Because of licensing requirements and regulation, any product using the LENR reaction will require radiation shielding against X-rays and Gamma radiation need it or not.
It is elegant from an engineering standpoint to kill two birds with one stone by using tungsten as the stuctual material in your reactor core.
This dense element is so hydrogen leakage resentant that it might be terms hydrogen leak proof. It is extremely strong and will resist LENR reaction blast and burn up conditions.
Since radiation shielding will be required anyway, get rid of the lead and use tungsten instead.
The denser the material, the better able it is to protect from radiation. That is why heavy elements absorb X-rays and gamma radiation particularly well. Lead is still the most frequently used shielding material. Because it is a very soft material, it is mostly used only in combination with support structures made of steel.
Tungsten alone can replace a combination of structural materials in your reactor comprising alumina, lead, and stainless steel.
Lead is a toxic material that is harmful to the environment and humans. The onerous recycling process makes lead expensive despite the low initial procurement costs. Many enterprises are therefore looking for a suitable alternative for providing reliable radiation protection.
Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you’ll also reduce administration costs by eliminating the need to obtain special licensing—it’s not required.
Currently in industry that uses nuclear material, tungsten alloys are used for radioactive source containers, gamma radiography, shields, and source holders for oil-well, logging, and industrial instrumentation. High-density alloys also serve as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections. Unlike Lead, tungsten alloys performs even under extreme, high-heat conditions in LENR based applications.
Tungsten heavy alloy has high absorption rate on X rays and gamma rays. Tungsten is 60% better than lead in shielding against X rays and gamma radiation therefore; therefore the multi-material layered structure of your reactor core can be significantly reduced in size.
In your experimentation, even at a very early stage, it is wise to use tungsten to gain experience in its behavior in the core of your reactor since any commercialism product that you will develop will require top of the line radiation shielding.
