What has now become of Chernobyl disaster

Many of you have heard what happened in Chernobyl- located North of Kiev, Ukraine and near the south border of Belarus. I was born in the year 1986- when it happened and always interested in the history of my country. (Russia).

Here is a script of what exactly happened from:

The interaction of very hot fuel with the
cooling water led to fuel fragmentation along with rapid steam production and
an increase in pressure. The design characteristics of the reactor were such
that substantial damage to even three or four fuel assemblies can – and did –
result in the destruction of the reactor. The
overpressure caused the 1000 t cover plate of the reactor to become partially
detached, rupturing the fuel channels and jamming all the control rods, which
by that time were only halfway down. Intense steam generation then spread
throughout the whole core (fed by water dumped into the core due to the rupture
of the emergency cooling circuit) causing a steam explosion and releasing
fission products to the atmosphere. About two to three seconds later, a second
explosion threw out fragments from the fuel channels and hot graphite. There is
some dispute among experts about the character of this second explosion, but it
is likely to have been caused by the production of hydrogen from
zirconium-steam reactions.
graphite (about a quarter of the 1200 tones of it was estimated to have been
ejected) and fuel became incandescent and started a number of fires,
causing the main release of radioactivity into the environment.”

Going Green- Good or Bad for the Valve Market?

I always wonder about the term Going Green. This morning we received our Office Supply order and it was in a big green bag instead of the boxes they usually use.  Another one I noticed is that we rely on e-mails more than snail mail for information. The greener we go, does it mean the fewer valves will be needed in the Pulp and Paper industry?  I found this interesting article at, and this one paragraph caught my eye below:

“Perhaps no manufactured product plays a more significant role in everyday human activity than paper and paper products. Paper provides the means for recording, storing and disseminating most of today’s information. Even though people have extolled the coming of the paperless society, it has not yet arrived. Humans still print e-mails and other correspondence and information they get from the paperless communication channels of the computer and the Internet. And beyond that, paper is the most widely used wrapping and packaging material as well as a critical component today in everyday life. From drywall to napkins to office supplies, paper is used for many purposes, and that situation won’t change for a long, long time.”

Going Green with Valves

“Valves are often chosen by a mill based on how they can handle these challenges. In high-scaling applications, where the media sticks to the surface of the valve, for example, most plants will consider a ball valve first. This is because these valves offer full flow characteristics. The pulp and paper industry has hit the doldrums, but they still require valves to keep the mills operational. With the state of the industry, mills will be looking to purchase high-quality valves from people with an idea where the valves are used and how to apply them properly.”


Proposed ASTM Standard Facilitating Compliance with Greenhouse Gas Regulations

The need for a consensus standard targeting the measurement of gaseous hydrocarbons and other components of gaseous streams allowing users to better comply with U.S. Environmental Protection Agency’s greenhouse gas regulation provided the impetus for the development of a proposed new ASTM International standard meeting this need.

ASTM WK33788, Test Method for Determination of Hydrocarbons and Nonhydrocarbon Gases in Gaseous Mixtures by Gas Chromatography, is under development by Subcommittee D03.07 on Analysis of Chemical Composition of Gaseous Fuels, part of ASTM International Committee D03 on Gaseous Fuels.

According to Shannon Canfield, marketing chemist, Wasson-ECE Instrumentation, and chairman of D03.07, ASTM WK33788 is a merging and enhancement with updated technology of two ASTM standards, ASTM D1945, Test Method for Analysis of Natural Gas by Gas Chromatography, and ASTM D1946, Practice for Analysis of Reformed Gas by Gas Chromatography.

“ASTM D1945 and ASTM D1946 will remain on the books as the natural gas industry uses them just as they are written,” says Canfield. However, Canfield notes that many users perform gaseous fuel hydrocarbon analyses using hardware and technology such as capillary columns and various detectors that are not included in D1945 and D1946.

“In order to comply with what is being used in the industry and to provide regulators with a more comprehensive method to point to, we decided to develop ASTM WK33788,” says Canfield.

The proposed new standard will cover the analysis of parts per million to percent level inert gases such as hydrogen, oxygen, argon, nitrogen, carbon monoxide and carbon dioxide along with low ppm level hydrocarbons such as methane, ethane and propane in various gaseous streams. The proposed new standard is intended to be performance based. The methodology described in the proposed standard enables separation of low molecular weight hydrocarbons and inert gases for a detailed analysis of the composition of gaseous streams.

Refineries and chemical plants, along with contract laboratories and regulatory agencies, will be the primary users of ASTM WK33788.  All parties interested in aiding the development of gaseous fuels standards are encouraged to join Committee D03.

ASTM International welcomes and encourages participation in the development of its standards. For more information on becoming an ASTM member, visit
