Ease of Access There are many advantages to using secondary research. Instead, there is a low-pressure vessel and pipes for molten salt constructed of relatively thin materials.
LFTRs can include a freeze plug at the bottom that has to be actively cooled, usually by a small electric fan. There is no water or hydrogen in the reactor that can cause a large pressure rise or explosion as happened during the Fukushima Daiichi nuclear accident.
Disadvantages of Spiral model: Almost all of the fuel is therefore only one step away from becoming a transuranic long-lived element.
The gas mainly He, Xe and Kr is held for about 2 days until almost all Xe and other short lived isotopes have decayed. If the cooling fails, say because of a power failure, the fan stops, the plug melts, and the fuel drains to a subcritical passively cooled storage facility.
It is important for the researcher to identify, reduce, and manage the disadvantages that are accompanied by the use of secondary research.
Decommissioned uranium bombs have enough enrichment, but not enough is available to start many LFTRs. Much of the high cost was caused by the unexpected evolution of fluorine and uranium hexafluoride from cold fuel salt in storage that ORNL did not defuel and store correctly, but this has now been taken into consideration in MSR design.
This data can be gathered from government records, books, trade associations, national or international institutes, statistics agencies, etc. Factors to be considered while collecting data from secondary sources: These sources can provide valuable data such as the U.
Such a reactor would not reprocess fuel while operating. Primary market research can be quantitative or qualitative in nature. The research is carried out after getting some knowledge from the secondary sources eg.
MSR designs have to arrange for this replacement. This raises the problem of how to start the reactors in a short time frame. The Disadvantage of Bias and Dishonesty When surveys, interviews, questionnaires and focus groups are used to collect information, there are potential problems with bias and dishonesty.
Fission products at that point, in about years, are less radioactive than natural uranium. This requires careful design and freeze protection in the containment and heat exchangers.

Exposure to different fields and interests allows a person to choose between a number of options and hone in on the one field that they have the ability to excel in. The Advantages & Disadvantages of Secondary Research by Devra Gartenstein - Updated June 28, As a business owner, you do marketing research all day every day as you watch customers respond to products on your shelves and observe which times of.
THE RESEARCH QUESTION Managers' needs for information are the primary source of problem definition and the research question.
Managers need information to make educated decisions arising from unanticipated as well as planned changes. The major disadvantage of primary research is the huge cost involved in gathering information. Similarly, it consumes a lot of time since a researcher has to prepare for the study, gather details, and process the information into coherent and logical results.
Primary research is the process of. Tim Friesner. Marketing Teacher designs and delivers online marketing courses, training and resources for marketing learners, teachers and professionals.Advantages and disadvantages of primary and secondary research
