Sommario/riassunto |
|
On May 22, 1863, after two failed attempts to take the city of Vicksburg by assault, Major General Ulysses S. Grant declared in a letter to the commander of the Union fleet on the Mississippi River that the nature of the ground about Vicksburg is such that it can only be taken by a siege. The 47-day siege of Vicksburg orchestrated by Grant resulted in the eventual surrender of the city and fulfilled a major strategic goal for the Union: command of the Mississippi River for the remainder of the war. In this revealing volume, Michael B. Ballard offers the first in-depth exploration of Grant s thoughts and actions during this critical operation, providing a never-before-seen portrait of the general in the midst of one of his most notable achievements. After an overview of Grant s early Civil War career from his first battle through the early stages of the attacks on Vicksburg, Ballard describes in detail how Grant conducted the siege, examining his military decisions, placement of troops, strategy and tactics, engineering objectives, and relationships with other officers. Grant s worried obsession with a perceived danger of a rear attack by Joseph Johnston s Confederate army, Ballard shows, affected his decision making, and shows how threats of Confederate action occupied more of Grant s time than did the siege itself. In addition, Ballard soundly dispels a false story about |

Grant s alleged drinking binge early in the siege that has been taken as truthful by many historians, examines how racism in Grant s army impacted the lives of freed black people and slaves in the Vicksburg area, and explores Grant s strained relationship with John McClernand, a politically appointed general from Illinois. The book concludes with the surrender of Vicksburg on July 4, 1863, the expulsion of Johnston and his army from the region, and demonstrates the impact of the siege on the outcome on the short and long-terms of Grant s military career. By analyzing Grant s personality during the siege and how he dealt with myriad issues as both a general and an administrator, "Grant at Vicksburg" offers a revealing rendering of the legendary general.

The Second World War introduced the world to nuclear weapons and their consequences. Behind the scene of these nuclear weapons and an aspect of their consequences is radioactive waste. Radioactive waste has varying degrees of harmfulness and poses a problem when it comes to storage and disposal. Radioactive waste is usually kept below ground in varying containers, which depend on how radioactive the waste it. High-level radioactive waste (HLW) can be stored in underground carbon-steel tanks. However, radioactive waste must also be further immobilized to ensure our safety. There are several sites in the United States where high-level radioactive waste (HLW) are stored; including the Savannah River Site (SRS), established in 1950 to produce |

plutonium and tritium isotopes for defense purposes. In order to further immobilize the radioactive waste at this site an in-tank precipitation (ITP) process is utilized. Through this method, the sludge portion of the tank wastes is being removed and immobilized in borosilicate glass for eventual disposal in a geological repository. As a result, a highly alkaline salt, present in both liquid and solid forms, is produced. The salt contains cesium, strontium, actinides such as plutonium and neptunium, and other radionuclides. But is this the best method? The National Research Council (NRC) has empanelled a committee, at the request of the U.S. Department of Energy (DOE), to provide an independent technical review of alternatives to the discontinued in-tank precipitation (ITP) process for treating the HLW stored in tanks at the SRS. Alternatives for High-Level Waste Salt Processing at the Savannah RIver Site summarizes the finding of the committee which sought to answer 4 questions including: "Was an appropriately comprehensive set of cesium partitioning alternatives identified and are there other alternatives that should be explored?" and "Are there significant barriers to the implementation of any of the preferred alternatives, taking into account their state of development and their ability to be integrated into the existing SRS HLW system?" |
