathodic flow in natural gas and oil pipelines. The durable plastic mesh is wrapped around the pipe to protect against debris and rock damage during back filling and against problems that certain soil conditions can cause after pipe is installed.

CONT

Rockshield Testing. Description. Tuff-N-Nuff is a non-woven mat consisting of small diameter (approximately 0.050") strands of PVC. The strands are bonded to each other in a controlled random pattern. The rock shield protects pipe coatings from direct impact during backfilling operations. It also provides long term protection by keeping hard objects in the backfill away from the pipe coating during operation of the line. Pipe may move laterally as well as longitudinally, and the rock shield is the first line of defense against damage to the coating and the pipe.

CONT

Rock shield for pipeline construction.
