[Q]: What is the answer for the question: How many years did the cleanup that was estimated by the company that was the longest occupant of the Quehanna facility to take six months actually take? from the following article ?  In 1967, Pennsylvania leased the reactor complex to the Nuclear Materials and Equipment Corporation (NUMEC), which already had a federal license to work with nuclear materials. NUMEC, which soon became a subsidiary of Atlantic-Richfield Corporation (ARCO), set up a large irradiator in what had been the reactor pool. The irradiator contained over 1 million curies of cobalt-60 to produce intense gamma rays, which were used to sterilize medical equipment and irradiate food and wood. In the spring of 1967 the state had concluded that radiation contamination at the Quehanna site "could never be completely cleaned up", and so was glad to find a tenant with nuclear experience. A group of NUMEC employees discovered that irradiating hardwood treated with plastics produced very durable flooring. In 1978 they formed PermaGrain Products, Inc. as a separate company from ARCO, and purchased the rights to the process as well as "the main irradiator, a smaller shielded irradiator and related equipment". PermaGrain sold the flooring for use in basketball courts and gymnasiums, and was the longest occupant of the Quehanna facility, operating there from 1978 to December 2002. PermaGrain also let Neutron Products, Inc., a Maryland company, do cobalt-60 work in its hot cells, which required an amendment of their license from the Nuclear Regulatory Commission (NRC, the successor to the AEC).In 1993, strontium-90 contamination in the reactor facility led the NRC to require PermaGrain to begin decontamination work, and the Pennsylvania DEP commissioned a "site characterization study". In 1998, a firm named NES began the cleanup work; they changed their name to Scientech in 1999 and to EnergySolutions in 2006. The cleanup was originally estimated to take six months; by 2006 it had taken 8 years and cost $30 million. According to the Pennsylvania Department of Environmental Protection's (DEP) Bureau of Radiation Protection: "Inadequate characterization of the site and the presence of ongoing industrial operations resulted in many...

input: Please answer the following: What is the answer for the question: What was the title of the person who was taken away and beheaded on Tower Hill? from the following article ?  When Richard II was crowned in 1377, he led a procession from the Tower to Westminster Abbey. This tradition began in at least the early 14th century and lasted until 1660. During the Peasants' Revolt of 1381 the Tower of London was besieged with the King inside. When Richard rode out to meet with Wat Tyler, the rebel leader, a crowd broke into the castle without meeting resistance and looted the Jewel House. The Archbishop of Canterbury, Simon Sudbury, took refuge in St John's Chapel, hoping the mob would respect the sanctuary. However, he was taken away and beheaded on Tower Hill. Six years later there was again civil unrest, and Richard spent Christmas in the security of the Tower rather than Windsor as was more usual. When Henry Bolingbroke returned from exile in 1399, Richard was imprisoned in the White Tower. He abdicated and was replaced on the throne by Bolingbroke, who became King Henry IV. In the 15th century, there was little building work at the Tower of London, yet the castle still remained important as a place of refuge. When supporters of the late Richard II attempted a coup, Henry IV found safety in the Tower of London. During this period, the castle also held many distinguished prisoners. The heir to the Scottish throne, later King James I of Scotland, was kidnapped while journeying to France in 1406 and held in the Tower. The reign of Henry V (1413–1422) renewed England's fortune in the Hundred Years' War against France. As a result of Henry's victories, such as the Battle of Agincourt, many high-status prisoners were held in the Tower of London until they were ransomed.Much of the latter half of the 15th century was occupied by the Wars of the Roses between the claimants to the throne, the houses of Lancaster and York. The castle was once again besieged in 1460, this time by a Yorkist force. The Tower was damaged by artillery fire but only surrendered when Henry VI was captured at the Battle of Northampton. With the help of Richard Neville, 16th Earl of Warwick (nicknamed "the Kingmaker")...

Problem: What is the answer for the question: What is the exact title of the portrait featuring the children of Ellis Agar, 2nd Earl of Normanton? from the following article ?  In February 1828, shortly before his 41st birthday, Etty soundly defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist. By this time, complaints about his supposed indecency were beginning to resurface. All but one of the 15 paintings Etty exhibited at the Royal Academy in the 1820s had included at least one nude figure, and Etty was acquiring a reputation for using respectable themes as a pretext for nudity.For the 1828 Summer Exhibition Etty exhibited three pictures; The World Before the Flood, Venus, the Evening Star and Guardian Cherubs. (The latter was a portrait of the children of Welbore Ellis Agar, 2nd Earl of Normanton, and was the only non-nude painting exhibited by Etty at the RA in the 1820s.) Although similar to his earlier works, they were technically more accomplished. Both The World Before the Flood and Venus attracted positive reviews in the press and were sold during their exhibition for substantial sums, although the purchase by the Marquess of Stafford of The World Before the Flood—a work containing scantily clad figures of both sexes—drew a pointed comment in The Gentleman's Magazine that it "will serve to accompany the private Titians of that nobleman". Despite the increasing number of complaints in the press about his use of nudity, respect for Etty from his fellow artists continued to rise, and in 1828 the British Institution awarded him £100 in recognition of his talent. As soon as the 1828 Summer Exhibition was over, Etty stopped work on other projects to concentrate on a diploma piece, without which he could not become a Royal Academician. This piece, Sleeping Nymph and Satyrs, was presented to the Academy in October, and in December 1828 Etty became a Royal Academician. It appears to me then that virtuous happiness being our lawful aim in life, that having Academic Rank and Fame the next thing to be considered (if God approve) is to seek that Decent Competency which shall make my latter days comfortable...
