Exam 2 Name 20points 1. You are working as an independent consultant on a case involving the Nuclear Regulatory Commission and the Federal Emergency Mananagement Agency. The case involves the placement of a nuclear generation plant on the southern side of the island of Hawaii. The fate of the case rests in your hands. Here is the information as The site is on the hanging wall of a straight normal fault that extends from the urface to a depth of 4,000 meters e The fault crops out on the side of the island, and shows signs of historic displacement on the order of 100 meters. The fault is dipping at an angle of 70 that is 2km wide at the location of the plant, 1 5km long and 4km deep. The o degrees at the surface, and apparently holds that dip throughout the rock volume The rock volume in question can be approximated as a nearly triangular volum calculated rock volume is 60km3 The density of basalt is roughly 3-3 The plant will add a mass roughly equivalent to 5km of additional basalt The current state of stress on the fault is thought to be within 10% of the "failure point” for the systen The nRC contends that the additional load will not have a significant effect on the state of stress on the fault. fema contends that the additional load will cause a catastrophic failure that could cost thousands of lives a. Determine the state of stress on the fault (ignoring lithostatic stress) for the current system, and for the system after the construction of the plant b. Present a recommendatation to the court regarding the wisdom of constructing the plant based on your calculations October 29. 1999 & " % % , - . / 0 $ 1 % % " " 2 1 2 1 ) " ((( 1 " " (( 1 "" +( "" " % 1 % "" ) % " # " 1 % '(n 1 / En 1 " % #n 1 (3 4 " 5 1 ,- % 6 7 ./0$ " % 8 9 : " "
