1986


In 1986, Congress reformed U.S. immigration laws to preserve the tradition of legal immigration while seeking to close the door to illegal entry. The employer sanctions provisions, found in section 274A of the Immigration and Nationality Act (INA), were added by the Immigration Reform and Control Act of 1986 (IRCA). These provisions further changed with the passage of the Immigration Act of 1990 and the Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA) of 1996.

This handbook will tell you how to properly complete Form I-9, which helps you verify that your employees are authorized to work in the United States. You must complete a Form I-9 for every new employee you hire after Nov. 6, 1986, as well as new employees hired in the Commonwealth of the Northern Mariana Islands (CNMI) on or after Nov. 28, 2009. This includes U. S. citizens and noncitizen nationals who are automatically eligible for employment in the United States.


Form I-9, Employment Eligibility Verification, requirements come out of the Immigration Reform and Control Act of 1986 (IRCA). IRCA prohibits employers from hiring and employing an individual for employment in the U.S. knowing that the individual is not authorized with respect to such employment. Employers also are prohibited from continuing to employ an individual knowing that he or she is unauthorized for employment. This law also prohibits employers from hiring any individual, including a U.S. citizen, for employment in the U.S. without verifying his or her identity and employment authorization on Form I-9.


Prohibits employers from knowingly hiring unauthorized aliens and hiring individuals without completing the employment eligibility verification process. This act led to creation of Form I-9, Employment Eligibility Verification. All employers must use Form I-9 for all employees hired on or after Nov. 6, 1986, who are working in the U.S. This act also established prohibitions against national origin and citizenship or immigration status discrimination with respect to hiring, firing and recruitment or referral for a fee.


The Electronic Communications Privacy Act and the Stored Wire Electronic Communications Act are commonly referred together as the Electronic Communications Privacy Act (ECPA) of 1986. The ECPA updated the Federal Wiretap Act of 1968, which addressed interception of conversations using "hard" telephone lines, but did not apply to interception of computer and other digital and electronic communications. Several subsequent pieces of legislation, including The USA PATRIOT Act, clarify and update the ECPA to keep pace with the evolution of new communications technologies and methods, including easing restrictions on law enforcement access to stored communications in some cases.


The April 1986 disaster at the Chernobyla nuclear power plant in Ukraine was the product of a flawed Soviet reactor design coupled with serious mistakes made by the plant operatorsb. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture.


The next task was cleaning up the radioactivity at the site so that the remaining three reactors could be restarted, and the damaged reactor shielded more permanently. About 200,000 people ('liquidators') from all over the Soviet Union were involved in the recovery and clean-up during 1986 and 1987. They received high doses of radiation, averaging around 100 millisieverts (mSv). Some 20,000 liquidators received about 250 mSv, with a few receiving approximately 500 mSv. Later, the number of liquidators swelled to over 600,000, but most of these received only low radiation doses. The highest doses were received by about 1000 emergency workers and onsite personnel during the first day of the accident.


According to the most up-to-date estimate provided by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the average radiation dose due to the accident received by inhabitants of 'strict radiation control' areas (population 216,000) in the years 1986 to 2005 was 31 mSv (over the 20-year period), and in the 'contaminated' areas (population 6.4 million) it averaged 9 mSv, a minor increase over the dose due to background radiation over the same period (about 50 mSv)4.


Several organizations have reported on the impacts of the Chernobyl accident, but all have had problems assessing the significance of their observations because of the lack of reliable public health information before 1986.


In 1989, the World Health Organization (WHO) first raised concerns that local medical scientists had incorrectly attributed various biological and health effects to radiation exposureg. Following this, the Government of the USSR requested the International Atomic Energy Agency (IAEA) to coordinate an international experts' assessment of accident's radiological, environmental and health consequences in selected towns of the most heavily contaminated areas in Belarus, Russia, and Ukraine. Between March 1990 and June 1991, a total of 50 field missions were conducted by 200 experts from 25 countries (including the USSR), seven organizations, and 11 laboratories3. In the absence of pre-1986 data, it compared a control population with those exposed to radiation. Significant health disorders were evident in both control and exposed groups, but, at that stage, none was radiation related.


Ukraine depends upon, and is deeply in debt to, Russia for energy supplies, particularly oil and gas, but also nuclear fuel. Although this dependence is gradually being reduced, continued operation of nuclear power stations, which supply half of total electricity, is now even more important than in 1986.


Chernobyl unit 4 was enclosed in a large concrete shelter which was erected quickly (by October 1986) to allow continuing operation of the other reactors at the plant. However, the structure is neither strong nor durable. The international Shelter Implementation Plan in the 1990s involved raising money for remedial work including removal of the fuel-containing materials. Some major work on the shelter was carried out in 1998 and 1999. About 200 tonnes of highly radioactive material remains deep within it, and this poses an environmental hazard until it is better contained.


The New Safe Confinement (NSC) structure was completed in 2017, having been built adjacent and then moved into place on rails. It is an arch 110 metres high, 165 metres long and spanning 260 metres, covering both unit 4 and the hastily-built 1986 structure. The arch frame is a lattice construction of tubular steel members, equipped with internal cranes. The design and construction contract for this was signed in 2007 with the Novarka consortium and preparatory work onsite was completed in 2010. Construction started in April 2012. The first half, weighing 12,800 tonnes, was moved 112 metres to a holding area in front of unit 4 in April 2014. The second half was completed by the end of 2014 and was joined to the first in July 2015. Cladding, cranes, and remote handling equipment were fitted in 2015. The entire 36,000 tonne structure was pushed 327 metres into position over the reactor building in November 2016, over two weeks, and the end walls completed. The NSC is the largest moveable land-based structure ever built.


Modifications have been made to overcome deficiencies in all the RBMK reactors still operating. In these, originally the nuclear chain reaction and power output could increase if cooling water were lost or turned to steam, in contrast to most Western designs. It was this effect which led to the uncontrolled power surge that led to the destruction of Chernobyl 4 (see Positive void coefficient section in the information page on RBMK Reactors). All of the RBMK reactors have now been modified by changes in the control rods, adding neutron absorbers and consequently increasing the fuel enrichment from 1.8 to 2.4% U-235, making them very much more stable at low power (see Post accident changes to the RBMK section in the information page on RBMK Reactors). Automatic shut-down mechanisms now operate faster, and other safety mechanisms have been improved. Automated inspection equipment has also been installed. A repetition of the 1986 Chernobyl accident is now virtually impossible, according to a German nuclear safety agency report7.


b. Much has been made of the role of the operators in the Chernobyl accident. The 1986 Summary Report on the Post-Accident Review Meeting on the Chernobyl Accident (INSAG-1) of the International Atomic Energy Agency's (IAEA's) International Nuclear Safety Advisory Group accepted the view of the Soviet experts that "the accident was caused by a remarkable range of human errors and violations of operating rules in combination with specific reactor features which compounded and amplified the effects of the errors and led to the reactivity excursion." In particular, according to the INSAG-1 report: "The operators deliberately and in violation of rules withdrew most control and safety rods from the core and switched off some important safety systems."


On the number of deaths due to acute radiation syndrome (ARS), the Expert Group report states: "Among the 134 emergency workers involved in the immediate mitigation of the Chernobyl accident, severely exposed workers and fireman during the first days, 28 persons died in 1986 due to ARS, and 19 more persons died in 1987-2004 from different causes. Among the general population affected by the Chernobyl radioactive fallout, the much lower exposures meant that ARS cases did not occur."


According to the report: "With the exception of thyroid cancer, direct radiation-epidemiological studies performed in Belarus, Russia and Ukraine since 1986 have not revealed any statistically significant increase in either cancer morbidity or mortality induced by radiation." The report does however attribute a large proportion of child thyroid cancer fatalities to radiation, with nine deaths being recorded during 1986-2002 as a result of progression of thyroid cancer.
