Target Production

The paper presents the results of mathematical and experimental modeling of in-line production of inertial fusion energy (IFE) targets of a reactor-scaled design. The technical approach is the free-standing target (FST) layering method in line-moving spherical shells. This includes each step of the fabrication and injection processes in the FST transmission line (FST-TL) considered as a potential solution of the problem of mass target manufacturing. Finely, we discuss the development strategy of the FST-TL creation seeking to develop commercial power production based on laser IFE.

Cryogenic Fuel Target

Inertial fusion energy (IFE) research indicates that the energy generation by means of cryogenic fuel target compression requires that targets must be injected to the target chamber center at a rate of about 6 Hz. This requirement can be fulfilled only if the targets are free-standing. The most interesting results concerning the activity of the Lebedev Physical Institute in the area of free-standing targets (FST) fabrication, characterization and delivery are presented.

Advanced Fuel

In inertial fusion energy (IFE) research, a number of technological issues have focused on the ability to inexpensively fabricate large quantities of free-standing targets (FSTs) by developing a specialized layering module with repeatable operation. Of central importance for the progress towards plasma generation with intense thermonuclear reactions is the fuel structure, which must be isotropic to ensure that fusion will take place. In this report, the results of modeling the FST layering time, $\unicode[STIX]{x1D70F}_{\text{Form}}$ , are presented for targets which are shells of ${\sim}4~\text{mm}$ in diameter with a wall made from compact and porous polymers. The layer thickness is ${\sim}200~\unicode[STIX]{x03BC}\text{m}$ for pure solid fuel and ${\sim}250~\unicode[STIX]{x03BC}\text{m}$ for in-porous solid fuel. Computation shows $\unicode[STIX]{x1D70F}_{\text{Form}}<23$  s for $\text{D}_{2}$ fuel and $\unicode[STIX]{x1D70F}_{\text{Form}}<30$  s for D–T fuel. This is an excellent result in terms of minimizing the tritium inventory, producing IFE targets in massive numbers ( ${\sim}$ 1 million each day) and obtaining the fuel as isotropic ultrafine layers. It is shown experimentally that such small layering time can be realized by the FST layering method in line-moving, high-gain direct-drive cryogenic targets using $n$ -fold-spiral layering channels at $n=2,3$ .

Decision Making Model

The paper presents a new approach to the development strategy of the production system based on a formalized description of bifurcations arising in the creative activities of specialists as part of the solution to the problem of assessing the usefulness of targeted changes in the principles and approaches in the organization of production. In the framework of the producer-production approach to the analysis of production, the term bifurcation producer is proposed, describing a targeted change affecting the development of production. An important task is found to create a unified model that describes the relationship between a person as a thinking active subject and production. This description allows making objective decisions on the production development strategy. A formal-logical apparatus is proposed, that uses as identifiers the characteristics deter-mining the image of production or thought activity, which includes creation of a description mech-anism on the basis of common identifiers for the decision-making model for the production development strategy. There has been illustrated the scheme of interaction of an active thinking person and production. A formal logical apparatus is proposed, using identifiers as characteristics determining the image of production activity or mental activity; including the creation of a description mechanism based on common identifiers for a decision-making model for a production development strategy. The choice of the development strategy of the production system is proposed to be carried out on the basis of the methodology of structural similarity of production types. A similarity matrix for the similarity of bifurcation producers is presented, which contains the following bifurcation producers: ergatic model of transformation of production, division of labor, in-line production, technological specialization, ergodynamic cooperative. The purpose of the development of the production system in the desire to approach the appearance of individual-paper-only production has been substantiated. It is stated that the efficient producer of the strategic development process is the bifurcation producer, which is the result of creative activity. As a primary measure of performance of strategy of development of production system there has been proposed the approximate method of calculating the similarity factor of the bifurcation producers for the individual paper-only production.

This research intended  to evaluate the development strategy of Marine Fish Hatchery Unit at Gumilamo Island, North Halmahera. Analysis SWOT was used to determine the development strategy. Data were collected by questionnaire, interview and literature relevant to the research. SWOT analysis showed the internal and external factors that affected the development of Marine Fish Hatchery at Gumilamo island. The strenght were location, water quality , local government support, and availability of seeds and feed. Weakness were lack of public interest, lack of extension and human resources. Opportunity were the high value of the sale, business opportunities and  local government regulation. Treat were  dependence on fishing effort and safety.   Keywords : hatchery, gumilamo, north halmahera, SWOT analysis
