Control rods are partially removed from the core to allow the nuclear chain reaction to start up and increase to the desired power level. Neutron flux can be measured, and is roughly proportional to reaction rate and power level. To increase power output, some control rods are pulled out a small distance for a while.
An overhead power line is one example of a transmission line. At power system frequencies, many useful simplifications can be made for lines of typical lengths. For analysis of power systems, the distributed resistance, series inductance, shunt leakage resistance and shunt capacitance can be replaced with suitable lumped values or simplified ...

A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
MDSS – measured depth referenced to mean sea level zero datum – "subsea" level; MDT – modular formation dynamic tester, a tool used to get formation pressure in the hole (not borehole pressure which the PWD does). MDT could be run on Wireline or on the Drill Pipe; MDR – mud damage removal (acid bullheading) MEA – monoethanolamine
The [main] field of the drawing, as opposed to other areas of it, such as the parts list , general notes (G/N), flagnotes , title block , rev block , bill of materials (B/M or BoM or BOM), or list of materials . Rationales for drawing changes that are noted in the rev block often use these abbreviations for brevity (e.g., "DIM 14.00 was 12.50 ...
