Responsibility of operator

At low levels be sure the counting-rate meter is alive. It is the only source of information at such levels, and unless its pointer gives evidence of responding to signal it would be foolhardy to attempt reactor operation. 

After every scram be sure to turn switch S-2B (intermittent, neutral, high) to neutral.. Otherwise there may be nothing to prevent the shim rod holders, lowered automatically after rods are dropped, from picking up rods and starting (possibly even high speed) withdrawal. 

For smooth change of reactor level under servo control, keep the shim rods in step with the motor-operated rheostat. In particular, try to avoid letting the regulating rod get within 5 in. of full insertion, since at this point it automatically calls for reverse. 

Avoid leaving any shim rods fully inserted. Any such rod is incapable of contributing to the effectiveness of a scram. To have full benefit of prompt scram protection, all rods should be in position to contribute some effect.  

Never permit the bolts holding down the top plug of the reactor to be loosened unless the reactor is first scrammed. A serious accident could occur if the. plug were lifted by the crane or by. water pressure while the rods are still held.

Too many firms focus upon the belief that the only responsibility of operations (manufacturing, formulation, packaging, labeling, etc.) is to make product. The role of operations goes well beyond this notion, and without this department s key involvement, repeatable product quality will be elusive. An overview of operations responsibilities is... 

It is important that roles and responsibilities of operators be clearly defined. However, use of proper nouns (names) must be avoided. Timelines listed in the SOP should be realistic.

Once the facility s management agrees that a package is ready to be turned over, the construction company will prepare a formal turnover letter. The letter, which is signed by both the constrac-tion and operations teams, states that the turned over section is ready for operations and is now the responsibility of operations. Once this letter has been signed, construction can no longer work on... 

As an alternate or addition to scenario assessments, simulated exercises or dry-runs could be developed to test the effectiveness of the new organization. This could be similar to table-top exercises commonly run by companies to test the effectiveness of the emergency response plans as well as the use of process simulators to test response of operations personnel to process upsets. The assessment should verify that individuals can complete their critical safety responsibilities in a reasonable amount of time. 

The SEMS rule administered by BSEE differs from all other rules enacted under OCSLA because it directly addresses the safety management responsibilities of operators in a performance-based rule that requires operator conduct of twelve broadly defined safety management functions. It is featured and extensively discussed in all major post-Macondo reports that address the need for improving the accident prevention regime. SEMS adopts and makes mandatory the voluntary management practices of API s Recommended Practice 75, as discussed earlier. As a result, the rule also incorporates by reference and makes mandatory and enforceable the... 

Responsibility of Operator. The operator should realize that a prolonj ed intensive effort went into design of the control system. It is, however, most unlikely that this effort could possibly have provided for every conceivable operational situation. Nevertheless, the operator would do well, when he feels unduly constrained or frustrated by the control system, to try to keep in mind all the implications of his intended action. It is probable that, as operating experience accumulates, it will become evident that some changes in the control system could profitably be made. Until such experience is accumulatedi it would seem reasonable to ask the operator to learn to live with the system as designed. 

On this basis, the responsibilities of operators for monitoring should be...

The Conduct of Operations Manual, Section 3, "Operator Shift Responsibilities," defines the responsibilities of operators while on shift. 

If a situation arises whereby formation fluid or gas enters the bore bole the driller will notice an increase in the total volume of mud. Other indications such as a sudden increase in penetration rate and a decrease in pump pressure may also indicate an influx. Much depends on a quick response of the driller to close in the well before substantial volumes of formation fluid have entered the borehole. Onoe the BOP is closed, the new mud gradient required to restore balance to the system can be calculated. The heavier mud is then circulated in through the kill line and the lighter mud and influx is circulated out through the choke line. Once overbalance is restored, the BOP can be opened again and drilling operations continue. 

It is no longer acceptable in most countries to treat decommissioning as an issue that can be ignored until the end of a project. Increasingly operators are being required to return industrial sites to their original condition after use. Many operators now perform a base line survey before they build on an area so that the impact of operations can be quantified, and in some cases so that they are not held responsible for the pollution of previous site owners. 

The equation system of eq.(6) can be used to find the input signal (for example a crack) corresponding to a measured output and a known impulse response of a system as well. This way gives a possibility to solve different inverse problems of the non-destructive eddy-current testing. Further developments will be shown the solving of eq.(6) by special numerical operations, like Gauss-Seidel-Method [4]. 

Unique response A contour has to provoke an unique response of the operator. 

Because of its small size and portabiHty, the hot-wire anemometer is ideally suited to measure gas velocities either continuously or on a troubleshooting basis in systems where excess pressure drop cannot be tolerated. Furnaces, smokestacks, electrostatic precipitators, and air ducts are typical areas of appHcation. Its fast response to velocity or temperature fluctuations in the surrounding gas makes it particularly useful in studying the turbulence characteristics and rapidity of mixing in gas streams. The constant current mode of operation has a wide frequency response and relatively lower noise level, provided a sufficiently small wire can be used. Where a more mgged wire is required, the constant temperature mode is employed because of its insensitivity to sensor heat capacity. In Hquids, hot-film sensors are employed instead of wires. The sensor consists of a thin metallic film mounted on the surface of a thermally and electrically insulated probe. 

How well the drilling fluid fulfills these functions is determined primarily by the response of the well. The whole drilling operation suffers if the fluid is not adequate. In extreme cases, drilling may be stopped or a hole may have to be redfilled. A variety of physical and chemical properties are monitored to ensure satisfactory performance and guide fluid formulation and treatment (21,22). 

There are important figures of merit (5) that describe the performance of a photodetector. These are responsivity, noise, noise equivalent power, detectivity, and response time (2,6). However, there are several related parameters of measurement, eg, temperature of operation, bias power, spectral response, background photon flux, noise spectra, impedance, and linearity. Operational concerns include detector-element size, uniformity of response, array density, reflabiUty, cooling time, radiation tolerance, vibration and shock resistance, shelf life, availabiUty of arrays, and cost.
