4.3.9.3.4 Bio-lock quarantine enclosure - SHM mounted.<br />

HMM<br />

Assessment Study<br />

Report: CDF-20(A)<br />

February 2004<br />

page 328 of 422<br />

The quarantine container shall be of the following size:<br />

OD (mm) ID (mm) Ext. Length (mm) Int. Length (mm) Material Unit Mass (Kg)<br />

360 (enclosure) 350 270 250 Ti 15.4<br />

200 (lid) 50 Ti 7.0<br />

Table 4-34: Quarantine container characteristics<br />

Figure 4-65 shows the bio-lock principle. In summary, the sample containers are placed in the<br />

internal volume. A lid is placed on the container. An explosive charge is set off which welds the<br />

I/F between the lid and Bio-lock container wall and fractures the connection to the outer support.<br />

As stated above, this principle is based upon the Bio-Container principle developed by<br />

JPL/NASA- Ref paper 001CES-131, Dolgin, Sanok, Sevilla & Bement and is adopted for this<br />

study.<br />
