Previously, the damage to reactors at the plant, 137 miles north of Tokyo, has been rated at level 5 on the scale, putting it on a par with the Three Mile Island accident in the United States in 1979. The government elevated the disaster by two notches, a rating that has previously only been applied to the Chernobyl accident in 1986.

The government’s decision is based on a preliminary calculation by the Nuclear Safety Commission of Japan.

The safety agency, a government body, estimates the amount of radiation released to be 370,000 terabecquerels. One terabecquerel is a trillion becquerels, the standard measure of radiation.

Japan’s safety commission, an quasi-independent panel of experts advising the government, estimates the total amount emitted is much higher, at 630,000 terabecquerels. The permissible level of iodine-131 for vegetables and fish is 2,000 becquerels per kilogram.

The agency also said radiation beyond the amount considered safe for humans during a full year had been detected up to 37 miles northwest of the plant and 24 miles to the southwest, well beyond the 18-mile exclusion zone the government has imposed around the nuclear plant.

FISHER CAPITAL MANAGEMENT INVESTMENT: Triad Boiler Room Systems Launched New Commercial Boilers

Benefits of Modularity
TRIAD's elegantly simple design maintains consistent water volume where heat is required.

• Boilers are activated sequentially, drawing water from the main loop into the next hot water boiler until the heating need is meet.
• firing boilers remaining isolated, so no heated water circulates through cold boilers.
• During most of the year the unfired boilers provide additional backup.
• Outdoor temperatures and loop water temperatures are constantly monitored.

Fisher Capital on Boiler Room Equipment, Inc: The efficiency of this design is most apparent during warmer months, when a conventional hydronic heating or steam boiler could still be operating at full capacity.

Primary-Secondary Piping
TRIAD integrates modularity with a single pipe primary-secondary system. TRIAD was the first company to employ a Primary-Secondary concept. It operates with two loops, (i) the primary loop, or building main loop, and (ii) smaller secondary loops off of each hot water boiler, which supply heated water to the primary loop.

Upon a call for heat, the boiler pump begins pushing the return water into the boiler and out through the secondary loop, supplying this hot water up into the primary loop (the main header), where it mixes with the cooler return water from the main loop of the building.

• Supply and return water are blended, avoiding the need for expensive and unreliable mixing valves commonly used in two pipe systems.
• The secondary loop isolates each hot water boiler, resulting in a very efficient system that minimizes thermal shock.

Control Panel
TRIAD Boilers can be sequenced by the use of our control panel that provides many attractive features:

• Temperature set-back when less heat is required, such as nights and weekends.
• Adjustments for latent heat, to take advantage of hot boiler water that retains heat after the burner shuts down.
• Outdoor reset based on atmospheric temperatures.
• Monitoring of return water temperatures to maintain accurate heating output.

It is also very easy to sequence our boilers using the panel of any other major manufacturer.

Packaged ProductFisher Capital on Boiler Room Equipment, Inc: All TRIAD hot water boilers and steam boilers are fully assembled, packaged products, which offer several advantages over boilers that must be assembled at the jobsite

• Onsite labor costs are minimized.
• Quality control is higher at the factory than at the jobsite
• The ease of installation of a packaged boiler allows for quicker start up.
