Answer:

Nuclear fission is almost 8,000 times more efficient than traditional fossil fuels at producing energy. That's a lot of energy packed into a small space. Nuclear energy is more efficient, which means it uses less fuel to power the plant and produces less waste.

advantages:
-produces no polluting gases
-does not contribute to global warming
-very low fuel costs
-Low fuel quantity reduces mining and transportation effects on environment
-High technology research required benefits other industries
-Power station has very long lifetime

Disadvantages:
-Waste is radioactive and safe disposal is very difficult and expensive
-Local thermal pollution from wastewater affects marine life
-Large-scale accidents can be catastrophic
-Public perception of nuclear power is negative
-Costs of building and safely decommissioning are very high
-Cannot react quickly to changes in electricity demand

) A brick of clay is being dried in a batch dryer using constant drying conditions. You have been asked to determine the amount

dimaraw [331]

Answer:

The drying time is calculated as shown

Explanation:

Data:

Let the moisture content be = 0.6

the free moisture content be = 0.08

total moisture of the clay = 0.64

total drying time for the period = 8 hrs

then if the final dry and wet masses are calculated, it follows that

t = (X0+ Xc)/Rc) + (Xc/Rc)* ln (Xc/X)

= 31.3 min.

In a steady flow device, the properties of the system remains constant with time. a)True b) False

Leviafan [203]

Answer:

True

Explanation:

By definition of steady flow we have

$\frac{\partial f(x,y,z,t) }{\partial t}=0$

where f(x,y,z,t) is any property of the system under consideration

=> f(x,y,z,t) = constant

Exposure to asbestos dust can cause what condition?

Natali5045456 [20]

If you end up breathing asbestos fibers, it can increase the risk of serous diseases. Some examples are lung cancer, mesothelioma and asbestosis. It may also increase your risk for cancers of the digestive system, which includes colon cancer. Asbestos is dangerous when fibers become airborne. That is because once a person ingests or inhales asbestos, the fiber can’t be removable from the body. The fibers can cause irritation and scarring over time if it’s embed into the tissue.

Mariulka [41]

Explanation:

1. Cybersecurity Strategy Development Guide

The Strategy Development Guide defines a road map that PUCs can follow to design and implement

a structured approach for long-term engagement with utilities on cybersecurity matters. The guide

includes examples from PUCs that demonstrate the process steps and highlights the drivers of

successful outcomes. (2018)

2. Understanding Cybersecurity Preparedness: Questions for Utilities

The Questions for Utilities provides a set of comprehensive, context-sensitive questions that PUCs

can ask a utility to gain a detailed understanding of its current cybersecurity risk management

program and practices. The questions build upon and add to those included in previous NARUC

publications. (2019)

3. Cybersecurity Preparedness Evaluation Tool (CPET)

The CPET provides a structured approach for PUCs to use in assessing the maturity of a utility’s

cybersecurity risk management program and gauging capability improvements over time. The

CPET is designed to be used with the Questions for Utilities on an iterative basis to help PUCs

identify cybersecurity gaps, spur utilities’ adoption of additional mitigation strategies, and inform

cybersecurity investment decisions. (2019)

4. Cybersecurity Tabletop Exercise (TTX) Guide

This guide details the steps that PUCs can take to design and execute an exercise to examine utilities’

and other stakeholders’ readiness to respond to and recover from a cybersecurity incident. The

guide also is helpful to PUCs seeking to exercise their own cybersecurity strategies and capabilities.

Exercise scenarios and examples are included. (2020)

5. Cybersecurity Glossary

The Glossary contains cybersecurity terms used throughout the Cybersecurity Manual, as well as

“terms of art” that utilities may use during discussions with PUCs. (2019)

Components of the Cybersecurity Manual can be used individually but are designed to work together.

NARUC’s intent is to provide a comprehensive set of assessment tools that, when applied, provide a consistent,

complete view of utilities’ cybersecurity preparedness.
