The document is dated August 9, 2012, however this is backdated by one year. The correct date is August 9, 2013.
What I am gong to try to find out now, is what actions the NRC went through in order to produce the above document.
I requested the basis for the following:
1.2 The HCVS shall include the following design features:
1.2.1 The HCVS shall have the capacity to vent the steam/energy equivalent of 1 percent of licensed/rated thermal power (unless a lower value is justified by analyses), and be able to maintain containment pressure below the primary containment design pressure.
Page 3 of 3 of the August 12, 2013, document ML13221A011, lists 10 references as follows:

1979.

ADAMS Accession No.: ML13221A011
It is noteworthy that of the ten references, reference 8, IAEA-TECDOC-1661, July 2011, is the only reference that has been published since the Fukushima detonations. It is also noteworthy that although reference 8 itself has 100 pertinent references in the matter of Mitigation of Hydrogen Hazards in Severe Accidents in Nuclear Power Plants, none of the other nine references of document ML13221A011 are cited.
On page 1 of 3 of is the assertion:
Generic Letter 89-16 (Reference 3) related to installation of hardened wetwell vents was issued in September 1989 and stated that the system installed by Boston Edison Company at the Pilgrim Nuclear Power Station and associated analysis was acceptable. The design analysis included a vent design objective of venting approximately 1 % of decay heat for a 56 psi saturated steam conditions in the torus.
So, I downloaded reference 3, but the attachment that discusses the Pligrim analysis is not included. I'll contact NRC's PDR and ask for the attachment.
The NRC's PDR very courteously provided the best copy that they could. I e-mailed the following request:

The
document that the PDR courteously sent is not completely readable, and those
parts that are readable are not expediently readable. You should recognize that
the matter is of intense importance. Accordingly, you should take actions that
will provide a very readable document in ADAMS, and those actions should proceed
immediately.

Thank
you for contacting the NRC’s Japan Lessons-Learned Project Directorate. Your
comments will be considered to the extent possible.

And, we pay those clowns for that kind of service. I suppose the staff of the NRC's PDR may be chastised for providing courteous attention to my request; that courteous attention is beyond the requirements on NRC regulations.
