moniz: yes.e have discussed that. charlie: what about the idea of their desire to do r&d on centrifuges? if it goes for 10 years and goes to the end of the agreement, they have done a lot of research on centrifuges. they will be able to come at the end of the decade, be able to be improved in their ability to enrich uranium. sec. moniz: the r&d issues were a point of contention in the discussion. what i want to emphasize is, in the first 10 years, there will be no enrichment by any advanced centrifuge. only the original ir one will be allowed in the first 10 years. in fact, in that decade they -- there will be a rollback of some of their r&d activities, but they were -- will be able to make progress. however, the ability to use advanced centrifuges is part of our breakout calculation and consideration. again -- charlie: it will still take them a while? sec. moniz: a more limited program is on the books. the reality is in 2003, negotiations in 2003 2 -- to 2005 would have a very different set of f

thank you, secretary moniz. in response to senator cantwell, you touched on the properties and characteristics of tidal oil specifically and specifically the characteristic of combustibility, and we've seen these crude-by-rail accidents that have led to some pretty spectacular explosions and in some cases tragedy, 47 people killed in quebec during an accident. so let me ask about a very specific property which is vapor pressure. it causes, i understand it, by liquid, natural gases -- >> ngls. >> -- yeah, that are particularly explosive. as you may know on april 1st, north dakota -- or since then has been requiring vapor pressure bakken crude to be limited to 13.7 pounds per square inch before it's loaded into the railcars, but the big explosion in west virginia, the vapor pressure of that oil was at 13.9 psi. my question is whether the department of energy is working with the department of transportation in order to access the safety benefits of lowering crude oil vapor pressure before it's loaded onto trains. >

moniz: pleased to be here. charlie: we can talk about energy in a broader sense and what you think of where we are in terms of climate and other issues. you have become famous to all of us sitting next to john kerry. the interesting fact is the foreign minister was at the table a few weeks ago. someone you knew at m.i.t. when you were both students.

tonight, ernest moniz, u.s. secretary of energy and one of the principal negotiators with the iranians over nuclear weapons. >> certainly when i was introduced into the negotiations it was for addressing technical dimensions, be it enrichment, plutonium production in reactors et cetera so certainly for that part of the agreement, you know i am certainly working intensely with members of congress, but don't forget there are many other dimensions to this agreement. >> rose: ernest moniz for the hour next. >> rose: funding for "charlie rose" has been provided by: >> rose: additional funding provided by: >> and by bloomberg, a provider of multimedia news and information services worldwide. captioning sponsored by rose communications from our studios in new york city, this is charlie rose. >> rose: ernst ernst is here. he is the secretary of energy for the united states.

secretary of energy ernest moniz. >> when i was introduced into the negotiations it was for technicalera. so certainly for that part of the agreement i am certainly working intensely with members of congress. but don't forget there are many other dimensions to this agreement. the sanctions relief, the military dimensions. >> rose: okay. where secretary kerry obviously is the principal spokesman for that. secondly, there are broader issues being introduced into the discussion about the nature of the negotiation, not about the results of the negotiation, but the nature of the negotiation and for those clearly secretary kerry and the president are quite in the lead. >> rose: the iranians have said at this table three presidents of iran, they have said we don't want nuclear weapons. they say that all the time. how do you assess that? >> well, first of all, let me say, we hope it's true and this is what this agreement is, as i said earlier is built for the long term, because we have specific restrictions that go up to 25 years and some basically are in effect forever. so the whole idea is,

first, let me note that secretary of energy moniz and i fully share the thoughts expressed by tom countryman this morning and share the view that the proposed agreement provides a comprehensive agreement for nuclear cooperation with china while fully protecting and advancing u.s. interests and policy objectives with respect to nuclear nonproliferation and the peaceful uses of nuclear energy. thus, the department of energy supports entry into force this agreement following the requisite congressional review period. this agreement is fully consistent with the law and incorporates all of the terms required by section 1-2-3 of the atomic energy act. moreover, it reflects important advances over the current agreement, several of which we discussed during classified agreements during both members and staff of this committee. specifically, the successor agreement enhances the provisions under which we would allow china to enrich and reprocess u.s.-obligated nuclear material by requiring that such enrichment and reprocessing take place only at facilities in china. that fall under their international

the issue is the monization rate. it's 1.97%. so, it's still fairly low. that's the issue.urse makes less money. cfo maggie wu talking about how the company was committed to having margins in the high 50s in the core business going forward. the margin came down to 49% in this quarter. that is something that the company will definitely be watching. and i should note, andrew, that maggie, the cfo, also did talk about the fact that jack mu reported some comments about a hiring freeze. that took the stock down for the last five days. she said look this is something we've done in the past. focusing on efficiency. we will still have onboarding of all the people we hired and no new net hires. something they did in 2012. >> the stock dropped because they were holding the line on unemployment. usually it's the opposite. >> when you ahavehave a company. >> we're not hiring because we need to double down on what we have and maybe we've been spending too much money and issuing too much stock as compensation. that gives you a little bit of a pause. jack mu did send an e-mail saying he w
