The Tehran Research Reactor (TRR) is a 5 megawatt-thermal (MWth) pool-type light water research reactor. The United States supplied the TRR to Iran in 1967 and weapon-grade uranium fuel for the reactor.The International Atomic Energy Agency (IAEA) inspects this reactor.ithout notifying the IAEA Iran irradiated uranium oxide (UO2) targets in the TRR and separated plutonium in glove boxes at Tehran Nuclear Research Center (TNRC) laboratories.

The Telecommunication Relay Service (TRS) is a free service that enables persons who are deaf, hard-of-hearing or speech-impaired to use their TDD or TTY to place calls to and receive calls from hearing people. It also enables hearing people to call TDD/TTY users. To use TRS dial 711 (just like you would dial 911 for an emergency). Typed messages from a TDD/TTY are transmitted to a communication assistant who voices them to hearing persons. Hearing persons' messages are voiced to the communication assistant who relays them to the TDD/TTY printout or display. Calls can be placed 24 hours a day, seven days a week.
