Technical specification Temperature

The accelerator is used as radiation source in the development of new dosimetry systems (physical and chemical) and in the characterization of existing dosimeters in different conditions (a water cooled tantalum converter is used for the generation of X-ray and there is the possibility of controlling the temperature of small samples under irradiation). In Table I the technical specifications of the accelerator are reported. 

The energy performance of a dryer and a drying process is characterized by various indices such as volumetric evaporation rate, surface heat losses, steam consumption, unit heat consumption, and energy (thermal) efficiency. Of all these indices, the energy efficiency / is most frequently quoted in technical specifications. It commonly relates the energy used for moisture evaporation at the solids feed temperature ( , ) to the total energy supplied to the dryer ( ,) ... 

Because temperature is critical in processing, it is important to exercise very tight control. Mould cavities should be within 2 °C of the experimentally determined optimum working temperature. For general rubber mouldings, where the rubber modulus has little bearing on service requirements, a wider tolerance may be acceptable, albeit at the expense of profit Components with high technical specifications need carefully controlled conditions. 

Pressure-temperature limitations and additional information are described in the Technical Specifications. The pressure-temperature limit curves provided have been prepared in accordance with Appendix G, ASME Code, Section III. Maintenance of Reactor Coolant System pressure and temperature within these prescribed limits ensures that the integrity of the reactor coolant pressure boundary is maintained. 

MIMS recorder "A" and the associated RC-415 annunciator continues to monitor the Disassembly Basin temperatures (Technical Specification 3.9.4.1) (Ref 2<28). MTMS recorder B and the bulk moderator Strip Chart Recorder have been turned off The utdown alarm panel bulk moderator alarm has been de-ener ed. 

Table 3 lists technical specifications for small autonomous reactors Table 4 contains specifications for water cooled reactors Table 5 gives data for liquid metal cooled reactors and Table 6 presents the characteristics for high temperature lead, gas, or molten salt cooled reactors. 

The SPI kit covers the primary processing machine communication protocol with chillers, blenders, dryers, water systems, discrete mold-temperature controllers, and the like. The protocol provides for centralized setup and monitoring of auxiliaries by the primary machine. The test simulation software that is a key part of the kit ensures uniform interpretation of technical specifications. It is a combination of a detailed technical specification of hardware requirements such as the type of cable, the connector and electrical interface, and software requirements. The kit protocol shows how electronic information moves through the system. 

There have been numerous reported incidents of pressure transients in PWRs where Technical Specification pressure and temperature limits of the RCS have been exceeded. The majority of these events occurred while the reactor was in startup or shutdown conditions and at low reactor vessel temperatures. The issue is the reliability of the cold overpressure protection system and especially the safety and relief valves situated either on the pressurizer or RHR systems. The protection systems in US plants used to mitigate and reduce the potential for these events are termed low temperature overpressure protection (LTOP) systems. 

The US primary system safety and relief valves have been qualified by testing for the design-basis fluid inlet conditions In addition to hot steam conditions, the PORVs were tested for representative low temperature liquid flow, and the safety valves were tested at representative hot liquid flow The NRC required that the reliability of the PORVs be improved to provide better low temperature overpressure protection (LTOP) and better operation at operating temperature Better maintenance and improved Technical Specifications were implemented... 

As a short term corrective action, it was decided that a reduction of the maximum control room temperature and an increase of the surveillance requirements should be defined in the Technical Specifications. 

The startup of an inactive RCP at an incorrect temperature is not assessed. Technical Specification 3.4.4 (see Chapter 16 of Reference 5.6) requires all RCPs to be operating during... 

The 130°F temperature limit is based on protection of demineralizer resins (from breakdown at high temperatures) and humidity control. Although not so stated in the Technical Specifications, basis for the 130°F scram is the temperature assumed for some of the safety analyses. (See Tech Spec 3.8.2.3(3), for example).

The plant technical specifications are typically defining the pressure/temperature limitation which are applicable during shutdown operation. In addition, some plants have backfitted their technical specifications to prohibit the use of specific pumps (i.e. those with high head delivery) to fill the reactor, or require the operability of adequate relief capacity during periods when the increased risk of over-pressurisation exists. 

The 105 Technical Specifications specify that the.,safety rods, which are cadmium rods, must be capable of falling into the core via gravity ancj overcoming the reactivity contained in the temperature defect to render the core subcritical. Concurrently, upon .a scr am, the cadmium rods that are a part of each control rod septifdi1.-w.ill be. driven into the core at high speed to provide negative reactivity icpmpensation for the positive reactivity insertion that will occur when t.he xenon in,the core has decayed away.
